The first time you touch you feel a little reinforcement with rubber pads. I can not say that this is much better quality than those of its predecessor, only the memory card door is progress: this is now much more stable, now nothing more squeaks when attacking.
When you first turn immediately notice the redesign of the menu, number of pages, colorful, not really complicated for a canonista .....
Under autofocus's is really interesting. Because since most did.
61 fields, of which round 40 cross-type sensors. A tremendous advancement over the Mk2.
If you look through the viewfinder, you see when you press the AF selection button the fields, which not least also extend through the greater number a little further in the edges or corners.
(So largely end with the focus and recompose ", which was not so accurate in high-intensity optics at maximum aperture, apart from the elapsed time until tripping .....)
First experiences with the new Autofocus: no matter which field is selected, the number of sharp photos is impressive. And only the sharpness ....
My 70-200 / 2.8 IS II is good, that I knew the 24-70 / 2.8 seems to have improved.
Whether this is the improved AF or lens and camera harmonize better, I can not say ....
The speed of the focusing process is roughly comparable to the 1D Mk4, so fast, very fast.
All this in one-shot mode.
The tracking mode (AI), ie the calculation of a moving object with respect to the triggering is also considerably better, entrained in a show jumping competition and comparison 1er no difference, subjective.
And what can be selected: all fields, individual, small group; all these with appropriate SUB MEMORY movement shifted with the one with the knobby, like the 1D Mk4.
(Criticism: in AI Servo the field is unfortunately black, you siehts sometimes badly or not; Canon considered an update, since there would otherwise trouble with the metering, if it were continuously active, so wait.)
The 6 frames / s are also welcome for me, the 4 / s of the Mk2 were me sometimes too sedate.
So we are approaching a further improvement and related party pooper.
The camera has a CF and an SD slot. If you photographed what important, yet easy paranoid stores on both cards, you realize that the Mk3 supports UHS-1 protocol for SD card NOT.
So if the camera RAW + JPEG takes (any resolution), you can see right down 7 ". Then the buffer is full. Too bad.
When set, only "RAW it would be approx. 13
So to say, the camera is faster, but also the Buffer full faster ....
And wait for a series: I am reminded of the days of the 300D.
edit 08.07.2012: to the camera to move faster image sequences: Do not save to an SD card, not alone, not in parallel.
The emptying of the buffer is then determined by the slower card.
And only adjust RAW, which can make the computer jpegs.
Cards recommendation: everything with 60MB / s (400x is elsewhere) upwards, is currently spearheading the Lexar 1000x.
For sensor: whether now progress with jpegs been conceded directly from the camera in the form of less noise at high ISO, I do not care.
RAW: yes, they are a little better. 6400 was formerly my personal limit in terms of quality, so it is now 12800th
At low ISO, I notice no real difference. If the images are actually a bit sharper? By few pixels more? Rather the better AF system.
In conclusion: the Mk2 is not inferior by its successor. Anyone who takes time (landscape, HDR etc) is very well served with her.
Who needs a bit brisk at slightly improved noise values at higher ISO range (wedding, portraits, bissl Action goes well) the was ours recommended.
Whether it justifies the extra price must each decide for themselves.
(For me personally and as a passionate photographer of people and scenes, so snapshots: it is beneficial to use the now much better autofocus 2 people, so chose a field outside, and the thing sits No more loss of time, you stay the whole.. time focused. When MkII there were too few fields and the outer were not always reliable.)
From my perspective: clear recommendation for a special camera and all-round quality!
