Having gotten hold of my full frame D800, it’s starting to frustrate me that I can’t really use more than a DX (APS-C) sized crop on my 80ED cause of the damn field curvature!
I’m finding it difficult to get any information on these flatteners for full frame work.
Anyone here successfully using a flattener on their 35mm Chip (DSLR or CCD) and a 80ED? Any uncropped sample pics please?
