Canon 1D C vs Sony A7S 4K - dynamic range - preview
Andrew Reid replied to Andrew Reid's topic in Cameras
Indeed this is what I see as well. No bias! When you all pick up your 1D Cs for cheap in 2015 you will thank me for recommending it -

Well that's weird. I'm sure I said I shot in S-LOG2. Oh wait. I did Not Cine1. Not Cine2. We are talking about S-LOG here. Nope that's incorrect, I'm sorry to break it to you. Just imagine I have a friendly face and a smile whilst I give you the bad news and we won't get into an Internet Debate. The very deepest blacks start to break up on the A7S with noise because you reach the end of the usable dynamic range, it's not an ISO issue. You can see the same in a raw still shot at ISO 200, just bring the shadows up very high. What do you see? Yes noise. That's why we talk about dynamic range and USABLE dynamic range. Loss of detail? It's a dynamic range test shot. I didn't even focus it properly. When I do the resolution test shot I'll make sure the focus is nailed on both cameras. Didn't need to on this shot. Post fact rationalisation more like. Haha. Yes. We agree on that. Maybe the Internet Argument can be averted after all. New years resolution. Avoid internet arguments -

With my eyes! You can't see it? Crushed blacks and a highlight that burns sooner on the A7S S-LOG? C'mon dude. Black is black you can't bring it back, same as white. -
The GH4 has more dynamic range than people give it credit for.

I'm not sure how you've graded that, it doesn't look like what I get. Might not be your fault, you are grading a heavily web compressed JPEG after all. I get a stop more detail in the highlight and at least 1-2 stops cleaner shadows... Top A7S 4K S-LOG and bottom 1D C MJPEG. (Click to enlarge to see the noise grain in the shadows and on table surface) That's what I mean by 'usable'. You have to crush the blacks on the A7S to get rid of the noise in the shadows. On the 1D C you can leave the shadows 'as-is'. They both have a 0% curve in Film Convert on to try and exceed the maximum dynamic range that's usable... to show as an example. No artistic merit I know it looks awful on both! S-LOG 2 needs fixing for 4K it isn't working right. And how is purple chromatic aberration the fault of the camera? It's a lens thing anyway. -

I'm not seeing that. Very fine noise grain on the 1D C files and NR is off in the menus. The A7S shadows just look worse. Muddy unfortunately. Like Doug said earlier. He was right. -
And dynamic range / smart range + is definitely off?

What happens if you don't enable video mode (it's not really a mode, more a standby preview thing) and just hit record straight from live-view?

The purpose really was to look at the source file and see the differences. You can certainly grade it that's what you're meant to do with LOG. Though even after grading I'm not happy with what's going on over HDMI with S-LOG. Needs a fix! -
It's fine in 2D 4K as is the IMAX 24p stuff. I know what JG means about focussing audience attention on the wrong details though But you can only do that if standing really close the screen. 4K on a big screen from the right viewing distances is simply gorgeous! Now I get more distracted when something is too soft but because I'm used to it, I can just forget that and enjoy the story.

It's HFR 3D that's the problem not 4K. It destroys the mystery of the image and makes it seem real. Still depends on the subject matter though! Reality is good for showing reality not so much for showing a wizard with makeup on.

Agree 100%

I decided to put the Sony A7S and Atomos Shogun to use shooting some of the snow over Christmas. Shot in Derbyshire (North of England) in 4K with family and at Chatsworth House. Music by singer-songwriter Anne Haight of Berlin (hear more on SoundCloud here) Read the full article

Try as I might I just can't reproduce the problem at the moment. With Samsung lens attached (30mm F2.0 pancake). Does it still do the exposure change in live-view when the SD card is removed?

The Metabones Smart EF adapters for Micro Four Thirds support Canon IS, it works 100% on the GH3 and GH4. I have the 35mm F2.0 IS and stabilisation is great on the GH4 with it.

I can't make my mind up, maybe buy both.. GH4 & A7S..
Andrew Reid replied to Hitfabryk's topic in Cameras
The 24-105 has a lot of distortion on full frame. The Sigma 24-105 (new version) is better anyway. Much sharper. Consider the 24-70mm F2.8 or older 28-70mm F2.8 intsead. -

It is in the upcoming 4K shootout I'm working on. D750 sensor is actually bloody amazing. The stills are the best I've ever seen. The video is good for 1080p but obviously times move on -

The poor Nikon didn't make it to the 4K party -

I'm pretty sure the A7S S-LOG is better internally. In 4K there's something not right. Would have done my usual trick of 2 stops to the right but the highlight was already burning out. Looks like Doug was right. Anyone know a good restaurant that serves words?
