Q: 7. Will this screw onto any tripod screw or mount?

A: Yes, it will, it has 1/4-20 thread. However you need to watch the clearance of the thumb screw on the side as it is wider than the rest of the unit... So if you are looking top-down and whatever you are mounting it to has a larger surface area it probably cannot mount. I have used mine sideways in some cases to get around this when I can. But some places it can't work. Basically, it does not lay flat on a table.

Q: 9. Nikon D750 VS Nikon D850 for night time photography which would be the better camera for taking photos at night. In the city and also out in the country. I really like taking photos at night as well as in the day time. Thank You!

A: I would never choose the D750 over the D850. I've been shooting with the D750 for a couple of years and quite frankly....the high ISO just doesn't cut it for me. Lots of noise.

Q: 10. Can I use my D7000 lenses with this model?
