I get it. Spotmatic F I've been carrying around has a lock, and it's nice that my dog doesn't take pictures as much anymore. But it also means two-steps to take a picture, possibly missing the shot.

I'd rather flick the button over if I see something than have to wind on. Just easier to do. I am in the habit of keeping the camera ready, but sometimes that means putting the camera away with a cocked shutter. So the button lock is a useful feature.
