[QUOTE="Sam003, post: 84358, member: 11285"] Hi All, Can someone please clarify me with the below question. I'm trying to understand fixed aperture with variable focal length lenses. Imagine I have a f2.8 70 - 200mm lense my understanding is aperture will remain at f2.8 when you change your focal length from 70 to 200mm but you can control the aperture size with your camera body by using it in aperture priority mode, so setting it to f8 in your camera the amount of light passing will be less in this case even if your lense aperture is f2.8. Please correct me if my understanding is wrong. Thanks. Sam. [/QUOTE]
