I'm sure this is a stupid question but i dont understand,Its about f stops on lenses.I have an 18-55mm f/3.5-5.6 lens, I understand that at 18mm it is f/3.5 and at 55mm it is f/5.6. But my question is I can adjust my command dial on the camera to f/22. the largest aperture is f/3.5, but is the smallest f/5.6, or can I go to f/22? I hope this is understandable,I had a hard time trying to explain what I'm asking. anyway,thanks in advance for any help.
