Even optically they might be similar, at least one of those Vivitar lenses has 13/10 lens construction like Pentax. They have the same (I think at least) the macro setting available only the the 70mm setting. They have the same push-pull zooming mechanism, with (in my opinion at least) reversed zoom position (longest is closest).

No, I do not have any evidence, just those lenses look so similar. Vivitar Series 1 70-210 M M 1:3.5 Macro Focusing Zoo perfect condition Product information Package Dimensions 8.3 x 5.7 x 5.5 inches Item Weight 8.
To sum up, I expect the Vivitar to perform respectably on Digital but would rather use the Pentax A 70-210. I couldn't say how they would compare in pixel peeping. On high-accutance slide film, the three lenses were pretty much the same in terms of sharpness. On slide film, the Pentax offered better highlight detail than the other two. The Pentax is extremely good in that regard. Comments All photos are copyrighted and may not be used without permission from the photographer. While very good in terms of sharpness, the Viviitar had significantly poorer flare resistance than the other two.

I have a fairly clear memory of testing an A 70-210 versus a first version Vivitar and a first generation Nkon 80-200/2.8 in the late 80s. It is a completely different lens from the Vivitar. I recently picked up the Vivitar 70-210 series 1, version 1 (version 3 would be great for this too) in Minolta MD mount, and then shortly thereafter the. The Pentax A 70-210 was released in 1984. At the time it was major breakthrough as a lens that was capable of decent macro as well as overall very good image quality. The Vivitar 70-210 was introduced in the 70s- I think around 1975 or 76. To refer to it as "a clone" is stretching things a long way. The Kiron and Tokina versions (variants 1 and 2) have constant aperture (f/3.5) but look nothing like the Pentax-A. The Pentax has a constant aperture (f/4) across the zoom range the the Komine-made Vivitar which you say "looks identical" doesn't (it's variable f/2.8 - f/4) none of the other Vivitar variants look in the least like the Pentax-A. The 4th & 5th editions are nothing to seriously consider, so we will concentrate on the first three editions, which are the good one's. However, for the sake of discussion, we will deal with the first five. Are you aware of the Viv S-1 28-90 or the Kiron 28-85? As for Kiron glass, well that's another discussion.Peter, I wonder if you have any evidence (apart from "it looks the same") to support your assertion that these two lenses share anything beyond the zoom range? There are numerous Series 1, 70-210 lenses. If you have anymore questions about the Vivitar or Kiron lenses, or want more detailed information on a particular lens, please don't hesitate to ask. I have and use all three of the first editions, and can highly recommend any one of them. Personally, I recommend the second or third edition of the line. I really like this lens, and in time may become my favorite. Any of the first three editions will give you professional-publishable images. Can you see a discernible difference in slides taken with either one of them? No! Don't get caught up in bench tests. It has 1:2.5 life size macro from 100-210mm's, with a working distance of about two feet. It is a 2.8-4 variable aperture lens, and the sharpest of the bunch. The third edition was made by Komine, and like the first two, is very well built. However, not a true macro, 1:4 life size. I really like it because of the fixed 3.5 aperture which is nice for focusing in dim light and long range flash work. Like many Vivitar lenses, it was made for Vivitar by fourth parties, and its design varied over the years. It too, is a fixed 3.5 aperture, but smaller, lighter and sharper. The Vivitar 70-210mm Series 1 is the classic of classics of third-party lenses. The second edition (my personal favorite) was built by Tokina, per, Vivitars specs.
It was the first zoom, designed with the aid of computers, that truly rivaled the OEM lenses of the time.
#VIVITAR 70 210 SERIES 1 PROFESSIONAL#
(67mm filter) It is a professional caliber lens, with a 1:2 macro feature built into it. The first edition was designed by Vivitar (Ellis Betensky had a hand in it) and built by Kiron. It is much easier to design and build a quality variable aperture lens. Due to the fact that the third one is a variable aperture lens, (2.8-4) it will be somewhat sharper than a fixed aperture lenses.

The 4th & 5th editions are also 2.8-4 variable aperture model's, but lacking in construction quality (Cosina built). There are numerous Series 1, 70-210 lenses.
