Colin, the Custom Menu gives you control over various aspects of the camera. The simple menu just gives 6, which is all you can see on the screen
The full menu gives you much more, but as the screen will still only show the same 6 you need to scroll down to get access to the new commands.
Even with these extra commands you may find some greyed out and not accessible, this is usually because the camera is on Auto. If you switch to Programme, Aperture Priority or Shutter Priority for example, you get control of these settings.
Welcome on board from me, a site advertiser and member. Seen as you got a great camera to start with drop me a line if you need help with any of your printing requirements or future equipment purchases etc, etc. If shopping local say “Hi” from me to Des Urche (Bray Photo Lab) and Paddy Kelly (Photocraft).
