At a function last night in a very dimly lit venue I struggled yet again with low-light AF. The 5D3 with 580EXII & 24-105 f/4is was OK except for the black AF points, which made it unprofessionally slow to always be sure of correct AF, but the 1D4 with 580EXII & 70-200 f/2.8isII was absolutely hopeless with a very large number of missed shots. Both bodies were on one-shot AF mode, keeping as often as practical on the cross-type AF points.the 5dmk3 will actually achieve focus in many situations where a 5dmk2 simply will get nothing
I'm actually considering picking up a couple of pre-owned 5D2 bodies just for these type of events. They have the handy red AF points and from memory are better than than the 5D3 for very low-light AF.
Any thoughts on this? What's the red-hot very low-light hero DSLR hardware?
did you have the 8 expanded points around you selected AF point? this makes a massive difference to low light focus, also the 16-35 L II has amazingly quick AF in very low light i dont think the 24-105 is particularly blazing in this regard, i find the 24-70 mk1 also very fast , 70-200 II no problem either with expanded AF points
granted the black points are annoying as hell though
