In reply to Bob Kemp:
Could be I´m talking complete b*llox here, but:
I don´t know what you´re photographing; I go mostly after birds, so I have to be quick. I always work with the "manual" option, and there are only a few buttons which I need; my fingers now know where they are, so that I never have to take my eye from the viewfinder and look for them on the camera. They are:
1. Changing from single shot to quick series and back
2. Switching between adjusting shutter speed and adjusting aperture to get an optimal ISO
3. Adjusting the exposure
I always use the internal setting to get both a jpeg and a RAW-file for each picture; the editing possibilities with the RAW files are basically unlimited, so if I´ve for instance deliberately massively over-exposed to get more colour detail on a dark bird sitting against a light sky, I can correct that later with the editing programme (I use FastStone, free and fairly basic, but I´m an amateur and it covers my needs).
Very willing to be corrected here; I´m in an ongoing learning process but having a lot of fun.
