eos 7d - rolling shutter - hard - DVXuser.com -- The online community for filmmaking

Hey there, i got my 7d just today.
Shot a couple of images.
I realized there is a HARD rolling shutter on every movement.
ok i held the camera in my hand, but look here

i just laughed a bit at this shot, so its shaky, and there you can see the rolling shutter.

is this normal? or could my sensor be damaged or something like that?

can a faster CF card improve the problem?

lense was 50 mm ef 1.8

It's normal. Handheld with these cameras only works with practice and concentration. I was disappointed too when I got mine, but after shooting for a month I've gotten to the point where the footage is useable in handheld mode...

Also, a wider lens helps a LOT.

Your camera is operating exactly like every other one. You can't do shaky handheld shots like that with a rolling shutter camera, or you'll get the results you got.

So turn on the lens's stabilization, and get a handheld rig, and use a wider angle lens, etc... there are lots of ways to address it, but there's nothing wrong with your camera and no, a faster card wouldn't have any effect.

Are you using a IS lens it helps ssssoooooooooooooooo much... all I do is shoot handheld... until my shoulder rig is finished.

That nifty fifty lens is way too telephoto on the 7d to shoot hand held with. Get a wider IS lens if your strictly handheld.

Or weigh it down.

I did two 3 minute handheld interviews with the nifty fifty came out real good.
Tighten the strap around your neck ( dont kill yourself and ) and shoot .

You know a good thingto have like with any other camera is to purchase a stable tripod !

They don't overcome it. It has all the same issues. All the CMOS cameras do. Some are worse than others (like the HV20) but all the same issues remain.

Shoot with the red in 4K at a still shot shake it in post or do smooth moves with electronic cranes and jibs
