I shot four polo matches today using a Canon 5D. The files are extremely ROBUST. By this I mean that they are highly amenable to extreme Lightroom adjustments without beginning to look like crap. Impressive as hell.
6 fps is barely adequate. The swing of an arm happens in a fraction of a second and the length of time between clicks means an entirely different picture. I think to do it right you need minimum 8. Ten is borderline overkill, and you start getting quite a few of exactly the same shot. I think beyond 10 is a recipe for filling your hard drive needlessly.
The autofocus is "jumpy" and a bit frenetic. I just don't know how better to put this. Over the course of the day I tried ever different autofocus preset and it remained jumpy. It would latch onto subjects, then unlatch.
Reach. Obviously I miss the crop factors of the 1D4 and 7D a LOT on a huge polo field.
This is exactly the type of real world feedback I've been waiting to read. Thanks Smirkypants. +1
6 FPS feels slow? Yes, it's amazing how much action happens between frames shooting at 10 FPS on the 1D4. Anyone serious about shooting action needs to sit tight for the 1DX or stock up on 1D4 bodies with the very useful x1.3 APS-H sensor. I've said it before & I'll say it again...I like
Reach? Yep this is another issue with expensive solutions as we move from APS-C & APS-H to FF whether that be 1DX or 5DIII. Who else is looking at less useful 300 f/2.8 lenses and realizing they are going have to drop the Mastercard on a 400 f/2.8 sometime this year. Sigh...
AF? We were told the 5DIII would AF better than the 1D4. Maybe it will improve when the grip ships with the twin battery option. Could be the complex configuration of the AF didn't suit your subject.
