I realised almost all other brands have their lens release buttons on the left than on the right of the lens mount which makes it very awkward, at least for me, to change lenses with a good grip on the body. On Pentax body, I could just press the lens release button with my middle finger yet maintain a strong hold on the grip and then mount/dismount lens with my left hand. Isn't Pentax wonderful to have thought of this or am I missing something?
