Canon finally releases the latest mid-size full frame DSLR: the Canon 5D Mark III.
Nowadays the upgrade of a camera normally takes less than those in the past. 5D Mark III is not particularly too long when you compare it with age old models such as 5D Mark I or the latest Nikon D3X.  There is also no X version, so Mark III is truly a Mark III.  Canon does not do any trick by removing the anti-aliasing filter before the sensor like Leica M9.
Thanks to Bob Atkins who in his 5D Mark III review concludes that this is a nature of incremental progress.
Yes, it is a progress made in nearly all aspects but not in the sensor size.  It is still 22 MP CMOS.  In terms of the growth of sensor size, it is almost none (5D Mark II is 21.2MP).  Nikon D800 has already reached 36MP.  So what is the logic behind Canon 5D Mark III?  How does it compare with Nikon D800?
The dilemma of Canon Mark III is the response from the clients.  Canon has the capability of making a 36MP.  But who needs a 36MP? If everyone is happy with the 22MP, the provision of larger megapixel will be another realm, meeting the demand of larger print.
Canon flagship 1DX and Nikon D4 are all with a CMOS sensor of 18MP.   The ‘X’ factor is now on the sensor sensitivity range:  the ability to capture with low noise in low light situation.  From the specification and some previews, 5D Mark III is already following the X tradition: improved metering, better autofocus, faster continuous shooting, up to ISO102,400 light sensitivity and 29 minutes 59 seconds video clip length and bigger LCD monitor size. If you are a fan of Canon 5D video capability, this is a camera that won’t disappoint you. At the back of the camera, the command dial, joystick and other controls are placed in easy accessible positions to give a peace of mind.  Not to mention the video quality.  Don’t forget some TV episodes were already taken from a 5D Mark II body.  So the expectation of an improvement in video quality is well understood.
Would I buy a 5D Mark III? I can’t tell given the introductory price is US$3499, $550 higher than a Nikon D800.  As usual, the right time will be till some tests are done by major camera review sites.  Or the price will be reduced slightly after a certain amount of supply. At the moment it seems the results are positive, even at ISO102,400, the jpeg image is decent and clean. 5D Mark III always has a wow factor because its sensor is full framed:  a 50mm lens is a 50mm lens, no need to calculate the cropped size.
Canon 5D Mark III offers an answer to those who have been waiting for such a long time for an upgrade.  But it is not an overall satisfaction because Canon does not beat Nikon in the sensor pixel.  I do not know what Canon has in mind, given the fact that it is not a difficulty for Canon to produce a CMOS sensor in larger pixel. The reason is more about marketing than improvement.  Certainly there is a gap that Canon may wish to fill up: the rumoured Canon 3D or a mirrorless.
