This will be a variable aperture zoom. More transparency for you depends on the focal length you use.
At 18mm, the largest opening of F3.5 and 55mm, the maximum aperture F5.6. If you move between 18 and 55 mm aperture of the development of the road.
This design, rather lower in the objectives of consumer policy, joint quality and thus costs, but at the expense of speed. Canon has a 17-55mm F2.8, which can accommodate a maximum aperture of f2.8 at all focal lengths. But this lens costs more than $ 1,000.
If you have all the way up to 55 mm, you can not use f/3.5. You have up to 24 mm (not exactly cut out) get to f / 3.5, sure you can get it in 18 mm. In contrast, can not be used in 18 mm, f/32.
It is the design does not do light.
To take advantage of the opening of f/3.5, you need to keep the focal length of 18mm.
the 18-55 mm f / 3,5-5,6 has a maximum aperture of f / 3.5 to 18 mm and 5.6 to 55 mm
You may experience f/3.5 18 mm
A 55 mm and the maximum aperture f/5.6
