The Minolta AF 70-210mm was very popular with the old Maxxum film users, and now too, thanks to Sony users. This telephoto zoom is long, but doesn’t extend out when zooming, and has a constant fast aperture of F/4. Currently, Sony has no equivalent lens, the closest lens in the Sony lineup would be the very inexpensive DT 55-200 F/4-5.6, which isn’t for full frame cameras. The color is satin black, shinier than the Sony black. The zoom ring tension is about right to slightly loose in my opinion, and my copy has seen little use. It has a focus distance window, with three infra-red focus index marks at 70mm, 100mm, and 210mm, you don’t see this much anymore. This lens is multi-coated and has the typical older-style magenta cast.
Auto-focusing is a little slow and loud, but seems accurate. Manual focusing takes just over 1/3 turn from Close-in to infinity. The focus ring extends as you turn it, which is part of the lens barrel.
Lens flare/ghosting. Average to below average control, just as distracting (but different) as the Sony 75-300mm. You normally don’t need to shoot into the sun with a telephoto lens, unless taking pictures of the (rising or setting) sun, in which case if it’s dead center, there’s not much of a problem. The hood that came with this lens is plastic.
Bokeh. Smooth over the full range, but a little less so around 70mm, much the same as Sony telephoto zooms.
Color. Similar to Sony lenses.
Close-up filter use is limited to 70mm or slightly longer with a +4.
Regular filters cause no problems on full frame or APS-C cameras.
Filter size is 55mm. Sony uses this size on many lenses such as the: 75-300mm, 50mm F/2.8 macro, 100mm F/2.8 macro, 35mm F/1.4, 50mm F/1.4, 18-70mm kit lens and the 55-200mm zoom.
