Canon has only just announced the new EOS 1D Mark IV, but that hasn't stopped us from having a brief play with the new camera when it made a quick pit stop in New York City on Friday at the PDN PhotoPlus conference.

The big, and we mean big, new camera is described by Canon as "a high-speed, professional digital SLR designed to empower photographers to capture split-second moments in high resolution, under the most challenging of conditions".  

What that means is that you to get a 16.1-megapixel APS-H CMOS sensor as well as a new, advanced 45-point auto focus system with dual "DIGIC 4" processors, allowing for shooting of high-res pics at up to 10 frames per second. This is backed up with the widest ISO range ever to feature in a Canon camera with extended ISO ranges from a low of 50 to 102,400.

The new DSLR is robust and weatherproof with a full magnesium alloy body, can capture 1080p high definition video at 30, 25 and 24fps and 720p footage at 60 and 50fps.

There's a 3-inch Live View LCD display, revamped buttons and updated picture styles while the EOS 1D MARK IV is compatible with all existing EOS 1D Mark III accessories, EF lenses and EX Series Speedlite flash units.

In the hand and its an impressive piece of kit, which was quick to respond, and those two memory card slots (SD and CompactFlash) can be set to receive images in a variety of ways including jpegs on one and raw on the other, as a RAID solution (ie to both at the same time) in tandem and more. 

We were sneaky enough to slip in a Compact Flash card and shoot some pictures, however it seems we needn't have bothered as no software application we have in Pocket-lint towers (Adobe Lightroom, Photoshop, and Canon's own professional RAW manager) will allow us to open the files. Doh!

We will add the test shots in as soon as our software lets us open them.

The EOS 1D Mark IV is due to be available from the end of December 2009 priced at £4499.00 or 5499.00 euros.
