I have been considering getting a 6X7 roll film back for my 4X5. My purpose is to reduce my film costs for some shots shots and for practice, and still have th e 4X5 option for the hopefully dynamite shots. There are a couple of basic ques tions I've been wondering about.
Reviewing resolution charts for LF lens opposed to lenses intended for use on a 6X9 view camera or many of the MF lenses, it would seem that the resolving power of LF lenses is appropriately designed for the 4X5 image size. With the roll f ilm back, can I still expect to get respectable sharpness, say a good 16X20 enla rgement as a reference point, or an image quality comparable to a decent MF 6X7 camera. Or is the 6x7 image too much of a compramise for typical LF lens?
A little more basic would be how to determine the image size on the ground glass . I have unmarked ground glass. I've thought of using a sharpy pen to outline the 6X7 image on the glass. Are there better ways without buying new ground gla ss?
Thanks for the help.
