I really don't know much about lens... I am planning to get one for the G2. Is there any good website that described about lens and how to read its specs? like those numbers F3.4 or so on, what does it means?
I think the 1st lens I want to get is one that fits in the G2 so that it will protect the lens and save myself the trouble of putting on and off the plastic lens cover. What brand would u recommend for such usage?
