A9III EVF Problem

p.1 #1 · A9III EVF Problem


It seems almost certain this will have to go to Sony.
A few weeks since purchase of A9III.
Maybe someone has seen a similar problem....

When looking through viewfinder, I see multiple blue vertical lines.
Evenly spaced, about 8 of them.
In a dark environment, they are still there but rather than the usual very noisy display, I get a lot of blue noise.
On playback, the lines change to seeming random artifacts.
The rear LCD is normal.
Permanent issue, ie always when shooting, for playback of every image.

With the LCD and actual photos being fine that pretty much points to a viewfinder issue. Sounds like a trip back to Sony is in order. bummer.... ☹️

Must just be a faulty EVF....off to Sony it goes.
If this was purchased new I'd just return it and buy another. I don't think this is a common problem so I wouldn't worry about it happening on a second copy. If returnable I'd certainly go that route over dealing with Sony service.

I'm in Australia.
Consumer law regarding replacement depends on whether fault is classed as minor or major.
I believe this will be considered minor.

I think I will be stuck with the less desirable option, Sony repair.

There is a major failure with a product when it:
is unsafe.
has either one serious problem or several smaller problems that would’ve stopped you from buying the product if you had known beforehand.
is very different from the description, sample or demonstration you received.
can’t be used for its expected purpose and can’t easily be fixed within a reasonable time.
If a product has a major fault, you are entitled to your choice of a replacement product or a full refund.

Minor failures include smaller problems that don’t fit into the major failure categories, for example, loose threads on clothing or a broken remote for an electronic device.

If your product has a minor issue, the business is only obligated to repair it free of charge – it doesn’t have to offer you a replacement or refund.


Although, who'd buy a camera with this EVF fault?
"that would’ve stopped you from buying the product if you had known beforehand."

Then again, who'd buy an electronic device if they knew the remote was broken?

I own one. Unfortunately, this is definitely not normal

Under Australian law, who decides whether something is minor or major? Can you contact the dealer you bought it from and ask for an exchange?

I imagine that would be the most expeditious route. And the most desirable one. No matter how expertly something is repaired, I would always prefer one that has never been taken apart and put back together

Just another data point for you - I have had my A9iii for about a year and a half and this is definitely not nm normal. Good luck with getting this resolved!

I don't know how they will see it but to me a wonky EVF is a critical fail for a camera. I'd call that a major fault even though you can continue to take photos. But the EVF being your main window to the world is not a minor issue.
