Does the A7iii shoot 10-bit video in 4k?

[BlueCosmo5050]

I remember hearing that it was going to before it came out. Well, now I have a chance to buy one and I've looked at a few YouTube reviews and none of them even mention it. That was one of the selling points to me.

I shoot a 5D4 and am happy with it but I was going to get an A73 with a few Sony FE lenses as well as an adapter for the Canon lenses but I can't find that much out about the video features other than just random videos that are test shots for the person.

Anyone have the run down? Can it record video to both slots like the GH5? How is the high ISO compared to the A7S ii? I'm assuming it's good being only 20 Megapixels.

I am also looking at the A7Riii but because I want it for video, it seems that the A7iii has the advantage of going full frame without alias and moire and it over samples. The A7Riii can do full frame but it's pixel binning, meaning I'd always have to shoot Super 35mm mode for my liking. The A7iii I take it that I could shoot full frame and not have to deal with those issues.

While we are own the subject, what would you recommend as my first prime lens to buy with this? Obviously I have a lot in the Canon world but I want to have a few FE lenses.

A7III records 8 bit 4k video.

Even in HLG mode and that is bad because the most HLG ready TV's just play 10bit HLG and can't play the Sony A7III HLG files correctly.

No 10 bit for the Sony A7s. I would recommend you get a Metabones adapter for your Canon lenses and pick up a GH5. For video it's the better machine for many reasons.

Yes, it can record video to both slots simultaneously.

It is actually 24 Megapixels... and the ISO performance in video seems to be slightly better than the A7S II from the lowest ISO up to high ISOs, only at the highests ISOs the A7S II seems to have a slight edge.

Autofocus with adapted Canon lenses is not really relible for video. Manual focus works fine. If you want to use autofocus, you’ll need to use native lenses.

Explain further.

One of the reasons I would use the A7R3 or A73 (not sure which one I am going to get yet,) is the full frame high ISO performance. My 5D Mark IV does pretty well for high ISO performance but I hear the Sony does even better. I hear the GH5 is done after 3200.

Can you tell me some differences between the video features in the A73 and the A7R3 because I am looking at both.

If I get the A73 I plan on getting probably a Sony FE 24-70 2.8 because that's mostly what I use for video and usually a 35mm prime.

If I get an A7R3, I may end up switching to Sony completely because that would mean I could also bring my photography over and not just video. However, for photography I do like to have at least 30 Megapixels, which is why I'd prefer the A7R3 for that. I did own the original Sony A7R and obviously back then it just wasn't good enough in professional situations.

The things that makes me want to keep going with the Canon 5D Mark IV are: The auto focus for video seems to be flawless. Even in low light it's rare that there is any focus breathing or that it doesn't lock on and stay on. Obviously with photography in the mirror the focus system is superb as well.

Another thing is the over all look of the video. I am a colorist and I am hired to color grade video sometimes from an outlet in ATL and I have personally color graded a short film that used C-LOG and S-LOG 2. I was able to get them to match enough that most people would not be able to see the difference. However, C-LOG is way easier to grade and looks better even without doing much.

The final thing that makes me unsure of what to do here; I have a really nice kit. I have lots of flash's, 10 batteries, a lot of nice lenses, in fact I have some L glass that I haven't even really tried out yet.

Although, I don't think I'd loose too much money on it honestly and in reality I don't need a lot of lenses.

The reason I have more lenses with the 5D4 than I normally would is because of the crop factor. So, for example, I normally would record most video content with a 24-70 but my 24-70 doesn't go wide enough in 4k because the 5D4 is 1.7x crop. Which looks similar to like an A6500 from Sony at 1.5x crop (The eye can't tell the difference in 1.7x and 1.5x), or Super 35mm mode with the A7R3.

I HOPE this helps you guys see what I'm doing and where I stand on all of this so you can help me in a more specific way.

One big question I have after that last comment.... Does the A73 in 4k look as good as the A7R3 in Super 35mm 4k? I don't like the A7R3 in full frame 4k because I don't like pixel binning, alias and moire. I'd rather have the crop than have that. I remember Sony putting it out there that the A73 was going to be able to do full frame full readout and there would be no need to put it in crop mode, unless one wanted to zoom in or something?

You guys have said it will record video to both cards at the same time that's a big deal as well.

I can get by with focus peaking, not doing auto focus. I am friends with a famous YouTuber who does photography that you'd all know if I said his name but I don't want to name drop, I only bring it up because he says he is getting sharper results out of his Canon lenses on his A7R3 than he is the Sony equiv. The 24-70 2.8 mostly, and I do own the 24-70 2.8 ii.

Can you tell me some differences between the video features in the A73 and the A7R3 because I am looking at both.

Main difference is that the R3 cannot do full sensor width video without pixel skipping - which reduces high-ISO noise performance and image quality in full frame mode. The R3's extremely high resolution becomes a liability in this regard.

A7III can sample the entire sensor width (6k) and then it downsamples to 4k.

High ISO is the GH5's only weakness, I have both the a7R3 and the GH5:

The GH5 has much better IS; 4K frame rate flexibility; unlimited 4K recording; no heat issues; greater depth of field to avoid undesirable refocusing; more lenses that avoid focus breathing; access to Metabones adapters that would "speed up" your Canon lenses f stops and help offset high ISO issues for you.

Maybe I'll wait for the A7R4... Because I want full frame with no pixel binning but on the photography side of things it'd kinda suck to go back to 24 Megapixels. I like to crop in a good bit. I'd love to have 42, the most I've ever had was 36 with the original A7R.

I guess another reason to wait would be 60FPS in 4k... I'd really like to have that.

I know my 5D Mark IV puts out huge file sizes for 4k but the footage does look stunning and I have no complaints with the way it looks. I am able to get 12 stops of DR with C-LOG. But it doesn't do as well at high ISO as the Sony. It does okay but not as well.

For example, at 12800 ISO on the 5D IV, 4k looks no different than 1080p. It holds up well enough to use but after 12800 it's done.

I typically don't shoot in extreme ISO's anyway.

I thought about going GH5 since it does 60FPS 4k and using Canon glass but the Canon auto focus system is so good in video I feel like I'd end up using the Canon all the time just because I've seen so many reviewers complaining about the GH5 AF.

Now I understand people have been doing manual focus for years, in fact I started with the 5D Mark ii, when it was new, and I manual focused with it, the 5D Mark iii, the original A7R, the 6D, lots of other cameras.

But now that technology has moved to the point that I can actually trust AF during video use, it's hard to go back after getting used to that.

I think you would probably be better off sticking with Canon, and possibly even getting a dedicated Canon cine camera. Man they are expensive though.....
