Phase One has released a digital camera back with a 39-megapixel sensor for medium- and large-format photography. The P 45 has a capture rate of 35 frames per minute, a write speed of up to 20 MB per second and 117 MB per file size capability.

The P 45 digital camera back also includes Phase One’s revolutionary secure storage system (3S) technology. The 3S technology eliminates the risk of writing to damaged storage media by first checking the validity of every CompactFlash storage card inserted in the camera back.

Using Capture One software with the P 45 allows professional commercial photographers to capture, adjust, prepare for print, and archive images quickly. Increased efficiency decreases the amount of time spent in postproduction.

The P45 is $32,900, which includes a three-year, value-added warranty.
