I would think that the sensitivity of the sensor would be constant. But then I know close to nothing about the sensors.

On mine the viewfinder and the larger display are both speced at a whopping "113,000 (approx) pixels". That works out to only 291x388. I suppose having them both be the same resolution makes the software easier. I have yet to find a 720x480 panel. For 1920x1080 there is a large laptop or 2 with a TN panel, otherwise it is 23" or larger. > >> Large format backs have a Peltier cooler to cool the sensor chip to > >> reduce noise. > > > > How do they prevent condensation? > > That is a good question!

According to the fine manual, mine will issue a condensation warning, so it must have some sort of condensation sensor. As far as I know it doesn't have a cooler.

Sounds like the RAW format is defective. Obviously we want to be able to store all the data the sensor can provide.

Right, but you have to navigate the menus with buttons, or the annoying little joystick thingy. If the ergonomics aren't right you have a mess. Opps I bumped the joystick the wrong direction, now how do I undo that change? _______________________________________________ Open-hardware mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-hardware
