"Accurate manual focusing a bit tricky though because the focus path is relatively short for a macro lens. "



1. How much is the MF rotating angle?

2. Do you men that you have MF problem during the target test or when you perform target/resolution test?



The non OS version rotates 270 degree and I find it just good enough for MF at macro distances. The infinity setting is different story.



PS Nor of macro lenses are good here. E.g. tokina 100macro rotates more than 270 degree while the difference between 3m ant infinity is just few degree.

Sigma 150 non OS is just a little bit better.

I don't mentioned canon 100 macro non L - it rotates just 170 degree from MFD to INF.

Just go for the APO Lanthar ... you will keep on pulling forever there. ;-)

I will need to check. However, it was quite a nightmare to test the Sigma due to the focus characteristic. However, that was at non-macro distances anyway.
