This lens appears to be unused (like new, seriously). Includes original caps and nc-10 case.
67mm filter size (includes Skylight filter) and it does macro down to 1:3
Minolta is one brand I don't shoot.
I have pics I can email you, but lack the ability to upload/post right now.
I'd love to know more. I was trying to find info online about this lens but Google says the Sigma 75-200mm f2.8-3.5 is an AF lens (available for Sony/Minolta AF cameras) and nothing on a MD mount version. If the lens you have is the AF Alpha mount version, I'd be interested, if it actually does auto-focus on ewer Sony cameras. I hear some do not.
