One thing I admire about Pentax cameras is the excellent in camera stabiliser system. This allows all those ancient, but excellent Takumar lenses to know be stabilised! Very cool! My Dad bought a classic 55mm f1.8 and a 35mm f3.5 new in 1960 with his Pentax S3, and they are now stabilised on his K7 DSLR! Sure Sony D-SRLs do this too, but the oldest lens you can put on it dates from the late 1980’s.
I really wish Nikon followed this system, as it would have allowed stabilisation on this shot that I took with a 1960’s Nikkor 200mm f4.
