Here's two shots with my Porst Color Reflex 50mm f1,7 MC Auto and one with my Presenta 28mm f2,8 MC. The picture of the lake was made with the Presenta, the other two with the Porst lens. The picture of the flower is a 100% crop at f2,8. I love the image quality of the Porst lens and it's colors, i like it even more than the DA 40 Limited. The Porst is very very sharp if it is stepped down to f2,8.
Seems like your Presenta has a purple tint in the picture - same thing happened to me with another no-name 2.8/28 M42 lens, an Auto Revuenon.
I think these are not bad lenses, just the color is off sometime in the blue spectrum.
The Porst might be a Cosina but not sure, congrats on a fine lens.
All the best, Georg

Hi Berend,
Good to see that you and your Exakta zoom have made it over to here to the Off-Brand thread. As you may have noticed, there are pictures from all kinds of lenses here. With any luck, someone might know something more about your lens.
Just picked this lens up yesterday. Don't know anything about the brand other than they made cinema lenses. Girlfriend was nice enough to pose with some of her heirloom tomatoes from her garden.
Wound up unexpectedly with a Carenar 50/1.8 m42 mount Japanese lens. Read that some of these lenses were made in Korea but not this one. Figured what the heck I'll see what it can do. Was actually quite surprised. Good color . a little soft , Might make a decent short portrait lens.
These were all shot wide open. The fungus got a touch of sharpen after crop and resize but the others are right out of the camera except for resize.
Frank /XS400, that Minolta lens looks to have real nice plasticity in the sharp portions as well as smooth out-of-focus background. If that is a Rokkor lens I'd
be guessing it would be really hard to convert it to PK with infinity and manual aperture.
Not so with Yashica(/Contax) lenses, as they feature the same register distance (can be off about 0.5mm sometimes on the short side though). Lenses can be
handheld into PK mount for testing, like you did.
Allright one more from that same Yashica lens. I know Yashica is not exactly an off-brand but hey it has become almost as cheap as them (although there is a reverse tendency with fast manual glass recently). This is from yesterday's Berlin Marathon (the 'real' marathon).
Same lens and cam as above, f/1.4.
This lens is very similar to the Contax/Zeiss 1.4/50. It is not soft wide open and more often than not I have to soften the images - BW conversion is a good way to use it.
My Porst 55mm f1.4 M42 just arrived and I thought i'd try it at arms length (iso200, 1/20th, f1.4 a bit of pp and no crop). Second pic with a touch of surface blur
I reached into my bag yesterday and pulled out the lens that started this "off-brand" thread. After a few shots, I realized again what a jewel my little Auto-Rikenon 50/1.7 actually is.
