Only really started acquiring vintage lenses recently so currently have the following:
Konica Hexanon AR 28mm f/3.5, 50mm f/1.7 & 135mm f/2.8
Zeiss 35mm f/2.8 Distagon
Asahi Takumar 55mm f/2
I also have the Samyang 12mm f/2
The feel of the Takumar is unbeaten, it’s so smooth! The Zeiss is close but not quite the same, proper heavy German engineering though. The Hexanons are solid but the aperture rings feel clumsy to me, nice feeling focus though and great image quality. My 50mm actually has a short but deep scratch close to the centre of the front element. Only cost £5 so i thought why not, use it as a trial and buy a good one later. Truth is, i honestly can’t see any effect from the scratch at all in final images!
The wishlist would probably include a really special 50mm prime and something around 80-90mm, recommendations?!
I had a Nikon ai-s 80-200 f/4 zoom back in the Canon days, it was amazing for a zoom. I believe the Zeiss Contax Vario-Sonnar 80-200 is a great vintage zoom as well for a similar price to the Nikon.
The Nikon ai-s 20mm performed brilliantly well on my 5D mkii as well.
