The smallest optical zoom of medium megapixel cameras that have been available for more than two years is 0.34x, the biggest is 65x, and the average optical zoom is 14x. At only 5 times zoom factor, the Sony DSC-W620 has a fairly small optical zoom compared to most of the other medium megapixel cameras that have been around for around the same time as this digital camera.
We compared this digital camera to all the other 5x optical zoom cameras and we think because of their better review scores, the A3350 IS, and the A2400 IS both from Canon or the Sony DSC-W580 are also worth considering.
If you are looking for a bigger optical zoom then you might want to look at the D5100 + AF-S DX NIKKOR 18-105mm f/3.5-5.6G ED VR (£239.99) (5.8x and higher rated), the Coolpix S5200 (6x and higher rated), or the 3200 (6x and higher rated) all from Nikon.
