Sony F3 CMOS skew?

[rbilsbor]

Anyone have any details on how fast the CMOS readout is on the F3? I haven't seen any jellocam effects in any of the footage that's out there, but I also haven't seen any whip-pans or any shaky handheld work. Any owners experiment with this yet?

I'd love to see a comparison between the F3 and the Red.

Thanks for the vid! No sooner do I post this than I find this as well:

Jim Jannard has stated that the EPIC has twice as fast a readout as the RED ONE, so while the F3 is certainly much faster than the 5D, you'd think the EPIC (or, more to the point, EPIC-S) will be faster than the F3...

If only that "S" actually existed. It will be a long wait so I look forward to more tests on what is real and costs less than $20k.

Hmmm.

I see some jello in that footage. I come from a film background and therefore do not have a lot of experience shooting video, so I don't have much of a yardstick to measure it against.

To me the F3 obviously does a better job than a DSLR.
But how does it compare to the EX1 etc? I assume it's similar.

It doesn't look any worse than a Red One.

It would be interesting to see some footage of something like an airplane propeller or strobes on an ambulance.

But to me it looks perfectly usable.

The Red MX and F3 skew seem to be in the same ball park.

The RED MX skew is extremely tolerable, that is to say the F3 is as well.

Truth be told, if you getting skew alot of skew on a RED youre panning to fast. 7 second rule.

In MOST situations, sure. But what if you're shooting Saving Private Ryan or, say, Black Swan? The opening scene in Black Swan has some amazing, handheld camerawork. There aren't any whip-pans, but the shake in general -- you don't think these CMOS cameras would skew with shaky handheld camerawork? That's a legitimate stylistic choice in many situations, and that's what I'm wondering about specifically -- not tripod-mounted skew tests, but rather real-world handheld shake.

Well, considering that the F3's skew seems to be more or less on the same level as the Red One, take a look at Gamer and see if the skew in it is acceptable.

Skew is only one artifact of the CMOS rolling shutter; handheld work is usually more susceptible to showing "jello" than "skew". The faster the sensor scans, the milder the jello effect is, all other things being equal.
