Nikon has unveiled its latest full-frame camera, the 24.5-megapixel Zf with retro style and technology borrowed from the company's high-end Z8 and Z9 cameras. With a new sensor and processor, it promises powerful features like 14-fps max shooting speeds, advanced AI autofocus and 4K 60p video. At the same time, it's a highly manual camera with a lot of old-school touches and multiple colorways, all designed to touch that vintage-loving nerve. The body and handling emphasizes manual controls, with no less than five dials on top to control shooting mode, video/photo/B&W, aperture, shutter speed and exposure compensation. It also has a pair of shooting dials front and back and a D-pad style controller, but no joystick.

If you're looking for a camera (or drone) for content creation, travel photography and more, Amazon Prime Day has some great deals, including rare sales on popular models. For example, Sony's latest A7 IV model is on sale for the first time at $2,400, or $2,600 with a 28-70mm kit lens -- saving you $100 on each. DJI, which doesn't often discount its popular drones, is selling the Mini 3 Pro with DJI RC remote for $729. Meanwhile, Canon is selling its R50 creator's kit for $850 for a savings of $150, Panasonic has its full frame Lumix S5 on sale with two lenses (including a prime) for $1,700 (40 percent off) and OM System is selling the OM-D E-M1 Mark III mirrorless camera for just $1,300, for an impressive $500 discount. There are plenty of other deals as well, and if you don't find what you want at Amazon, some of the products come with the same discount elsewhere.

Yesterday's hearing with the CEOs of Google, Facebook and Twitter was as messy as you might have predicted -- and we'll get into that below. But I want to start today with voice assistants. Alexa, Siri, Google Assistant and the rest know a lot. But they barely remember anything, which curtails exactly how much they can truly assist with your life beyond music controls, timers and reminding you exactly what shows you've seen Joel Kinnaman in. A new feature spotted for Google Assistant on Android called Memory could transform it into the assistant we need, however.
