Hm, I read the thread you pointed to, but I wonder: are you saying that you don't have access to the "AE-L AF-L" button via USB? If you do, you could let people focus via that if they want.

I'm not sure how to interpret the firmware information but it says:

Firmware version:
A 1.3.2
B 1.3.1
C 1.3.0

Is this something that will (can?) be fixed in a firmware update?

When my D750 is set to continuous high speed shooting mode (CH), a single tap on the unleashed trigger always takes two pictures. Is this intentional? I would consider it a bug.

I recently noticed that my photos look much better when they're in focus. So I thought maybe I can even get sharp images via the unleashed, but unfortunatelt, I can't seem to figure out how I can tell the unleashed (sitting on a D750) to focus before triggering. It seems to be impossible. I am start...

Why is it not possible to search this forum for frequent words like focus? How on earth am I supposed to find posts about focusing if I can't search for that term. Makes no sense to me.
