Pentax DA 17-70 SDM Repair Video

Thought some of this might find this video helpful (not my video):

Also, looks like there may be another resource for SDM Repair (video author).

Me try it! I would not even think of it! I do not know how he so easily picked up those tiny screws and just popped them in, must be a special magnetic screwdriver. The SDM on my 17-70 is on life support, I can keep it working if I use it at least once or twice a week. Amazing how small the motor is. Not willing to put up with the issues with this lens, I got the 16-85. The new lens seems like it has a much stronger more robust autofocus motor.

The person is using European screwdrivers (see Leitax), so maybe it is a European source.

This service is in Sofia, Bulgaria. They exchanged the SDM of my 17-70 four years ago and the lens works very fine.
