I use a digital camera on the job, taking as many as 100-120 photos per day sometimes.
I"ve been using Samsungs for quite a few years. I have yet to wear one out.
I always carry a backup camera with me, identical to the one I"m using, "cause it would be the pits to be a hundred miles from home and have a camera fail. I"ve only had to use the backup once. When I"m doing an inspection, I carry the camera on a lanyard around my neck so both hands are free to hold, and write on, a clipboard.
I once tripped on an uneven carpet and banged the camera against a pool table. The camera shut down with the lens extended. I got out my backup camera and used it for the rest of the day. Back in my office, I retrieved the memory card out of the camera to get my pics, and noticed the lens was cockeyed. I pushed on it with my finger and it popped back into place and retracted. Worked fine again. In fact, I"m still using that same camera.
