That, and the storage required is pretty crazy. Then again, I suppose a 1D series camera isn't exactly the wedding photographer go to (though, I do know a couple who use a 1DXII and another with the similar D4).
Jeah, I think the 1DX II got for wedding PHOTOGRAPHERS a lot of pros and cons:
- very loud
- very heavy
- not that much resolution
+ nice viewfinder, good AF, good Lowlight
The cons overweight though in my opinion and I prefer my 5D IV or sony a7R IV
For Wedding VIDEOGRAPHERS its a whole other story in my opinion:
+ pretty much the only camera with nearly full-frame 4k 60fps which is realy great
+ incredible nicecolors out of camera, beautifull skintones even without any grading
+ very useful AF, especialy for working with a gimbal...
- ... which you need because you have no ibis
- quite heavy and quite big files
The Pros overweight in my opinion which makes it a great choice for wedding videographers.
The 1DX III will certainly be a beast in that area of work
(If people are willing to work with the weight and filesizes)
