thanks for all the replies guys. I really appreciate it.
live view is not important to me currently, I'm not sure if I'll ever consider it an important decision factor. But thanks for mentioning that.
The AF accuracy issue however is troubling. :/ I have no doubt that k-5 will be able to deliver top notch image quality in low light, as long as the shot is taken correctly. However shots missed when they shouldn't bug me. I have done some research after anvh's post. It seems to be a prevalent issue. There also seems to be a consistent front focus in tungsten light. I have also stumbled upon some information that af can be fine tuned in-camera? If there is a walk around that essentially creates a tungsten light af mode, I could live with that.
I mostly shoot people and about a third of the time it's in tungsten lit settings. This is possibly a deal breaker if it's a real problem with no walkarounds
