Originally posted by ytterbium I dont think it's the future for cameras. More likely for the sensors. Have you seen how much additional stuff they attach to 5D in odd ways to make it really suitable for professional video. Its made for photography. Video is nice, just like in P&S camera, but belongs elsewhere.
Talking about the software engineering. In hardware it's a bit different. In huge number of cases, when you need to squeeze out maximum performance you have to hardcode or even hardwire a lot of behaviour and functionality.
Which additional stuff you think of? You mean, the follow focus, monitor and etc? I don't really see anything unusual you have to attach on the 5D which you don't have to attach on a let's say Red One. Also, bigger and bigger productions start using HD-DSLR-s (think about the House finale). I think it is a very nice process. A lot of amateur filmmakers get opportunity to make outstanding shorts and features. I think it shouldn't be mixed with P&S videos or customer level camcorders. It is something very different. I don't know why it should belong somewhere else. Why can't photography and videography merge into one camera?
About software engineering: I know, I agree, I've had the opportunity in the past to be a part of a digital cinema camera team, so I know a bit about them, and I would be very surprised if the K-7 cannot have manual controls in movie mode, or at least displaying the current shutter and ISO on the screen. The reason I have written these posts, is because I am very afraid, that while the K-7 might have the capabilities to be a much better camera in the videography field, Pentax won't update the firmware just to drive the sales of their upcoming cameras.
Update: Also, I can easily believe, that K-7
cannot have 1080p and 24p modes, these could be easily restrained by limited hardware.
