Im working on a long term project shooting a range of products - some are .75 cm (and smaller) and others are as big as 9 inches. I use my 5dmk2 for the bigger items and it's great. I've been using a 1d3 with a 100L for the smaller stuff but I end up cropping a lot - say 20-30%. Does anyone have experience with the 1d3 and the 7d? I'm thinking the reach and the extra pixels would help me. I'm trying to hold out for a 1dx (not necessarily for macro) and wanted to save funds. I had a 50d 3-4 years ago and hated it - the noise was awful. Is it worth it to go to a 7d?
