anyone using either of these lenses with this format + movements? any preference? will the 600 cover more movements than the 355 for close-up copy work?

technical specs would be helpful. image circle at various f stops...

This issue will be driven more by the length of bellows you have to work with under macro conditions than anything. Generally speaking you would be better served by the 355 G Claron because of its shorter focal length. Plus the G Claron is a repro lens to begin with.
