    Owner since: 6 months
    Price: 60 USD
    User profile: Professional

    Cons: Some chromatic aberration, depending on scene of course; plastic filter threads and hood mount

    Pros: Sharper than other similar zoom from the film era, about 7/10 Very Compact (honor his name UC from Ultra Compact) Internal Focusing

    Summary: Good for students or general non comnercial work if found at good price, I picked mine New for 60 USD shipped at eBay while looking a cheap lens to sell and old DSLR with it, I ended up selling the DSLR with an old Tamron 28-200 that I have, since this Sigma itīs sharper.
