Canon 5D mkIV Crop Factor Reduction

To be honest, I think each person has the right to re-evaluate his next camera purchase, certainly GH5 was the only option just a month ago for many people, since there was nothing similar in the market, but now with the new Canon rumors, if at least part of them are true, like crop reduction and C-log, 5dmkiv could be really a good option for a lot of people, and certainly most of these people will not have the option to purchase both systems, therefore a delay in their purchase decision until real information is available is a logical step in order to spend their money in the system which better fit their shooting style.

If it was true (which I'm 99% sure it's not), we would probably see a new "worst rolling shutter" champion, dethroning the a6300. The 5D iv has quite bad RS, reading out even more of the sensor will make it even worse.

Also how would they suddenly manage downscaling and and XF-AFC (does that mean XF-AVC I guess?) with the same processors and encoders that only managed 1:1 read out and MJPEG so far? Not even the C700 can downscale but uses windowed mode if you use a resolution but full sensor raw and that thing is huge, expensive and has active cooling. Which is the last point: "installing a new heat sink". Like what? Do you think Canon left a huge empty space in the 5D iv body just so eventually a year down the line they can install a bigger heat sink?

Sounds completely fabricated. Manufacturers don't run their product at 60% performance to then suddenly go "surprise mofos! We got a firmware update that makes everything so much better!". If this was Fuji, well maaaaybe, but Canon? Did they ever bring anything meaningful in a fw update except the one to extend the 7D sales cycle?

Rolling shutter will not get worse. There is a hard limit on how bad it can be due to the need to start the next frame, which for 30p is about 33 ms. The sensor of the 5D4 is likely being fully read anyway, but only some of the data is actually used since the limitation is heat generated by the processor. Less data = less heat.

The 5D4 can't do H.264 encoding for 4K since it has the wrong processor for that. It would need a Digic 7 to do that in hardware, and doing it in software would be too much for the processor.

There won't be space for a bigger heatsink, nor is a fan practical. The camera's body is the heatsink. The only thing they could do to improve the thermal envelope perhaps would be to replace some of the materials inside the camera with stuff that has better thermal conductivity. More likely the servicing is to disable or replace the internal sensors that trigger the overheating warnings.

That CDAF is distracting. Put Canon's Dual Pixel or Sony's a6500 quality PDAF in there and the GH5 would check all my boxes.

if any of this is true – that canon is making uncharacteristic radical moves to 'fix' the 5d4 for video – they should enable a raw mode on the 1dx2 with those cfast2 cards. no overheating! just dump that raw data baby!!!! 😀

Replicants will be running amok first.

The info from this rumor comes from a new source.  That means any one of us cunts could have written it. Its not even worth discussing!

True. But considering the length and details about the rumor, it's hard to imagine that a fucker would have such a sucking life that he would do that for fun.

Don't underestimate the human race! Especially so close to april fools day.

hmmmm, maybe this is an april fools that got leaked early?

I've got a new rumour from a credible Canon source that said; Canon are going to implement Raw video via firmware update to mitigate over heating issues and drive up sales of 5D. 

It's practically confirmed FYI.

Send it to Canon Rumors and see if they post it, oh wait...

Of course it could be put out by a company (not Canon) that may have a GH5 killer camera coming that isn't quite ready yet.

That way, people hold off buying the GH5, get annoyed with Canon and then everyone migrates to the new flavour of the month.

Or it could actually be true but that remains to be seen.

For me the GH5 is in a different market segment for the most part to a 5Div.
