The problem with a Dslr is that whenever you ask someone else to use it, you always end up with blurred out of focus shots, so when you look back at your photos it will be like your wife went on the honeymoon on her own!(as you end taking all the photos) Just take a good quality compact that can shoot RAW, there'll be plenty of other holidays for the whole camera kit but only one honeymoon.
The results I've received when asking others to photograph me/us are not blurry, out-of-focus shots. (I set the mode dial to Program AE, and confirm that the shooter knows how to half-depress the shutter button to achieve focus before releasing the shutter.) Rather, the problem is more often poorly composed shots (heads / feet cut off, trees or poles "growing" out of heads, zoomed too far in / (way) too far out, etc.)
That's why I always carry a compact CF tripod (my Oben CT-3410 weighs < 3 pounds, folds down to < 17 inches and supports nearly 17 pounds) and an intervalometer. It's actually quicker and easier to set up this rig and get the shot(s) I want, than to find a reliable-looking passer-by, introduce myself, ask him/her to take our photo, instruct him/her on how to use my camera, etc., etc., and then -- as often as not -- get disappointing results, anyway.
happen a lot when other vacationers / tourists are in the area watching me set up, is that they ask me to photograph them in the same setting, using their camera. (And then, usually, I have to ask them how to operate theirs
To the OP: when you return from Mauritius, share your dodo bird pics with us!
