Upgrade from 40D or upgrading lenses

[Corylus]

The 40D is a great camera. I've had one for a few years and take mainly wildlife portrait shots with it. With decent lenses (I have 100mm macro (non-L) and 400mm f5.6) and some PP I am generally very pleased with what I can get from this camera.

I agree with others who say upgrade glass first. That said I'll also be looking to upgrade from the 40D next year, either to the new 70D/7DmkII offering or possibly the 5dmkIII.

Lense-wise I highly recommend Canon's 100mm macros and the 400 f5.6. I also seem to have a very sharp copy of the 70-300 non-L and love this lens too - very good value for money.

As someone who went from the 40D to the 7D I would say it definitely was a worthwhile upgrade. Although noise levels even at moderately high ISO settings are considerably high, I quite like the overall image quality of the 7D – better than the already good 40D. Resolution, AF, speed and ergonomics are far better in the 7D. But if you are after a camera with superb image quality especially in low light/high ISO situations, you'd probably be better off with a 5DII.

I went from 40D to 5D2 and it is superb for landscapes and macro. Go for 5D3 if you can. You will not regret it.

As for glass go for best you can afford L series preferably

I think the 40D is one of the best crop cameras Canon has made. I've sold and repurchased several of them as friends and family wanted a good DSLR without spending a lot of $$. I finally replaced my last 40D with a 60D (same sensor as the 7D). Meh. 60D is fine, faster fps, etc but I'd take another 40D in a heartbeat. I also agree, stay away from the 50D. Increased pixel density was a mistake.

My suggestion - UPGRADE GLASS with good EF or L lenses. KEEP 40D unless you need better focusing.
