![]() Got this lens but seldom use. But I notice whenever I try to take a distant picture of an object, some of the edges will look neon in a way. How to solve this issue? Is a UV filter a solution?
![]() Subject was taken outside my window this afternoon. Can spot the discolouration on the branches? ![]() ![]() ![]() Last edited by Koji™; 31-07-2010 at 12:29 AM. |

bro koji,
the "neon color" thing you mentioned is known as chromatic aberration CA or commonly known as purple fringing as it is usually purplish in color, sometimes it gets bad enough and it will be thicker and look greenish too. it usually occurs at borders between high contrast edges like the bright sky and the dark branch and also at the tail tip of the bird against the bright sky. this is inherent of the lens and a uv filter does not help. most zoom lens will have this problem especially at the tele end. some higher end lenses minimize this CA by using special glasses and coating and hence the much higher price. |
