So, I\'m uploading a video to Vimeo right now. Not sure how long it will take to upload, but thought I\'d start a quick thread.
My D800 is acting weird. When tracking Birds in Flight, as soon as one of the AF points misses a target, the lens starts shuttering back and forth working it\'s way towards min focus. At that point, while still holding the AF button, it just sits there and does nothing. It takes multiple AF presses to get the lens to start heading back towards infinity to see if it will pick up focus.
Very frustrating and my D600 does not exhibit this behavior at all. It works as it should.
Things I have tried with no success:
1. Changing number of AF points from single, 9, 21, 29, 51. All have the same issue.
2. Change the tracking from slow to fast to off. Usually set to off. No effect.
3. Reset all camera settings
4. Changed firmware to original, then back to latest.
5. Uncoupling all lenses/teleconverters
6. Removing battery
7. A/M - M/A switch - no change
7. Trying a new charged battery - no change
8. Trying a different lens. (longer lenses are worse)
9. Shorter lenses seem to work better.
Another way of looking at it. On my D800 now, as I move from an area where enough contrast exists to achieve focus to one where there is little to no contrast, like going from trees/land to the sky, the camera looses focus and chatters
back to min focus and stays... only with multiple AF-on presses does the focus attempt to come back
Contrary to my D600 where perform the same movement is made from trees/land to sky, the focus usually stays and locks onto the clouds, but if it does loose focus, it makes a quick sweep to min focus, then back to infinity where it usually grabs focus again. As long as I\'m holding the AF button on the D600, the af is either searching quickly for a target or locked on and maintaining focus. My D800 used to be like that....
So any hints. Where do I aim a blower to get the af module clean if there is dust on it?
Thanks in advance.
