like in the old times
My little brother got recently an old 50mm Pentax-M 1:2 lens. While this lens is not known for the best image quality amongst Pentax prime 50mm lenses, it gave me first opportunity to take pictures 'the old way' on my K10D. This is quite nostalgic feeling to have to focus and set aperture manually like in the old '80s with famous soviet camera Zenith. My brother has also some old lenses with M42 mount. I bought adapter allowing me to connect them to my camera and indeed, it works. I find though that 50mm is the most interesting.
This is one of pictures i took with it. It is quite hard to get focus properly, at least for me, but when I succeed, the satisfaction is much more rewarding than when I use 'intelligent' lens.
By the way, winter in Poland looks beautiful, provided you have heating (it can be -20 C here or less) :).
