The camera lens focal length and aperture is how to adjust
The aperture range of the 1,18 end is 3.5-22, and this range is adjusted for you. 55 side is 5.6-32 this range of casual adjustment. Usually 1/3-level aperture for a file.
2, yes, you understand right, this lens will be the largest aperture with the focal length of the longer and reduced.
18-55 is a floating aperture, adjustable in the 18th aperture to the minimum, that is F3.5-F22; 55 side can only use F5.6-F32.
35mm maximum aperture should be F4.0 or F4.5, I guess ~ never used 18-55
