I am looking to include a Macro lens to my collection. By all accounts either of the Canon 100mm IS or Non IS are both great lenses, no external rotation, quiet focus USM, quality glass and image.
The Tamron 90, also seems to get great write ups, but has the external focus (dust and the like issues) unlike the Sigma APO 150 and the Canon 100.
So, I was thinking that the Sigma has the zoom lenght, gets great write ups, but do I have a lenght fetist going on?? Not sure.
My last Macro lens, was with all my Olympus gear, 50mm, it worked a treat, but very invasive for small hard to target creatures, ok for flora.
So once again I'm in two minds as to which way to go,
The Canon 100mm,
The Sigma 150mm,
Any help, susgestions and any one that has the Sigma, your coments would be great.
