Does anyone know anything about this lens? It is a Commercial Komura 210mm (picture in tech. gallery) It looks like it is singel coated, with 4 elements. I haven't been abel to find any specs on it. I have been using it as a light weight 210mm on 4x5 with nice results, but the other day I popped it on my 8x10 and it looks like it covers the whole ground glass with some movements. I shot a couple of test sheets with it but haven't had a chance to develop them yet--probably this weekend since I can only develop 8x10 at night in my semi-dim room/garage
Can someone tell me the image circle, and if it is a tesser type lens or something else. Thanks.
