Marc, I have a Japanese friend in Tacoma who could do the translation for you. But my question is, who give a rip what resolution numbers are? That number hasn't been useful in judging lens performance since the 50s. The MTF and OTF (by Leica) are much more useful and gives a better description of lens performance. And I would trust the BAS tests. You can get a copy from Leica. (BAS is not related to Leica). ========================== Eric Welch Grants Pass Daily Courier
