Hi to everybody from a newbie on the forum, and now for my problem...
I recently bought a used 5D mk11 as well as a Sigma 180 macro lens (from different owners ) planning to expand into macro photography, now for my problem.
1. After checking the focus aquisition at near minimum focus distance by using the back button or in live view I found that I had to micro-adjust to +20 to get near perfect results, so my first reaction was to fault the lens.
2. However using the same lens on my 1D mk iv no micro-adjustment was needed, so now the 5D is at fault.
3. HOWEVER switching to my 300 f2.8 lens I get perfect focus on both the 1D and 5D.
Do I just accept the adjustment on the 5D/lens combo or what else can I try??
