28mm A lenses?

GeneV · 01-11-2015, 07:01 AM

I have both versions of the M 2.8, and they both perform admirably. I'm really not sure it was worth getting the one that is essentially an A lens without the contacts.

I have the Kiron 28/2 with an A setting. I probably use it most of all the manual focus 28mm because it has the A contacts and the fast aperture. Performance is quite good, Since getting the FA31, all the 28mm lenses are collecting more dust.

The A28/2.0 is high on list of LBA targets, but it is devilish rare. If anyone finds one, but doesn't want to pay the market price, drop me a pm....

Hi

I have that lens. What is so special about it? I havn't tried it to much.

What alternatives around this focal length (A lens type) should be taken into account from third-party lenses?

there are a bunch of good 28mm legacy primes out there, it's a much more forgiving focal length than 24mm.

you really don't need to leave the pentax stable to find a good 28mm prime, tho, look at these resolution tests:

28mm is a nice FL on APS-C. You can pick up Pentax/Sigma 28mm f/2.8 A lenses pretty cheap - ~$30-$60

This is what I picked up for $30 at the Pasadena camera show.

I was looking for a fast 28mm lens, and went with the Kiron 28mm f/2 MC, and even due I use it rarely, but I can't part with it. it's sharp in the center from wide open! but the contrast is better from f/2.4
And you can find it in PKA mount too!

I'll let you know if I find any at the Pasadena show on Sunday.
There are a lot of 50mm and 28mm there, and one group has a list of all Pentax M42 (even a 300mm M42).
