This is a nice test. Jello less, but not eliminated with APS-C. I think the images have more dynamic range, better color, and less noise in full frame. Look at the shadows in the kid's shirts for instance. The map colors are more saturated in full frame, and less noise. I don't see much change in detail between the two, particularly the maps, which is surprising. Michael

My guess is the a7S is doing full sensor readout, even in 1080p, which is increasing the jello effect over other full frame cameras. I am going to guess, that unlike the GH4, the a7S will not have an increase in jello effect in 4K (no data yet to prove this hypothesis, so we'll see later). Michael

OK, maybe I have already gotten spoiled by the a7S full frame mode, because the APS-C shots look soft now and lacking some punch (although realistically, as good as most other cameras). I'm really liking some of the a7S full frame footage I'm seeing now. Michael

That's very impressive. Some great shots there! What camera settings did you use? What did you do in grading, and what software? Any noise reduction used? Did you run into any bugs/lockups with the a7S? Thanks! Michael

This is a disappointment that Nikon did not include 4K in the D810. The more we see, the more it is evident that shooting 4K, even for later downsampling to HD, has huge advantages. I just saw a green screen keying test with the GH4, and even with the GH4's compressed internal 100 Mbps codec, it beat out the Black Magic Cinema 2.5K with raw and ProRes. Not only did the hair used in the test have more detail in the key area, but even in the areas not at the border of the keys.

That's what i was thinking! If what he showed at the end was really what he was seeing with his eyes, this camera may be bought by more law enforcement people than videographers. I can think of a lot of interesting night footage that could shot with this camera, such as a nocturnal animal documentary, underwater footage, night sky, etc. Michael

Very informative video. The results were surprising. Michael

Does anyone really believe that given two cameras at the same price with the same features, people would pick the crop sensor over a full frame? Let's face it, the Speed Booster is a very helpful product, but is also a bit of band-aid. Any time you put things in the optical path, they introduce their own negative byproducts. The cleaner the optical path the better. Michael

How about using an external recorder with the uncompressed HDMI 4:2:2 out? Internal D800 vs. Ninja with D800:

I agree. The footage is not pretty to look at, but if seeing something is better than nothing, then it has its place. Michael

Didn't see anything about 1080p/50-60, just 720p/50-60. I am hoping Andrew does an A/B test, so we can see what can be gained by using the Ninja. Tests on other cameras I've seen online, the difference between internal and external is very subtle. Michael

What you don't like "Park Dream" or whatever it was called? :) I really like this music video. Very entertaining, and looks great! Did you use an external recorder? What picture profile did you use? What kind of grading? Thanks for posting. Michael

Maxonics, if both cameras are doing one to one pixel mapping at 4K, why would the a7S be more prone to aliasing? By the way, everyone, Sony calls this camera the "a7S", not "A7S" or "A7s". Don't shoot the messenger. :P Michael

Good review. I have been wondering about this. I think I heard Panasonic has been claiming that the issue is only with TRS plugs. Your tests prove otherwise. I surprised Panasonic blew this, on an otherwise stellar design. I can't imagine Panasonic can fix this with firmware. It seems they didn't isolate the audio circuits sufficiently. Therefore, I am holding off purchasing the GH4. Michael

LOL Cheers! Michael

That would assume 0 transmission loss through the Speed Booster, and that you could get a 0.5 Speed Booster. The ones I have seen for M 4/3 have been closer to 0.7, and one stop. I've never seen any measurements as to what the losses actually are. Michael

A lot of people suspect this video is fake. Michael

It's called judder. I have seen a couple clips with this being a problem, but most are fine. There were also reports of this on the GH3 from time to time. Proper camera use and settings (shutter angle, panning speed, frame rate) can reduce this. Are you encoding to 100 Mbps? @Darwich, did you mean the shutter angle too high or too low? Increasing shutter angle should smooth (blur) the panning. Here is a link that may help. http://www.red.com/learn/red-101/camera-panning-speed Michael

Well said. Michael

I think we are in agreement then. Michael

You keep going back to "most people". I'm not talking about "most people". I'm talking about pros and prosumers. A Canon Rebel is not in that category. As long as there is a debayer, there will be a need for high MP sensors. The 12MP sensor in the Sony is a stopgap measure. That's the best they can do right now, and hit their ISO targets. That sensor only has 6MP of green, and 3MP of blue and 3MP of red. I guarantee in 10 years, the replacement model will have far more than 12MP. Michael

Is the iPhone your tool for shooting video? You seem a little sensitive about this. I'm really not following where you are coming from at this point. It sounds like you believe higher megapixels=worse quality. To each his own. The future is going to be higher megapixel sensors, and more processing power. It will trickle down to the less expensive cameras, as it has in the past. That's just technology moving forward. There will be diminishing returns, but we are not even close to that, because the in-camera processing has been pretty weak. Higher megapixels are moving bodies in the pro and prosumer video world. Look at the sales of the GH4. It's backordered for a month. It's using 8MP to create 4K video. People are shooting 4K, and downsampling it to 2K. I don't think anyone thought this many people would be shooting in 4K, even when the delivery medium was 2K. Michael

Did you guys update the firmware in your lenses? Supposed to help. Michael

Interesting review of the A7S by The Camera Store. They liked it, but weren't super enthused. The good news is they said Sony finally weather sealed an A7 series camera with the A7S. It is a shame Sony didn't put 10 bit in the HDMI output, especially if you have to go to the trouble and expense of connecting an external recorder for 4K. 10 bit is even a requirement for Rec. 2020 for UHD.
