  • Stating that exposure is now irrelevant is wrong. If I need to take a picture with my 45mm f1.8 OLY at 1/2000 second and not exceed ISO 1600 I know my lens can do it. But in this screwed up "NEW...

  • How about D-stop or depth of field stop since that is the only place it applies and the rest of us can ignore it as long as you supply the f-stop data.

  • The way to get the same picture is use the same lens at the same aperture and crop the larger format to match. NOTHING else will match exactly because vignetting, distortion, chromatic aberrations...

  • Instead of equivalence try saying that an MFT 25 mm or APS-C 34 mm lens captures the same viewed area as a 50 mm lens on a 35mm camera. The area captured is the same as to final viewed or printed...

  • Unused image is better. Wasted light implies that less light is available for the exposure and a longer exposure would be needed. Same light per square mm is hitting with the different formats.

  • The reason that 120 was better than 135 was magnification. To produce an 8x10 print using 135 you needed more magnification than with 120. Every bit of grain was that much bigger. The same applies...

  • Commented on Olympus PEN E-PM2 Review preview

    The fact is that I looked at a lot of options and have just ordered this camera. Current pricing is $400 with 2 zooms, which is quite a price. Why did I pick this camera?
    1) light weight is...
