What this lens is and who it suits
The Sony SEL2870 is a compact zoom lens for Sony E-mount cameras covering 28 to 70 mm. It weighs 10.5 oz and measures 2.88 by 3.38 inches. The variable aperture runs from f/3.5 to f/5.6 with a minimum of f/22 to f/36. Optical SteadyShot image stabilization and internal focusing help keep handheld shots steady.
Installing and common issues
The lens mounts directly on any Sony E-mount body with no adapter required. A 55 mm filter thread accepts standard circular filters. The nine-element, eight-group design includes aspherical and ED glass to reduce aberrations. Dust or moisture can enter if the extending barrel is used in harsh weather because the lens is not sealed.
Who should buy it and who should not
This suits photographers wanting a lightweight everyday zoom for travel or general use on full-frame or APS-C Sony bodies. The 0.19x maximum magnification and 11.8 to 17.7 inch close-focus limit make it unsuitable for buyers who need true macro capability or a constant wide aperture for low-light work.

Questions about this item
How do I confirm the Optical SteadyShot stabilization is active after mounting the lens?
Switch the lens OSS toggle to ON, half-press the shutter and watch the viewfinder image settle; the circular aperture and 9-element construction will then deliver smooth handheld shots at 28-70mm.
What accessories are included and which 55mm filters must I buy separately?
The box contains the SEL2870 lens, front and rear caps, and a hood; any 55mm circular polariser, ND or UV filter is a separate purchase.
Which focal-length version covers both 28mm wide-angle and 70mm portrait on full-frame E-mount?
This single SEL2870 zoom spans 28-70mm with a variable f/3.5-5.6 aperture, giving 75-34° on 35mm and 54-23° on APS-C sensors.
