Hey everyone :), I'd just like to know what your recommendations are for lens taking very close up shots. What I would like to do is take shots for use as textures in 3D applications such as Bryce. Also, I've found in that shots I have taken, the outermost edges are out of focus. My camera is the new Canon Eos XT Digital, so I'm sure the problem is most likely me lol. Any advice would be great. :) -Dave

If you mean the new 350D with its EFS mount I would think the EFS Macro would be an ideal choice lighter and smaller in weight and designed to suit this cameras sensor if costs are a consideration then look at Macro lens by Sigma and Tamron

IMO the Canon 100mm f2.8 macro is superb. If you are taking your shots straight on then the DOF wont be too much of an issue, but if there is any depth to the shot than a macro lens may not be your best option. Even with a macro lens stopped down to f32 there may be a little blurring at the edges, depending on the angle and depth of the subject. A wider lens will offer a much deeper DOF.

I would agree with Simon very much here as I own the 100mm USM myself the 65mm EFS has less of a telephoto effect and having been designed for the 1.6 sized sensor in my view is a bit sharper than expected at the edges .. The angle of view that Simon mentions is a key issue when perhaps the wider 50mm macro may also be worth considering and a even more cost effective solution

I have donequite a few shots for Bryce textures and never had the need for a macro.Depends though what you have in mind for textures. Maybe you can clarify that.

You've been a great help, Thanks!
