Q: 1. Can Osmo Pocket 3 be closed with the filter attached?

A: Yes. The Osmo Pocket 3 can close normally with filter attached but it cannot be placed in the protective case with the filter still attach.

Q: 2. Can this be used in as a drop in rear element for a 400mm Nikon lens?

A: Unfortunately no. The K&F Concept 52mm Nano-X HD Variable ND2-32 Fader Waterproof & Scratch-Resistant Filter has a 52mm mounting thread for mounting on the front of a lens but the front of the filter has 55mm threads for using a 55mm cap or other filters. Therefore it is too large to fit into a 52mm drop in holder.

Q: 3. Will it fit Sigma 16mm F1.4 DC DN EF-M?

A: Yes, as the Sigma 16mm f/1.4 DC DN Contemporary Lens has 67mm filter threads on the front of the lens, the K&F Concept Nano-X Variable Fader NDX HD Green-Coated Waterproof Anti-Scratch Japan Optics Filter (67mm, ND2-32) is compatible for use with the Sigma 16mm f/1.4 DC DN Contemporary Lens.

Q: 6. I bought this filter for my new Sony AX-53 after viewing the footage, I see a distinct pink cast. Thinking I may have an incorrect setting, I set the filter/protector option to ON.I shot more footage and there was not difference with the filter/protector setting on or off. I still have the pink tint. My video footage was taken in bright sunlight. It appears that I can remove the tint in post but I'd rather not have to do that. Am I missing something? Thank you.

A: It could be a setting in the camera itself. The AX53 has different picture effects you may want to change. It also could be a white balance setting that is causing a pink cast.
