5D Mark III vs. 1D Mark IV

Yes, having the built in grip would be very useful. Sometimes I'll be wearing a suit when I'm taking photographs, and it's bad to extend my arms over the top of the camera when shooting portrait without a grip. Suit jackets aren't designed to stretch like that.

The beauty of the 1d4 grip is that changing AF point is easily to hand.

After re-reading some articles, it seems that the dodgy flash performance is related to using the AF-assist beam from external flashes. It's very slow to get focus in this mode, compared with the 5D series cameras (of all generations).

I've read that the weakness of the 1D MK IV, if there is one, is low light AF in general. I did not think its associated with the use of AF Assist.

Am I wrong on this?

I'm looking at getting one if I can negotiate the price down. I've downloaded raw images at high ISO and decided that its close enough to my old 5D MK II at ISO 6400 that its not a issue. My 7D would then be sold.

I would say that the 5DII was better at low light AF than the 1D4

I can give you RAW images if you want at iso up to 12800
