Black Friday is technically just a 24-hour event, but thanks to online shopping, the deals now often start way before and continue throughout the weekend. For anyone who misses all the deals, the sale period wraps up with Cyber Monday on December 2, bringing even more tech discounts on the remaining camera stock.

Not only is the Nikon D850 my pick of the best DSLRs for astrophotography, I think it's the best DSLR on the market — and there's a huge $800 off this Black Friday.

If you're looking for a new camera, we've got an excellent Black Friday deal to share with you. The Nikon D850 is the best DSLR on the market, and B&H Photo currently has $800 off its MSRP. That means you can take this powerhouse of a camera home for just $2,196.95 instead of $2,996.95 — and it's the same price on Amazon, too.

We found the sales on some of our favorite gear, including Gold Award-winning cameras, excellent lenses, and accessories.

As of Nov. 23, Amazon is offering up to 77% off security cameras and video doorbells. Shop Blink, Simplisafe, and other top brands for less.
