Ah you have both cameras! Try the same sharpness on the picture profiles. Raise detail from -7 to 0 on the A7S II S-LOG profile and maybe try a prime, I doubt the mega zoom is that sharp even stopped down. Looks closely matched in the grade. Did you shoot Canon LOG 2 and S-LOG 2?

S-LOG 2 is the gamma curve. S-Gamut is the colours. I find S-Gamut 3.Cine better for colour but it's still tricky to grade!

Best review of the C300 II I have read so far, very too the point and based on a lot of real world shooting by Joe Simon http://www.newsshooter.com/2015/11/05/is-the-canon-c300-mkii-worth-it-joe-simon-tries-it-out-and-tells-it-straight/ Interesting to hear Canon LOG 2 is flatter and more like S-LOG now. LOG profiles should be named after the bit depth they are designed to be used... it should be S-LOG 8bit and S-LOG 10bit. It depends though... 120fps on 2.7x crop sensor or 120fps on 2.2x crop sensor with Speed Booster to make it 1.6x with interchangeable lenses? I'd say the 120fps of the A7S II has a high chance of "shitting on" the RX10 II and RX100 IV if shot right The 240fps on the RX cameras is nice but you can slow the 120fps 50% with Twixtor to mimic it pretty well.

30p... right. This is a 25p-only issue. Try 25p 4K full frame and see. Thankfully S-LOG 2 is nice. I don't know what Sony were thinking putting S-LOG 3 in the A7S II and FS5 with their 8bit codecs... when would it be useful? Never!

The kind of noise and colour is perfectly normal, for any camera, if not exposed right.

Cooke!! But the Sigma 18-35mm F1.8 is my current favourite S35 lens for realistic prices

Yeah S-LOG 3 has a ton of noise in the shadows. Like I said 12,800 exposed +2 will look cleaner than ISO 3200 exposed -2, because noise over brightly exposed objects is barely visible. In the darkest greyest shadows that is when you see it and if like in your video at the lower ISOs your entire shot is dark then that is why you see so much noise! S-LOG needs over exposing, then pulling down in post. If you leave it as it came off the card (did you?) or try to boost the exposure, you will get a ton of noise. It isn't like a standard picture profile.

24p or 25p Cliff? 100Mbit/s. It's an 8bit S-LOG 3 issue not a bitrate issue. Switch to S-LOG 2 and the banding is much reduced.

+1 for EditReady! It's Mac only though.

1. Have you checked the eye sensor for the EVF is turned off in the menus? 2. It is under exposure causing the noise you're seeing. Are you in S-LOG mode? You should not under expose the shot and with S-LOG actually over expose it 2 stops to the right on the LCD exposure meter. At all ISOs cameras have noise in the very deepest black shadows. If you underexpose ISO 3200 and look at the blacks, of course you will see more noise in them than 12,800 at the same exposure, because 12,800 will be brighter and you will be looking mainly at mid-tones.

But you don't say why! Why don't you like it? I still haven't got round to trying it yet. 1D C / A7R II / A7S II are keeping me busy. Still a great camera though.

S-LOG 3 is banding hell on the A7S II. Fine for high contrast scenes but as soon as you have a plain sky or wall in a large part of the frame, forget about it. I have turned it off and am back on S-LOG 2. The FS7 and F55 are 10bit for S-LOG 3. The F5 is not 10bit in 4K but it is in 1080p. Sounds like you are in the US shooting 24p. Like I said earlier in the thread, in my experience the problem happens with 25p PAL not 24p NTSC. I am in Europe so need 25p. So are you saying the heat issues don't exist at all? They do. But it only happens with long continuous 4K recordings one after the other. Source - http://eriknaso.com/2015/11/01/does-the-sony-a7s-ii-overheat-i-put-the-camera-to-the-test/ Good idea. The 502 is nice. I am talking about the camera bare bones though using the built in features. Your 35mm prime replaces your 24-105 zoom? Fair enough!!

I have noticed it's almost all European shooters who are reporting the sunspot bug. Sure enough I switch to NTSC 24p and problem is gone. Looks like to only be a 25p bug. So as a temporary workaround until Sony respond just set the camera to NTSC.

If you are not seeing the problem try this on your A7S II 1. Make sure ALL settings that adjust exposure or highlights are turned off and set Knee to manual in S-LOG profile (be sure Movie Exposure mode is set to manual in the main menus!) 2. Disable stuff like DRO dynamic range optimiser 3. Set to XAVC-S 4K in full frame (it doesn't show up in any crop sensor mode like 120fps or APS-C) 4. Point at your iPhone LED, play with exposure - it shows at 1/50 F2 ISO 1600 for me, if you don't see it go brighter on the ISO 5. Now adjust focus to get the back of the iPhone tack sharp, you won't see the problem if the light is spread out like bokeh 6. If not showing the sunspot yet - move camera around until it shows, direct the iPhone light directly into the lens from approx. 30cm to 50cm away, adjust focus 7. If still doesn't showing it is likely your unit is OK and it is isolated to an early batch of cameras or even random units Did that issue knock out the entire sun black? Check the main blog and the videos... it isn't just aliasing around highlights, if that is what you mean? Although that is there on the A7S II again, I've noticed it when pixel peeping!!

Just tried the settings reset and camera 'initialise' option and it didn't solve the problem. Well... it made it go away due to auto exposure and auto ISO but as soon as enabled 4K XAVC-S and manual exposure it was back with vengeance. You might be able to under expose to avoid it on a weak LED light but try doing that with the sun, impossible. A7R II has no such issue, this is purely an A7S II thing. Very disappointing!

It did really annoy me in the summer... The sunny weather mode however boosts contrast so much, it would make accurately shooting / exposing in S-LOG very tricky for a start. The EVF in sunny weather is the way to go, ignore the LCD. But even then the EVF is less than stella - goes invisible when you have direct sunlight coming at the camera sideways.

Lofote, on every new Sony body the Metabones adapter has had issues and required a firmware fix or hardware update. Basically Sony's new firmware keeps breaking it and making it unstable. And I for one am sick of it! That has nothing to do with the EF mount protocol which hasn't changed in years. Sony should get together with Metabones and TEST the stuff... Metabones didn't even get an A7S II early... they had to wait until it was in the shops!

I deal with it by living in Berlin where the sun don't shine!!

The noise in the blacks with S-LOG can definitely be insane but it's designed to all be crushed back to black in post. Like Mr Chapman said in the video, don't try raising the bottom of the curve for S-LOG. I find when exposed +2 it is pretty clean... but if you don't quite have the light and under expose, ISO 3200 ends up looking worse than +2 at 12,800!! ISO is a bit wibbly wobbly in SLOG, I take it with a pinch of salt! With the compressed 100Mbit/s codec the main issue with the noise is how blotchy it gets... because it is a highly compressed long GOP codec, it doesn't do a nice raw-like fine random grain... instead it starts to macro block and kinda crawl, break up. I find a good low light grade can do a lot though. Especially if you do a James Miller style raised blacks LUT over it.

A7R II does the same thing... for some reason in 4K it dims the monitor back down.

Doesn't look like a bad copy, because people have been telling me on social media that they are having the same problem with theirs. Some aren't, but it isn't isolated to just one faulty camera unfortunately. One helpful guy told me he rented two of his out, both had the sunspots, but a 'reset to default settings' in the menu solved it. Maybe it is a bug with a certain option. I'm going to try the reset and hope it goes away.

It is clear on the LCD - big black hole in the middle of the shot. I thought it was a bug with the View Assist at first! Nope. On all my footage. Junked a load of material from that shoot. If you're taking this camera to work with you... don't yet.

I have been shooting with the A7S II for 2 weeks now. Let's really get under the skin of the camera and see if it is worth your $3000. On my retail model (bought in Europe on day of release, firmware 1.0) sunspots and black holes render it almost unusable. It is a complete lottery whether your shot is going to be ruined or not. The next shot is not even in direct sunlight – the black hole is produced from a specular bounce of light off the floor. Read the review

Enjoyed the video and Alister really knows his stuff by the way. Just putting a different perspective out there and it's all up to our preferences what we like. I find S-LOG does allow me to focus on directing and composition, it's easier to expose than Rec 709 and allows for more leeway to correct exposure mistakes in post. I agree with you it has a sweet spot though! Optimal 2 stops to the right usually. Many shoot green screen with Blackmagic cameras... raw is great for that. It isn't so much LOG that causes issues, the compression does.

Indeed. Or Shane Meadows. Good 1080p doesn't look soft when it is thrown at an epic cinema screen to an audience of 200... It only looks soft on a laptop screen with your eye 1mm away! The D750 and BMPCC I rate as pretty good 1080p personally!!
