This is something I have tried to figure out for a while -- why use an infrared remote for a camera? The camera will see the IR if it is accidently pressed during exposure. I would go with RF myself. --- > 3. Most of them have an optical viewfinders. Video cameras don't seem > to have this problem since an EVF is considered to be a feature. Why do you dislike an optical viewfinder? Do you want to eliminate the mirror flipping up and down? The mirror flipping up and down would be impractical for video, you'd have to use a beam splitter, which reduces available light. --- Canon made some mirrorless SLRs -- see the following wikipedia article: http://en.wikipedia.org/wiki/Pellicle_mirror --- Does anyone make a high resolution display that is small enough to use on a camera? My video/still camera only captures 720x480, even in still mode, but even so the viewfinder resolution is a lot lower than that, so I can't tell how much detail I'm getting. I suppose with the 12 Mpixel (or whatever they're up to this week) sensors you can just assume you're getting a lot of detail, but I can't assume that with only 720x480. With video, even 1920x1080 isn't enough to assume you're getting the detail you want. --- There are some small high resolution displays made by Samsung --- there has also been some talk of OLED displays recently, but those are really expensive. --- > 7.

IIRC optical viewfinders have special patterns in the groundglass to aid focusing. But above you say you want an electronic viewfinder. I think manually focusing an electronic viewfinder would be problematic. What I'd like to see is a good interface to allow the user to select what part of the screen they want to be in focus. And have a button to semi-lock the focus. The auto focus would still track the object if it moves slightly, but is prevented from jumping to another object that is closer/farther away. Similar interface for auto exposure. --- It wouldn't be too hard to have the lens on the EVF sensor (unless you are using the main CCD, which you probably are, but whatever) put the standard microprism structure in the middle, which would make it easy to focus even in an EVF (just move the focus until the center is all the same color, just the same as an optical microprism). _______________________________________________ Open-hardware mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-hardware
