I have a 35mm Pentax with several different lenses. Will these work with new digital cameras?
Thanks for any info. |

short answer, no.
but you could probably get an adapter to mount them on a Canon brand slr as they have a wider mount that allows this. Iuse Nikon lenses on my Canon. Those old pentax lenses are proably not very sharp tho as digital reqires specific lens tolerances that old lenses simply did not possessss. ETA, pentax makes dslr's but not sure if they retained their lens mount. |

Those older film SLR lenses were old tech. Today it is common place to have aspheric lense surfaces(ie parabola-shaped rather than circular lens surfaces). In the old days it was very expensive and require much skill to grind ashperic lens surfaces. Today with computer technology that is a snap. If I remember correctly only Leica had one aspheric lense element in their 50mm f1.2 Summilux lens, and they charged something like $2K in 1970 $$ for the priviledge.

This and the fact my old nikon ed glass I've tested is less sharp and has WAY more color fringing than my cheapest new canon lenses. For instance, my 300 2.8 Nikkor is pretty much useless on Canon mk3 and 5dmk2. I plan to try it on my friends nikon to verify that its not a brand specific thing tho I cant imagine it is. My old manual focus nikkor 50 1.4 that was such an outstanding lens on film is SUPER soft on the DSLRs I've tested. That said, I continue to use old hasselblad CF lenses from the 90s with my digital backs on an ELX and CM and find these lenses as sharp as the new H series and new mamiya glass so who knows. All you can do is test them and see what happens. |
