Canon 40D review

For those buying a used camera it is very difficult to go wrong with a Canon 40D. I owned one brand new when it originally came out two years ago. I then changed to a Nikon D300 for the AF capabilities but have since sold that camera and returned to Canon (and a used 40D).
The reason was simple, whilst the D300 does have (vastly) superior tracking AF tracking capabilities it lacks a few things that the 40D nailed for me. Namely mirror lock up with timer. This may sound trivial but for landscape work I find it invaluable. Virtually no noise at base iso to iso 400. I use my cameras primarily for landscape (and 70/30 landscape / nature) and low noise is a priority. The CF dial makes it simple to change options without delving into the menu's. For example I have my CF set up to:
C1 - my primary tripod based landscape settings - Mirror lock-up enabled, 2 second timer, spot metering, iso 100, f8, daylight white balance, single shot, adobe rgb colour space, manual mode
C2 - my walkaround settings - mirror lock up disabled, iso 400, f8, centre weighted metering, single shot, daylight white balance. Aperture priority.
C3 - wildlife - mirror lock up disabled, iso 100, aperture priority, high speed shooting enabled, spot metering.
The build quality of the 40D is not bad, better than the XXXD series but not up to D300 standards.
Image quality is as good as it gets up to 1600 iso for 10-12 megapixed crop camera. The 40d has a very wide dynamic range (wider than Canon 5DII, D300 etc) and it seems to capture highlights and shadow detail very well. I struggled with my D300 in capturing highlight detail and the 40D is (slightly) better in this respect (IMHO). Ergonomically the camera is great, lots of external buttons for changing functions. It does have a pointless print button which cannot be changed to anything else which is irritating though. The on/off switch is also located is a ridiculous position (by rear dial) which makes turning it on/off in a hurry cumbersome (same goes for 5dII, 50D, thankfully canon changed it on 7D).
The AF is not up to D300 standards but for landscape is perfectly fine. For wildlife too it has been shown to be very good although tracking is not up to D300 standards.
AF using centre cross type point is extremely accurate especially using a fast lens (2.8 or faster). I am using a 50 f1.8 and 70-200L f4. These both work flawlessly on the camera and focus quickly (even non usm 50 1.8) and accurately.
Overall if you want a superb camera, its difficult to fault a 40D (except for a few niggles! ;-) ).
