That's why you need to get him a rigid body like a Colorpack 2
Focus if done by lens rotation. The front is fairly smaller so he can press the button easy.
It's also very lightweight. Runs on AA's.
But still, just seeing him holding the camera makes me smile a lot
I went looking through the landlist and figured my first Polaroid probably was a Model 3000 "Big Swinger". I remember the rotating red shutter button...
