5D3 Photographic Dynamic Range etc.
Mar 9, 2012

This is my first post in any dpreview Canon forum.

I think the information will be of interest to certain people but certainly not to everyone.
I consider my testing methodology to be objective.
So please don't "shoot the messenger" if you don't like the results.

That said, I have far more experience testing Nikon cameras than Canon so errors with the Canon measurements are slightly more likely than for Nikon.

The testing methodologies are pretty standard and are outlined at my site, primarily in the Sensor Analysis Primer.( http://home.comcast.net/~NikonD70/GeneralTopics/Sensors_&_Raw/Sensor_Analysis_Primer/Sensor_Analysis_Primer.htm )

If you're not familiar with Photographic Dynamic Range (PDR) it is analogous to DxOMark Landscape DR but with different normalization criteria.

I have just processed the Imaging Resource CR2 files for the EOS 5D Mark III.
Most people find my Photographic Dynamic Range Chart the best overview:
( http://home.comcast.net/~NikonD70/Charts/PDR.htm )
A good cross section for comparing cameras is this bar chart:
( http://home.comcast.net/~NikonD70/Charts/PDR_65.htm )
More technical information would include read noise:
( http://home.comcast.net/~NikonD70/Charts/RN_ADU.htm )
And a restatement of PDR that shows how shadow DR improves with ISO:
( http://home.comcast.net/~NikonD70/Charts/PDR_Shadow.htm )

Click on the model name in the chart legend to select and deselect the cameras to display.

You can see that the 5D Mark III compares favorably with the top Nikon models in PDR.

I will be adding 5D Mark II data that I already have shortly. The Mark III is similar to the Mark II at low ISO and shows slight improvement at high ISO.

Finally, if you would like to contribute Canon data for analysis then please contact me by email.

Regards
