I'm using a tamron 90mm macro, it's 1:1 and it is the best working distance-cost focal range. Anything less than 90-100mm and your overpaying for the working distance you get and anything more and your overpaying, IMO
. Probably the best macro in that focal range is the canon 100mm f/2.8 USM macro, it does a little better with autofocus than the competitors (but really by the time that makes a big difference your using manual focus anyway) and it is completly self contained (for example my tamron lens extends as I focus closer, the canon won't). I'm completely happy with my tamron, it's a very sharp lens and it does what I want it to, btw
, it is not a di
lens, I bought it used for a song....that said, Ido see myself upgrading to the canon lens at some point in the future.
Here are a couple I took with the tamron (hand held, so a bit softer than I would have liked) and a couple of extension tubes last week.
Here's a couple with just the tamron, 1:1
