Sony E 10-18mm F4 OSS is an Auto Focus (AF) Wideangle Zoom lens with APS-C / DX max sensor coverage. When mounted on a APS-C / DX sensor camera, it will give you an FF equivalent focal range of 15 - 27mm. With a max aperture of f4 at 10mm, we can not consider this lens fast on wide end but f4 at 18mm is not too bad for tele end.
This lens features on optical image stabilization which helps capturing sharper images at lower shutter speeds. Sony E 10-18mm F4 OSS is not a weather sealed lens, so you have to be extra careful against rain and dust.
