  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

CANON 5D-MKII - There is NO SKEW (not much)

This is seriously non-judgeable from this youtube vid.

I should say it is, as far as skew goes: you can see that there is not any severe bending going on. The video is actually a good example of how holding a video-dslr makes you suddenly the shakiest camera operator in the world. I have a d90 and without support it is very challenging to hold still.
 
I'd expect very much that it looks like the live-view on the 1D(s) MK III, which is quite visible. There's quite a jitteryness to that footage that looks nasty, although not quite as nasty as D90. Next test is to see a zone plate to see about aliasing. The quicktimes on dpreview look "ok", but very over-sharpened.
 
Don't know if it's youtube or the cam. We will see as soon it hits the store. There are hopefully a lot redusers that will mount this thing on rails and a tripod I hope.
 
The big advantage is handheld for a DSLR because most people using it will use it hand held. That's why skew is a big concern for me.
 
I don't think a DSRL formfactor will serve any good for shooting professional news stuff out of your hands. Skew or not, it won't look great anyway.
 
From the afore-mentioned clip the amount of skew is not hideously gigantic, however there is a detectible (rolling shutter) mild skew. That would kill it right there for a lot of applications as compared a digital global shutter.

Never the less, what I would like to know, if the camera is locked steady, and the subject such as figure walking into the frame, or a static close up on a person’s face (talking/ dialog) would you see mild skew?

I.e. would you see detectable skew on a person’s face. That girl on the bridge seemed to be moving and animating herself awfully slowly…
 
I think the clips shown thus far from Canon are cleverly designed to hide skew.

The sequence of the cars through the mirage of hot tarmac (asphalt) hides skew rather well. The sequence with the squirrel is rather clever as squirrels tend to be still then execute a quick move or two and then are still again, so the animation results in still, blur, still etc. the fast movement blur hides the skew; same for the bird. The girl on the bridge and the street seems to stand very still, and when she moves, she moves very slowly, when she animates her face it is either quick or very slow transitions, nothing in between. Also obviously camera is locked absolutely still. These are all skew hiding techniques and I bet that Canon had tons of clips that they couldn’t show because of rolling shutter artifacts.

Oh well back to reality then...

How much perfection do you need for $2700? They give you a compact DSLR that you can hide in your pocket, take 21MP stills and shoot excellent videos with 35 mm DOf on a full frame sensor, interchangeable lens, and SD card recording, stereo sound. You can sit here and criticize all day long, but people are calling in orders with dealers for future delivery.
Our dealer says, Sony is bringing out the 28MP still/video camera without skew, for the same price.

I've made very similar points on other threads, and you make a good point. Our primary interest in the 5D MII is for 3d capture techniques with our software. Currently we are engineering for RED one and also Leaf Digital backs. For an eight camera set up this get v.expensive. We are very interested in the 5D for these reasons of demonstrating the utility of camera that can do double duty. The DSMC, if its everything Jim claims it to be, it would be a fantastic fit for us.

However the 5D for stills would be great. The 5D for stills and dynamic (for 3d capture) would be no good if the subject to be imaged has its head and shoulders leave the frame first and then their pants follow some time later that would be a problem. We are fairly flexible on the other critera.

Does the 28MP Sony camera really do video? Do you have a link for that?

Cheers,
