ok, so i have Nikon D7000 and i know the basic relation of shutter speed aperture and iso. All i want to know is focal length and aperture relation.
as i zoom in the camera the f stop increases eg from 3.5 it becomes 5.6 some one told me that having large aperture gives more blurry background. (ie: f3.5 will give me more blur than f5.6, if i am not wrong)
but when i zoom my lens to 140mm minimum f value available becomes 5.6 and it gives me more blurry background than f3.5 at 18mm
why so? Am i wrong at some concept please make it clear:) thanks in advance
