Canon 5D Mark III dSLR
introduction
announced March 2012, the Mark III represents nearly everything Mark II owners wished their camera had:
very sensibly, Canon decided against following the lead of the Nikon D800's 36mp sensor, and instead opted for what is probably a better compromise - a 22mp sensor with presumably better high ISO performance and better dynamic range
nevertheless, consumers and pros may still decide the 36mp Nikon D800 is their preferred camera.
interestingly, Canon also announced their 1st radio remote TTL flash transmitter and new RT flash.
potential show stoppers
flash sync only 1/200th sec - not great for strobists, fashion photographers or wedding photographers working outdoors
no AF at f/8 - not great for wildlife photographers wanting to shoot f/4 telephoto lenses with a 2x teleconverter
poor image detail in HD video

specifications
weatherproofed body based on a Canon 7D design
22mp full frame sensor with 8-channel sensor readout enables continuous shooting at 6 fps
supports radio remote TTL flash (need the new Canon 600EX-RT flash and the WT-E3-RT wireless transmitter) which now allows up to 15 flashes in 5 groups
no built-in flash
a major disappontment is the reduction of flash sync to only 1/200th sec
ISO 100-25600 standard, 50-102,800 expanded and autoISO can be given an upper and lower range as well as setting a minimum shutter speed (1/250th - 1 sec only, bad luck if you are a sports photographer who wants 1/500th sec and wants to avoid Shutter Priority metering)
Shutter rated to 150,000 frames and has range of 30sec -1/8000th sec
1D X's “silent” shutter mode, allowing it to shoot in both single images and continuously (at 3fps) with greatly reduced shutter and mirror noise
100% viewfinder coverage
-
Dual card slots for CF and SD supporting SDHC/SDXC and Eye-Fi wireless cards
61 point AF system (41 of them are cross-type points and, uniquely to this sensor, 5 of them are diagonally sensitive) and new menu system as in the
Canon 1D X sports dSLR but doesn't have the 1D X's 100,000 pixel metering sensor to gain tracking information from, nor a dedicated DIGIC 4 processor to make sense of it all.
disappointingly, like the
Canon 1D X sports dSLR, the cross-type points can only be used with lenses that are F4 or brighter (and the double-crosses with F2.8 and brighter lenses) and worse, you cannot AF at all using f/8 (ie. when using a 2x converter with an f/4 lens which will disappoint many wildlife photographers)
63 zone iFCL metering system
DIGIC 5+ processor
in-camera HDR shooting mode and HDR bracketing up to 7 frames covering a +/- 8 EV range
exposure compensation +/- 5EV
multiple exposures
electronic levels display in viewfinder and LCD
AF Microadjustment now allows programming BOTH ends of a zoom lens range
automatic vignetting and chromatic aberration correction in jpegs, based on lens profiles which are stored in-camera but obviously only works on Canon lenses and most Canon users would not bother using in-camera jpegs anyway (this in not an Olympus jpeg engine) and would prefer to process RAW files
USB 2.0
mini HDMI out but no live video out?
optional BG-E11 vertical grip with extra battery
optional GP-E2 unit for GPS
optional WFT-E7 wireless transmitter unit
N3 type remote control cable outlet which allows timelapse recording via PC or cabled remote device
950g
152 x 116 x 76 mm (5.98 x 4.57 x 2.99“)
HD video capabilities
1080 30/25/24p H.264 but in reality, vertical resolution only seems to be 720p
720 60/50p
VGA 30/25 fps
All-I and IPB interframe compression options:
All-I: each frame is treated independently, rather than trying to identify and compress common areas for neighboring frames
IPB interframe: 4x file size thus 22minutes will require 64Gb
moire-correction during recording
SMPTE timecode recording (Rec-Run and Free-Run)
less rolling shutter than with the 5D Mark II
built-in headphone socket for audio monitoring, and rear control dial now has touch-sensitive 'buttons' that allow recording parameters (shutter speed, apertire, ISO and sound volume) to be changed silently
mono microphone

for a nice real world comparison of HD video capabilities of D800 vs Canon 5D Mark III, see
Dan Chung's review here
uses Level 5.1 H.264 encoding so to get the best results using Adobe Premiere, change from Adobe's default H.264 Level 4.2 encoder to Level 5.1 which gives far better colour, tonality, contrast, less noise and less macro blocking
2)
Firmware version 1.2.1 (May 2013) allows uncompressed 8-bit 4:2:2 video output with time code over the HDMI port. Uncompressed video can be output while the video feed is simultaneously displayed via the rear LCD panel and recorded to the camera's CF/SD cards.
