Go to a camera shop and compare the two side by side. I own the 20D and the design is considerably different from the lower end SLRs from Canon. I personally like heavier/larger cameras for most situations.
Canons do well with noise in higher ISOs. 3200 comes in quite handy for me a lot of times. It depends on the type of shooting you’re doing. When shooting at music venues, the extra speed from iso 3200 is nice.
3 fps is plenty fast if you’re not shooting sequences. The 20D is 5fps and is a bit too slow for a lot of action sports photography. I’d like to have around 8, but most people don’t need that.http://society6.com/grainfarmer Fly Fishing and Landscape open edition Photography prints.

I’ll try to explain some of the differences briefly but thats a task for me 🙂6.0 fps vs 3.5 and the increased buffer size to hadle them
Canon says 6.5 but test have shown it to be closer to 6. Either way if you shoot sports or action higher FPS can mean the difference between some good shots ad getting the 1 shot in the sequence thats spectacular.Digic III processor vs the Digic II and 14bit depth.
Bottom line te files the 40D produces have a richness in tones I didnt see with either my XT or 30D.Better NR.
the 30 and 40D both have better NR than the XTs.1/3 stop ISO increments:
In the XT/XTIs you only get full stop ISOs increments. Meaning 100, 200, 400, 800,1600 (dont bother using expanded 3200 imo ). In the 40D you get 1/3 stop (interpolated) ISOs. Meaning say you want just a little bit more SS for any given shot and your at ISO 400 or ISO 800. Well in the XTI youd have to increase ISO ( and noise) by a FULL stop. With the 40D you can bump it 1/3 or 2/3s. While its an interpolated adjustment and not true 1/3 increments it and and does save you from not having the choice.Better AF and better AI servo.
Waaaaaaaaaay better. While not on par with the 1D bodies the AF/AI servo is to the XTI what the 1D’s are to the 30/40DHigh precision center at f5.6. (read low light focusing)
In fact at f2.8 or faster the 40D offers the only center point on the market currently that offers a diagonal AF sensors on top of the traditional + points.Better build and some limited weather sealing.
Again not on par with 1D’s but its better than the XTIs.Live view.
Really nice feature to have when manually foucsing………Like macro shooting. Long story short. Rather than trying to nail critical focus manually through the viewfinder, you can use live view which not only offeres the advantage of the using the larger LCD you can then magnify the image 5x or 10x. Which when your using a 1:1 macro and azor thin DoFs is a godsend.and on and on.
If its in your budget, even if you hav to stretch your budget I strongly recommend you get the 40D over the XTI.
Few sample images for you.
All shot with the 40D
I use the 400 f5.6L for wildlife Eric although, Â I had and used the 100-400L for awhile before switching to the prime. The 30D ( which I used until Sept) and 100-400L is a great combo for it and you should be able to get some great shots.
As for settings I us center point af and AI servo always and typically with spot metering. The 30D AI servo is pretty good Ive got tons of good shots with it and the 40Ds is in exactly the same, atleast that was my improession during the short period I owned one. It is a bit faster to acquire initial focus.
That said, its still limited. Its hard to put into words but with med sized birds at reasonable distances its fine, smaller faster birds and at closer distances it can struggle. I got into the habit of using short 3 frame burst and then reaquiring focu lock.The 100-400 can be a bit slow to focus for birds in flight but is fanatastic for stationary birds. I did find on my copy that it was sharpest at f8 and at 370mm. Also found that its “sweet” spot was anywhere from the MFD out to 40feet. Beyond that it could struggle to resolve. Not something youd notice on a FF shot but if/when you start to crop those kinds of shots the keeper rate went down.
As to the 40D, I dont know if it offers enough to universally say its worth the upgrade from the 30D.
While I did do just that, it helped that I had a good deal , if I had to swallow the full cost I dont know if Id have done it.That said the 40D does have some imporvements over the 30D. It really is alot of camera for the buck. As mentioned one thing I noticed right away was that the files had a certain quality in tonality thats hard to put into words and quantify that I didnt see with my 30D.
