I have a newbie question about aperture, hope someone can enlighten.
Given a lens of 18-55mm with aperture 3.5 -5.6. My understanding is that 3.5f at 18mm and 5.6f at 55mm. By adjusting the focal length changes the aperture settings as well.
OK my question - is the aperture range the minimum for that specific focal length? The camera itself allows adjusting of aperture as well, and I'm confused between the aperture in the lens and the camera.
Hope you understand what I'm trying to say...
