Sony A7Sii Issues! Don't Buy Yet! BUGS!!!

We've owned a Sony A7Rii since it's release and have been pretty happy with the camera.
It was a no brainer (we thought) and got the A7sii as well on preorder.
I mean everything looked better on paper.

We did a commercial spec shoot (thank god it was a spec) using both Cameras and boy we're lucky we used both cameras.
I've shot on a F55 before and learned about the exposures on SLog3 vs SLog2 and we shot with a DSC One Shot as well so according to spec we had good and legal exposure.
We monitored both cameras on a DP7 OLED with REC709 de-log Lut's and looked fine on a 7" screen

Once we loaded the footage into Premiere, oh boy..... terrible banding in whites (not even highlights and under 60IRE) and weird green tinting in the shadows even when the whites were balanced.

Did browsing and found quite a few people with the same issues.
But the most informative one and exact same problem was recorded on this post.

http://www.eoshd.com/2015/11/sony-a7s-ii-review-part-1-major-sunspot-defect/

It's pretty bad!
It's pretty much UNUSABLE!
if you need to shoot immediately you should rent a a7rii.
a7sii once sony fixes the firmware, it should be ok.

Has anybody else own and experienced these issues?

I was considering that camera for myself - saw loads of reviews and stuff and no one talked about this. I'm glad I came here because now I searched for those issues online and found people with the same problem. Maybe I will wait for a firmware upgrade!

yea the problem with most reviews is they're not really using it in actual or practical settings. Controlled studio and chart tests are great but not enough.
EOS HD is pretty reliable (tho biased at times. which we should all be to an extent)
has more close to realistic tests imo

Philip Bloom has a pretty extensive review on the camera, he is usually legit (as far as we can tell at least). Sony seems to have paid him to do a bit for BBC on this camera but still, on his blog he doesnt have anything really bad like this to point out, and he took the camera around the world to film a long piece.
But yeah, some people might not encounter issues depending on what they are filming - he films with an external recorder, may be way he doesnt encounter issues dont know.

It seems to be a compression problem so using an external recorder seems fine. the eos hd thinks it's compression as well causing artifacts.

Hey Miguel, you can always rent a Sony A7S II on KitSplit if you'd like to test it out before you buy. KitSplit is a community for local creators to rent cameras and related equipment. Check them out here: http://bit.ly/215caqU

Same issue here. Shot an interview against a white wall and terrible banding in slog3. Honestly haven't been super impressed by this camera so far. It's really the 420 8 bit that's my main problem.

8bit slog3 is a bad idea to start with: it has 256 values per channel for 14 stops... It's asking for banding.

Great point walter. i didn't think of the 8bit part. especially because i just got so used to shooting at least 10bit and 12 bit raws.

I can see how that could be an issue, and everyone's mileage will vary, but I'm looking at dailies for a corporate we just shot today- all the b-roll was A7S II- and lots of white walls. Even pushing the color in Premiere the white walls look fine in our footage, and they're not "super well lit" walls, either- lots of tonal grads.

Not all units do this, I own an a7s II and it's never done that and I've shot directly into the sun many times already.

Just to clear up the info on this thread, the sunspot problem was exclusive to shooting in PAL, so NTSC people naturally didn't run into it. It has been fixed via firmware now.

Disagree completely and I'll back it up with proof.

This as an example shot on the sony a7s II and there are no black sunspots, and only color banding shot noticeable on 1 sky shot and yes I shot every single scene with slog3. If you don't know how to grade, then buy a canon t3i or something.

for me it was in the source log footage. hard to judge the Log on built in screen and dp7 didnt seems to show issue but it was evident on a properly calibrated 24" reference monitor. unfortunately i may have a bad unit. which is a greater problem in qc from sony.

Most of the images in your video linked above don't have any solid colors that would have banding. But the two shots that have images of the sky have bad banding issues. Specifically the shots at 1:20 and 1:23. It's not so a grading issue, it's an issue with the 8 bit codec.

There are banding issues in the link you provided above. I saw in 2 shots, and I am using my iPad. If I get on calibrated/bigger monitors, I may find others.

I've found 6 banding MAJOR issue in the link provided. I'm on 5k retina iMac. I've just bought the A7s ii would have like to know that before. Slog3 seems unusable... May I get a a7r instead?

We love our new toys and want to get them as soon as possible. Problem is camera is not "camera" anymore. It's computer with the lens. It's like installing any new software, there are always bugs and companies will call them BETA. With cameras however it's different, first they go on sale and then you keep getting fixes with firmware, but nobody calls them BETA... For $3000 you'd hope for better...

All in a rush to be on the market uicker than the competition.
Only Canon and Arri seem to take it easy with their time to market, while BlackMagicDesign and RED always seem to overpromise ;-)

I have been detecting a horizontal noise pattern that is pretty significant when using Slog-3 between ISO's 1600 and 10000. Once hitting 12800 the noise pattern seems to clean up significantly.
See my test video here: https://youtu.be/aB7WgSGY0YU
Youtube compression makes it hard to see, so I have the raw video available for DL here: https://www.dropbox.com/s/vsij4c1dvhvkoq6/A7sII_NoiseTest2.MP4?dl=0

The video seems much cleaner using Cine2 gamma here: https://youtu.be/d2yybsokLkc

Is anyone else having this problem? I have a replacement body showing up tomorrow and I will run another test to see if maybe I got a lemon.

P.S. This is after installing the new firmware released on the 20th that that was meant to fix the sun spot problem some people were having.

Interesting that Cine 2 gamma fixes the horizontal noise issue. Perhaps this would help with the banding as well. I've heard some things about Cine 2 and Cine 4 gamma being better for compression/color/banding. It seems like s-log may be too aggressive for an 8-bit image.

There is a known noise issue when shooting 4K SLog between iso 1,600 to 10,000. Hitting 12,800 and the noise cleans up considerably. However coming DOWN iso levels, 10,000 is clean but one more step down and the noise returns. The fact that iso 10,000 can both be clean or noisey dependant on which way you scroll through the isos spells firmware issue to me. Time will tell. Sony have been made aware of the problem by many people including myself with a comparison. I've been told it has been escalated.

Just got mine 3 weeks ago. Footage was shot all in shade. Talent in the foreground. Concrete in the background and I was getting rainbow shape banding.

Are people in this thread, who are affected by the banding issues, contacting Sony about a solution? I'm about to send them a response with my experience.

I just got the weirdest response from Sony about the banding issue. It's the first tier for a solution:
"Thank you for contacting the Sony Alpha Email Response Team.

I understand that there is banding issue when using S-log 3 with your ILCE7SM2 camera. And I apologize for the inconvenience that this may have caused you.
To avoid the banding issue, please try to increase the shutter speed. If the issue still unresolved, please contact our next level of support for further assistance."

Anyone? Bueller?

I just tested cine4-sgamut3 combo and compare 8-16bpc modes after manual grading ( After Effects). I hope it helps to fix bending problem. Please watch it in 1080p @ full screen to see details.

That camera is really a big pile of shit. Seriously the bending in slog3 it's horrible. Not to mention cine 4 isn't a fix for slog3... DAMN
