Default 1d 3 vs. 7d

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?

Have you considered extension tubes? The higher end sensors don't just have more pixels, they're usually better in many other respects too. Like less noise, higher light sensitivity, more color depth, and higher linearity. So, I'd try to use the 1D3 at all costs.

There certainly is a point where a less expensive sensor with higher pixel density would be preferable, but it's hard (neigh impossible) to compute that mathematically with so many variables. Comparing two identical photos taken with each side by side is pretty subjective. And it's likely more differences will become prevalent after processing, which is an extremely subjective process.

I totally understand and agree with everything you said, thats why I was trying to find someone with both - subjective is a great word

Get extension tubes on the 1D for the small stuff. Much cheaper and will still give you images as good as the lens and body can produce (no extra glass).

Im going to rent or buy a 7d and compare images. I will also take your suggestions and get the tubes. I will post some results as soon as possible. I can't find a comparison in this macro forum section. Thank You for your advice and opinions - exactly what I was looking for.
