Originally posted by Christine Tham Friend of mine just upgraded to the D810 from the D800e. He says it's NOT "2-3 stops" better but there seems to be an improvement. It's also NOT noiseless above ISO 3200 - no camera is.
The main reason for the upgrade was to get rid of the focusing problem on the D800e - sometimes the shutter won't fire after focus lock, because it keeps hesitating whether lock has been achieved or not - tends to happen when trying to focus on relatively smooth surfaces.
The D800e was a bit of a kludge (AA and anti-AA filter stack) - the D810 fixes most of the issues.
The only time my D800E seems to "hesitate" before firing off the shutter is if I have set the AF to focus priority and it's not sure that it's focused. You friend's camera is doing what it's supposed to do if it's set up like that.
I have a D810 and it is a wonderful camera - although I've just been told my the serial number means it's affected by the dreaded "White Spots" problem. It'll be going to get an adjustment next week that will, hopefully, cure it..
