How did you go Jason? did you end up buying one of the macro's you mentioned you had listed.
Thanks Troy for your write up!,very interesting as I would like to get another macro in the future-most likely get the Canon 100 mm F 2.8 EF-S.
But from what I have read else where,and your wisdom back this up,is that no manufacturer can make a bad macro-the recipe must be so,that they always come of the production line, sharp,regardless of brand.
I was most interested to read your comments on the Tamron 90 mm,I will certainly be checking this one out a bit more-I am sure it would be cheaper than the Canon EF-S 100 mm,and come with a hood in the box!
Anyhow a most interesting thread.
