DA* 16-50 SDM motor failure...

Been Quoted £300 to get SDM fixed...
Only paid £360 for lens....
Anyone know a place who will convert to screw?..

Have you seen the youtube videos. Nothing needs to be dismantled

First point would be to try and get the SDM working by turning the focus ring while attempting to AF.

If that won't work then get yourself an old body (K-5 or older) and convert it to screwdrive yourself, it's pretty straightforward. If you need help then let me know.

That is twice the price I paid at John Pyle, the official repairer, for my 50-135.

You can convert to screw drive with a simple software fix, it's easy to do.

Do you have contacts for John Pyle could be handy.

I strongly recommend a quick switch to the screwdrive mode if you can - save yourself a lot of money, get faster response to AF (esp. compared to an ailing motor) and also no hassle of SDM failure in the future.

The only reason to stay with SDM would be the quiet focus but even then screwdrive is still not bad.
