Anyone know an appropriate adhesive for the a900 mirror, or other fix? I tried epoxy, and the mirror popped off again.
Thanks!

Double-side adhesive?

Hot glue?

I would assume good superglue is the only option.

Or maybe the stuff made specifically for attaching rear view mirrors to windshields (since it's made for adhering glass to metal and/or plastic).

Superglue, might be good choice, but as you pointed out, it must be some that can do metal/glass contact.

In case of using any kind of superglue or similar, let it harden few days. Cause fumes from these things can easily damage sensor..

NOOOOOOOOO not superglue, aka cyanoacrylate!!! It releases glue vapour and causes stains.

Thanks!
I knew superglue was wrong, but didn't know why.
Rear view mirror to windshield adhesive was a brilliant idea, but the tubes I saw said "for metal buttons" - the mirror has a plastic cover over a metal mount.

I used a different epoxy, Permatex brand (two tubes, mix with a stick) and baked it with an incandescent bulb (I let the lens mount get hot, not good) and it has been good for a week.

I haven't completely tested, but viewfinder focus might be a little off. Is it possible I didn't put the mirror in the correct position and focus in the VF was affected? AF is the same, since AF is off the secondary mirror behind the primary/reflex mirror. Could metering be affected too? I haven't noticed, but metering is in the VF hump reflected by the primary mirror correct?

I didn't want to bounce the camera through the mail if it was something I could fix, but maybe Sony Laredo Service was the way to go.
