On one hand, I would be curious to see just how good it is. I've never seen a formal test of it anywhere. On the other hand, if it's as good as it's supposed to be then a good test would drive used prices up...and I still need to acquire one cheaply... <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/laugh.gif' class='bbc_emoticon' alt=':lol:' />

DXO has done test for DFA 50mm f2,8 Macro; and photodo.com has MTF data for F 50mm f2,8 Macro. While DXO gave quite a low score to DFA, photodo.com rated F as one of the best lenses (4.6). A 50 f2,8 Macro was tested at erphotoreview.com, with good center and poor borders. On latter site some famous legacy lenses were tested also.
