If more is better, lets compare it with a 645D. It's a bigger sensor with more resolution, therefore its better. If you have your 4/3 with you because you can carry it, but you left your 645D at home, then it's better. If you can afford to buy a 4/3, but you can't afford to buy a 645D, then it's better than not shooting with gear you don't have. The same benefits for larger sensors held for larger film, but how many people shot 35mm rather than medium format, or medium format rather than 4x5 or 8x10? There tends to be a feeling that if more is better, then too much is just enough, when in reality for every design there is an optimum. Three years ago I was just biding my time until I could afford a full frame camera, now I realize that today's APS sensors perform as well as the full frame sensors of three years ago. If I needed the extra stop or two, I could trade my Kx and lenses in on a D700, at probably four times the price. Remember that full frame lenses cost more for the same performance as to APS lenses, because they have to cover a bigger sensor. The same physics holds true APS vs 4/3. Micro 4/3, the camera that brought up this discussion is EVIL, not an optical DSLR. If you can see the display in a dark room because it supplies its own light, but you can't see through an optical viewfinder to frame, much less to focus, then the electronic viewfinder is better. Micro 4/3 does not have a mirror that has to clear the lens, so they can have much closer registration distances, therefore you don't need retrofocus lenses (or at least not until a much wider field of view). No retrofocus means fewer elements, means better optical quality. -- Larry Colen [email protected] sent from i4est -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
