Canon tops range with 1080p-ready EOS 1D Mark IV

EOS 1D Mark IV adds 16MP, ISO 102,400

Canon tonight finished its last major DSLR update of the past year and launched the EOS 1D Mark IV as its highest-end camera. The new model jumps from a 10-megapixel APS-H (near full-frame) sensor to a 16-megapixel, 1.3X crop unit and upgrades to twin DIGIC IV processors. The boost gives it 1080p video at 30 frames per second, or 720p at 60 frames per second, while still shooting full-quality still images at up to 10 frames per second. It can also match the Nikon D3s' ISO 102,400 light sensitivity and so can shoot in extremely low light without invoking flash.

An overhauled 45-point autofocusing system is new and, like with the EOS 7D, can automatically group points together to speed up selecting the right area while still allowing the camera to focus on a more exact point. It can also track a subject locked in one point across any of the other points, even if it's temporarily blocked.

Image quality should be improved with better noise reduction as the image leaves the sensor; 14-bit color conversion now occurs even at the maximum 10FPS photo shooting rate. A coating on the low pass filter should remove more dust from the sensor than in the past, and photographers can now capture smaller S-RAW or M-RAW shots to shoot faster or at reduced file size without losing compression.

The EOS 1D Mark IV arrives in a body-only kit at the very end of the year, in late December, and should cost $5,000. A companion add-on, the WFT-E2 II A, will give the Mark IV 802.11g Wi-Fi and Ethernet support to share photos over local networks and the Internet, including remote shooting with a live preview; Bluetooth is onboard to add geotagging with a wireless GPS receiver.

    5K for a 1.3x Crop Sensor DSLR

    Not crazy about 1.3x crop sensor for 5K, but anyway, what lenses do you use for this? Full-frame lenses? I imagine the crop-frame lenses don't fit? 102,400 ISO? Can't imagine the image quality is going to match Nikon's D3s.

    I'm Sold!

    Don't care I rather Canon than Nikon! This will go great with a New Apple MacBook Pro if they announce it tomorrow!

    I'm Not Sold!

    I'm agnostic, but I don't care what features it's trying to match against NIkon... if it ain't full frame, I ain't buying it. Seems like Canon is playing me-too with bodies a bit too late over the last few years. Not saying I'd switch to Nikon if I had a bunch of Canon gear, but I certainly am not tempted to switch TO Canon.

    Looking like D700S in my stocking this year. (hear that, Santa, you fat f***?)

    Uh Oh it's APS-H Sensor!

    How in the world can Canon make a EOS 1D Mark IV and not be full frame but APS-H again? Just like from EOS 1D Mark III.

    "16.1 Megapixel APS-H CMOS sensor and Dual DIGIC 4 Image Processors for high image quality and speed."

    OK, is it that bad?

    Megahertz Myth...

    It's beginning to appear that like the "megahertz myth" during the "processor wars", the megapixel myth is starting to expire also. Consumer compacts appear to be stabilizing around the 10-12MP mark with extremely small dense sensors and the pros are getting the 14-18MP puppies on a larger (but not full-frame) sensor. In truth, people need to realize what an enormous piece of silicon a full-frame sensor actually is, with lower yields and higher cost. Just look at the price of "medium format" devices. Halving the size of the sensor quadruples the yield or quarters the price... a no brainer. Or, lowering the density and increasing the pixel size improves sensitivity and reduces noise... another no brainer. The fundamentally illogical (if not nonetheless attractive) notion that sensors should have aspired to the same dimensions as an unconstrained piece of film is sliding into the mists of time just like the idea that people should pay for content. It's a brave new world!
