Hello,
I\'m using industrial cameras with 1/3 and 2/3 inch single cmos sensors. If want to use your converter with my cameras but I dunno how it should be done. If I understand correctly, I still need a C mount lens on the camera and a thread converter from m27 etc to one of the thread sizes that you support.
1) Is there any problem with 2/3 inch sensors? What is the distance of the projected image on the groundglass and what is the size of it? Is it 43mm diameter image circle? I read somewhere on this site that the gg distance can be fine tuned. If I have this info, I can see what kind of c mount lens will be able to focus there properly and fill the full frame of my cameras.
2) A question for industrial but also any camcorder. When using your converter, does the camera have to stay fixed at all its settings, focus distance, iris setting, zoom setting? In a set and forget way? Is the camera lens competely disabled when using a DOF adapter? Autofocus not possible and all that? So I have to use the new Canon EF lens to set zoom, focus, iris? Or can I also change the camera iris settings? Any sideffects? Also, is light measuring through the lens changed in any way (expect darkening)? Will auto exposure (shutter/gain) work or I have to rely on manual settings again?
Btw, if the grain is static, it can be removed on batch without artifacts. In the uncompressed video I use at least. DV should code it so that more artifacts will be introduced when removing it.
Thanks:)
