[QUOTE="Pierro, post: 45413, member: 8517"] I've noticed a weird problem here - with the 80-200 dual f2.8 on a D2x and using AF & MF. Both modes see the green dot Focus Confirm light up at completely the wrong point. The focus is so obviously way out, yet the green dot lights up. This wasn't just a tad out, but way out. Can be seen in the VF even before the shot was taken. And the contrast on each photo looks completely different - no other settings were changed. They were taken only seconds apart, just long enough for me to switch from AF to MF Converted from NEF to JPG, no processing, and 100% centre crop on both. Sign is quite big, maybe 16" top to bottom and distance was around 40ft [B] AF with 5 shot burst, middle shot[/B] [B]shown[/B] [IMG]http://photo-sharing.winsoftmagic.com/1/soqidn3ysh.jpg[/IMG] And switching to MF on lens, leaving in AF-S mode, green dot lights again at completely the wrong point, so ignoring the GD light, I manually focus and green dot disappears altogether, not even flicking in and out like it was just on the border of correct focus. I get correct focus according to my eye and take 3 burst shot. [B]MF with 3 burst shot, middle shot shown[/B] [IMG]http://photo-sharing.winsoftmagic.com/1/rb74uydc6v.jpg[/IMG] I'm not clever enough to know whether this is a lens or camera problem ..something is amiss.
