A couple I posted on POTW for this week. M series 50mm f/1.7. Not exactly sure of aperture, I think first shot was at f/2.8, the second at f/5.6. These have been post-processed, LR, saturation and contrast bumps. I dig contrast.

Nice shot. What 50mm f/1.2 is that ? K or A ?
that is the Pentax K version, which is basically the same as the A version.

A real standard lens would be 43mm (diagonal of 24x36mm). This is why for example Pentax and Konica sold cameras with 40mm's on as standard primes, and there is also the 43mm limited and some 45mm lenses out there. If you extend your definition here as fas up as 60mm covering all the 52mm, 55mm, 57mm, 58mm lenses etc, I think you should include a 40-60mm range. Just my oppinion.
I think the thread is about using a prime 50 lens. it doesn't matter what the crop factor equivalent of the lens is.

Two from much maligned Domiplan on short macro ring. I can´t help, but just love those colors. Developed with RawTherapee. No PP, only exposure correction.

Hey Douglas,
looks like the Helios does fare well on the high Mpix K20D, beautiful pics. About the wall photo, why do the white stripes in the middle get wider in the oof-area to the right ? I just can't figure out why.

Thanks George and Rense!
I've been wondering about the cement lines in the OOF as well. It must have something to do with how light is reflected on the cement stripes, and in that region of the picture there is actually a rather strong reflected light (some sand in the cement acts as a lot of small mirror), which cause some sort of odd flare/halo effect in the OOF part of the helio lens. But I'm not sure. I'm going to explore it some more, but it has to be a sunny day with the sun in the right angle.

Rense, mine is a m42, but it is worth having in any case. Go get it if you have a chance. They usually don't cost that much.

Douglas, I allready have two Helios 44M lenses, the 44M, and the 44M-4. Another one is hardly justifiable....

Could be just that it is just very out of focus so the circle of confusion is large. As the cement is quite a bit brighter than the brick the blur spots from it show up over those from the brick making it look like it is getting wider.

Here are a couple of 50 themed photos for my contribution.

Top row left to right:
Ricoh Rokonon 50mm f/2
Petry 50mm f/2
Cosina Cosinon-s 50mm f/2
SMC Pentax A 50mm f/2

Bottom row left to right:
Cosina Cosinon-s 50mm f/2 (in the midddle of being cleaned and repaired)
Super Takumar 55mm f/1.8
Super Takumar 50mm f/1.4
Helios 44M 58mm f/2
Helios 44-2 58mm f/2
Carl Zeiss S Plannar T 60mm f/2.8 macro

Photos taken with yet another Cosina Cosinon-s 50mm f/2. I didn't deliberately get 3 Cosina 50s, just kept getting them with other things and havent got round to selling them on yet.
