SfB, you may not have a need for a grid on the viewing screen, but I find having one that corresponds to the ‘law of thirds’, the accepted way of positioning objects in a photo or painting to be very handy, particularly with horizons and verticals. Not all of us are as perfect a photographer as you are, although, from what I’ve seen of your pics, good as they are, you’re no Ansel Adams. I would guess you don’t lower yourself to use such crude equipment as my Lumix or an iPhone, but then, Henri Cartier-Bresson never used a fancy SLR, and his photo’s are as good as anything you’re likely to turn out. The grid is an aid, one I’m more than glad of, in the same way as filters, monopods, beanbags, etc, are to achieving a photo that’s level and sharp.
