Re: confused by the numbers & letters for lenses

Hi. The f/No's are a bit confusing to a beginner, & I only started 12 months ago so am still very much a beginner. The confusion arrises because the smaller the f/No, say f/3.5, the LARGER the aperture, & the larger the f/No, say f/5.6 the SMALLER the aperture. It does take a bit of getting used to, but you will. If I can grasp it, anyone can!!. The other poster has explained the rest very well. No doubt you will recieve more info to help you.
