Steve, I searched in Russian as well, and the list it bigger. However, I'd like to see the list in English, preferably with experience of using such lenses, rated. Not all lenses worth of wasting money on them, it's cheaper to learn from someone's opinion.
The search is wider in Russian because I can read information about soviet cameras, figuring out what cameras I might looking for on ebay to take lenses off.
However, my first Pentax has to arrive today, and I do have only Helios 44-4 K mount lens for it.
So, I'm pretty new to shop for K-mount lenses with confidence.
