Hi all,
I've got some noob questions on understanding a lens specifications.
Q1: Say for lens like EF 70-200mm f/2.8L IS USM, does it mean the f/2.8 is the highest aperture value the lens can go?
Q2: For EF 70-300mm f/4-5.6 IS USM, what does "f/4-5.6" mean? That the max f value is variable?
Many thanks
