It must be nice to be able to spend large sums of money to replace perfectly function lenses for a marginal increase in performance and functionality.

Some people buy new lenses because they want to get the most out of there body's feature set. Others are happy using older lenses that are fine performers, but not up to date feature-wise. Some people buy new lenses like they're at the candy store, others do not. The lens' pre-eminent function is to focus light at the focal plane. All the other features a lens may have are superfluous to this. One does not have to purchase new lenses for a Pentax DSLR, unless they want to. I have not purchased a DA lens and may never do so.

Re: NO FS this Friday?
Just a small comment: My A*135mm 1.8 and FA100mm 2.8 macro are not as good on my dslrs as they are on film. This is not because of the smaller sensor size but because they are optimized for film, not sensors. If Pentax made a FF camera they would have to make new lenses that were optimized for the new, large sensors as the problems the old lenses show on APS sensors would be even more evident on the large ones. DagT Den 8. feb. 2007 kl. 08.31 skrev J. C. O'Connell: these lenses are not really superb or better lenses in terms of overall image quality capability, the DA lenses are actually worse I would venture to say, they just work better on the limited size APS format that's all. If you had a full frame camera that matched what the full frame lenses can do and were designed for, you would reverse which ones you are calling superb and which ones you are calling not performing as well. I dont think its fair or show's much understanding to describe them that way when you are using DA lenses optimized for APS on APS with FF lenses which are optimized for FF but not using them FF and are only using them on APS. Sure there is no Pentax FF DSLR camera at this point but dont mistakenly blame the FF lenses for not perfoming well on APS, blame pentax for the lack of a FF DSLR body that would allow them to outperform the best DA lenses. jco -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Godfrey DiGiorgi Sent: Wednesday, February 07, 2007 9:02 PM To: Pentax-Discuss Mail List Subject: Re: NO FS this Friday?

Re: NO FS this Friday?
If you want to buy a camera and take advantage of half of what you paid for by using old lenses on it, that's your choice. No question that you can do some nice work if you know what you're doing. It's a cost/benefit ratio for me. I'm personally OK with having a little more manual fiddly to deal with, because I know I didn't have to pay thousands of dollars for all of the lenses. As I said before, if you're trying to make money using the camera, there's a whole different set of priorities. But calling someone who wants to take advantage of pattern evaluative metering, linked AE and focus point, MTF prioritized exposure metering, automatic recognition of lens focal length for image stabilization, improved flare control, better image resolution, high speed/accuracy focusing with fine manual control, etc etc, lazy or incompetent is truly bullshit. The only parts of this list that intrinsically affect image quality are improved flare control and better image resolution. The rest are features that provide a greater level of automation. The argument wasn't that these other features are irrelevant or useless, but rather that they have nothing to do with image quality. All these things can add up to improved picture quality when exploited to advantage. For either an amateur or a professional photographer too. There's no doubt that high quality photographs do not *require* all these capabilities, but they can help. Yes they can help, but shouldn't be considered necessary. In particular, WRT the topic of image quality (the ultimate requirement of a lens IMO), old lenses should not be summarily discounted. If one personally values the convenience of more modern features enough to pay for them, great. They shouldn't belittle those who don't. You seem to always want to choose doing things the hardest way, Corey. I don't see any evidence that your choice poses an advantage. One undeniable advantage: cost.

RE: NO FS this Friday?
I'm not calling anybody lazy or incompetent. But I can't help thinking that you Godfrey, who are a skilled photographer, are able to easily work around most the limitations in the older lenses. You are able to focus accurately without AF. You are able to learn your lenses to the point where you know where their peak performance is. You are able to expose properly on your own without fancy metering. I'm not half as skilled as you are. I probably never will be. But I know one thing. It is not the quality of the old lenses I have and use (BTW, it is not many) that is the main limitation in my photography. No, that's me, and me alone. This said. I can see myself gradually building two lens kits. One for everyday photography, built up with mainly new DA lenses. And one, with old lenses for more specialised tasks. Macro is one example. I don't think I need AF and the other sophisticated features for macro work. But that's me. You think in other directions, and I'm totally ok with that.

RE: NO FS this Friday?
NO lenses are as good on DSLR as they are on best film because DSLRS still dont have the resolution of the highest resolution films. This is most likely a limitation of your APS DSLR, not your lenses. I say most likely because your making an assumption that these lenses do not image as good on you DSLR because of digital sensor issues, when its most like due to format size and sensor resolution issues. You would have to wait for a good FF pentax body and compare your 135mm lens to a 90mm DA lens or your 100mm lens to a 66mm DA lens and then compared which is better to be sure which is better wouldnt you? And you last statement is totally backwards/wrong. On a ff sensor, MORE ( more than twice as much ) of the FF lens image is used, so the fixed abberations of the lenses become LESS noticable, not more noticable. (The exception to this would be any lens which actally has sensor related issues vs. film, but I havent seen or heard any hard data on that yet, as we dont have the Pentax FF bodies to make the quick comparisons possible). APS makes normal lens abberations ( not film vs. sensor related stuff ) more noticable because you only use a small portion of the FF lens image on a APS body which is like zooming in on the flaws. jco -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of DagT Sent: Thursday, February 08, 2007 12:36 PM To: Pentax-Discuss Mail List Subject: Re: NO FS this Friday?

William Robb Understood. I'm curious if there are any lens test sites that compare chromatic aberration and other factors of DA lenses with their closest legacy equivalent. I haven't looked but I'd be interested in seeing some data on the subject. The exclusively designed for digital cameras phrase is certainly a marketing term, which leaves me feeling a little sceptical, the same way the 22-bit A/D converter and Prime engine, do. It sounds good but tells me nothing substantial. It doesn't make sense for Pentax (or other mfrs.) to tout backwards lens compatibility and at the same time promote the digitally optimized lenses as being especially desirable or preferrable to all those compatible lenses, which is also a selling feature. It makes a weird sort of marketing sense, but I'd like to see numbers and photos showing exactly how the optics of the newer lenses are *demonstrably* better than the legacy lenses, especially considering the image circle from a legacy lens is from the sweet spot when projected on an APS sized sensor. I'm not arguing they don't have other desirable features. It's not that I'm a disbeliever, it's just that I know it's in a camera/lens company's best interest to sell more lenses.

Not completely, if you dont have the right focal length lens ( proper angle of view ) for a given scene, you cant get full control of the composition. Either you have to use zooms or a bunch of primes if you want to maintain best image quality for a given composition (POV).

JCO wrote: ...but to say these OLD lenses are not as good as DA lenses is really not true. They are DIFFERENT, not better or worse... I can agree with this. It very much depends on shooting conditions, application, aperture, etc. Are the DA lenses *more* demonstrably different/better optically when compared to legacy lenses, than two individual legacy lenses are different from each other (same mfr., cross-mfr.), when used on APS sensors? Pentax wants us to believe both that their DSLRs are capable of producing great results with old lenses, and that they'll produce great results with new DA lenses as well. It gets down to: 1) There's no discernible difference to most people when it comes to looking at standard sized prints or electronically displayed media. It'd be interesting to do a street poll and find out just how many people understand chromatic aberration, noise and sensor size concepts. Want to guess? 2) There are likely trade-offs depending on just how the lens is used between 'digital' and legacy lenses. 3) If you have the money and want the newest whiz bang lens, go for it. Otherwise be happy with what you have or can afford. 4) As Tim said, the skill of the photographer will make a larger difference in photo quality than most lens specifications will.

RE: NO FS this Friday?
How many times do I have to post it? Optimizing for digital and optimizing for format size are two different things, and I dont believe that the differences you are seeing in some of the DA lenses vs FF lenses of the same focal lengths are due to digital optimization, they are due to Format optimization. (DA lenses, designed to cover only 2/3 the angle or 45% of the area of a FF sensor, can be made to perform slightly better ONLY ON THAT SMALL AREA, then a lens which has to cover it all. Digital optimization will become more of an issue for SOME FF lenses when the FF sensor is used, but for now, the limited angle of coverage being used with FF lenses on APS cameras is not bringing digital optimization much into play IMHO. jco -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Thursday, February 08, 2007 1:20 PM To: Pentax-Discuss Mail List Subject: RE: NO FS this Friday?

Difficult to quantify it. But here is one thing I know (and believe). In my other hobby, the difference in the level of sophistication of equipment used is more pronounced than in the case of camera/lens (which is more subtle). But everybody knows that the difference in skill level of people who use it always outplays the difference in equipment used. Nevertheless, people keep spending lots of money for more expensive equipment just to eliminate the factor of perceived difference in equipment. In photography, only those pixel peeper can tell much of difference in decent equipment, be it lens or camera (there certainly are obvious dogs), and become too obsessed with it to the point to forget the joy of appreciating the printed products which is the basic of photography.

RE: NO FS this Friday?
NOPE- I stand by what I stated fully. I say that the some of the FF lenses, even really old ones, will be able to create higher quality images than even the very best DA/APS systems, on a good FF digital K mount body! Yes, some lenses will have issues with perpendicularity (most noticably wide angles or lenses with nodal points close the sensor, but definately not all). Coatings, APO, and other feature sets will not be able to overcome the difference the larger format will make. And some of the older lenses ARE APO and already had excellent coatings anyway. jco -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Cory Papenfuss Sent: Thursday, February 08, 2007 2:14 PM To: Pentax-Discuss Mail List Subject: RE: NO FS this Friday? All those features mentioned below by Godrey DiGiorgi will not make ANY DA/APS lens/format perform as well as a really good FF pentax Lens ( even some of the SMCT screwmounts over 30 years old ) on a good FF camera in terms of sheer image quality. This is what I have been talking about in the thread. With DA/APS you have format limitations that cannot match what is possible with really good, even OLD FF lenses. Of course we all know there is no Pentax FF DSLR camera yet, but to say these OLD lenses are not as good as DA lenses is really not true. They are DIFFERENT, not better or worse, and if just consider them for what they are, LENSES, they can create a better quality IMAGE than DA lenses can once the proper FF body comes along to take full advantage of this capability. jco You're not correct here. There *ARE* featuers of newer lenses that make them better than old ones: - Better coatings - Potential APO in the formulation - Optimized to project the image onto the sensor perpendicularly... not at an angle. Film was much more tolerant of angle of incidence than are sensors. Non-optical ways they're better: - A superset of features can be arguably called a way that it's better.

Or maybe they could spec. a sensor like the Kodak sensor optimized for corner and edge light capture that Leica is using in the M8 without the mistake they made in cover plate/filter stage which is causing so much fun... (It is possible to learn from others mistakes). DagT wrote: Just a small comment: My A*135mm 1.8 and FA100mm 2.8 macro are not as good on my dslrs as they are on film. This is not because of the smaller sensor size but because they are optimized for film, not sensors. If Pentax made a FF camera they would have to make new lenses that were optimized for the new, large sensors as the problems the old lenses show on APS sensors would be even more evident on the large ones. DagT Den 8. feb. 2007 kl. 08.31 skrev J. C. O'Connell: these lenses are not really superb or better lenses in terms of overall image quality capability, the DA lenses are actually worse I would venture to say, they just work better on the limited size APS format that's all. If you had a full frame camera that matched what the full frame lenses can do and were designed for, you would reverse which ones you are calling superb and which ones you are calling not performing as well. I dont think its fair or show's much understanding to describe them that way when you are using DA lenses optimized for APS on APS with FF lenses which are optimized for FF but not using them FF and are only using them on APS. Sure there is no Pentax FF DSLR camera at this point but dont mistakenly blame the FF lenses for not perfoming well on APS, blame pentax for the lack of a FF DSLR body that would allow them to outperform the best DA lenses. jco -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Godfrey DiGiorgi Sent: Wednesday, February 07, 2007 9:02 PM To: Pentax-Discuss Mail List Subject: Re: NO FS this Friday?

I depend upon these tools to produce my work and make my living. I want the best tools that exploit *all* the features of the body which I paid for. When I started with Pentax, I knew little about the line and bought a bunch of older lenses, all in pretty good condition, inexpensively. I used them for a while to sort out what I wanted for the kit, and sold them all at a fair price, which turned out to make a small profit. I took that money and bought the new lenses which I found did the job for my work. I only use five or six lenses total, and mostly just three. I rarely hang on to equipment I don't actually need.

And furthermore, your comments that PENTAX medimum format lenses resolve quite a bit lower than average is horseshit and it only further supports my point that generally 35mm lenses resolve better the MedFormat lenses do.

The increase of sharpness due to not having an auto-aperture? Bullshit. If you're too damn lazy to use manual lenses, just say it. It has nothing to do with picture quality, except in the context of operator error/incompetence/laziness. Bullshit seems to be the word this morning. If you want to buy a camera and take advantage of half of what you paid for by using old lenses on it, that's your choice. No question that you can do some nice work if you know what you're doing. But calling someone who wants to take advantage of pattern evaluative metering, linked AE and focus point, MTF prioritized exposure metering, automatic recognition of lens focal length for image stabilization, improved flare control, better image resolution, high speed/accuracy focusing with fine manual control, etc etc, lazy or incompetent is truly bullshit. All these things can add up to improved picture quality when exploited to advantage. For either an amateur or a professional photographer too. There's no doubt that high quality photographs do not *require* all these capabilities, but they can help. You seem to always want to choose doing things the hardest way, Corey. I don't see any evidence that your choice poses an advantage.

BTW, elimination of jumping mirror dinosaur (using high performance EVF) and sensor shifting AF (similar to what Contax did for their film) would completely change the traditional form factor of SLR. Talking about sensor shift AF, Pentax did XY plane movement for SR, and suppose they can do the same for Z axis movement. Doesn't this solve problems of AF speed, CA and other optical aberrations caused by lens movements? I keep hearing that Oly have been trying to break the mold (legacy) of 35mm SLR in DSLR design.

Re: NO FS this Friday?
In TAv exposure mode, you set your f stop and shutter speed. You then specify a range within which the camera can change ISO. You can select the full range (100 to 1600) or a narrow range. The camera then changes ISO sensitivity as the light varies. Your stop and shutter speed remain constant. I find it wonderful when moving from sun to shade or when the sun is moving in and out of the clouds. It's also great indoors when moving from areas near windows to areas farther away, from brightly lit rooms to dimmer rooms, etc. The uses are many, and it works flawlessly in my experience.

Re: NO FS this Friday?
It's handy for closeup work, too. In the shot I posted recently http://www.jfwaf.com/PAW/PAW.php?name=PAW0703 I wanted f/11 for depth of field, and a shutter speed of 1/25s (still pretty slow for hand-held at 105mm; shake reduction helps). That turned out to require ISO 400, but I didn't have to think about it - I have the auto-ISO range set from 100 to 640. As I shifted viewpoint slightly, looking for just the right shot, the light varied by more than one full stop, but I didn't have to make any adjustments; the camera altered the ISO to compensate.

EAT SHIT WILLIAM ROB, that is your thing isnt it? Every time you are caught with your pants down you avoid simple on topic questions and resort to the stupid personal attackes because you cant handle being exposed for what you are. Why do you continually subject yourself to this kind of flagrant revelation of your own gross stupidity? Your numbers are total bullshit, most (nearly ALL!) medium format lenses are NOWWHERE near those numbers and you know it. you're just trying to cover your own dumb ass. The 45mm is a very wide angle on a LARGER format than the hassy you fool. Anyone with half a brain would not try to compare a 45mm lens on a LARGER format with a 80mm lens on a smaller format, I specifically stated at SAME focal length or same angle of view, that a SMALLER format lens can be made sharper, so you give the complete opposite as an example to prove your point, are you really that stupid or do you think we are all that dumb to not see thru your B.S?.
