Hi, I have a question about a battery that I got on Amazon for my Canon. I simply searched under the exact battery needed and went for the best deal. It turns out that the source of the battery was China, and when I tried to use it, a message popped up on my screen asking if this was a Canon sourced product. I tapped “no,” and then it said that I was not guaranteed that it is safe. So my question is, should I send it back for a refund and purchase a more expensive Canon sourced battery, or should I not worry about it because it is just Canon corporation wanting me to buy from them?

A few months ago, I bought a used AF-S Nikkor 24-120mm 1:4 G lens. My intention was to have it as a "sometimes" alternative to my 17-55mm f2.8 DX Nikkor zoom for my D500. (I also have come to enjoy using it on my D850.)

The issue is that the HB-53 hood that is designed and intended for that lens really provides only minimal protection against flare, since it has to be shallow enough to accommodate a 24mm field of view without vignetting. Of course, when I use that lens on a DX body, the hood only has be shallow enough to accommodate the field of view of a 35mm lens, meaning that a deeper hood could work just fine.

So...now the question is whether any of the members here know of a deeper Nikkor bayonet lens hood that will mount properly on that lens while providing protection down to a 35mm full frame field of view.

Thanks in advance.

The last 2 years, I have been on the photo press corp for the Reno Air Races the last 2 years. I bring multiple cameras and lens. but both times using the 200-500 Nikkor lens on my D810, using burst shooting a lot, freezes up my camera, generating an ERR issue, to the point where I cannot turn it off, or do anything. I have to remove the secondary battery pack, and remove the primary battery, , then reinstall all. Works fine for about 3-4 burst shots, then freezes up again. the 2 memory cards are Sandisk Extreme Pro with a speed rating of 170mb. I rented the lens both times and have no idea if it was the same lens or not. Sent my D810 in for servicing to Nikon service Center, and they could not find anything wrong with the camera. Their technician said this should never happen. This does not happen with I use my 85-200mm Nikkor lens with a Teleconverter. Has anyone else experiencing this issue? I usually shoot from inside the racing pylons, where you see aircraft coming at you between 300-500mph at traveling sometime over 875 feet per second.

After becoming very comfortable with my D500, I recently decided to dip my toe into the FF world by picking up a pre-owned D810. For birding, i have the Nikon 200-500, the Nikon 300 PF (and 1.4 TC), and the Tamron 100-400, all of which I love. I’m wondering if and how to use two cameras for birding? If we are in a single location (not hiking), my instinct would be to mount the heavier combo (D810 and the 200-500) on my tripod and use the D500/300 PF for handholding for BIF opportunities. Or, is trying to use both more trouble than it’s worth? Any thoughts or suggestions would be appreciated.
