SIGMA 15-30mm F3.5-4.5 DC lens, Nikon compatible. I am a camera novice, please judge from the images. Overall it's clean, but someone who knows about lenses looked at it and said there's dust and haze inside, so I'm selling it as junk. Would be suitable for someone with knowledge and skills, or for a collection. Shipping will be in a dedicated case, wrapped in protective material, and then boxed. I will answer questions to the best of my ability, so please ask any questions in the question box. - Brand: SIGMA - Model Name: 15-30mm F3.5-4.5 DC - Maximum Aperture: F3.5-4.5 - Compatibility: For Nikon - Focal Length: 15-30mm Thank you for looking.
