The Canon SX720 offers a big 40x zoom lens--but in a camera that could fit in your pocket.
The older SX710 (and SX700) offered 30x zoom, but the SX720 increases that while still keeping the camera's slim profile. Besides just being able to zoom in on far-off objects, the SX710 also has a nice .4 inch macro mode, making it a pretty versatile camera, considering the small size.
The SX720 can take photos as fast as 5.9 fps. That's actually slower than the older SX710's 8.5 fps high speed burst mode. But, the SX720 can shoot between 4.6 and 5.9 fps across all modes--the older camera had a much slower 3.1 fps across all other modes.
The SX720 also includes manual modes as well as wi-fi for sharing photos with your mobile device.
It's worth noting though, that while still priced more than $300, the SX720 uses the cheaper CCD sensor style. The tech specs also don't indicate any sort of image stabilization system.
While the SX720 looks like a solid camera for the price, the compact travel zoom category is jammed packed with decent cameras. The Panasonic ZS60 offers 4K video, 10 fps burst speeds, optical image stabilization and RAW shooting, though at a higher price point and with only 30x zoom. The Sony HX90 still includes a viewfinder, as well as stabilization and a 10 fps burst. The Nikon S9900 is slightly cheaper and offers stabilization and a tilting LCD screen.
The bottom line? The Canon SX720 has one of the top zoom ranges in the compact travel zoom category, but there are a handful of options with faster performance and more extra features.
