Also learn how to quickly change file names. I didn't realise I could do that, as I only bought mine a day before leaving NZ, and was travelling for a couple weeks through Thailand and Cambodia.
By default I was getting images such as 1A6A0001.jpg
What I do now, is every month I reset my counter, and change the file to
etc (with the number 0001.jpg added to the end)
Makes it so much easier to categorise and publish these photos on my blog by date.
Or even events. Such as F1__ , or SWIM say as an example.
Exposure expansion is under C. Fn I: Exposure
If you're shooting people/weddings/bright objects, may be worthwhile to use
Highlight Tone Priority, which you're probably already aware of
C. FnII, (point 3 again).. BUT, you're limited from ISO 200-3200, instead of 50-6400 (when expanded) - so not so suitable for low light sport events, also noise in shadows increases, as the exposure is focused more on the highlights.
Coming from using a 20D for 2 1/2 years, I had also grown accustomed to 5 fps shooting speed.
C. Fn III - point 16, you can set the High speed, to 10 fps, and then Low speed to something more suitable for everyday use (I use 5, as mentioned, and use this setting 99% of time, as whilst on 10fps, it's often hard to do a single shot when you're just learning the camera)
- So in camera I shoot burst setting of 5 fps (displays as 3 squares with an L), set up using AF-Drive button and big dial
Finally for * focus, and recompose method, mine's setup as follows:
C. Fn IV, Operation
Point 1 - set to option 3 - AE lock/metering + AF Start
Point 2 - AF-ON/AE lock button switch, set to 1 - enable
Hope that helps
