The new Canon 5D Mark III showed up recently. So far so good. The following items are improved, AF,  frames per second, audio capability, high ISO performance, construction/weather seals, LCD screen, etc.

For the first round of tests we have some in studio ISO samples. ISO 100-12800, 50mm Canon f/1.2 L lens (focused with live view on the rodenstock loupe), processed in Lightroom 4.1. Full Res JPEGs with default sharpening applied, no other tweaks.

I decided to do a print test on our big Epson with an ISO 3200 file.  The native file size @ 180ppi gives us about a 21″ x 33″ print.  No interpolation. After a little adjustment on the Luminance in Noise Reduction in Lightroom  and some sharpening, I made a print.

What the print revealed was that with proper technique, good optics, etc. a beautiful large print can be produced from the Mark III even at ISO 3200 to 6400. There was just a slight “grain” look at ISO 3200, and a little “grainier” at 6400.  But, overall it exceeded my expectations.
