Hi Sifu,

Currently i plan to upgrade my camera, but before that, i plan to sell my old EOS 550D.
However, i notice that 2 of my lens seem infected by fungus.

Here the question. I have these 3 lens,
1. Zoom Lens 55-250 1:4-5.6 IS Affected
2. 18-55mm 1:3.5-5.6 IS Affected
3. EF 50mm 1:1.8 II

Is it still worth to clean it before i sell it or i sell it at lower price as it does not affect the picture.
Need some advice.
