The Hoya Pro ND1000 is a 10-stop neutral density filter. If you like those shots with rivers that look like mist, this is what you use to make them. Ocean breakers that transform into blankets of fog become possible with this filter. If you need to reduce crowds around...

If you’re curious about how fast a lens can focus, a great way to measure it is to use slow-motion video. I previously used my smartphone video to do this job, but now I can use my Nikon D850.

Competitor #1: Sony XQD

I tried to look up the D850 camera shot buffer numbers on the internet. All over the map. Either terrible or stunning, depending on who you ask. Nikon claims it should have a 51 shot buffer with the settings I shoot with.

Sigma TC-1401 Teleconverter on their 70-200 f/2.8 Sport lens

You can see how tiny the Sigma TC-1401 teleconverter is. It’s only compatible with a few Sigma lenses, so be careful to do some research first to see if it will work for you. It won’t work on Nikkor lenses. Si...
