Brian, I did some reading on this lens and it seems to be a unique macro lens. I couldn't find out if it is just for the crop sensors, or if it would work with a full frame camera. Do you know?
It's made for crop sensor only, but like nearly all 3rd party lenses it uses the EF mount not the EFS so it will fit to fullframe bodies. Far as I recall it can actually do a good covering of a fullframe sensor as well; far better than most would expect. I think its also pretty safe on most (other than mount type, many EFS lenses can have recessed elements that hit the mirror when it flips up) fullframe bodies; but be careful/test it out/research that element yourself.
It's a very neat little lens and I do like it a lot. For close-up work and general shooting its a neat little lens, however its got some fallbacks.
1) It's AF is macro style - its a little noisy and slower than ideal. Very usable, but not lightning fast nor quiet; its also not HSM/USM so you can't use the focus wheel without setting it to manual (and its got an odd system for that - there is no switch, instead you push the focus ring forward to lock it into AF or pull it back for manual).
2) It's aperture is only f2.8 - now that is good but most 35mm are getting into f1.4 territory or wider - can be a light gathering limitation in comparison to regular 35mm lenses.
3) It's working distance at 1:1 is impractical. You're so close that you will be overshadowing the subject with yourself, camera and lens - which makes lighting a tricky aspect (workable if you've the right gear, but not ideal).
Personally I love it for being a little macro lens for the macro addict and doing good close-up work. I can throw it on and indoors or outdoors don't have to worry about being too close to anything. It will do macro in a pinch too if I get close and position my flash right.
For this kind of work that hte OP proposes though I wouldn't use it.
In fact for things that don't actually require macro magnifications a regular telephoto lens can often be superior because you shoot from further away which helps increase depth of field; without having to resort to focus stacking. IF you've limited space though I'd say look to at least 60mm or longer macro lenses - its a more workable distance to use and gives you more ability to easily setup good lighting for the subject.
Tools of the trade: Canon 400D, Canon 7D, Canon 70-200mm f2.8 IS L M2, Sigma 120-300mm f2.8 OS, Canon MPE 65mm f2.8 macro, Sigma 150mm f2.8 macro, Tamron 24-70mm f2.4, Sigma 70mm f2.8 macro, Sigma 8-16mm f4.5-5.6, Raynox DCR 250, loads of teleconverters and a flashy thingy too
