NewMexiKen has ordered a new camera and is reviewing the online literature in preparation for its delivery next week. I thought this was pretty good advice:
When using the viewfinder
When operating the diopter adjustment control with your eye to the viewfinder, care should be taken not to put your finger in your eye accidentally.
Because of me, they have to say that now.
I’m not conviced that they haven’t seen me use a camera!
