    Posted: 16 December 2020 at 01:22
Hi folks.

So I realized back in late September that my a77ii was still on the original firmware, so I upgraded it.

It seems like ever since then the focus is off. Like, I will focus on the eye of my dog and the focus will be back on the ears instead. This is in a still portrait shot, not anything in motion.

But I did not have this issue before and for a couple months I assumed I was suddenly much worse at taking photos, until I traced it back and realized the first time I took it out and noticed the focus was off in all my photos was right after I did the upgrade.

I shoot with old Minolta glass (primarily the 80-200mm f/2.8 G and the 135mm f/2.8). I also shoot with a Tokina 11-16mm. The focus seems ok on that one, but off for the old Minolta lenses.

Has anyone had trouble with the firmware upgrade and found it doesn't play nice with their older lenses? I'm trying to debate on resetting it or not.

Had you previously set the AF micro adjustment up to correct the lenses and the firmware update has cancelled it out ?
Admittedly , it's sounds like AF is more out than Micro adjustment did .

It sounds more like you have cleaned the sensor and failed to place the mirror back in its correct position .
It needs to be clipped firmly in place .
With the mirror slightly off , AF would be well out .
I think that's the first thing you need to check .

I was not using micro adjust before as the lenses seemed to focus properly.

I haven't cleaned the mirror in a very long time but I can check and see if it somehow got dislodged. I'm generally pretty terrified to touch the thing but I can take a look.

I have had your stated problem. You can not roll back to the earlier firmware.
No problem with Sony DT lenses (SAL1650, SAL50F18) but unreliable with Minolta 5 pin lenses. The one modern lens that also has the problem is the SAL1680CZ.

Auto Focus

Sony ILCA-77M2 + Minolta AF 135mm F2.8
f/2.8 135.0 mm 1/60 100

Manual Focus

Sony ILCA-77M2 + Minolta AF 135mm F2.8
f/2.8 135.0 mm 1/60 100

the focus point was on "SONY".

Strange.

I use my A77II with the latest firmware and have all the lenses mentioned (the SAL1680Z, the Minolta 135 F2.8 and the Minolta 80-200 F2.8 HS APO G), but do not have these focus problems. I did micro focus adjustment on all these lenses and specially the SAL1680Z needed quite some correction.

In fact, most of my lenses are old Minolta lenses (so with 5 pin connection). A lot of them needed micro focus adjustment, but after that the auto focus works as it should be.

On my A55, I have the problems you describe as well with certain lenses, as this camera has no micro focus adjustment feature. The most noticeable is the Minolta 24mm F2.8: focus is off in 90% of the cases on the A55. On the A77II however, it works fine, after I had set the micro focus adjustment.

Were your micro focus adjustments before or after the firmware update? I don't use the mark 2 much and haven't bothered with going through and doing the adjustments.

My A77m2 is running version 2.0 and I never noticed a problem. I just did a quick test with my Minolta 85/1.4G and Minolta 100/2. The 85/1.4 @1.4 seems slightly off (but easily within micro adjust) and the 100/2 @2 seems spot on. Both are 5-contact lenses - the 100/2 being first generation and the 85/1.4G being a second generation lens.

I cannot see by how much the AF is off in the picture above. I assume it was focused on the Sony logo?

re. micro adjust - I did a micro adjust with the SAM 18-135 and the A77m2, I did not feel the need for any other lens (but the 85/1.4G might benefit )

Focus was on the "SONY" logo. No Micro Adjustment. The focus plain seems to be back at the ISO button.
I should add that since the Firmware update there also seems to be an exposure discrepancy. Images that look properly exposed "In Camera" EVF and View Screen look over exposed "on Computer".

So even a factory reset won't put it back to previous firmware?

LABernethy, you're noting the same problem there as I am. The focus falls behind where I'm focused now. I focus on the dog's eye and the focus is on their ears or the back part of the head. This wasn't happening before the update.

I will attempt to micro-adjust them and leave it there to see if it fixes the problem permanently. I've never needed to before as the focus has always been where I want it. Previously I've only used microadjust as a hack (purposely pulling the focus forward on fast moving dogs running at me).

I see all sorts of things to get the microadjust right, including a "focus pyramid." How do you folks adjust things that you find works best?

Factory reset just resets the custom functions and other settings back to the default ( raw / jpeg , etc ).
It doesn't change the firmware .

My a77ii focused just fine and consistently .
Most of my lenses are five pin .
It's running off the final FW , and lenses are all AF fine tuned .

Well, drat. I assumed it set it back to exactly how it came. I had no idea it wouldn't change the firmware back. I wish I hadn't done it now as this is a huge frustration. I feel like I've gone back several years in my abilities.

I've reseated the mirror, but I really don't think that's the issue. I'll try adjusting for the lenses and see if that changes anything. Otherwise, I may take it somewhere to have it looked at. It probably could do with a good cleaning.

Focused on the Sony logo and the plane of focus on the ISO button is a big difference..... Doubt micro adjust covers that. But it is worth a try.

It wasn't me who tried it, so hopefully it should work ok for me. Mine is the difference between the dog's eyes and their ears. So a handful of inches, but just enough to leave the eyes soft. Microadjust SHOULD fix it. I hope.

If it doesn't, I guess it's back to the 580 for me. I can't afford a new camera body at this point.
