Originally posted by thibs Indeed it is difficult to break. IMO, it goes like this:
* Yes the (un)success of a850/900 is indicative. It does not mean the same will happen to Pentax but it does mean that bringing an FF won't automatically bring the success/sales one would await from such camera. Remember Sony has the FF lenses, and still, it did not work.
* Sony sensor (FF 24Mpix) isn't quite good but then the D3X has the same. Did it sell? Yes it did, quite better than the Sony? I dunno but wouldn't be surprised (relatively speaking of course, taking market conditions into account). So the sensor isn't the only thing. Very important , but not unique point.
Why do people buy FF cameras from Canon and Nikon? I think, because these manufacturers have established themselves as the professional photographer's choice ver the last decades and most pros use already their equipment. Some amateurs will always follow th pros, because tey need the same level of equipment sophistication or they have enough money "to afford the best".
For the pros, there are several decisive points: availability of lenses and system components and service.
We are not talking about a set of three leses (or five) for a start, but about a choice of >10 lenses with the usual focal lengthes and fast pertures, tat pros expect.
We are not talking about the outsourced servicing with turnaround times of many weeks (as many of us have experienced first hand with Pentax).
We are talking about rental stations at large events, we are talking about repair turnaround times of a couple of days and rentals in the mean time. etc. etc.
Pentax has nothing to offer, be it choice of FF lenses or be it service. Why, would anybody, except a few enthusiasts, the entx fanboys, buy into such a incomplete system? Why would anbody risk his business and his economic existience, buying into such an incomplete system?
It's bad enough with the Pentax APS-C cameras, but at least the lens choice is a bit wider. And the bodies are so cheap, that I can buy a replacement immediately, if one breaks - with FF you'll think twice about the cost.
