Thanks for this. The lever was in fact sticking -- I nudged it loose, it seemed to work fine with my finger moving it back and forth, but on camera the lens caused the mirror lock up still, so yes, I will return it. Thanks for your help.

Just bought a used 20mm f/2.8D lens for my D750. Each shot causes the mirror to lock up. I have to release the lens and turn it twenty degrees to get the mirror to fall again. I love the lens' look but this is unacceptable. Tested my AFS 35mm f/1.8, a 28mm f/2.8D and a 50mm f/1.8D to see if mirror locked up -- maybe the notorious D750 shutter problem -- but no, just this one new lens causes it. Anyone have any idea what is wrong with the lens that would cause this? Thanks for any help.

Does anyone know if you can interchange these trays for the Epson line of scanners? Ie use V700 trays on the V600 or V750 etc? On the one hand I'm sure Epson would try to prevent this, on the other hand the platens are all the same size are they not? Thanks!

<p>Even with my Df (sold, traded down for $$ and a v. nice used D7000) I used center point only focusing and the AEL/AFL (set to lock focus only) to hold the focus and reframe. In great conditions the full AF program can be nice but as soon a tree branch intervenes you're back to the same "tyranny-of-the-electronics" situation as always. Once you get used to working with one point only it becomes second nature -- you find the spot you want to focus on, keeping in mind your depth of field in relation to your aperture, and lock it with your thumb. </p>
