Originally posted by ozturert You cannot take wedding photos where you need to catch moments with a manual lens so you need a solid 24-70mm f2.8. Still, low light focus capability of K1 is nowhere near even d700 (maybe slightly better than D610).
You don't need only high ISO capability, you also need to nail the focus when you need it.
I must have missed that brief. I took this (amongst many other perfectly focussed shots) last night at a 21st party. This is very heavy crop with the K-1 and DFA*70-200 @ 200mm wide open. This girl doesn't stand still and it was quite a task following her around.
Yes, it's a flash exposure, but the ambient light (during which the AF happens) was pretty damn low, as you can tell from the size of her pupils.
The K-1 might not have industry-leading tracking AF, but in low light it's very good indeed. If you can't nail focus with it you're doing something wrong, or you have the wrong lenses.
