A few weeks before Christmas, we got a lens in our lab for which there is no equal from any other manufacturer (to my knowledge anyway). I speak of course of the Canon 65mm MPE, a manual focus macro lens that is capable of magnification up to 5x life size (in comparison my 100mm macro lens is capable of 1x life size). As no one was using the lens, I took the opportunity to play with it last night.
Macro photography is hard, and its only harder when you trying to do something at 5x magnification. The issue is mostly that your depth of field is so shallow (i.e. <1mm) that its impossible to focus. I had to play around for quite a while to get it right, and the low light of the kitchen wasn't a help either.
I think that if I want to do any serious macro photography, I'll have to invest in a macro light as well as a macro slide rail. I did manage to take an abstract involving rice on a Teflon pan.
Technical Specs: Canon 5D, MPE 65mm, 90s @ f/11, ISO 100, ~4x magnification.
