Re: The really difficult question
Nah, you can never have enough! I just acquired another Spottie and a couple of lens, so I probably won't buy any more bodies until the DSLR question is answered, but I really would like a longer lens than 400, so maybe a converter will pop into my hands sometime soon - can't justify another lens to the War Office yet!

If you are used to the size of the F2, then the F5XB bag is much smaller. For me, the F5XB will carry the zx-5n, battery grip, FA28-105/3.2-4.5 quite comfortably. It will also hold my check book length wallet, keys, cell phone, and a couple rolls of film in the main compartment. On the outside, I can slip a few pens and a small notebook. The best part is that the bag has a zipper for security.

Re: Bug in light metering on 5N body???
I can't believe it and I am very surprised - I just made today many tests with bracketing and manual exposure correction with my Pentax MZ-5N, Takumar SMC 300/4 lens and m42/K adaptor (original Pentax adaptor, made in Japan). The tests show me clearily that I MUST manually and every time correct exposure by exactly minus 1EV to achieve proper pictures! I have used AV priority and worked on diaphragme stopped down. Have you encountered the same problem or my body just goes wrong??? I do not know if this is the same problem, but I have discovered the problem with Z-1p and M135/3.5 too. I have done a few tests and I am certain when this lens is used on the Z-1p, -2/3EV is required. I believe other K/M lenses have the same problem too. regards, Alan Chan _ Add photos to your e-mail with MSN 8. Get 2 months FREE*. http://join.msn.com/?page=features/featuredemail
Re: Domke bags question
If anybody here tried it, how do you like the F6? And how is the space organised in the F5 satchel? I would be much grateful for some quickndirty digital photos of the bag filled with equipment. Saundersgroup/domke webpage doesn't have any drawings/photos of the inside of it. I have been using the F6 for 3-4 years now and it is my primary choice so far. It works the same way as the F2 except it is smaller, and shorter which could be a major consideration if you have long lenses. For instance, the F*300/4.5 would fit in this bag without the tripod collar, but I have to arrange my other lenses so they won't rub and scratch each other while carrying on the shoulder. The paint of my A70-210/4 was scratched because of this. (But you can use the F2 insert to solve this problem, although the insert doesn't "stick" to the F6 like the original insert does) Also, the lens hood of the FA*200/2.8 doesn't fit because it is too wide (I suppose the A* should have no problem because of the built-in hood). Another problem I have experience is that it could be difficult to put the camera back into the bag if the bag was carrying on the shoulder. The reason is that it doesn't have a rigid base board like the F2 does. I have to use one hand to support the bottom of the bag while trying to squeeze the camera into it. For this reason, I often put the bag on the floor. The last problem I have found is that when the bag is fully loaded, the narrow strap doesn't spread the weight well. But this problem could be solved in Winter because the layers of clothes I wear. Other than that, it is still a comfortable bag to carry and won't slip off the shoulder (but the F803 is better, because of its shape I suppose). regards, Alan Chan _ The new MSN 8: smart spam protection and 2 months FREE* http://join.msn.com/?page=features/junkmail

Re: Re[4]: Diaphragm actuator precision survey

I had a chance to ask directly to Pentax Japan and obtained the explanation but unfortunately lost it. As I remember it, it goes like this; 1. Pentax cameras are actually calibrated for either negative or positive film. I do not remember which one, but from what you and others are saying, it must be calibrated for slides. I thought it was the other way around though. I got exact EV range over the entire ISO range. Too bad I no longer have it. 2. When you load the film, camera reads whether it is a negative or positive film through the metal bar code on the film cartridge. I thought the bias is only for the negative film but not as much as 1EV. 3. Canon has the opposite setting/calibration. 4. I do not remember if this intentional calibration was for the entire line of Pentax SLRs or perhaps pz-1p had a opposite setting. I know this does not answer much to your concern (might only confuse you :-), but I know for the fact that there is an intentional bias built into the metering of Pentax camera. Cheers, Ken

The distortion of the zoom is really disgusting. Also, rotating front element. Is it an FAJ? No interchangeable viewfinders on the body.

Re: *ist and the lens mount.
This is pretty much what I have been suggesting for awhile now. Anyway, the *ist D was initially made with the same crippled mount but as I have said a few days ago, Pentax is apparently working on modifications and the *ist D design isn't finalized yet. So theres still hope for the digital version. Interestingly (if I'm not reading too much into it), the data file says the *ist uses Kaf mount but is compatible wth both Kaf2 and Kaf mount. This opens for that the *ist may have Kaf3 mount. Pål

That makes sense. But all the A lenses have only one contact, don't they? Sounds like electric resistance values to me. That alone can't tell the camera house the absolute value of the largest aperture.

Re: Is flare bad?
Effects often called "flair" are caused by: Reflections. - Produces defined "ghosts". Bubbles in the glass. - Raises level of general light scatter reducing contrast. Other imperfections in the glass. - Raises level of general light scatter reducing contrast. Particles in the glass. - Raises level of general light scatter reducing contrast. Imperfections on the coatings. - Raises level of general light scatter reducing contrast. Imperfect surface polishing of the lens. - Raises level of general light scatter reducing contrast. Reduces sharpness. Gook on the lens. (clean it.) - Raises level of general light scatter reducing contrast. Can produce neat streaking rain effect. Scratches. - Raises level of light scatter reducing contrast. Overexposed areas produce "star streaks" normal to the direction of the scratch. (star effect) You can buy "filters" with straight "etches" to produce this effect. Reflections in film emulsion. - Causes "fuzzy" edges on overexposed areas (street lights at night, etc) Diffraction. - Causes "fuzzy" edges - limits resolution. Ghosting is the only form of "flair" that can be mitigated by quality lens coatings. Regards, Bob But absence of coating also raises the level of light scatter. A lens with multi-coating have less light scatter inside than a lens with single coating. Light scatter is precisely the principal source of flare. ??? Regards, Andre --

This is one reason why Canon has introduced some lenses unmatched by the others. With the EF mount, both the aperture and the AF controls are transferred via flexible wires, so you can place the zoom ring, focusing ring and aperture mechanism anywhere you want within the lens, and you don't have to worry about how you would manage the mechanical coupling with the body (like Pentax and Nikon must do). Plus an electronic aperture control is inherently faster, more precise, and less failure-prone than a mechanical one. > Hope this is the direction they are going to, and the rumoured new > series of lenses planned for the fall announcement would be just > that :-).

Re: buying used 80-320 - strange sound
Hi all! First, I would like to thank everyone for answers. Make sure the zoom is smooth. It might have loosened up a bit with use, but it shouldn't stick at any one point, even slightly. What counts as sticking? If it turns easier at one interval and harder at the other end, is it considered sticking? What could be bad if it sticks? Check to make sure that the aperture blades stop down quickly and are free of oil, and shine a flashlight through the lens to check for fungus and dust, and you should be ok. Aperture seemed to be ok, I tested in all f/stops on my camera. To what extent does dust degrade image quality? There were a tiny piece of dust or two that were visible inside the lens.

Domke bags question
Hi, I sort of like a lot Domke bags (even though they are underinsulated), as they, unlike most other camera bags, have normal, flowing, canvas, contours (unlike most Lowepros/Tamracs, which although very nicely insulated feel like a box at your side). I have used the F2 original for some time (here it's the standard bag in newspaper pool), but it wasn't mine. Now I no longer have access to it, and wanted to buy one (but another model). I am more interested in the smaller models, either the satchel F5, or the "little bit smaller" F6. Anybody here using/knowing the F5 and F6 domkes? Domke is no longer imported into Czechia (perhaps they bankrupted?), but I can get them abroad I think. But I would like to know more. If anybody here tried it, how do you like the F6? And how is the space organised in the F5 satchel? I would be much grateful for some quickndirty digital photos of the bag filled with equipment. Saundersgroup/domke webpage doesn't have any drawings/photos of the inside of it. Thanks! BTW, I like DIY bags, I have several bags that are made from military canvas bags, but sometimes the DIY approach is more money and work and time than buying a good quality bag... Sometimes :) Good light, Frantisek Vlcek

I'm a generally cheerful optimistic person and he captured me not only with accentuated lines and wrinkles, but looking extremely unhappy. Just not fair. It still gives me nightmares.

Well put, I totally agree. Nikon introduced the "manually challenged" F80 in 2000 and the lens it should have been introduced with in 2003 (the 24-120 AFS VR).

Re: *ist and the lens mount.
Actually I would call neither MZ-7, nor MZ-6 an entry level camera, especially if the MZ-60 is also called this way - the former are much >more complicated, as well as the *ist is, and all of them are too >complicated to be put into the same group with the MZ-60. But the *ist serie replaces the MZ-serie. The MZ-60 is far more complicated than my MZ-10, and this was actually replaced by the MZ-7, not the MZ-50 which was a lesser complicated model. If "complicated" means "loaded with features". (I actually finds the MZ-60 to be more complicated to use than a MZ-6). When Minolta released the Dynax 5, they put mid market features (1/4000 shutter, 3 fps, etc.) in a beginners body. Back in the old days - Pentax, and Nikon, didn't have a presence in the low end SLR field. This was covered by EOS 1000 and Dynax 303Si. They were auto-everything zoom compacts in an SLR design. For Pentax, "entry level" meant Z10, Z70 and MZ10. EOS 500 and Nikon F50 was the competition. The MZ-50 was Pentax first attemp in the low end SLR field, and this was actually a Dynax 303 competitor with manual features! I'm happy that Pentax leaves the absolute low-end SLR field and begins a little step higher. And new cameras has more features than before. Look at the MZ-6. It's more advanced than the MZ-5n (1/4000 shutter instead of 1/2000, user programmable functions, more advanced flash system etc.), but it replaced the MZ-7 - not the MZ-5n. And the *ist replaces the MZ-6 (which only lived for a year...). We are still waiting for the MZ-5n and MZ-3 replacement. We have waited many years for this... Two more upcoming models? Yes, according to the managing director of Pentax UK who said last year that Pentax are about to reduce it's filmbased SLR line to consist of only three models. The complete *ist serie will feature... * *ist - entry level (replaces MZ-60, MZ-7 and MZ-6) * (unknown) - mid market (replaces MZ-5n/3) * (unknown) - up market (replaces MZ-S) I remember the rumours of 10 new Pentax cameras being introduced in the 2003, but IMHO actually it will be VERY STRANGE if we see another film >SLR from Pentax in this year. Pentax has officially said that they are going to release 10 new *digital* products this year. (So far, 5 of those has been released) "digital products" can be everything... It doesn't have to be cameras. To my knowledge, they have not said how many filmbased cameras, or products, they will release this year.

Re: buying used 80-320 - strange sound
That sounds normal for that lens. Generally, if it doesn't make you cringe, it's probably okay. Make sure the zoom is smooth. It might have loosened up a bit with use, but it shouldn't stick at any one point, even slightly. Check to make sure that the aperture blades stop down quickly and are free of oil, and shine a flashlight through the lens to check for fungus and dust, and you should be ok. As far as focusing noise goes, doesn't the shop have a brand new one you could compare it with? If not, do you have any other cameras stores in your city you could check with? That would probably be the best way. chris On Wed, 12 Mar 2003, Girts wrote: > Hi! > > I am considering buying an used FA 80-320 from a local shop. > Unfortunately they do not offer any warranty, their policy is: test it > in the shop, if you think that it works, buy it, no refunds.

I am especially interested in how effective is FARE in this models and how are they useable in 35 mm slides scanning??? I would appreciate any samples :-) Thanks! 8000F here. Quite effective. You get 4 settings - none, soft, normal and hard. The "best" setting depends on the size of the dust/scratches. "Soft" will remove only the smallest dust particles, while "hard" will take care of everything including heavy scratches. There is one review on the net that says that it will also soften the whole image. In my experience, this is false. It just affects the areas along the scratches. I found that for reasonable clean film (i.e. that did not suffer some bad treatment or accident), it completely removes the need to manually fix the image in photoshop. I have samples available, but no web site to post them to. If you want, I can send them as e-mail attachments. The only problems I found are that scanning at 2400 dpi is slow, and the film holder is rather flimsy, so you may easily get the film curved and touching the scanner glass, producing newton rings. If you have framed slides, you don't have this problem, but with film strips it is rather annoying. cheers, caveman

This is an easy one, at least in the case of the lens being set to a non-A aperture. The camera doesn't need to know the exact aperture that the lens is set at. All it needs to know is how many stops down from wide open the lens aperture is set to. It meters the amount of light falling on the sensors with the lens wide open. So if it meters 4 times the amount of light falling on the sensor for a correct exposure wide open, and the aperture ring is set for 2 stops closed from wide open, it knows that the exposure is correct. The adapter for screw-mount lenses pushed the aperture coupling ring all the way over to its wide-open position, so the camera meters the light falling on the sensors as is. Thus you get correct stop-down metering with the screw-mount lenses as well. For simple weighted-average metering, this is all you need. -Mat

The Mistery of Fuji 250T
Hi, gang Some days ago, a friend was given a bulk of Fuji 250T film, exp. date unknown. She loaded some rolls, and gave me a couple to test. I did some web research but the only info I found about this film was obscure references to 35mm and 16mm negative movie film. So, knowing only it was tungsten neg film I exposed it and sent it to develop. My dear photofinisher almost kills me. The film went out with a layer of a dark substance wich sticks to the fingers like laser-toner dust. He thought I ruined the developer and filter of his machine, but luckily not. The image is there but covered by this dark layer. He thinks it's another process film, maybe the previous to C41, or something more obscure. Somebody knows what da hell this film is?

Re: Re[4]: Diaphragm actuator precision survey
Come to think of it, I'm not at all sure that the method on Z-1 shows what we want it to. When the lens is _not_ mounted on the camera, the aperture coupler (handle) is in a resting position determined by a spring in the lens. If turned to "A" position, the aperture blades will rest at the smallest available f-stop, eg. f/22. When the lens is mounted, the aperture is forced to open because the handle is pressed down by a lever in the camera. During exposure, this lever lifts up allowing the handle to move exactly enough to rest at the correct aperture (in theory, at least). With pre-selected aperture, the _lens_ decide completely which position the aperture should rest at during exposure. With the "A" setting, the _lever_ in the camera decides. You may have had this sorted out already, but I had to go through that reasoning for my own sake... :-) Now, the _real_ question behind this is: how the heck can the camera know the exact position of any one particular f/stop?

Re: Long lenses handheld?
Really. Do you think all the great wildlife shots in outdoor photographer and other magazines are shot in places other than National parks, from blinds around feeders etc... These guys don't just walk around the woods with huge lenses and 800 asa film hoping to find something that will sit still long enough for them to shoot it. They go to where the pickings are good and work it. I'm not talking about tame animals from a zoo, I'm talking about animals that have grown accustomed to people and allow a fairly close approach. These do not take away from the editorial value of a shot...

Re: KAF3 lens mount already here?
Hi again, Boz, thanks for your excellent summary on DOF preview. However, all you write is in accordance with my idea: A camera capable of DOF preview that has the information that the aperture ring is not in "A" position could in principle stop down the lens by fully releasing the aperture coupler. The lens then would stop down to the selected aperture and the camera could measure the amount of light regardless of what the selected f-number is. If this would only happen while the release button of the camera were pressed half-way down, you would get shutter speed and DOF-information right then, and I wouldn't mind working with such a camera. Arnold Bojidar Dimitrov schrieb: Hi Arnold, I am not able to follow exactly: Let me explain my idea a little more: If a camera (not necessarily the *ist) has no aperture simulator, it can still properly measure the amount of light provided that it does not meter at open aperture. As a camera like the *ist offers e l e c t r o n i c depth-of-field preview, such camera might automatically close the aperture with every lens that is not in "A" position. In this case the camera would not need to know the selected f-number (like it does not know with the K28/f3.5 shift lens). Still, here is a small explanation of how DOF preview works. All lenses with aperture rings have a spring that tries to close down the aperture as much as possible. Moving the aperture coupling of the lens open the aperture. Thus, regardless of which aperture is selected via the aperture ring, the aperture can only move between fully open and the selected aperture. When you mount a lens on a body, as you turn the lens to lock it onto the body, the DOF lever of the body catches the lens aperture coupler and opens up the aperture. Now, when you select a numeric aperture (anything other than "A") and press the DOF button, all that happens is that the aperture coupling is FULLY RELEASED, and the lens closes ONLY DOWN TO THE SELECTED aperture. This "ONLY" is a function of the lens, not the body. This works correctly with K and M lenses (with their non-linear aperture lever) and with A, FA and FA lenses (with their linear lever). Z/PZ cameras do the same also in P and Tv modes, and then the aperture closes down to the smallest lens aperture. This is of course wrong. So MZ/ZX bodies have electronic DOF preview where the lens aperture is released ONLY AS MUCH AS NECESSARY in order to set the f-stop selected by the body. This requires calculating the exact amount that the lever needs to be allowed to move, and thus does not owrk with K and M lenses. The DOF lever is the same one that controls the aperture during exposure, so it must be present on all bodies, even the *ist. And it needs to possess the functionality of selecting any chosen aperture, also on the *ist. Once again, the trouble with the crippled bodies is that they lack another lever. All bodies meter before the exposure, through the lens, using the aperture opening that the lens currently uses. Cameras that have the lever in question know how much the lens will close down during the exposure, and increase the shutter times accordingly. Lenses with manual diaphragms have such a lever, and that lever is at a constant position, thzus saying "the aperture will not close down during exposure". Cameras that do not have this lever do not know how much the aperture will close down, so they assume 0. Thus the overexposure with the MZ-50. Now, the FAJ lenses have only one aperture setting, "A", so they do not need such an indicator of how much the aperture will close during exposure. This is something that the body controls via the other (the DOF) lever. All I'm saying is that if the FAJ lenses do not have this functionality, and if they are a perfect match for the *ist, the *ist may not have the mechanical coupling to read the position of this non-existing lever. Hope this all makes at least a bit sense... Boz

Re: Long lenses handheld?
Paul I certainly would grant you that. The hunt is part of the fun. But after years of photographing wildlife I've come to the conclusion that if you want excellent shots of wild animals and birds you really need to find subjects that are not weary of human beings. The best places to find these subjects are, in the case of birds, around feeders or at least very public areas where they are used to people. In the case of animals, National or provincial parks where they are not hunted and accept humans at relatively close proximity. In these types of areas 300 and 400mm lenses are usually all you need.

I have been simply trying to explain that A)you don't need a 1000mm lens to get excellent shots of birds or animals. B) Using any long lens demands excellent technique. If all you want is record shots of a bird, by all means hand hold a long lens and use 800 ASA film and go out and have fun.

Re: KAF3 lens mount already here?
Hi again, One more thought: Maybe we are all right, and the *ist works with K- and M-lenses, but only with stop-down metering? Let me explain my idea a little more: If a camera (not necessarily the *ist) has no aperture simulator, it can still properly measure the amount of light provided that it does not meter at open aperture. As a camera like the *ist offers e l e c t r o n i c depth-of-field preview, such camera might automatically close the aperture with every lens that is not in "A" position. In this case the camera would not need to know the selected f-number (like it does not know with the K28/f3.5 shift lens). Arnold Boz wrote: I don't think so. Stop-down metering indicates that the lens lacks the mechanical aperture coupling. For example, if the aperture is deep into a tele lens, it is normally too complex to create a mechanical coupling between the aperture and the lens mount. This is why the Pentax shift lens has manual aperture and Canon's has fully automatic --- because they lead the aperture signals with flexible wires to the aperture-control mechanism which sits in front of the tilt-shift mechanism. The problem with the newset Pentax bodies is that the body is not able to read the aperture selected by the lens. It assumes widest aperture, and if you stop down 2 EV, the camera overexposes by 2 EV. I cannot imageine how much weight or money Pentax is saving by this, but it must be significant, since they have at least tree bodies with that mount (MZ/ZX 30, 50, 60).
Re: KAF3 lens mount already here?
Hi Boz, I wrote the above as a SPECULATION, and I ask you to treat it as such. Until this time noone has solid facts, so your guess is as good as mine. Agreed. :-) - the *ist is designed from the ground up to be as small and light as possible, and probably as cheap as posible. I hold it for entirely possible that Pentax removed the aperturecoupling to save weight and size. From the price announced for the *ist (near that of MZ6 and MZ5N) my guess is that there will be one body above the *ist and one body below the *ist, and the latter one will be "as cheap as possible". The only "logical" thought is that with CF 17 = 0 the *ist works like MZ-60 and with CF17 = 1 it works like MZ-50. It is one logical interpretation. The other one is that nowadays a beginner often is not able to work with manual aperture and Pentax cares for such people. - Pentax has released quite a few bodies lately with a crippled mount - Pentax releases lenses without aperture rings (hence without that aperture coupling) together with the *ist, and calls them "perfect match". Well, it is a perfect match, whether the *ist supports lenses without A-setting or not. The latter source also expressed the expectation that FA-J will be limited to the cheapest price segment. The latter source could not say anthing about a new film body or DSLR a month ago. I would say that this source has simply read the press-releases himself, and repeats what he/she has read. I am not fully sure if a person in that position knows the technical operation of the mount as well as you and I do... I believe this source does, and right now this source is presenting the *ist and the *ist D at CeBit, so NOW this source should really know about the K-mount compatibility of *ist and *ist D - unfortunately the statement from this source that I referred to is from February 20th, so it might indeed be based on unreliable information rather than on a hands-on. Also, in the process of piecingtogether the KMP I have come across SO MANY wrong and inconsistent writings by Pentax (for items in production, mind you), that I will not be surprised by anything any more. I agree again. Let's go to CeBit and put an end to all this speculation! You are planning to go. Bring your favorite K-mount lens, and test things out! CeBit is already running... I indeed plan to go at the weekend. However, Heiko Hamann might bring reliable compatibilty news before that Arnold
