First post, so a big hello to everyone!
I'm looking to add a new macro lens to my inventory and need advice. I'm looking at the ZD 50mm f/2 vs. the Sigma 105mm f/2.8 EX DG.
In my research, I see the Sigma is 1:1 while the ZD is 1:2. Reviews say both are great lenses but slow with AF - which I suppose is normal for macro lenses. Both are about the same price.
Does anyone have experience with these lenses and would the sigma work well on my Oly e500?
