Sigma 70-300 mm F4-5.6 Macro lens for Minolta auto focus film camera body Comes in the original box. Excellent condition. Sony A-Mount DSLRs / SLT Cameras: If your Sony digital camera is an older Alpha DSLR like A900 or A580 with a physical A-mount, these lenses fit natively without any adapter and retain full autofocus and metering. Sony E-Mount Mirrorless Cameras: If you have a modern Sony mirrorless camera (such as the Alpha a7 series, a9, or a6000 series), you need a lens adapter to bridge the gap because mirrorless bodies have a shorter distance to the sensor.
