Having the last of some Beacon in the MM Monogram whilst hunting bald eagles with the Nikon D3x and the 200 f/2 Nikon lens mounted on the Manfrotto 52 Pro tripod.
Got a few last week but the camera was acting up so I ran the battery through a calibration cycle to see if that took care of the problem which the lens kept seeking and not locking on. It locked on to the nest just fine but I only got a few peaks of the head of the one on the nest, the other was out hunting up something to eat, guess they have an egg, will post photos when I have them.
