The Canon PowerShot SX730 is all about zoom, portability, and connectivity. Boasting a nice 40x zoom lens, the camera is still a compact 10.6 ounces.
The SX730 uses a 1/2.3" sensor, a pretty standard size for a compact camera, with 20.3 megapixels. The 40x zoom, however, is a bit above average, since most compacts this size top out at 30x times. An optical stabilization system will help keep shots steady when taking advantage of that long zoom lens.
Feature-wise, the SX730 is pretty basic for a consumer camera. There are no manual modes or RAW shooting, although there is a skin smoothing effect available in every mode and several auto settings. The speed is a middle-of-the-road 5.9 fps, which drops to 4.6 when using continuous autofocus. Video is in HD at around 60 fps.
The Canon PowerShot SX730 appears to be a decent though average camera -- but the price seems a bit steep for the included features at $399. For that same price (or less), both the Nikon Coolpix A900 and the Panasonic Lumix ZS60 offers manual modes and 4K video. The Sony WX500 is also similarly priced with a faster burst speed. If you really need that 40x optical zoom over the 30x, the Canon SX730 is a decent option, but you're paying a premium while still missing out on 4K and manual shooting.
