Hi All,

I have two Super-Tak 35/3.5 lenses, one is the first version (f/22), the other the second version (f/16 without the distance window) as described in the reviews: S-M-C/Super/Auto Takumar 35mm F3.5 Reviews - M42 Screwmount Wide-Angle Primes - Pentax Lens Reviews & Lens Database

It seems that the formula is the same with only minor changes to the barrel, but I'm curious as to why the f/22 setting was removed (I know many of the Taks only go to f/16)?

I need to test them to see if I can see any differences, but all being equal, which one makes the most sense to keep - or doesn't it matter?

Any insights would be most welcome.

Jonh.

I'm guessing no one will know. I'd take a stab that making it go to f22 increased cost in some way. Maybe just some little stupid thing, but somehow that was costing them money.

FWIW, I own the f/16 version and love it.

A consistent smallest aperture across the range makes it a lot easier to set the aperture ring without having to look at it, and in practical terms that's really helpful. Personally I want to be able to set my aperture by feel, and the quickest way to do that is to stop the lens all the way down then count clicks back to the aperture you want. For that reason, I'd much rather have the f/16 versions for all my Taks.

I don't know if that's the actual reason, but it's one that matters to me in terms of real-world use.

It just seems strange to start off with f/22, then limit it to f/16 and then go back to f/22 for later lenses?

Thanks Paul, I'd be happy for a moderator to move it, but don't really want to duplicate the post.

Thanks Dave, that makes complete sense, something to think about while deciding which one to keep.
