I have a lens that has some wear on the surface coating. Looks like the previous user was not very careful when wiping the lens. I'm not sure if such minor damage would negatively affect IQ. Is there anything I should look out for? |

So basically I'm just going to look out for flare that reduces contrast. I tend to use lens hoods anyway, so I guess the lens will be fine. |

Oh it is, actually. However, I'm using 4/3 cameras, so the image circle is basically cropped. Will that be an issue? |

Olympus 4/3 more sensitive for lens quality. I did super shoots with Nikon D50 with many Tamrons, they are much less good performer on 4/3.
