Many people say the 1Dx2 is overkill for wedding work
I disagree big time
These smaller 20MB files on the 1Dx2 or much much better and easier to work with in post processing. and the color is a ton better as well
additionally, the AF performance on the 1Dx2 as compared to the 5D4 is nite and day. 5D4 still misses more than I would like with a moving object. especially in back light situations. In a reception room where I must use flash. 5D4 will still hit a bright light behind the subject where as the 1Dx2 is far far less frequent.
lastly- the 1Dx2 captures images like this routinely. Not as routine on the 5D4. If you demand the best AF performance then I encourage to step up to the 1Dx2 over a 5D4 if you shoot weddings professionally
This was my groom and his guys having some fun while the girls were spending 3 hrs putting on make up and getting hair done. we decided to have a bloody mary for breakfast and go shoot some clay ducks. 1Dx2 was perfect for these needs
