  • I am often using adapted Nikon lenses on my Olympus. It is very important to enter the focal length if the anti-shaking function is on, but it requires many steps - too many steps. Is there some ...
  • I have very similar equipment: LX100, GM5 and E-M10-II. I could write 10 pages of plus and minus for these 3 cameras, but the bottom line is this: 95% of the time, I am using the Olympus E-M10-II ...
  • Correct me if I am wrong, but I am pretty sure that, say, a 100mm lens, will have exactly the same depth of field on a FF, APS-C and MFT camera at, say, f2.8..... The dof will increase with ...
  • On my Olympus E-M10-II, I can select different magnifications for the EVF, I am using typically 5x to manual focus with adapted lenses, and if not 'state-of-the-art', this EVF is adequate. As for ...
  • Replied in Enlarger lenses
    Around 1980, the best of the best were made by Rodenstock, closely followed ex-aequo by Schneider and Nikon.
  • Replied in Distortion
    I read a test that showed 5.3% of distortion for this lens... Personally, for me it kills it. Not acceptable, even cheap zooms are doing a lot better.
  • I forgot: this focal (50mm > 100mm on M43) will often be used for portraits. If it will be your main usage of one of these lenses, the Olympus OM 50/1.8 is a strong option, being really good at ...
  • This time, I compared very carefully the resolution and contrast, on a brick wall at 60', the following lenses: Nikon AIs 50/1.4, Olympus OM ('Japan') 50/1.8, Minolta MD (latest version) 50/1.7, ...
  • Genuine Schneider lenses are outstanding. I used three of them: - A 'Leica' R 28/2.8PC, made by Schneider. Incredibly good, even without using the shift capability, the best 28mm I ever used; - ...
  • - Your test is at a very close distance, doesn't tell you anything about the quality of this lens at normal shooting distances. - The distortion seems to be huge, unacceptable to me. Yes, it can be ...
  • You could use an Olympus Stylus 1s instead. Or a Fuji X30. This sensor is so small that you can have a compact with a huge, large aperture zoom covering 99% of a photographer needs... Also, maybe I ...
  • Even with 'no glass' extension tubes, the aberrations, like field curvature and distortion for example, change with the distance of the subject. This lens, like other 1:2 Macro lenses, is probably ...
  • It is bizarre... I used this lens during many years on a Pentax K10D, and later on a K30, and loved the results. I recently tested it (brick wall 60 ft away) on my new K70, and Olympus OM-D ...
  • Replied in Leica R
    I had many Leica R lenses, I sold more than half of them a long time ago... I bought an adapter M43-Leica R, and tried the R 28/2.8 (new version), R 50/2 and R 90/2.8, the ones I kept for their ...
  • FF sensors are necessary mostly for professional studio or landscape photographers, Serious amateurs and News photographers can use 1", M43 or APS-C cameras. - The industry should be able, though, ...
  • Thanks for all these info, they confirm what I suspected, MFT is far from optimal to use old Manual Focus lenses... I will look into Fujifilm cameras, but will sale stuff on Ebay first, my budget ...
  • Thanks for all these info. Will check these focal reducers,
  • Thanks for the suggestion. I am a little nervous about these focal reducers: they are expensive, and do they give sharp results? Did you try some of them? Which ones are good?
  • Replied in Enlarger lens?
    You made me think: I have a Schneider 50/2.8 on an enlarger in a closet, that I didn't use for 20 years! Can it be used on MFT camera? How would you focus?
  • I am discovering the wonderful world of adapters, and testing / using all these lenses I dreamed about when I was a teenager... I was using mostly Pentax lenses and some Leica lenses (I made money ...
