That's interesting. How did you find this out, do you have any more info? -
Canon 1D C vs Sony A7S 4K - dynamic range - preview
Andrew Reid replied to Andrew Reid's topic in Cameras
Nobody complains about dynamic range or image quality off a 1D X JPEG. Certainly not the professional photojournalists, action photographers at the highest level of their sports and every other 1D X user for that matter. Well Canon LOG does wonders for the highlights in comparison... same lens, same exposure (1/50, F2.8, ISO 1600) 1D C JPEG 1D C 4K video with Canon LOG -
Well I don't own an FS7 so for me to name it the best of 2014 would be a bit of a reach. Review coming later in the month if I find time.

In February 2014 I said the 1D C ranked 8th in league 1 along with other cinema cameras (all in the region of $20,000+) Not sure why I put the F5 at 9, maybe I was thinking 4K with the external recorder. Anyway that's the kind of image we're dealing with here. A league 1 hollywood quality image for £5000 is my camera of the year. I don't see what's hard to tolerate or accept about that opinion. It shouldn't really be that controversial. Opinions are always based on needs, perspective and relative judgements which shift over time. Everybody's needs differ as do their opinions, again this shouldn't be the source of so much online bitching and drama. Face to face it doesn't work like this, only on the internet does it become a source of such bitter conflict. Weird! 2 years ago my friend, when the 1D C was released, Canon deserved all the criticism they got from me for pricing regular shooters out of the only major improvement Canon has made to DSLR video quality, since they started the whole democracy. It's not a democracy to them though, it's a business. A bit of a shame if you ask me. It could have been both! Canon on the one hand claim to support indie filmmakers but really they're not interested in art or niches unless they have a massive margin, aka Cinema EOS. Also for the $12,000 launch price 1D C, the lack of video features deserved to be mocked! Not even peaking for that price!? No focus magnification while rolling? Grr! They don't make our life easy considering the money we hand over. However, although these features would have been nice (cough cough) for the $12,000 / £10,000, it really doesn't bother me any more. At £5k as an owner, I am over it. I just want the image and the rock solid reliable 1D X based body, because of the way I intend to use the camera. I will be shooting through a z-finder type loupe handheld off a gorilla pod, no spidery rig or external recorder, no external battery, no shoulder mount and rails, just a small light super-8 style camera that I can go filmmaking with and get the most cinematic image available to me. If you have been an EOSHD reader for a while AccordingToMe you should be educated enough now to make your OWN choices. If the extra video features of the A7S, GH4 and other mirrorless cameras are important to you then you are not short of information are you!? I've been banging on about them all year!!

Lisa Bandy, my last music video in 4K anamorphic :)
Andrew Reid replied to Sebastien Farges's topic in Cameras
Focus is amazingly close with those diopters. Really lovely stuff. I liked the cat eyes, the bed shot with bright window in background and the bokeh / face parts best. Inspiring -
I have always ranked the 1D C's image in the top 10 of all the modern cinema cameras available. This was from nearly 1 year ago - http://www.eoshd.com/2014/02/video-quality-charts-february-2014/ It is a £10,000 camera available now for £5000, in some cases £3500 (James Miller and Dan Chung sold theirs for around that amount). I don't see how this is so upsetting for those browsing for a new camera in 2015. I think it's a total bargain.

Have you tried SLOG 3 on the FS7 yet Oliver? Supposed to be a good improvement!
-
That's ironic coming from Kodak

Yes the D750 is an incredibly impressive stills camera. Really enjoying it with the Sigma 50mm F1.4. Didn't expect the AF to be so good on that lens wide open. Build quality also amazing as is the 'feel' and handling. For video it is definitely 5th though.

Canon 1D C vs Sony A7S 4K - dynamic range - preview
Andrew Reid replied to Andrew Reid's topic in Cameras
GH4 more detailed than the 1D C? It depends where you look! Not in the blacks it isn't! In the end, 4K is 4K if 1:1 sampled. The only thing that can change your perception of sharpness is the micro contrast and digital sharpening applied in-camera. The 1D C Canon LOG has very low micro contrast and virtually no sharpening. Apply that in post and it will match the GH4 for detail. Or you can just shoot with a normal Canon profile like Portrait with sharpness not turned all the way down. Personally I prefer the softer look for 4K. It's enough res already. -
*Sigh*

Yes does seem like a bug in firmware. Can anyone repeat Ivar's fix? Thanks for noting it down, might really help the others out.

Canon 1D C vs Sony A7S 4K - dynamic range - preview
Andrew Reid replied to Andrew Reid's topic in Cameras
Noise reduction in post doesn't give you extra dynamic range JCS or make colour any better, you still need to adjust the curve to put contrast back into the image, thus trading the dynamic range of the flat LOG profile for acceptable colour and contrast. It makes ZERO sense to count the number of stops in a LOG file from a well lit chart. What matters is the quality of colour, tonality, how much detail is in there. When detail is smudged away by noise in the lows, noise reduction isn't going to bring it back. I am aware of that The A7S 4K files aren't tiny at all. ProRes LT is around 350-400Mbit/s compared to 500Mbit/s on the 1D C. The 1080p internal is 50Mbit/s so of course that is going to be smaller isn't it!? Thanks for the tip assistant editor! Haven't you just counteracted your own argument with that then?! Artistically the 1D C looks better and if you can't see that, then you've got, shall we say, "interesting" tastes! Already compared 5D 3 raw dynamic range to 1D C briefly but since this was a year and a half ago, it's a bit hazy in my mind. The 1D C won but can't remember by how much. The 5D 3 shadows in raw get a bit noisy and the highlights clip quite suddenly. They are not a million miles apart though. The advantage of the 1D C is that it works properly, 100% of the time, with smaller file sizes and 4K resolution. -
When a camera like the GH2 or NX1 lacks a flat image profile or LOG gamma, people tend to measure the usable dynamic range from the Rec.709 punchy image it delivers. They shoot a dynamic range test chart and the camera crushes the blacks like it's supposed to, then they go "oh, it lacks dynamic range!" It's such a bad way to test. In reality, LOG is there to be graded. Only once you grade it for acceptable colour and contrast can you see how much dynamic range you have left over. That's the usable dynamic range. The NX1 has no slight aliasing issues compared to the GH2. The GH2 has much more aliasing at 1:1 in the image and it only has at best around 1 quarter of the detail of the NX1's 4K!

Canon 1D C vs Sony A7S 4K - dynamic range - preview
Andrew Reid replied to Andrew Reid's topic in Cameras
Those 14 stops are coming from the sensor, then they are compressed into the LOG image in 8bit. That loses you at least 2-3 stops of USABLE dynamic range OR fucks colour up, depending on how you grade it. To even SEE those 14 stops you have to leave the image flat and measure the chart off that like C5D have done. Who uses that as their final look?! SLOG is there to be graded and those blacks crushed back! If you don't you have horrible ugly contrast and colour and noise in the shadows, not worth it to say you've achieved 14 stops really is it!? 1D C is 12 stops and almost all of it is usable in your grade. If A7S is 14.1 stops like an Arri Amira or Alexa like C5D claim with their flawed testing then I am santa claus. You might be able to get 14 stops out of a test chart with it but 14 stops of usable colour and detail after grading it? NO WAY. If anything it has been scientifically proven in other tests that 14 stops in 8bit LOG is impossible anyway! The bottom and top of the file on the Amira will be golden, lovely colour & accuracy, zero noise. The bottom and top two stops on the A7S are a total mess by comparison but because of C5D's Sony bias they don't mention that. It's the quality of the dynamic range that matters not the fact that SLOG has such a flat image it can see some grey shades in the shadows of a test chart! I would measure the dynamic range of the FINAL graded image and then assess the way it looks artistically. Any NX1 owners around? Try putting contrast -10. You get more dynamic range but it looks shit. Happy with that? No? Thought not -
1D C has gone back up to $12,000 at B&H now, from $9999. So the used prices if you can find one are genuinely a bargain.

Before the GH4, NX1, A7S and Shogun can you remember what we did for 4K on $1500-$2000 interchangeable lens cameras? No neither can I! 2014 has been a great year with some great technology. My top 5 1. The new for 2014 £5000 priced used 1D C! (It's a completely different prospect to what it was at £12,000) 2. A7S & Shogun (£3500) 3. GH4 (£1299) 4. NX1 (£1299) 5. Nikon D750 (£1799) Read the full article

Nice stretch Carl. Come back in a month and see what has transpired. -
Canon 1D C vs Sony A7S 4K - dynamic range - preview
Andrew Reid replied to Andrew Reid's topic in Cameras
jcs I really don't understand your point. Maybe you are indeed arguing with an idiot I can show you stuff... present my findings in black and white... you can deny the evidence and have it your way. It doesn't matter to me. If Canon releases a 5D4 with all the features I want I will be very happy! why wouldn't I!? Turmoil on the forums? eh!? There would be a lot of excitement for it yes. -
I find it madness that people expect people not to ever change their minds. When the NEX 5n came out, I loved it, great little camera. Had it came out yesterday I would have thought - what the hell is this moire ridden thing!? Times change.

I didn't have the 1D C at the time of the A7S review. Not a single one on eBay in 12 months. Had no idea it was about to become available for £5k. And all judgement is relative. The A7S stand-alone is still the "best mirrorless for video" unless you need the internal 4K. I need the internal 4K! That review is of the A7S as a 1080p camera. Now it must be compared with the new NX1 4K internal and how it performs with the Shogun. I wanted the A7S & Shogun image internally, just didn't get on with it as an external box...I couldn't work with the poor visibility of the screen outdoors, the ergonomics of the battery life. Love the image! But not that! If you can't get a 1D C and are considering the A7S then what's different about the review? Nothing. It's only changed for me. The A7S has not. It's the same camera. A used 1D C and it fixed my issues I had with the A7S & Shogun... namely... - Image quality is better - Internal 4K so no need for separate recorder and the ergonomic problems & battery issues that presented - Replaces ALL my other Canon stills cameras for photos - No need to suffer lens adapter bugs - No need to work around colour issues with S-LOG 2 - Avoids bright blue clipping problem - Price was a bargain used considering launch price of 1D C It would be silly for me to get the 1D C if I didn't think it was right for me.

Peaking does work with any lens. The EVF is better for MF as it shows you the actual depth of field. An optical viewfinder is usually F2.8 max.

DigitalEd. What is a quote of Ivar there and what is you? Can you edit it to make it clearer?
-
It shouldn't do though. A camera's sensor and colour processing should be consistent from skin tone to skin tone, light to light, as long as you have it right at the time the shot was taken. In post you should be able to convert LOG to Rec.709 and have the colour looking great over everything, again if it was right at the time of the shoot! What I find with the A7S is that for every different skin type, every different light source, every different location I am losing hours in post correcting for a very narrow and fickle performance window re: colour. This problem went away with the 1D C and Canon's sensor. Under interior practical lights on the A7S I have a yellow cast. Under bright blue lights I have clipping. In low light I have to expose completely differently. In daylight I have issues with purple reds. I never had the same inconsistent behaviour with my old GH2 shooting without LOG in rec.709. To be perfectly honest, it's bloody distracting. And with Blackmagic raw or 5D Mark III Magic Lantern raw video I can apply the same LUT to the whole sequence and it will all look the same and consistent no matter what the light or subject or skin. I hate spending hours on a grade fixing stuff, when it could be spent editing.
