I am photo enthusiast ; own 5DM3 , 24-70 2.8 , 70-200 2.8 and I've been more than happy shooting with the combo.I mostly shoot Landscape, Night Photography.
However I've been missing some Macro shots lately where I intend to take but never happens with the above mentioned lens.
So I was planning on getting Macro lens and I am confused between Canon 100mm and Zeiss 100mm.
I know the primary differences as AutoFocus vs ManualFocus ; 1:1 vs 1:2 and I am not bothered about cost.
I am based out of India and we don't have an option of renting lenses.
Please help me in giving some real life examples of 1:1 vs 1:2 reproduction ratio.
I am biased towards Zeiss but is it difficult to Manual Focus on 5DM3 because of focussing screen ?
I would be happy If someone having an experience with both the lenses gives and in-depth analysis.
