gabordosa

Just to be clear, gabordosa"s problem is just with the Tamron lens, and the camera never plays up otherwise? Perhaps check for the latest firmware and whether the contacts are clean, but I doubt Nikon service will be very interested in a problem with a third-party lens. Tamron might be able to help.

I sent my Tamron lens to the camera shop where I bought it, and they in turn sent it to Amplis for testing. I provided all of the firmware details of my camera and a detailed explanation of the lockout problem, so that there would be no problem in replicating the problem at the camera shop. I was finally told that Amplis found no problem with the lens, and because of this sent it back to me in BC. Their was no test report accompanying the lens...only that they had cleaned the lens. Upon receiving the lens, I went out to determine if my "cleaned" lens would fail in the field, and in so doing found that the camera locked up after 30 shots, then after another 250 shots and then after another 200 shots...all in the same day. Again in the same day, I tested other lenses (Sigma) that I own on my D810 and they not result in the camera locking up. I have reached out to Nikon Support for assistance on this matter, but so far have not heard anything back And considering that my Tamron lens is 1/2 way through its warranty period, the camera shop where I originally purchased my Tamron lens has not proposed any solutions to the matter.

<p>It just happened to me last Saturday while I was photographing a road bike event here in Houston, TX. I was shooting in AF Continuous mode, RAW images going to CF card and Jpegs to the SD card. Lens was the 70-200mm f 2.8 VR. All of a sudden, the D 810 locked up.</p>

<p>I could not figure out what was causing the problem. Turning the camera on and off did not change anything. The in camera battery was fairly new and working well as far as I knew. I finally took the battery out of the camera, reinserted it, turned on the camera and the problem was solved.</p>

<p>Has anyone experienced this issue? </p>

My D810 has been intermittently locking up when I have had my Tamron 70-200mm G2 lens attached to it. Sometimes I can take up to 30 shots before it locks up and other times I can take upwards of 250 shots.
