first of alll congratulations to u.
what lenses have u bought with it...
what is your background (electronical or mechanical camera)
check out for your camera that the focus is fast enough. check out as well that the focusing ring (for menual position) works well. with wide rf lenses u may like to use scale focusing, it is very usefull.
the glases for this camera are really really good. u can trust them if u explore them in the proper way.
