  • Macro lenses are optimized for close distances. They usually are not as good as regular 90-105mm lenses for standard shooting, although they usually make quite a good job at it (maybe the corners ...
  • I find your assessment rather severe. The nFD lenses are quite fine, just a little complicated to adapt because of the breech lock. But you can find adapters to avoid this problem (see here ). Othe ...
  • In the 100mm lenses: The Minolta MD 100mm f2.5 is really excellent, it is light and has good coatings. I find its current price quite outrageous, though. Minolta MC 100mm f2.5 is almost identical, ...
  • Definitely the best kind of tools available for this particular problem. I had a dented filter ring on a Canon nFD 200mm f2.8 IF, dented to the point where the integrated lens hood could not even ...
  • Has anyone ever had the chance to test one of these SHIFT adapters ? I am interested into purchasing one for architecture photography... Marc
  • The mount is the same (E-mount), but the 18-105mm is an APS-C lens while your camera uses an FF sensor... So you can use the 18-105mm on your camera in crop mode (which is a shame since it is a ...
  • Just to show the qualities of the Minolta MC 85mm f1.7 wide open : Marc
  • Added 1 photo to their gallery

  • This means that the field curvature would be rather steep in the corners, particularly if the issue is substantial... The corners in APS-C are close to excellent, at least with my copy.
  • Mathieu, I have the C/Y 28mm Distagon and use it my a6000. Of course, it is not an FF sensor, but my results are excellent at almost all apertures in the corners. I therefore have difficulties to ...
  • I am not a Zeiss specialist, but it seems to me that their groups are pretty complete, with Zeiss N, C/Y, G, ZM, Classics, various Hasseblad mounts, Alpa, etc... Marc
  • Go to the official Zeiss site and in the search box, type "historical-lenses". You can then choose the lens from the various groups proposed. Hope this helps, Marc
  • I apologize, most likely an eye to brain connection that snapped ! Marc
  • The 25mm f4 (E.Zuiko Auto-W) is quite capable and very sharp in the centre. The 100mm f3.5 (E.Zuiko Auto-) is an excellent lens too, sharp as needs be. The 50-90mm f3.5 (Zuiko Auto-Zoom) is maybe ...
  • No, I am actually right. Sorry OP for the hijack of your thread ! In any case, OM or Nikon the focus ring turns in a reverse direction against most of the other brands. Marc
  • Ok, I just realised the OM I got the OM wrong. My bad... Marc
  • Group 1 (Minolta MD) : Aperture from largest aperture to smallest -> Left Focus from closest to infinity -> Left Group 2 (Nikon) : Aperture from largest aperture to smallest -> Right Focus from ...
  • Added 4 photos to their gallery

  • You are right in your observation, but I think we are looking at the aperture scale from closed to wide open. If not, then the MD group is also reversed. And my OM 24mm f2.8 is not. In any case, ...
  • Strange, I just had a look at a Nikkor 50mm f1.8 D and both rings run in the same direction. I also checked a SMC Pentax-FA 31mm F1.8 AL Limited, and both run in the same direction. Marc
