It doesn't happen every time, but once in a while, my A68 will focus on something (almost always correctly - I do love the focusing system on this and the A77ii), the focus point indicator will turn green..

.. but pressing the shutter results in no action at all. Even if done repeatedly, or if I go off and focus on something else.

Turning the camera off and on again gets it back working. I can have the camera on a tripod looking at a still life subject, have this happen, turn it on and off, and it will focus on exactly the same point but allow me to take a photo.

It happens with a variety of (all?) lenses, and it's possible it happens more with some than with others - I don't have the data. To give an example, I took it with the Sony 50mm f1.4 to a concert, took 138 photos over the nearly three hours, and I had to power cycle it two or three times.

In three months of having an A77ii, it's never once happened with that one.

(From what I can see, the A68 has never had a firmware update, so this is with version 1.00 for the A68 and version 2.00 for the A77ii.)

Hmm, doubt it is a firmware issue but there's a couple things to try. Does this happen with different SD cards also? If so have you tried switching to manual focus and then get the same result? Does the shutter button feel different than the a77ii at both half press and full press? Right now I'm thinking you could have a faulty shutter switch.

Yes, and without one in the camera at all.

No it feels the same - switching to use the A77ii had no surprises for me at all in relation to shutter feel. I've seen reviews where people have talked about how light the shutter feel is on both, but it's 'gentle resistance to half way, then a bit stronger to full' on both. Blindfold me, and I wouldn't know which shutter I was pressing.

I've just tried a quick test (using the 35mm f/1.8 on superior auto settings), and it did a multiple exposure shot first time, then did this. Changing to MF on both the camera and the lens had no effect.

After a power cycle, I can snap away (fifty shots and counting) with no problem.

Ah, it's happened again - again in superior auto mode, after having done a '3-Shot Cont Shooting' picture.

I'm beginning to think that's not a coincidence. Annoyingly, that message flashes in the viewfinder so quickly that it's not always noticeable until you hear it happen.

My next step would be to try a reset of the factory settings. This sometimes clears any glitches that arise. If you do this, just make sure to write down any custom changes you have made to the settings so you can easily re-do them.
To see is to enjoy. To see beyond is to rejoice.
