With an optical zoom of 42 times zoom factor, the Lumix DMC-LZ40 has one of the biggest optical zooms amongst cameras of this age. The optical zooms of cameras of this type and age range from 0.34x to 65x, and the average optical zoom is 16x.
We compared all the other 42x optical zoom cameras to this camera and we think because of it's better review score, the Nikon P520 is also worth considering.
If this Panasonic digital camera optical zoom is too small for you then you might also want to look at the Sony DSC-HX400V (£282.99) (50x) which also has a higher rating.
