Please read full description, lens has slow aperture blades. Look at the video. It shows how slow aperture is. 

Lens shows normal wear on exterior. I see some name inscribed on the plastic lens barrel. Front glass has couple tiny scratches. They do not affect image quality. I don't see any scratches on the rear glass. Glass is very clean and clear. I don't see any dust specs inside. No haze or fungus inside. Lens looks OK over all, even thought you can see that it has been used. 

Performance:

Lens has issue with aperture blades. It is little bit slow, it takes maybe 1second to close. So that is much slower then usual. I don't see any oil on the blades, so not sure why they are slow. Other then slow aperture, lens works good.  

Lens comes with free and unconditional 90 day money back guaranty. You can test it, try it, and if you don't like it, just mail it back for a full refund. So you have nothing to loose.
