I have a 1.4 with my 5d2. Good for low light.
Is this good to copy flat art, say paintings in sizes upto 6x5 ft. Copying for fine art reprinting or buy a f2.5 macro or exchange the 1.4?
I am well aware of most ideal gadgets like Better Light scanning back and other 4x5 film system etc, but not practical; film is just dead, NOBODY to develop film locally, hence the FF camera and a suitable lens+ good even lighting+software like DxO for corrections is the practical alternative.
Which lens, and ideal lights please...
Distance is no probs.
It is going to be a permanent, regular system to produce quality, any other system except film at moderate additional investment, say $2000+ if gives fundamental quality improvement is possible.
