For using a quality ED triplet and at times an ED doublet, for shooting birds nimals and other daytime terrestrial objects, is there usually much benefit of using a non- reducing field flattener?

My scopes are the SV115T35 F7 800mm triplet and the SV102ED F7 700mm doublet with a CANON 7D DSLR camera.

Steven, You will see some improvement in sharpness towards the corners, however probably not enough to jump out at you.
