I was just looking at the price of the Apo Sonnar. Some dealers offer instead the Milvus 135/2 and put in brackets (App-Sonnar). Are the lenses, except the stylish, but ugly finish of the Milvus, identical?

Yes, they are identical... it's actually mentioned in the intro of the review

The upgrade price you pay is not only for the new design (which I personally don't like, if it was only about the design, I'd prefer a ZF over a Milvus any time), but also weather sealing.

Maybe Marcus will repeat the test with the sigma for comparison. It was a 5* lens on the canon test.

Depends on whether I can get my hand on one soon
