Nie porównuje go do innych marek, ale do 1DXI i 1DXII, które posiada:
Here are my feelings after two days of shooting with the Canon EOS 1DX MKIII. I can only compare my experience being a first adapter of the 1DX and 1DXMKII, shooting professionally for Sports and Runway Fashion.
I find there to be no "noticeable" upgrade in IQ and in some instances, greater noise
There is a "muddy" lack of definition across a variety of shooting circumstances
fur and Human hair exhibit an unusual lack of definition and noise
At reasonable ISO levels, there is too much noise
Color rendition utilizing AWB in "Standard" has been way off. Oranges are of particular weakness. "Fine Detail" corrects some of these anomalies
Focus points are particularly difficult to follow and see even when on the brightest settings. Single point is beyond arduous. I like to see where my camera has focused clearly and distinctly in and out of single point.
Switching between M. AV, TV, should be with brighter larger indicators in the OVF
Focusing on objects coming straight at you has improved
Single point expanded still exhibits drift outside of the visual parameters of the grouping
Exposure runs "hot" and based on the noise of the MKIII this is particularly difficult to work with outdoors in bright sun and stadium lighting. Runway for fashion where mode'ls faces, tend to bloom, at front of stage, will provide many issues. ETTR should be avoided unless utilized taking this into consideration.
I'm having issues with the 600 EXRTII that I still can't resolve that I can't replicate on the MKII or 1DX. I've not used strobes yet.
For video, there are many enhancements but I'm a still photographer and can't speak to them nor am I qualified to review video.
The advantage with the MKIII, if greater IQ is not needed, will be when placed downfield, with athletes moving straight at you with a zoom like the f/4 200-400. This is an improvement over the MKII. Most "trained" will get the same number of keepers with the MKII. Another improvement, I could not get the buffer to overflow with the MKIII. All my Wise 512GB cards are still on backorder.
If you're looking for greater IQ by buying the MKIII, not the right choice.
