Sony FE 24-105mm F4 G OSS is an Auto Focus (AF) Standard Zoom lens with 35mm FF max sensor coverage. When mounted on a 35mm FF sensor camera, it will give you an FF equivalent focal range of 24 - 105mm. With a max aperture of f4 at 24mm, we can not consider this lens fast on wide end but f4 at 105mm is not too bad for tele end.
