Rolling shutter jello comparison: 5D Mark III vs Sony Nex 7

Photographer Mike Kobal did an interesting test using a EOS 5D Mark III and Sony’s NEX 7 to demonstrate the rolling shutter effect. Mike’s premise:

Keep in mind this is an extreme test to demonstrate the rolling shutter effect, no one in their right mind would pan like this. However, there are plenty of real life situations when the jello effect suddenly becomes a problem, a fast train or car passing will have leaning windows and elliptical wheels, or watching a chase scene with moving camera and subjects will make you dizzy. Until we get global shutters, the jello effect is CMOS sensor’s biggest Achilles Heel.

If you never heard about the rolling shutter effect, the short video that follows will give you an idea. Otherwise jump over and read on.

You may wonder why two cameras not in the same league are compared. It makes sense, since theoretically the Nex 7 should perform better because of its smaller APSC sensor (the rolling shutter effect increases with sensor size).  The EOS 5D Mark III was set to 1080/24P, ISO 100, Shutter Speed 1/50th, F/8, white balance 5600K, Picture Style Neutral. The NEX 7 to  1080/24P, ISO 100, Shutter Speed 1/50, F/8, Picture style Portrait. Sharpening, contrast, saturation have been turned down to zero on both cameras.

Let us first have a look at Mike’s video:

The weird thing is that the EOS 5D Mark III performs better that the Sony NEX 7, which is surprising to some degree. Mike writes:

Surprise, the 5D3 kicks Nex 7′s gluteus maximus, I sure didn’t expect that from the FF sensor, either the Canon is very good or the Sony just terrible, your pick :) !

If you have a look at the crops below you can clearly see that the NEX 7 produces more moire than the EOS 5D Mark III

Yeah, what shall I say? Maybe that the EOS 5D Mark III is a great great camera? :-)

There are much more test pictures and crops you can analyze in Mike’s post (which is absolutely worth to be read: click here).

BTW, Mike has also a post about his brand new EOS 5D Mark III (click here) and provided us a nice unpacking video:
