I am trying to choose between three 200mm M42 lenses and I was wondering if you guys could help. Also, if you know anything about the actual manufacturers of these lenses, I'd be greatly appreciative. The first lens is a Vivitar 200mm F/3.5 Auto Telephoto #28610273. The second is a Soligor TELE-AUTO 200mm, F3.5 #17100327. The last is a lens marked AUTO-ALPA, Multi-Coated, For ALPA Swiss, 1:3.5 200mm. It's #2540049 and is made in Japan as is the other two. I've found a little bit out about the Vivitar, but not the other two. Thanks in advance for any info you can give me.
You might want to check to see if you find a historical site for Alpa to see if the lens was made to Alpa specs or just rebranded Alpa. Of the other 2, without testing, I would give the nod to the Vivitar, Soligor made some very good lens including rebranded Mirandas, others were real dogs.
I ran across two screwmount 28mm lenses yesterday at a camera dealer, one 28mm had a 55mm front filter thread I believe (Super Tak f2.8) and the other had the standard 49mm filter thread and was smaller, but I can't remember if it was a 2.8 or the 3.5, but it was a Super Tak as well; No SMC noted on either lens. My question is, is if either lens is worthy to buy. The lens with the larger filter thread was $89 and the other $69. I think on refelction now that they were both 2.8's.
Something's not right here. I don't think Pentax made any M42 28s faster than f:3.5. The 28/3.5 SMC is not a bad beast if you run across one.
Pentax made a 28 2.8, I have the 3.5 which I think is very sharp even wide open. Unless you really need the extra speed I would go with the 3.5 just to keep the filter set at 49mm which will match the 35, 50, and 105. But the 55mm filter will match the 24mm, 85mm, 200 and 300mm lens as well.
