Will AF.C Cause Undo Wear on my K5?

Just curious if keeping the Auto Focus set to "Constant" is asking for trouble down the road. I never had my K10D set to constant, but recently read about having it set to constant in order to capture the image in correct focus using the back button instead of using a half press on the shutter button.

I expect to have this body for a long time (enthusiast) and don't want to screw myself by using a technique that isn't recommended.

Thanks

It would damage the camera only when you get annoyed enough with the constant AF adjustments and decide to spike your camera like you're in the NFL.

Other than that you're OK.

It's safe to use AF.C.

I am very happy that I set my K-5 to use the rear AF button. The AF switch can stay in AF.C all the time. Holding the rear AF button gives AF.C. A short press of the button simulates AF.S. No button press with a quickshift lens allows manual focus.

Im very happy camera that I set my K-5 to use the rear AF button. The AF switch stays in AF.C all the time. Hold rear AF down gives AF.C. A short press of rear AF simulates AF.S. No button press with a quickshift lens allows manual focus.

You'll be OK. It just drains the battery a bit since the motor is constantly torquing. Honestly, your shutter and mirror assembly will probably bonk out on you before anything else does.

Electrical motors are, thankfully, very old technology and are very reliable, so the failure won't be a limiting factor for you. It also should be a relatively cheap fix.
