Re: DA* 60-250 to C.R.I.S.
I really like the SDM lenses, although I wish they were more reliable. My DA* 60-250 dis over 20,000 frames before it failed. Of course it should never fail at that price, but it has served me well and helped earn a good amount of money.

I don't subscribe to the use it or lose it theory. However, I also have three SDM lenses and I've had two motor failures, both in the 50-135. The first was under warranty still, the 2nd is two years later and I'll have to pay to fix it. I regard it as pretty terrible. The same type of failure *twice* in four years? Sheesh.

RE: DA* 60-250 to C.R.I.S.
you could also buy a 200 or 250mm F4 prime as a backup to fill the gap between 135 and 400. Pentax 200mm F4 prime are cheap. I think vivitar made a 250mm F4.5 which is also cheap. If you must have a zoom there was a tokina at-x 100-300 F4 that is superb.

Re: DA* 60-250 to C.R.I.S.
What Bruce said. Forty years ago I could manual focus any lens, every time. I could even pull focus on a car moving toward me. But eyes wear out faster than old manual lenses. I had a heck of a time focusing the 400 yesterday, particularly when working from my knees with the camera on a low tripod. Manual focus is largely in my past.

RE: DA* 60-250 to C.R.I.S.
I think the A400/f5.6 is an exception, because its so slow. I even have trouble with mine. Most of my MF SMCK lenses are shorter and faster like F2.8 or faster, making them easy to MF. Having a split image screen doesnt hurt either. I just dont like AF, it misses too much or hunts too long ruining the decisive moment. I will concede AF is better for fast action where its impossible to keep up manually focusing, but thats a special case. - J.C.O'Connell hifis...@gate.net - -Original Message- From: pdml-boun...@pdml.net [mailto:pdml-boun...@pdml.net] On Behalf Of Paul Stenquist Sent: Wednesday, September 26, 2012 8:56 PM To: Pentax-Discuss Mail List Subject: Re: DA* 60-250 to C.R.I.S.

Re: DA* 60-250 to C.R.I.S.
Autofocus is fine for shooting cars off a tripod, which is my most critical work. It's not hard to lock onto a headlight or bumper edge. I shot a group of executive portraits for a consulting company last week and used the DA( 50-135, focusing on the close eye with a single point. Almost all were critically sharp at full magnification. Missed maybe 2 or 3 out of about 100 frames. i think you're correct about the 400/5.6 being particularly difficult to focus with the small wide-open stop. I'll have to dig out my K series 85/1.8 and shoot some pics of Grace in the studio. I'll see if my tired old right eye can still manage. I do get enough diopter correction to get a sharp focusing screen, but I'm not sure that's all that's involved. Paul On Sep 26, 2012, at 9:05 PM, J.C. O'Connell hifis...@gate.net wrote: I think the A400/f5.6 is an exception, because its so slow. I even have trouble with mine.

Re: DA* 60-250 focus tests
The autofocus is very close, so I don't think I'll adjust it. It appeared to be right on at 60mm and registered a wee bit of front focus at 250mm. Congratulations on getting the lens. Pentax's recommendation for AF testing with a zoom lens is to do it at an intermediate focal length. But it sounds like you'll find it okay. Reports on this lens so far look favorable.

RE: DA* 60-250 focus tests
ideally, really good zoom lenses dont change focus when zoomed in or out. I guess this is a separate issue from AF focus errors vs focal length. I still dont understand why these pentax cameras dont auto focus all the lenses the same when the af sensing is in the body. The AF bodies need calibration/tweeking to every AF lens?

Re: DA* 60-250 arrived
Unfortunately I have already deleted those files (as I do with most of my technical shots). But I have wrote down some observations: 60mm - DA*60-250 is sharper at f/4. At f/8 two lenses are practically the same in sharpness, but I like the bokeh of 60-250 a bit more. 90mm - no significant difference in sharpness between the lenses. For me, longer zoom still has better bokeh. 135mm - at f/4 DA*50-135 seems to be a bit sharper at corners, but I can't find any difference at center of frames. At smaller apertures DA*60-250 jpegs show slightly more contrast than DA50-135 ones. I really like the internal zoom mechanism and relative compactness of 50-135. However, I can not use this lens with film body (Z-1p). Also, the focal range of DA*60-250 seems more practical and f/2.8 aperture have never been my first priority. For ULTIMATE quality I have and use 50, 70, 135 and 300mm Pentax primes (and 90mm Tamron macro). So it seems that although I have no real urge to sell DA*50-135, there's also no good reason to keep both zooms.

Re: DA* 60-250 arrived
I definitely plan on keeping both. The extra stop of the DA* 50-135 is needed for indoor work, like concerts and wedding ceremonies. Plus it's relative compact size makes it a good walkaround lens. On the other hand, I'm thrilled with the DA* 60-250 thus far. I'll use it for outdoor events, outdoor wedding ceremonies and a whole range of other things. Paul On May 14, 2009, at 6:11 PM, Margus Männik wrote: Unfortunately I have already deleted those files (as I do with most of my technical shots). But I have wrote down some observations: 60mm - DA*60-250 is sharper at f/4. At f/8 two lenses are practically the same in sharpness, but I like the bokeh of 60-250 a bit more. 90mm - no significant difference in sharpness between the lenses. For me, longer zoom still has better bokeh. 135mm - at f/4 DA*50-135 seems to be a bit sharper at corners, but I can't find any difference at center of frames. At smaller apertures DA*60-250 jpegs show slightly more contrast than DA50-135 ones. I really like the internal zoom mechanism and relative compactness of 50-135. However, I can not use this lens with film body (Z-1p). Also, the focal range of DA*60-250 seems more practical and f/2.8 aperture have never been my first priority. For ULTIMATE quality I have and use 50, 70, 135 and 300mm Pentax primes (and 90mm Tamron macro). So it seems that although I have no real urge to sell DA*50-135, there's also no good reason to keep both zooms.

Re: DA* 60-250 at BH
Gross defects, probably. Marginal changes in sharpness, with this image, not in a million years. The trees appear to be in a line closest to the camera on the right and furthest away on the left. Those in the middle are in focus, the rest are not, as I would expect at f4. The leaves are probably moving in the wind, adding to the impression of blurriness. The negative has also been scanned, adding even more defects into the mixture. P. J. Alling p_all...@hotmail.com wrote: You're right it is just one web image.

I read somewhere that the reason for the really long delay on this lens was caused by a complete redesign of the optical formula to allow for full frame coverage. The 55/1.4 also covers the 24x36 format. I'm just guessing here, but I expect Pentax knows that whether they go willingly or kicking and screaming, full frame is the future. William Robb I doubt it. I think the K7 may well be the last DSLR from Pentax; certainly the last high-end model (think PZ-1p/MZ-S, which marked the end of technological advancement on the PEntax film bodies). The future is in cameras with far less mechanical parts - definitely no mirror box and moving mirror, and probably no mechanical shutter either. Mechanical assemblies with many moving parts are expensive to manufacture, and tricky to align correctly. The 4/3 and micro 4/3 cameras have shown that you don't even need a sensor as large as 16x24mm to produce image quality more than good enough for the upper end of the mass market, which is where Pentax target their products. By going to a micro 4/3 camera complete with EVF Pentax will be able to achieve the smaller, lighter goal that Hoya seem to have in mind.

Re: DA* 60-250 at BH
Some lenses that are optimized for APS will still cover the full frame, particularly those of longer focal length. Pentax has indicated that all the DA* lenses are intended for digital APS use. See Ned Brunell's recent column ad the listing for the DA* 60-250 on the Pentax USA website. The fact that you can use a lens as a hammer doesn't make it a good hammer.

RE: DA* 60-250 at BH
This is the confusing part, if these lenses cover full frame and at a quality level standard and optimized for digital, they should have designation as such and could be used on ff film or ALL digital. Its really dumb for pentax to have a series of lenses than are designed for different formats but designated the same. regard using lens like hammer I dont understand that. the A70-210 is considerably smaller and lighter than the 60-250 even though it covers FF. As for its image quality, I am not assuming anything, thats why I would like to see good scientific comparison testing on APS between A70-210 and DA60-250 and ditto for the SMCK55/1.8-2.0 and the DA55/1.4. What I would like to see is all cases of any new pentax lens that has a former similar version be tested/compared to the former roughly similar versions. Regardless of formats, costs, sizes, etc. i.e. say you want to use a Pentax APS SLR, why not compare a given new DA lens to every similar Pentax lens that would fit like K,M,A,F,FA versions that are similar in focal length range and speed. It would be interesting because there not a lot of good info on the vintage lenses being used on APS. I find some are fantastic on digital and some arent, but only by personal usage. We need a better collective database on such matters.

RE: DA* 60-250 at BH
Um no, there are lots of lenses without any visibly noticable light falloff on the edges of the intended format, mostly long ones. I would not agree with the statement that all lenses could be considered optimized for APS-C just because they dont have as much light falloff or corner sharpness falloff on APS-C as FF. There are other factors like overall sharpness and flare control situations too, not to mention that with Pentax, at this time, digital recording is tied to AS-C format so if there are optical considerations for digital sensors, most FF lenses would NOT be optimized for APS-C(digital sensored).

Re: DA* 60-250 at BH
Unfortunately DA*50-135 doesn't fit FF. Wide open you can see dark corners clearly at 50mm, vignette achieves the maximum at 70mm and then reduces to mild falloff after 90mm (but you can still see it at 135mm).

Re: DA* 60-250 at BH
Absolutely, and this is probably why it shows so good results right from wide open (at APS-C bodies). One more interesting fact. As you may know, there is a MTF sub-program at K10D and K20D (actually the setting have been there since FA lenses and Z/PZ bodies appeared - for example Z-1p has it). In this mode camera tries to use the sweetest aperture range of attached lens. I do use it quite often as my normal shooting mode and simply adjust aperture if I don't like what camera likes (Hyper Program). Usually it means that camera is trying to keep the aperture somewhere between f/5.6... f/8 or so, but you never see any lens used wide open - even if there's no light at all. Now, when I got DA*60-250 I was really surprised to notice, that camera quite often decided to use f/4. I made a simple test and found out, that in low(er) light situations (indoor at sunny day is enough) K20D MTF program really chooses f/4 from 60-135mm and switches to f/5...f/5.6 at longer focal lengths. Z-1p preferred f/5.6 through the whole zoom range. Isn't it a clear message from Pentax optical engineers - the lens is really good enough to be used (at APS-C bodies) wide open?

RE: DA* 60-250 at BH
If I get the time and remember, I will take my A70-210 out to Boca Inlet and get some seascapes with it and some similar primes and zooms for comparison. I aint be able to shoot the DA60-250 because theres no way Im buying that at $1350 now. From what I recall my Tamron SP 80-200/2.8 is at the top of the heap, followed closely by the Tokina AT-X 80-200 which I also have. Now that I think of it, there must have been a lot of good telezooms produced over the years if you count from 1970's to date. Even the original 85-210 SMCK F4.5 zoom is pretty damn good IQ, just slow, physically long and wont focus close at all. FWIW, I think I have these zooms still: smcA 70-210/ F4.0 smck 85-210/ F4.5 smck 85-210/ F3.5 tamron sp 80-200/2.8 tokina at-x 80-200/ F2.8 tokina at-x 100-300/ F4 smcm 80-200/f4.5 plus another dozen or more primes in that range.

Maybe it's the subject matter or just my eyes, but I seem to detect a bit of image degradation at the edges and corners. Not a lot different than the FA 28-200mm.

Re: DA* 60-250 at BH
I've inspected also my other DA*60-250 on film frames. To get maximum performance, I would use f/5.6 or smaller. I lab-printed (direct film-to-paper copies) couple of frames to A3 size (30x40cm) and those look quite good. I just dont' like AGFA colors - too yellowish and redish for me. I'm much more like Fuji-man :) For this particular shot I should choose the better scene - trees at right edge are much closer than the ones at center and left. It creates the illusion of right edge being softer. Sorry for that, I wanted to finish the roll fast and get back to sickbed (this damn virus still tortures me)... BR, Margus P. J.

While getting rid of as many parts as possible is a good idea (better reliability, lower cost), there needs to be some market differentiation. I suspect that APS-C, DSLR performance, K mount lenses, weather sealing, and optical viewfinders are all part of the intended market differentiation for Pentax. Note that Panasonic is a consumer electronics company; Pentax (and Hoya) are optical companies. They don't want to wander out of the area of their strengths into those of the competition, which is what moving to an EVF would do. Also (and more speculatively) note that there's been a very large RD effort put into optical switching over the last thirty years. It's quite possible that the mirror box replacement will be some sort of electronically switched nanoscale coating. (All sorts of these have been demonstrated in the lab, starting around 1990.) Pragmatically, if that thing on top of the K-7 is an EVF, you're likely right. If it's a full-view, full magnification pentaprism, I'm going to suggest that it means I'm right, at least as far as optical viewfinder being included in the intended market differentiation strategy goes. -- Graydon -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.

the untold problem with doing hd video with still camera lenses is that the zoom lenses you can get are not well suited for video use, no power zoom, no proportional power zoom.

Personally I don't care, but I know that I'm not the target customer. I'm not sure this is the case. Clearly people want a combined still and video camera -- since this is what their phone does, and everything that isn't a phone camera is a niche camera -- but this may not overlap with the people wanting the best possible stills for the money. So I suspect it's at least as likely that the camera market will split into art cameras -- DSLRs and medium format, best-possible-stills -- and video cameras with a decent stills capability than that it will collapse into exclusively stills-and-video cameras. The tradeoffs are significantly different for the hardware design as well as the users. The capability is already showing up in consumer cameras, although as yet it isn't always fully integrated (no auto-focus adjustments, say). But once you have live view and 60fps video, you've already got an EVF. Only if you've got the hardware to record video and play video at the same time. This isn't really a given. Nor are the zoom-to-check-focus, etc. functions of an EVF obviously present in the usual back-of-camera LCD. If that means venturing into the strengths of Panasonic, so be it; the alternative is to be left on the sidelines. And, in any case, there's still a lot of space in front of the sensor for an optics company to showcase their capabilities. Not really; once you've got the massive data loss involved in the EVF sitting there, there's a bunch of stuff you just can't do, starting with seeing what you're looking at through the lens or seeing it at the actual level of brightness. I'd rather give up photography than go back to an EVF. If there are enough people who think that way, there's a very comfortable niche available. -- Graydon -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.

I don't think electronic shutter will replace soon mechanical ones. Nikon did use electronic shutter. It increased flash sync easily but reliability was difficult to obtain it seems.

From information absorbed by my little noggin way back when, I am now under the impression that optimized for aps-c meant, among other things, that it was an effort to make the light rays more parallel as they struck the sensor to prevent the color fringing we see in our digital images. Supposedly caused by the angle of incidence of light rays to the sensor pixels in the corners and periphery of said sensor, which allowed the light ray to strike more than one pixel under such circumstances.

Re: DA* 60-250 at BH
I was thinking about some DA longish lens to solve a problem much like yours - but with the need to cover at least marginally a 35mm frame since I'll be going to places a 35mm camera is an interesting backup. But that price is out of my budget for the time being. I'd like to think that may change in the future. For the kind of result I'll be turning out I'll be shopping for a third party FF lens as soon as the deal is signed. Funny thing is I could get a very interesting cash figure for the gear - mixing Canon 35mm and digital cameras. Sometimes using Pentax is more than just business. LF Paul Stenquist escreveu: I use zooms for event coverage. I shoot with two cameras. One gets the wide: the DA* 16-50, the other gets a longer lens. For that I've been using the DA* 50-135. But I've found that I can't always get close enough for the 135 FOV. So I'd like to have better reach on my second camera. The 60-250 fills the bill perfectly. I wouldn't even consider a manual focus lens for this role. It's bang, bang, shoot them dead work. Fast is good. And my eyes are old. What's more, I've found that the DA* lenses deliver better image quality on my Pentax digitals than lenses that were designed for full-frame cameras. Yes, Pentax may some day introduced a larger sensor camera. But I live in the here and now, and I have to get the job done with the equipment that's available.

Sure, weather sealing, greater zoom range, and AF definately add value to the DA lens but it would NOT add over a $1200 value to a $139 lens to ME if the image quality was only the same in the DA lens. To each his own. There is also the possiblility that the DA lens wont cover FF digital in the future as well as the A lens does. Thats a possible liability, not a plus for the DA lens. Bottom line is that I wouldnt pay the $1200 premium if the A70-210 was just as good optically for the DA60-250. The $1200 saved could buy to many other MUCH more valuable features to me like more good lenses and good DSLR bodies. To some, the extra things the DA60-250 does would be worth that premium, but not for me. We are talking 10 times the price or approx $1200 more for the DA lens vs the A lens mentioned.

Personally I don't care, but I know that I'm not the target customer. The capability is already showing up in consumer cameras, although as yet it isn't always fully integrated (no auto-focus adjustments, say). But once you have live view and 60fps video, you've already got an EVF. If that means venturing into the strengths of Panasonic, so be it; the alternative is to be left on the sidelines. And, in any case, there's still a lot of space in front of the sensor for an optics company to showcase their capabilities. -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.

Well, we have now a high speed sync, up to of 1/6000 isn't it? The 1/180 is only needed for older flashes. Well, high-speed flash sync only works if you are prepared to accept a flash with significantly less power. At 1/6000 (and a 1/180 sync speed) the flash has to fire 32 times, once for each strip of the total frame. That means you can't use more than 1/32 of the total light output on any part of the exposure. Seems to work just fine to overpower the full sun, anyway. I've used HSS with the K20D and 540FGZ flash to shoot flowers in full sun and still end up with a dark background and the flower lit only (mainly) by the gel'ed flash. From 1/1000 up to 1/4000 sec. (I don't believe the K20 goes to 1/6000.) I know the flash was working hard because of the additional recovery time and that low whine you get when you pop the flash near full power. -bmw -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.

You're right. And even those without a prior investment may go for a Pentax MF digital, since there are numerous excellent used lenses available at very reasonable prices. The market isn't huge, but it's big enough to be profitable. You can be sure that Hoya has given this a lot of careful thought.

Re: DA* 60-250 at BH
My prediction: Whatever the last model DSLR produced by Pentax is, it will be the last high end camera I'm likely to buy from them. The 14mp sensor is already higher resolution than I could reasonably achieve with 35mm film and its high ISO performance is better than I could have dreamed of just a few years ago. So I won't be funding the RD on a good EVF. In fact if the K7D is the last Pentaprism camera that Pentax makes, unless it's an order of magnitude better than the K20d, the K20D is likely to be the last DSLR I buy, well Buy New at least.

Apparently the Lumix DMC G1 is supposed to be a good one, and it gave me a headache in less than half a minute of using it. I'll give you two daring predictions for the future: 1 - EVF's *will* eventually compete with mirror/prism viewfinders in terms of image quality. 2 - The transition from mirror/prism to EVF will take place *before* the abovementioned transition (and we users will suffer through lower quality electronic viewfinders while financing the RD that eventually results in the high quality EVF). -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions. -- Always read something that will make you look good if you die in the middle of it. -- P.

well you cant see resolution in a small photo but you can see color saturation and contrast and flare or lack thereof. That site reduces everything to 1024 pixels wide so I cant make it any bigger there. I can do a crop at higher mag, maybe I'll add that. FWIW, the second photo of the silver car had so much contrast coming off the scene/lens that it strongly pegged both the black and white ends of the histogram in RAW!
