LOL.. Thanks Fred. Yep, it can get a little touch and go at times, but I generally get away with it giving a smile, a nod and a salute.
For the hard target, I've found that the secret is to focus on someone else or something at similar distance, lock it, then swing on to your target and fire. It's when you spend time focusing and composing on them that people become uneasy with a camera. One of the other things is to use a lens with focal length anywhere between 100 and 200mm and keep your distance. The Oly 75mm is a great length because the Micro Four Thirds system doubles it to 150mm - which is ideal. Image stabilisation is important here - because you're always hand-held and sometimes in dappled shadow or even darkness.
Failing any of that, as soon as you take your shot, move to one side and fire again - pretending that they were in the way! Works most of the time...
