This is a CANON zoom lens, the EF28-135mm F3.5-5.6 IS USM. The autofocus and image stabilization still work. I had the front element cleaned for mold, so the mold inside is gone, but some traces remain, although they don't affect the image quality. There is some dust inside. Please note that this is an old lens, so it is sold as-is, with no returns. I'm starting the price low, so if the price doesn't suit you, please look elsewhere. I will not offer discounts. How about it if you want to try it out? Other features: Includes lens hood.
