I think GH5 still has the best IBIS.

    As far as the 10bit color, I was watching video comparing the two and surprisingly there was almost no difference between 10 and 8bit. Best explanation was with the high internal compression you end up losing much of the gained color. The effects of bit rate on color bit depth has been brought up in other threads. You can't make conclusions on specs alone.
    10bit is one of those things you only need it when you need it. 8bit can look great and if you don't need to push a grade very hard then 8bit is likely more than enough. Where 10bit becomes important is when shooting a situation where you would get banding in the shot. Once an image has banding it will always have banding. Its kind of like bitrates in compression. 150mbps IPB is likely more than enough for 90% of shooting situations. Its that 10% of an explosion of surf waves or whatever that can break the codec. 10bit is kind of the same thing. Most of the time there are enough colors to reproduce the scene in 8bit. Its those rare situations where it is not enough where 10bit can help and render a clean gradient.

    Grading today is very sophisticated with 32bit float which creates in between samples during grading. As long as there are no visual gaps then 32bit float should be able to fill in new samples. Unlike upscaling where the math is very complex to recreate details, 32bit float wants to create a more subtle smooth gradient which is easy for math to do. So a lot of online videos comparing 8bit and 10bit are inaccurate when they try to push a grade and say they look the same. Of course they do because visually the shot looked fine in both 8bit and 10bit anyway. The 32bit float could easily fill in the values as the grade was pushed for both.

    Online examples need to shoot something that would normally fall apart with 8bit.

    10bit like dynamic range, extra bit depth extra audio bit depth and so forth is all about overhead in a professional environment. Its to have more than needed so there is room to adjust or to make sure something subtle isn't lost. We like more DR so we don't lose the subtle details in the highs and/or lows. We like intraframe formats vs 150mbps IPB to make sure we don't get macro blocking on complex scenes. We like 10bit to make sure we never get any kind of banding in any shot.

    If you're shooting LOG, aren't you way better off with 10-bit? On the R5, I believe you only get 10-bit shooting LOG and only get 8-bit shooting non-LOG. Something like that.

    I thought the primary advantage of intraframe compression was ease of editing. I buy the argument that interframe breaks more easily, but I'm not sure I see that in practice.

    So a bit of a side-step into talking about auto-focus and the S5.

    I've been on the pre-order list for the S5 over 3 weeks now (just got a notification from B&H that the S5 is still back ordered). I had already sold off my be-loved GH5 in expectation of buying the S5.

    As it became apparent that I wouldn't be shooting with the S5 for the couple of things I had scheduled, primarily shooting an episode of a zombie show called REANIMATED, I had to find an available, cheap, stand-in.

    Long story short, I ended up getting a Olympus EM1 MII, primarily because it was cheap ($700 out the door), has non-crop 4K, purportedly had good auto-focus, and I was interested in the colors some people rave about. I knew the IBIS was as good or better as the GH5, and that it wouldn't have anything near the codecs available for video.

    So after testing the crap out of it, I've been borderline shocked about a couple of things. One, it has much better colors then the GH5. Like not close. Color is subjective of course, but I felt like I was always fighting the GH5 to make the colors look good; to make the image a bit less video-y. While not offensively bad, I could never get the image to "sing" no matter what profile, grade, or bit rate I used.

    The color straight out of the box on the Oly is superb. Essentially don't have do a thing to it. While the dynamic range on the EM1 MII is limited, probably a stop less then the GH5, the better colors are worth it (it should be noted that I usually do not shoot log, but rather try to get the best look straight out of camera). Even though it's 8 bit, my shots of a clear blue sky didn't band at all. While I wouldn't want to grade it, that's the point - I don't need to.

    But that wasn't the shocking part (I long suspected the colors would be better then the GH5). What was shocking is how good the auto-focus is (assuming you have the latest firmware). It, like the Sony A7sIII, has some sort of voodoo magic happening where it seems to know what you want in focus. The transitions are usually smooth, precise, and rarely hunts. Once it's locked on, it doesn't pulse or hunt.

    Simply put, it's good enough to rely upon for money situations, like the bride coming down the isle or a big one-chance only special effect. It just works.


    It's as game changing for me as was good IBIS. Once you've had good IBIS, you're going to be very unwilling to use a camera w/o the feature. The same is now true for me for auto-focus. For small shoots with no crew/small crew, it allows the DP to concentrate far more on framing and performance as opposed to pulling focus. While it isn't perfect, it's pretty dang good (especially considering that it's a used 3.5 year old camera from a company that literally was sold off this week).

    While I know the S5 smokes the Oly (and GH5) in dynamic range and in low light, I'm not so sure it beats it in color science. I know the S5 doesn't have better IBIS, and most importantly, it has vastly worse auto-focus. I previously thought good auto-focus was for blogs only, but no more. It's an incredibly usable, needed, tool for the indie film maker.

    All of which has me re-thinking my would-be S5 purchase once the camera's back in stock. It's hard to go back to the non auto-focus farm once you've seen Oly....

    Olympus had an AF update last year that people raved about. Never tried it, but it wasn't always like that.

    A lot of people always said good things about the E-M1 Mark II.

    And it's great to see/hear you say that about AF because it's very frustrating when people don't realize how useful reliable AF is.

    Regarding back-order @ B&H, I ordered the S5 kit at Best Buy last night and it is supposed to be delivered tomorrow. I missed the free Sigma, but FexEx says they’re delivering before end of business tomorrow.

    Yeah, that's why I'm waiting for it get into stock at B&H - presumably I'd still be in line for the bonus lens....

    ...If I order it.

    That's how miraculous getting usable auto-focus has been to me. Easily as big as discovering what good IBIS can do.

    And make no mistake, I can pull focus. Started making movies back in the early '90's, moving from a wind-up Bolex, to an Arri-S, to early video cameras like the Canon "chainsaw", the JVC GYU 100, all the way up to the modern hybrids/video cameras.

    But the Oly is the first camera I've used that had truly usable AF. Now thinking I'll stand pat and see what shakes lose in the next couple of months in the MFT format, or maybe wait a year to pick up a used A7sIII.

While I love almost everything besides the legendarily poor auto-focus on the GH5: its dedicated buttons, IBIS, resolution options, and menu system - the actual image is not awesome. As in not at all awesome. Color heavily baked into every profile (which all are essentially the same one with more or less color & contrast); it's now easily the worst color science of any major camera system. The image gets the job done, but nothing more...
    I really shouldn't comment, as this is highly subjective, but to me, the S5 is exactly to the the tee identical to the S1H (sans anti-aliasing filter) as far as 4K image quality when using V-Log and V-Gamut. They are the most accurate color reproduction of all the latest 2020 cameras, with Sony being dead last. In the last year, do you know how many times I used a color profile other than V-Log?

    Once.

    People who buy these cameras want superior dynamic range, not Rec-709 limited stuff. No one ever uses profiles other than V-Log, even in m43 unless they are starving for light.

    Nice job. Looks good I can feel your style. No matter how you film or what camera you use most of it comes down to the skill of the operator. I think people on forums get carried away with their opinions. I'm glad we don't use the same cameras and film the same way.

    Nice color, Brandon. Nice compositions. What apertures are you using on the Rokinons? I find they can get "interesting" wide open but this all looks pretty clean to me
