Magdy Eisa Saafan

Could you explain more, what you exactly need?.

Graham Dellaire

Hi Magdy

The older CSU-X1 optic vignettes produces an image that will not fill the Flash 4.0 Chip and you will also see field effects on the edges where you don't have the same illumination. If you put optics in front of the camera you could magnify the image to fill the chip on the Flash 4.0 camera... losing resolution but reducing field effects.

In any case, what I have learned from Vendors is that you are better off just autocropping the image in software so you maintain resolution but don't have to save the unused "black" space in each image and also crop out field effects.
