Hi Guys,

If the dust can be visible on 17mm but not 35mm.. so it's on the lens right? ;)

It also depends on how far you have stopped down your lens. At f/5.6 and below, dust bunnies are usually invisible but at smaller f-stops (larger numbers) the gradually become more visible.

Try shooting at the sky with f/16 or more for both lenses and compare again.
