That´s why I the full frame sensors will be more relevant for today's MF market than 135.
DagT This is one of the concepts that has somewhat escaped me, why full frame sensors are more appropriate in a MF body then a 35mm format body. Earlier threads were talking about 35mm frame sized sensors. If you put a 35mm sized sensor in a MF back you have the same set of problems that you have with APS sized sensors in 35mm based bodies. Lens magnification factor, no really wide angle lenses, needing higher resolution lenses due to having to enlarge more for any given print size, etc. A MF sized chip would solve that but would cost more and have MF's disadvantages to 35mm. Less lens choices, less depth of field compared to the same angle of view in 35mm, slower flash sync with a focal plane shutter, slower top speed with leaf shutters. Also, at full resolution, it would take longer to write to media and less could be stored onto the media card. Pentax is also saddled with the problem of not having an interchangeable back MF camera, the 645's interchangeable inserts don't count. So they would need to either design an interchangeable back MF camera, a MF digital body that takes existing MF lenses, or a whole new body and lens system. My best guess for that, if they were to do any of the above, would be the digital body taking existing lenses. You then beg the question of how much is enough. Pixel resolution is somewhat a bell curve, at some point you will have enough pixel resolution for most applications of most users. At that point the pixel wars will probably end. I'm GUESSING that a 35mm sized sensor will be able to hold enough pixels (not necessarily at that point yet) for most amateur and professional needs. It then makes sense to me to build around a 35mm camera system as opposed to a MF one. Those pros that need much bigger files then a 35mm sensor could provide can always get MF backs. Most wedding/event photographers already have a 35mm system in addition to any MF equipment they have. Butch Each man had only one genuine vocation - to find the way to himself.
