[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]The 4/3 lenses, sensibly IMHO, sacrifice easily digitally corrected parameters for size and sharpness. Since there is no non-digital (ie film) body on which to mount them this seems a no-brainer to me. Lenses designed for film never had this option, so will be as good as they ever will be immediately. I only shoot raw, and have not noticed a problem with my 20mm f1.7 Panasonic on my Olympus OM-D as displayed in either Lightroom or Aperture. I have not used my 14-140 Panasonic on it yet. I have had super results using a Voigtlander APO 180mm f4 lens on it, but this is a lens designed for film and is superb anyway. >________________________________ > From: A.
