That seems to be his current thinking. Re FF (or anything substantially larger than the current APS sized sensor), I am sure Pentax will adopt it when it ever becomes a main stream (which means the sensor cost becomes significantly low), but for now, it is unlikely to happen although I have no crystal ball on that. In general, the larger the sensor size is, the better the image quality becomes, just like in the case of film. But 645D is probably the different beast altogether, and I suspect that Pentax are not really viewing their 645D as an alternative to what is called 35mm size FF digital. The file size would be so much bigger (hey, it's 32MP or whatever!. What storage card do they use, or do you have to drag around a laptop with large HDD? :-), requiring quite a bit of computing power to process it, and people have to invest in the whole new line of large and expensive lenses. With the current proliferation of K-mount lenses, I am certain that Pentax would go FF (if and when appropriate, but you never know. They are just watching as Nikon seem to be doing. APS-C,H size sensors could be developed further), keeping the current DSLR form factor, protecting the investment in the K-mount lenses which is overwhelmingly larger than the 645 lens bases. In the meantime, if the lenses one currently has serve the purpose, there is no need to invest in DA's. If one bought a couple of wide angle DA's, it will take care of most of the digital needs. While I realize some 35mm lenses have CA, purple fringe problems etc (24mm/2.0 said to have the problem), anything beyond 200mm (even 135mm) do not have to be "smaller image circle" lenses. Pentax pretty much took care of the wide angle range and I won't be surprised that more DFA lenses coming out in the future, particularly in longer FL. This does not necessarily mean they are eyeing at FF sensor size, but it seems that Pentax have been steadily changing ALL lenses to digital compatibilities, taking advantage of the necessity to scrap all lenses due to lead content issue (according to Pentax). Canon for example is actually slow in "digitizing" their lenses. By the time people realizes, Pentax might actually be ahead of the game in a few years :-). They really seem to know what they are doing, looking far ahead down the line. Ken -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
