    Posted: 15 August 2019 at 17:15
With my recent purchase of a very nice used a99 body and CZ 135/1.8, I've pretty much committed to A mount as my primary platform. However, I really like EYE-af and want to use with my many A-mount lenses. While I haven't ruled out an upgrade to an a77II, the a68 has advantages of size, weight and price, and price is very important after the other recent buys. So can anyone share using the EYE-af feature on an a68 (or a77II for comparison)?

Some of the areas I'm most interested getting info:

Does it work well with screw drive lenses, or are SSM & SAM lenses better?

Are the EVF/LCD adequate, especially in comparison to a77/99 if you can compare experiences.

General satisfaction with a68.

Thanks in advance!

The A68 is the same size as the A77II(and A77). It is a bit lighter.

The A68 AF system is identical to the A77II. Both seem to focus on eyes in normal AF-C wide area mode. The Eye AF button/feature only works in AF-S after the camera has already detected a face. The eye needs to be near one of the enabled AF points for it to work.

Post-A77 lenses focus best on both cameras: 16-50, 18-135, 55-300 as far as DT lenses.

There are advantages to using 2000+ Post 7 D lenses over even older lenses: range limiter, maybe stabilization.

The EVFs and LCDs are okay. I found the A68 EVF to be better than the A65 EVF--it shows more dynamic range. I have no experience with the A77.

I bought the A77II used after using the A68 for a year and a half. The controls are a bit different. If you are used to the A77 you will probably be comfortable enough with the A68.

I should list my A68 for sale.

Thanks OC!

Your response addresses several of my concerns directly, plus raises a few additional questions.

Biggest surprise was your statement that it seems to focus eyes in AF-C wide area. I was under the impression it only worked as you described in AF-s with a button push. So: do you need to have facial recognition on for eye-af to work, can you set it to work on half press of shutter button, or only through a separate dedicated button, and when in AF-C wide how close do faces have to be? On of my reasons for wanting eye-af on an A-mount platform is that I'm getting back into stage photography work. Facial recognition works, but there are times when eye-af would be a better choice. I have an a6300 with a few good lenses, but nothing that can equal the CZ 2.8/24-70 for A-mount. As I have the 2.8/16-50 SSM, that would come very, very close on an APS-C body with eye-af.

Also, if you decide to sell your a68, send me a PM. I have several I'm looking at, but they all come with lenses which I don't need. I would be interested in knowing how much you'd sell it for, especially body only.

Smile/Face Detect. does not need to be enabled. It does it automatically with the shutter or AF-on. I was surprised by it when I got the A68. The A6000 and a7II don't do this, and they have the same AF-S Eye AF limitation.

On of my reasons for wanting eye-af on an A-mount platform is that I'm getting back into stage photography work. Facial recognition works, but there are times when eye-af would be a better choice.

The Eye AF on the A68/A77II is not very precise/accurate. Maybe micro adjusting lenses would help. I've only calibrated the DT 35 F1.8 on my A68 so far. A-mount is pretty much dedicated to motorsports for me.

Also, if you decide to sell your a68, send me a PM. I have several I'm looking at, but they all come with lenses which I don't need. I would be interested in knowing how much you'd sell it for, especially body only.

I've decided I just haven't gotten around to listing it. I would be looking for $400 for it.

My 2 cents. If you like the EVF on the a77/a99 the a68 will be a bit of a disappointment, small and cramped with an odd magnifier. The LCD and VF build is similar to the a58 and a500 series. People who wear glasses say it's fine.
The Camera is fast and responsive without the power up lag of the a99 but not as fast up as the a77.
Screw drive lenses work OK but I usually pair my a68 with a SAL18135 or SAL55300.
The AF works fine but I wasn't blown away by it; an incremental improvement to the a77 for some situations.
General satisfaction is "Meh". Single shot results are fine, continuous shooting results are hit or miss. It's a good "get out and go" good weather camera but not "Better" than an a77.
