Canon 1D mark iv – checked it out

January 24th, 2010

img_5265 So I went to Arri rental the other day cause they had the 1D mk4 in from somebody for an hour.

I took the chance to squeeze some footage out of the baby and do the basics test we’re usually missing on those photo review sites.

I really lost track on wether the mk4 is out yet or not. Mine is still on hold, I ordered it last year. Anybody know?

I did a short rolling shutter video and checked out hdmi and menu settings:

Ok, keep in mind I had one hour, I did all this really quickly.

trying to test moiré:

(moiré is the coloured effect that appears on hard contrasted hairlines. Basically it sucks and we don’t wan it.)

This is a 100% screenshot of a video shot with a Zeiss 28mm 2.8 @ 4.0 in both cases. I had a shutter of 50 at ISO200. The problem you see is that this footage isn’t good for comparing moiré. The test objects would need to have the same size, sorry people. The sensor size difference makes the 1D footage wider than the 7D.

Unfortunately I think the 7D also had different user settings than the 1D. I think I had the 1D lens pretty sharp but the image looks blurred compared to the 7D. I cannot say wether a different user setting would have resulted in the same amount of moiré or not. What we see is that there IS moiré in the 1D footage. I tried to film hair, but it wouldn’t moiré at all. Sorry.

With a different user setting it is hard to say anything at all about the footage. I should have thought about that before. I think I have noticed a better dynamic range and cleaner quality though.

trying to test rolling shutter:

(rolling shutter is the effect that appears on fast moving objects. They get squeezed. Less is obviously better)

I’d say it’s slightly better, not removed AT ALL.

That was a video shot at first at shutter 200, later shutter 50. Zeiss 50mm @ 4.0.

Bitrate is the same at around 50 mbit/s

Then I tried the hdmi output. Unfortunately everything is very much the same as on the 7D. Same output, same size, same size while recording, no lcd while hdmi connected and no lcd while video is connected. Why Canon why???

Also checked all menu settings, like ALL of them, there’s nothing that would turn the lcd on during hdmi or video out.

I almost forgot: Did you know that the 1D is so high rails can’t go underneath it? That means to use a shoulder mount or ever extend / retract rods is impossible unless the companies come up with a whole new design dedicated to this cam.

What’s the conclusion? For me that is: If you need the better low light performance and wanna spend 3000 additional €uros or dollars or whatever your currency is on that. Ok. But apart from that not much has changed. I’d say there’s slightly better picture, slightly better dynamic range (guess), slightly better rolling shutter performance, slightly bigger sensor. But the 7D will do almost as good.

Cheers,

Sebastian

Nice, a 7D with BNC mount:

Syndicate Entertainment remakes the 1D so it has both PL mount and Arri rods. i.e 19mm rods in arri standard possition. since the Syndicate mount is clamping onto the mount the camera sice does not matther much.

Best regards,

That’s interesting that you say you CAN’T put rails under it… Redrock (and probably other vendors) make rigs that accommodate battery grips, which would essentially be what the 1D Mark IV has built into it.

Can you explain further? I don’t understand what you mean.

Thanks for taking the time out to give us a comparison test regardless of time frame! Thanks man

I was wondering if the video settings changed one bit, as in would we still be required to use the same flat video settings as we do on the 7D for quality maximization?

Thanks

why is it that you get only one hour with a camera and provide more useful information, than some people who have the camera waaaay before release?

Presumably you were using the Arri rod support? This can be adjustable to take into consideration the added height of the 1d base? This doesn’t get discussed much, but I would imagine many people could find a PITA.

Keep it up
cheers
