The MINOLTA AF ZOOM XI 28-105mm lens has a brightness of f/3.5-4.5 and features an MZ/AZ switch function. It is functionally usable. The optics should have little impact on shooting, but there is some minor mold and dust inside the lens. The auto zoom works, but it wasn't great on the a300. I think the gears are deteriorated. It can probably be used in conjunction with manual zoom. This is being sold as junk. Front and rear caps are missing. - Brand: MINOLTA - Model Name: AF ZOOM XI 28-105mm - Maximum Aperture: f/3.5-4.5 - Features: MZ/AZ switch - Focal Length: 28-105mm Thank you for viewing. ※ Search tags #Mirrorless #FullFrame #A-mount #E-mount #a65 7 77 9 99 6000 6100 6300 6500 6600 6700 S R II III IV #Minolta #TAMRON #Tamron #Sigma #Alpha #DoubleZoomLensKit #α77 #α77ii #α99 #α65 #α55 #α58 #α6000 #α6100 #α6400 #α6600 #α6700 #ZV-E10 #ZV-E10M2 #ZV-E1 #MINOLTA #Lens #αmount #A-mount #E-mount #OldLens #FilmCamera #MinoltaLens #AssetValue #PhotographyDescription #Bokeh #ColorDevelopment #Resolution #Sharpness #PrimeLens #ZoomLens #WideAngleLens #StandardLens #TelephotoLens #MacroLens #SingleElement #LensFlare #GhostResistance #Coating #UsedLens #MarketPrice #LensAssets #Autofocus #ManualFocus #LensAdapter #DigitalMigration #SonyαCooperation #α7Series #A-mountAdapter #LA-EA5 #LA-EA4
