The RX10 III is more than enough camera for most families and backyard wildlife the RX10 IV adds much faster autofocus and burst capture, giving serious photogs a reason to spend more. It's upgraded the RX10 over the years, and currently sells two editions, the RX10 III and RX10 IV, each with an excellent 24-600mm f/2.4-4 zoom lens and pro-grade build. It didn't take long for it to follow with the RX10. Sony started putting 1-inch sensors into cameras in 2012 with the pocketable RX100. Going in the other direction, the Panasonic FZ300's lens is a mere 24x power (25-600mm), but it maintains an f/2.8 aperture throughout the entire range, and features one of the best EVFs in its class, along with a weather-sealed design and 4K video capture.

It's huge, heavy, and priced on the high side, so it's definitely not a camera for everyone. Nikon also has the P1000, with a one-of-a-kind 24-3,000mm (125x) lens, Raw image capture, and 4K video recording. You can go longer when it comes to zoom-the Nikon P950's 83x zoom lens covers a 24-2,000mm range-but image quality at the extreme telephoto isn't as good as it is at wider angles, and autofocus definitely struggles with tiny, quick subjects. It also sets itself apart from many pocket models and smartphones by offering Raw capture, a very solid optical stabilization system, and an electronic viewfinder.
Our favorite model, the Canon SX70 HS, sports a 65x lens that covers an ultra-wide (21mm) to an extremely narrow telephoto (1,365mm) angle. You're not going to see a significant jump in image quality when compared with a pocket model, but you'll be able to enjoy zoom ratios in excess of 50x power. Some bridge cameras pack the same size sensor that you'll find in a pocket point-and-shoot or a premium smartphone like the Samsung Galaxy S21.
