Hello,
I have just bought the aptus 12 and after testing it with Horseman swd 2
and digitar 24 I saw that this lens is not compatible with the leaf 12 db.
The problem is not that the lens cant cover the hall ccd,it is that it appears
severe color cast at the edges of the image,that cant be removed even after
doing the white shading procedure.After the white shading procedure the results are:unsharp,very grainy,and with green spots image.
After searching in the phase one site I found that there is an issue with p65+
and cant work well with symmetric wide lenses like digitar 24-35- 47
and rodenstock grandagon 35 and45.The lenses that can work well with p65+
are the digarons witch are designed non symmetric.From phase one I had the answer that because the aptus 12 has similar ccd with p65+ will work well with digarons.What I want to ask is if any one has experience working with aptus 12 and digaron 23 because it is very difficult for me to find that lens for test and I dont want to invest the very many $ with out being sure there is no problem whit this back-lens combination.
Thank you in advance
