I go to college in Philadelphia but from Florida actually. But wow thanks for the offer!  ;D


The 6D has arrived in FL but it would be a little over a week before I'll actually get to touch it! As I've never explored video before, definitely am interested.

As for my username, I was first introduced to football in high school by a die-hard Saints fan and one of the first games I watched was a Packers game. I was supposed to be rooting for them because it would somehow help the Saints move up. Anyways then came that fateful Super Bowl day. my friend wanted me to root for the Steelers but I refused. We even bet on it! and you know how the story ends.  ;D

Doesn't matter why you wear the crown of cheese,
Green blood in the Florida sun will never freeze

I am sure you will like your 6d, its really good at high iso  and you have a 70-200ii that lens shines on a full frame body

All of the serious videographers seem to manual focus? Maybe you can try magic lantern which I understand has focus peaking that gives you a clear look at where your focus is.

6D user here!

ML with focus peaking is a big help, however there are audio recording problems.


Also, since the 6D doesn't have the AA filter there is tons of moire. Honestly, it makes a lot of footage look like crap  :-\

Unfortunately, you're wrong - the 6d does have an aa filter that also makes still shots softer, the moire is the result that downscaling to hd resolution cannot use "pixel binning" like on the 22mp 5d3 but needs to interpolate some of the 20mp lines - and the 6d is very bad at doing this.

I thought the 6D did not have the AA filter?  ???

Can you send me a link/article?

im new in taking video using dslr.

i got a 6D.
How about auto exposure. from darker scene to brighter scene or vice versa.
Does 6D or other dslr got this feature?

I never heard anyone mentions about this.

Thanks.

You can set the ISO to auto and everything else manual. I don't recommend full auto mode since the camera will often guess wrong.

They could just as easily do exact pixel binning on the 6D.  They would just have to crop the image first.

  • At 720p, the sensor is 4.275 pixels per output pixel, so you could throw away the outer pixels (use a 1.07x crop factor) and then scale 4:1.
  • At 1080p, that approach would be more problematic, because the ratio is 2.85:1.  Making it 2:1 would be a 1.43x crop factor, making it almost like shooting video on a crop body in terms of what it does to your field of view, but it still might be worth it if the results had less moirĂ©.

With that said, it isn't just a question of binning.  If you just bin a bunch of pixels together, you'll get more moirĂ©, not less.  You have to do the binning in combination with a digital low-pass filter that effectively does the low-res video equivalent of what the antialiasing filter does for stills.  The real question is whether the 6D has the CPU power to do the low-pass filtering.  If it doesn't, then binning won't help.  And if it does, then someone could probably come up with a better algorithm for non-integer downsampling than whatever the 6D currently uses, resulting in video that is comparable to what you'd get with binning, but without the field-of-view change.
