How much does a SDM deactivated DA*16-50 worth

JohsonChou · 11-06-2013, 11:38 PM

I disabled my DA*16-50's SDM to use screw driver mode, because I just got enough of SDM. (Yes, it can work on any model)
The screw driver mode is very fast and accurate...
But I wonder how much can I get if I wanna sell it. Should it be the same price? Higher? Lower?
I lost the lens rom backup, so I can't flash it back.

As for me I'd pay a little more for your lens as I know I'll allways have a working AF with it. I don't care to much to have a silent SDM so I'd prefer the screw driver mode.

I would say it's probably worth $20-50 more (and closer to the higher number for an older lens) than the same lens without the SDM disabled, since the user won't have to worry about the motor failing.

Edit: While I am a bit concerned about the noise of the in-body AF motor, the K-3 uses a brushless motor. While users of older cameras will have to deal with noisy AF, this will not be an issue for K-3 users.
