    Hey if Phillip bloom can do it with the Fx9, right? Funny, My girlfriend had been listening to me go on about this camera since launch, so I thought I'd try to get some shots of her kittens the first day as a present. They were having nothing of it. I'll need to try again.

    Ha...well if you keep pushing any image it will eventually fall apart...here's that image pushed another stop or two...actualy I'm a little surprised at how little it's breaking up given where it started...but there's a streak! (hard to see with DVXUser ProGamma applied). Still, it's totally, absolutely normal.

    I should mention also - that I downloaded the test low light footage that Cinema5d posted here: https://www.cinema5d.com/canon-c500-...clip-download/ - And was not able to replicate the streaking. There were definitely some underexposed areas in those shots.

    Well Barry you did achieve some streaks- especially on the cats (looks kind organic lol; j/k)!

    In all seriousness, I'm sure those seeing this issue appreciate your effort to help solve. While you did surface some streaks with a bit of effort, it's fairly subtle compared to the other examples? It seems that the issue is strongest when there's very bright and very dark elements in a shot at the same time (high/max DR) and then the shadows are pulled up significantly in post.

    Perhaps you guys can set up a similar test, with at least one clipping level light source and do the same tests on all the cameras, then compare results (Ideally you'd test in the exact same conditions). Perhaps use fixed ISO, F, shutter, peak brightness in scene (as shown on camera meter(s)), etc., then share footage.

    Actually I'm well acquainted with that footage, having produced the alternative grade of it that is posted in the comments of that site. So that footage is different than your case...all shot at higher ISO (something you'll remember I suggested as an option for you), and it's XFAVC, which means it should have less noise, and I think, given the subject matter is generally exposed rather well. There are two shots though, at the very end that are underexposed quite a bit. Increase the gain on them, and you will find various forms of streaking, some from smear, others are pattern noise. Nothing to write home about. The LUT, as always, tells all, those areas "should" be black based on where they are exposed.

    Phil shoots his cats with every camera he gets. I think one of the cats is even named 1D C. For unknown reasons.

    If you want to keep the poster's screen name in it, copy and paste it with the post reference after it. There's probably some other way to do this but I haven't figured it out yet.

    My first assisting job was for a photographer with a Jack Russell named Kodak (who replaced a previous model named Ilford), and a cockatoo named Agfa. Which tells you just about how old I am.

    Agfa (Aktiengesellschaft für Anilinfabrikation) was started in 1867 by the son of Felix Mendelsohn and a partner. During the 1920's, it was taken over by a united chemical conglomerate known as IG Farben (Interessengemeinschaft Farbenindustrie AG), effectively a state controlled cartel of BASF, Beyer, Hoechst, Agfa and others. Arguably, the 1930's Agfa color film was superior to any of its competitors and the German WWII color photos were of higher quality than any of the Allies (which were mosly in black and white anyway). After the war, Agfa film patents were appropriated as "compensation".

    BASF/AEG reel-to-reel tape recorder (Magnetophon) was similarly exported. It was then modded by Ampex in the US as Ampex20a and changed the face of radio.

    Not a professional historian. Just play one on DVXU.

    Yes I've seen that Xyla chart before Barry. What you are showing is not the whole picture though. The original below shows three cameras were compared and the third one was the C300 Mark II where you see broad band dark streaking starting to appear at least 1.5 to 2.5 stops prior to the end of the red line denoting usable range. Worse than the FS7 even. I just hope the 500 II is not going to exhibit the low end streaking that quite a few C300 Mark II users have mentioned. Time will tell I guess.
