The lens that stays on the camera, and its aperture tells you how it was built · review
A small, constant-f/2.8 standard zoom for Sony APS-C cameras, with 1,733 ratings at 4.7 stars, sold by Focus Camera for about $499.
The 18-50mm keeps f/2.8 across its range. Kit zooms close to f/5.6 or so at the long end; this one lets in about two stops more light there, which means a lower ISO indoors or a faster shutter.
It runs from 18 to 50 mm. An equivalent focal length is a calculation: it describes the field of view on a full-frame camera. The focal length engraved on the lens never changes. On Sony APS-C, that is roughly 27-75 mm in full-frame terms, the classic standard zoom.
It has no optical stabilization, so a body with IBIS, like the Sony a6700 on our mirrorless shelf, gets the most from it.
Focus Camera sold it at about $499 with 15 units left.

Yes. The aperture stays at f/2.8 through the zoom, which kit zooms do not do.
Not in the lens. Pair it with a body that has in-body stabilization, such as the a6700.
It is a DC DN lens made for APS-C. On a full-frame body it would need crop mode.
At $499, it is the 1 cheapest of the 3 models in this category published here.
8.5/ 10
The upgrade from a Sony kit zoom: small, sharp-rated and bright. Use it on a body with in-body stabilization.
