Now Available! OWC 960GB Mercury Electra™ MAX 3G SSD 2.5″ Serial-ATA 9.5mm Solid State Drive

OWC is now selling 960GB SSD drives. We’ve been using them (smaller sizes) for the last year or so, in both single drive and dual RAID 0 configurations. Big improvement over normal 3.5″ SATA hard drives. They are not cheap but if you need the speed they are well worth it.

See specs below from their website http://www.macsales.com

Canon 5D Mark III Test – ISO

1/60 sec, f/4, iso 800, Canon 24-105mm

 

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.
