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).

Canon 85mm f1.8 vs Nikon 85mm f1.8: A lens-battle

Image credits: Chris Gampat

This is from a post by our friend Chris Gampat over at thephoblographer.

He used a Nikon D700 with the new Nikon AF-S 85mm f/1.8G and a Canon EOS 5D Mark II with the EF 85mm f/1.8 USM. It’s not a comparison between cameras but among lenses. As Chris writes:

[…] I decided to put the two lenses in a non-scientific and totally practical test using all available light at around 7pm in NYC and only shooting at f4 and wider for a portrait.

Regarding ergonomics, Chris says that

Both lenses focus extremely fast, though in real life practice I felt that Canon’s 85mm f1.8 is still the current champ. Indeed, it has often been touted as the company’s fastest focusing lens. A known problem with it though is the color fringing wide open; but this is also a problem that plague’s Nikon’s optics […]

Note that Canon’s EF 85mm f/1.8 dates back to the times when we were using film-cameras, and that Nikon’s 85mm f/1.8 is a rather new lens.

The test-shots where made during the golden hour, using ISO 800 on both cameras:

I set both cameras to aperture priority and focused on the same spot of Dennis’s eye. Though their meter readings were very slightly off in aperture priority, it should be noted that in general, Canon and Nikon do have slightly different metering algorithms and this is just part of how they work.

He shot using the aperture range from f/1.8 to f/4. I post some of the test pics shot by Chris. Please visit his site and read the post to get the whole picture (and to see the test images at higher resolution).

First two shots at f/1.8, Nikon’s 85mm on the left and Canon’s 85mm on the right side (image credits: C. Gampat)

 

 

Next two shots, at f/4, Nikon on the left, Canon on the right side

  

 

All pics were shot in aperture priority mode. You can see that the images shot with the 5D Mark II are little bit darker (it is known that Canon cameras tend to underexposure). Also, to me the bokeh obtained from the Nikon lens looks better (but I probably shouldn’t say that :-) )

The discussion is going on. Join it in the comment section of Chris’ post (where you will find more information by Chris itself).
