Canon has launched two new bridge cameras, the Canon PowerShot SX520 HS and Canon PowerShot SX400 IS. 

The two new bridge cameras are focused on offering powerful zooms on a reasonable budget.

Canon’s PowerShot SX520 and PowerShot SX400 offer 42x and 30x optical zooms respectively, packaged within a slightly redesigned body with a new handgrip for ease of use. 

The Canon PowerShot SX520 HS is available in the UK in August, retailing for £299. The PowerShot SX400 IS won’t be available until September and will be an Argos exclusive priced at £259. 

Canon PowerShot SX520 HS Features
The Canon PowerShot SX520 HS features a 42x optical zoom with a 1008mm maximum focal length for making sure you capture the action in the distance. 

It comes with an improved Zoom Framing Assist Auto mode, which apparently automatically detects when a subject is moving out of frame and readjusts the zoom to keep it in focus. 

Both model have low-shutter lag, improved algorithms over the previous models and a revamped AutoFocus system. 

The SX520 HS is fitted with Canon’s acclaimed HS system, combining the DIGIC 4 Plus processing engine and a 16-megapixel back-illuminated CMOS sensor. 

You can record full 1080p HD movies with the SX520 HS too, and utilise the bridge camera’s Creative Shot, which adds five additional shots with each shutter press, each with a different creative effect added. 

Unlike the SX400 IS, the more expensive PowerShot SX520 HS has a full manual mode to play with as well.

Canon PowerShot SX400 IS Features
The cheaper of the two new bridge cameras, the Canon PowerShot SX400 IS has a 30x optical zoom and offers a 720mm focal range. 

It features a 16-megapixel CCD sensor and the same Canon DIGIC 4 Plus image processing sensor as its bigger brother. 

For those looking to add a little personalisation to their shots, the SX400 IS has a range of creative filters, including a fisheye effect. 

You’ll be able to record 720p HD movies with the SX400 too.
