My shiny new 5d MK II arrived today, but i have an initial disapointment, i will be using this camera in a lot of low light situations so decided to do a quick comparison with a friends 50d in my room lights down low looking into the cupboard which was fairly dark, the 50d Autofocus locked on in a split second, when i used the same lens ( 24-70) with the new MKII it just kept hunting and would could not get a focus lock, it seems fine in normal light conditions.
Has anyone else found this? Is it normal? Maybe im missing something ?
Any advice would be brilliant
