Suprisingly, the Zenitar 16mm/f2.8 is one of the cheapest lenses available and is also very good. You just need to be aware that individual samples can vary in quality, so you need to buy one that you can try first or go to a decent dealer. On 35mm, it's a fisheye but this is reduced noticably when used on a DSLR. It's a manual focus, non-A lens, so you need to set the custom function allowing use of the aperture ring, use M mode and press the +/- button before each shot. > > I know the aperature controls how much light enters the lens (along with > shutter speed), and a smaller aperature number means more light can > enter.
