Help Needed With Nikon Gear AF Mystery …<\/strong><\/h2>\n

The Situation<\/h3>\n

Tripod-mounted Nikon AF-S NIKKOR 600mm f\/4G ED VR AF lens<\/a> with or without the Nikon AF-S Teleconverter TC-14E III<\/a> with the Nikon D850.<\/a> AF-C with shutter button AF. <\/p>\n

Please note that the problem only occurs when I am working with the camera oriented vertically. <\/p>\n

The Problem<\/h3>\n

When I select an AF point in any AF area mode, the AF point moves on its own when I half-press the shutter button. Sometimes it moves up and down, sometimes side to side. The system never locks on. I’ve tried this with and without the TC-14E. I have tried it with d-25 and with Group and with S (single) and with d-9. I have previously had the same problem with the TC-E20. I have checked every Menu item I can think of and not only do I have no clue, I have never heard of anything like in with any camera system. My understanding is that once I pick an AF point it should stay exactly where I put it … <\/p>\n

This problem has occurred sporadically before this morning when it did it consistently. <\/p>\n

If you have a clue, please leave a comment. <\/p>\n

thanks with love, artie<\/p>\n

This Just In …<\/h3>\n

I had a thought that perhaps the issue might have to do with the vertical grip. I tried it again in the hotel room and the problem showed up only sporadically. Then I thought to use the shutter button on the camera body rather than the shutter button on the vertical grip. Again the problem occurred sporadically only when working vertically … So it seems likely that the problem is not with the grip. I cannot try without the vertical grip because I do not travel with the smaller batteries. <\/p>\n","protected":false},"excerpt":{"rendered":"
