Sometimes, we may have heard of notions like normal lens and standard lens. What is the actual meaning of these notions? Normal lens is actually a lens that has a focal length (focus distance) all along the diagonal size of image sensor camera. For a camera with full frame sensor (36 x 24mm), the normal sensor is 43mm. on the other hand, on a camera with APS-C sensor size (23x35mm), the normal lens is around 28mm. and for four thirds sensor, the normal lens is about 21.5mm.

Lenses ideally project the color spectrum right on the sensor, creating a sharp image. But in reality, there are several colors in the spectrum that aren’t precisely projected, especially in low quality lenses. In cases like these, the focus falls outside the intended focus point, sometimes in front and sometimes behind the sensor. This means that it spreads or disperses (not focused on one point). Because it doesn’t fall on one exact point, chromatic aberration is resulted in the photographs produced. Characteristics of a chromatic aberration is the visibility of odd colors on the edges of the objects in the photo, usually in the color of purple, blue, green, or red.
High quality lenses (like Canon’s L Series or Nikon’s ED Lenses) uses optic materials that have super low dispersion, minimizing the spreading of colors.
A few tricks to lessen Chromatic Aberration are: Read the rest of this entry »
