Originally posted by crewl1 I saw the Nikon D600s at my Costco.
I brought in a sd card with me to test it out.
The AF was very quick but I did not like the overall bulk of the camera.
Last Christmas they had the D600 with a two lens kit(24-85vr and 55-300vr). My friend bought one at that time. I have to say it's not much bigger than the K-5, but it is noticeable(more K20D sized). Most of the bulk seems to come from the Prism area, which is understandable. The D primes are also tiny. I bought one during the recent firesale. I don't mind carrying it around. The weight difference is only 100g. The battery life is unbelievable, so you can save 100g by not bringing a spare battery
. I think I will be bringing my NEX 6 for when I want some range while traveling light. My Sigma 100-300/4 is a beast, but no more so than my K-5 with Tamron 70-200 was.
