To be clear, all Jack suggested was having the back trigger electronically so as to remove the need for a physical SHUTTER to fire in the camera body or lens. As for the mirror, it will be still be needed in any SLR design for MF backs using CCD sensors. As mentioned above, CCDs cannot stay "on" for long enough periods of time to support live view. CMOS presents a different discussion, when and if they become viable for MF back capture.
Jack, I was not intending to associate your name with my tech-useless-post
Sorry, I should have been more precise. In fact I understood perfectly that you where just talking about the shutter.
I went further with the mirror, and just in my name. Precision done in my OP edited.
Yes, CCD heat etc...I knew that, but sorry again for my lack of knowledge when it comes to engineering but my question is, How that is possible then?
http://www.luminous-landscape.com/reviews/...s/sam-ex1.shtmlThis camera also has CCD.
I'm completly confused.
Is it that the MF manufacturers+sensors makers consider that they don't have to modernised their backs, or is it that the issues are indeed important and they have truth limitations today?
Why CCD seems to not have those issues with smaller sized sensors? Question of temperature?
Thanks.
