Thought this might be of use to someone.
Lens Specifications and Measurements
It lists a whole host of specs and measurements for the given lens (you can compare two lenses at a time).
What was most useful to me was the aperture info - what the aperture is for any given focal length.
Most reviews, tech specs etc, only provide you with the extremes of the lens (e.g. 18-55mm f/3.5-5.6), but you don't know at what focal length the aperture changes.
So using the 18-55mm as an example, I can look at the aperture info and see that e.g. at 28mm the aperture is f/4 and at 40mm onwards the aperture is f/5.6.
Certainly very useful when looking at potential new lenses to see what aperture a focal length will give.
