Re: Re: 100mm 2.8 Macro vs. 100mm 2.8
Hi Alek, Bokeh is how the areas of the picture that are not in focus are rendered. Whether a lens has good bokeh or not is generally a personal preference. Most people prefer a less distracting background than the pictures that are shown in Fred's link below. I have this same lens and have taken some very nice portraits with it also, but I have also taken some that look just like Fred's examples also. In my experience, with this lens, is that I have to be very careful to choose a non-competing background (no out of focus specular highlights, for sure) for this lens to be usuable. Much more so than any other lens I own. It does make a good landscape/hiking lens when I am more likely using it focused close to infinity.

Re: 100mm 2.8 Macro vs. 100mm 2.8 long
First off, let me say that I own many Pentax lenses including the 15mm, 35mm K 3.5, 28mm K 3.5, 30 mm 2.8, 120mm 2.8, 100mm f4, 200 f2.5mm, 300mmf4A*, 400mm f5.6, just to name a few. But I don't for a minute think that they are far superior to other lenses. It's not about far superiority but the fact that you're buying into a certain optical look. If you ignore it, then it's just fine but why then buy anything with K-mount if you just want the job done? They get the job done and I would wager that no one could tell if the images were shot with or without Pentax lenses any more than you could tell if they were shot with a Nikon or Canon lens. You'll certainly see the difference if you have references. If you put two slides on the light table shot with different lenses you'll see the difference, particularly in color rendition. It's not the lenses that make the shot. They are simply a tool to get the job done. A good lens is a good lens. It isn't that simple. I mean, you can use the same argument about anything like food is food. A car is a car - it's the driver that counts. I'm sure some doesn't see the finer things in lenses but I've learned to appreciate the certain characteristics of (most) Pentax lenses over the years. I cannot understand why using Pentax if not to take advantage of their greatest plusses; the lenses including SMC. So give up the snobbery about Pentax lenses, they're good, we love them but there are other lenses that are just as good and many that are -- dare I say it -- even better. Perhaps, but none of them are third party lenses. Pål - This message is from the Pentax-Discuss Mail List. To unsubscribe, go to http://www.pdml.net and follow the directions.

There's nothing like a blind comparison to bring out the truth. That's not to say I can't distinguish gross differences, or differences in coloration. There's no getting around differences in distortion. And some lenses have more bite.

Get real. I don't know about Canon, but I used to have some AF Nikkors. The colour reproduction from some of them appeared very different from the rather pale SMC lenses. I'd say they were particular great for landscapes. About the bokeh, most of my Pentax lenses don't have good bokeh (imo). But one thing remains true, SMC lenses are far more flare resistance than Nikkors.

Re: Pentax lenses vs. the world? (was Re: 100mm 2.8 Macro vs. 100mm 2.8 long)
I'm sure Pentax is surpassed at times, but I'm surprised at your statements concerning the following comparisons: 1) FA 35/2.0 AL versus Zeiss Jena 35/2.4 (M42) I would bet that resolution will be better for the Pentax, especially in the corners at at any f-stop below f4. I'm not sure in what 'overall' qualities the FA would be inferior to the Zeiss, since it also is extraordinarily contrasty and has surprisingly good bokeh (see Takinami's website). 2) The Pentax F/FA 50/2.8 macro is quite an extraordinary lens - what is the evidence, that the Sigma 50/2.8 is better? 3) Curious: do you have the source for the comparison of the A 135/1.8 and Vivitar Series 1 135/2.3? The A 135/1.8 is not quite as sharp as the A 85/1.4 -but I always thought that this is as sharp as 135mm lenses get. Would be interested to know if the Vivitar is really better (comparing same f-stops of course). Knut PS: Carl Zeiss Jena did produce some quite extraordinary lenses! I do think they are great! But the limitations of non-autodiaphragm screw mounts must be considered as well. At 10:18 14.06.02 -0400, you wrote: I won't even get into which third-party lenses are as good as Pentax; there are too many. But based largely on testimonials, I'd vouch that the following third-party lenses are superior to their Pentax counterparts: Carl Zeiss Jena 20/4 (M42) vs. Pentax 20/4 or 20/2.8 in rectilinearity Carl Zeiss Jena 35/2.4 (M42) vs. any Pentax 35/2 or 2.8 in overall qualities Sigma 50/.28 and 100/2.8 vs. Pentax 50/2.8 and 100/2.8 in sharpness Vivitar Series 1 135/2.3 (M42 or K) vs. any Pentax 135 (even the 135/1.8 PKA) in sharpness Carl Zeiss Jena 180/2.8 Sonnar (latter, autodiaphragm version) and 200/2.8 Sonnar vs. Pentax 200/2.8 Carl Zeiss Jena 300/4 Sonnar Auto Electric (M42) vs. Takumar 300/4 in sharpness, linear correction, and color, and bokeh I've sold off six of my Pentax lenses. Of the 12 lenses that I still have, only three are Pentaxes, and of those, only one below 200 mm. In fairness, I parted with some of these because I had duplicates and felt that I didn't need the Pentax advantage in that focal length.

Re: Pentax lenses vs. the world? (was Re: 100mm 2.8 Macro vs. 100mm 2.8 long)
Knut, You're right about the 35/2 FA; I had forgotten about this autofocus lens. I guess I stand corrected about the Sigma 50 macro being sharper than the Pentax 50/2.8 FA. It sharpness is nothing short of phenomenal. Yoshihiko Takinami writes: This macro is excellent not only for macro work but also for normal use. Better than Sigma EX because the SMC coating is better In my experiences, FA50/2.8 macro seems the *sharpest* with great resolving power and contrast. And David Collett of Oxford University: My top two sharpest primes (from a subjective rather than objective measurement) are the FA50/2.8 macro and my k35/3.5. My A50/1.4 is a pretty close third. In favor of the Sigma, Tanya wrote, Took the most three-dimensional-looking pictures I've ever seen. And there are also numerous superlatives, as I recall, by users at the various lens rating sites. I think Tanya's comment and others I've read left me with the impression that the Sigma was the macro to beat. Now to the 135mm contest: Pentax 135/1.8 vs. Vivitar Series 1 135/2.3. Somehow, all my collected comments on the Pentax have been erased. The comments I've collected about the Vivitar state that it's sharp at all apertures. The Pentax, as I recall, must be stopped down a bit to become truly sharp. Not surprising, since it's about two-thirds stop faster but only 5mm wider in filter size. I was drawing an inference that it can't be sharper than the Vivitar. I also agree with you that the lack of an autodiaphragm can be a big drawback.

As you know I have the SMCPA*135/1.8 and I also had Contax equipment CZ135f2AE and CZ135f2.8MM. You can look up the CZ site and view the superb MTF diagrams for the 135f2.8 (the 135f2 I can send you) however more practically I can tell you that I tested these three lenses under controlled conditions (one film K25, ML, solid tripod, 40x mag etc). I found that the Pentax was better WRT flare resistance and absolute resolution at any aperture, I still own the Pentax lens and the CZ are long gone.

Re: 100mm 2.8 Macro vs. 100mm 2.8
I've read through this thread and there's lots of interesting advice. A few points that you might want to consider: On macro vs non macro lenses: I have an M 100 f2.8 and a Kiron 105mm f2.8 macro (identical to the Vivitar Series 1 100mm f2.5). With the M lens it takes about a 100 degree turn of the lens to move form infinity to 2 meters focus distance. With the Kiron it takes about a 30 degree twist. Yes - you can keep turning the Kiron forever till it gets to 1:1, but for fine adjustment of focus at longer working distances, non macros are better. (And thanks to Valentin Donisia who taught me this - though I argued the point with him at the time!) Also the Kiron is much bigger and much heavier. On Photodo tests: I value these tests and my experience with the lenses I own has been that there is a good correlation between what Photodo says and my personal impression of lens performance. But bear in mind that those tests are all done with the lens set to infinity focus. A lens that is a dog at infinity is probably a dog close up, but if you have two macro lenses that are very good at infinity, you may actually have one that is very good at 1:1 while the other is excellent at 1:1 - and that's something Photodo can't tell you. So I tend to discount Photodo for macro performance because I don't think it really gets into that. On using Pentax lenses: One of the great things about Pentax is that has maintained backwards compatibility better than any other brand. I agree that many Pentax lenses share an aesthetic quality that sets them apart, and that's a strong reason to use them. But I also relish the ability to use older lenses of other brands with my current gear - like the Kiron and some of the older Rikenon lenses that I favor. So I'd argue that the ability to use these off brand, older lenses, and enjoy their unique characteristics, is all part and parcel of the Pentax experience. And I don't have any qualms about using modern third party lenses if they can do the job adequately. On lens performance in general: In terms of sharpness, if you have good technique you'll see the difference between an average lens and a very good lens, if you have excellent technique you will see the difference between a very good and excellent lens, and if you have totally impeccable technique you can see the difference between an excellent and outstanding lens. Once or twice I've managed to produce shots with my A* 200mm macro (outstanding lens) that beat the best I can do with my Kiron 105mm macro (excellent lens) - but all to often I am the limiting factor, or the realities of the shooting situation are the limiting factor. My two cents - if you want to do macro, most of the 100mm macros out there are pretty good - Pentax (of course) but also Vivitar, Kiron, Tokina, Tamron, etc. So if you want to do macro find out what's available, research what's best, and make a decision. When you get to the point where your technique is so good that you reach the limits of your glass - then upgrade. For portraits - hang onto your M 100 f2.8 - the ability to focus more finely / accurately at the working distance of a portrait will be worth it. - MCC At 05:36 PM 6/12/2002 -0400, you wrote: Hey gang...

Filters still screw on and off just fine. The F version, by the way, is identical to the FA version except for cosmetics and the replacement of the focus limit switch with a focus friction control. -- Mark Roberts www.robertstech.com - This message is from the Pentax-Discuss Mail List.

Actually, the Tokina AT-X 90/2.5 is the same as the Vivitar 90/2.5 Macro (1:2). That Vivitar, as has been stated here before, boasted the highest resolution score in Popular Photography's tests for many years. I agree with Mishka entirely on this one. I have several quotes from Nikon users who say the Vivitar/Kiron 105 macro is as sharp as the Nikon; one sold his Nikon, seeing no point in keeping it. In a blind comparison, I doubt the Pentax would consistently be picked over the third-party macros as the winner. But then, I sold my SMC 28/2K and kept my Vivitar 28/1.9; sold my Pentax 50/1.4A and 50/1.2A and kept my Rikenon 50/2. For a photographer like me, who shoots primarily at ISO 400 and higher, ultimate sharpness isn't everything; I'll take sharp enough + great color (Vivitar 28/1.9) or fidelity (Rikenon, which happens to be sharper than the Pentaxes from f/2 to f/4.5).

Re: 100mm 2.8 Macro vs. 100mm 2.8
Mishka, I agree about the resolution. You can't tell much over the internet. Still, I was surprised at how many of my PUG shots were with the macro. I believe that I chose these photos because the slides were special. They were exceptionally sharp, and drew my attention. ...And some of us bought this lens a long time ago, close to your price.

Re: 100mm 2.8 Macro vs. 100mm 2.8
Little bit of a cheap shot here. I'm with Mishka. A Vivitar or Tokina is going to give you just as good results as the Pentax. The feel might be different but the end result is not. The vivitar Series One, Tokina ATX and the Kiron 105mm macros were all excellent lenses in their day and they still are today. Macro lenses are so good that most films don't do them justice. Guys, I love Pentax lenses too but there are plenty of other lenses that are just as good - some even better. Theses other lenses just don't hold their value the way the big name camera lenses do so they are always a better deal, unless you want to sell them.

Re: 100mm 2.8 Macro vs. 100mm 2.8
I'm with you Paul. I have both the Pentax 100mm F4 macro and the Tokina ATX 90 F2.5. Both are excellent lenses but the Tokina gets more use primarily for its speed.

Re: 100mm 2.8 Macro vs. 100mm 2.8
Bob: I think there are lots of reasons photographers gravitate to one or two lenses. It's not necessarily that the lens is better than the other lenses in their arsenal, it's often because they feel comfortable with that lens. A 100 F2.8 is a great lens whether it's a macro or not. I'll bet you like its feel, it's speed and the sharpness of the pictures keep you coming back to it.

Thats OK. The end result is different. The bokeh of the A 100mm f/2.8 is friggin amazing. I had one of those Vivitar 90mm f/2.5 macro lenses that went 1:1 with no extenders. Reputed to be a fine lens. I thought it was, to. Problem was, it had sucky bokeh. So much for art!!. Add to that the feel of the Pentax lens and the A 100mm f/2.8 macro is unbeatable. BTW, Photodo has proven themselves time and again to have worse that useless lens tests. They fall into the sky is pink, I read it on the internet category.
