Also helpful for astrophotography was the lens' fast maximum aperture, which let me shoot the stars using shorter exposure times than I would need with a slower lens. In optics (especially telescopes), the coma (/ ˈ k oʊ m ə /), or comatic aberration, in an optical system refers to aberration inherent to certain optical designs or due to imperfection in the lens or other components that results in off-axis point sources such as stars appearing distorted, appearing to have a tail like a comet.Specifically, coma is defined as a variation in magnification . A lens taking wonderful images in daylight can give average or subpar results when used for astrophotography.

A single exposure taken through the Kenko Softon A filter layered in with Lighten mode adds the star glows, though exaggerates the lens distortion on the bright stars. The lens is well built and includes weather sealing. But this is more than just an astrophotography lens - its versatility means the lens is also perfect for landscape and architecture photography.

Pretty much all wide-angle lenses are affected by coma, and some of them quite heavily. Each method produces a range of aberrations, although some are common to both types. The maximum aperture of f/2.8 is fast enough to capture insane amounts of light in the stars. The difference between them is the shape of the lens. A wider aperture allows more light to reach the imaging sensor, permitting a shorter exposure or lower ISO setting. 24mm 1.4 for Astrophotography.
