Hi all,
I've been toying around my dslr kit lens for quite some time and i decided to buy a new lens. But i've no ideal what to look out for in a lens and what does the details in the lens means.
So I'll list out what i know about a lens and correct me if i'm wrong.
Canon Zoom Lens EF-S 18- 55mm 1:3.5-5.6 IS
Canon: This is the brand of the lens
Zoom Lens: Zoomable lens
EF-S: Mounting system from what i've read but don't know the differences between EF and EF-S.
18-55mm: How far it can zoom... is this the focal length of the lens?
IS: means there's image stabilizer.
Then there's weird sign beside it wrote 58mm... not sure what that means... maybe some can enlighten me
1:3.5- 5.6: The aperture of the lens... denotes the speed. Does this means that at 18mm, the f.stop will be 3.5 and at 55mm it'll be 5.6?
Thanks for all the inputs.
