As with the shutter speed, the aperture also affects the sharpness of your picture, but in a different way. Changing the aperture changes the depth of field, the depth in a scene from foreground to background that will be sharp in a photograph.
Coma may sometimes appear, also, when an otherwise satisfactory lens of normal focal length is used for close-up photography or photomicrography. The effects of coma can generally be reduced by closing the lens aperture. In close-up work, reversing the lens, back to front, on the extension tubes or bellows will usually much improve the image, and the coma effect may disappear completely. More about Camera Lens.
