Next week, I am shooting a VB tourney for 2 days, and I am renting a 1D Mark IV as a trial...trying to decide 1D MIV vs 1DX.....
You wont want to hand back the 1D4 ...
Wow you are not kidding - just started last PM for practice. The ISO range difference is unbelievable c/w 7D. Indoor, no flash, no problem.
Took a walk in my neighborhood last night before a snowfall (so no contrast on the ground), with only moonlight, and got interesting / usable handheld shots at 1/15 and 1/30.
Shot indoor volleyball then indoor soccer (my kids are very busy), and paired the 135 with both the 7D and the ID IV - didn't have time to process yet but first glance I liked what the viewfinder shows, but my wife is not gonna be happy (neither is LENSRENTAL) - I may not return it
I will shoot similar shots this weekend with the 135 using both bodies for a real-life comparison and post next week.
