I mostly use 24-70 F2.8 on D800 as I need to flexibility of a zoom (as a wedding photographer). I try to avoid using D700 as image quality is so much better on D800. The problem is I need to keep shutter speed up to 1/160 sec to ensure consistently sharp images on D800. I can easily shoot D700 at 1/80 sec and get sharp images. I'm wondering if D600 can be used at lower shutter speeds than D800?
Has anyone used hand held? Does D600 test your technique as much as D800 does?
