I'm currently shooting with a 60D and 5D Mark iii. I was originally going to get the 1dx but the 5d iii came out sooner. I wanted something with high fps, and am wondering is it worth spending the money. I know it's an amazing camera, however a 1d mark 4 is a lot cheaper lol
If you have a 5D Mark III and are satisfied with the IQ, AND all you want to add are higher fps, then no in your case I'd say it's not worth it. Are you going to be a paid sports photographer? If not, get the 1D Mark IV. If you are, then I'd go with the 1DX over the 1D4 personally. It's a lot of money either way. I guess you could sell your 5D3 and buy a 1DX too.
If I mainly shoot sports,would it be worth it to upgrade from the Canon 1D MKIV to the 1DX?Would I miss the reach factor a lot of 1D MKIV if I switched to the 1DX?And lastly,how much better is the IQ of the 1DX than the 1D MKIV?
