Yup.. I wanted to stop the hear say thing coz a friend of mine thinking of getting soon. I read kenrockwell reviews and he din mention such problem also. So to convince my friend, I like to reference clubsnap coz I think this is the biggest and truthful photography forum around.
For myself if I were to upgrade, d800 is one of my choices. You are right, I'm not in urgency to upgrade yet.
What makes you think that? I'm willing to bet a large % of the Nikon users here also read.believe Ken Rockwell.
FYI, if you did a search and don't see any issues, wouldn't basic, primary school logic then imply that nobody reported/knows/heard of such issues, so you should ask your "friend" what the issue is? If all he can say is "firmware lah! firmware lah!" then it's obvious he has no idea what he is talking about.
