On APS-C format cameras, for which it is specifically designed, the SAL50F18 functions as a moderate telephoto lens (equivalent to 75mm on a full-frame camera) that can be ideal for shooting portraits as well as for framing and isolating areas of interest in broader, busier scenes. Not only can you isolate the desired subject matter by framing, but you can also take advantage of the lens’s large F1.8 maximum aperture and circular aperture design to isolate your subject from the background by using defocusing.The large maximum aperture also facilitates shooting in low light, a capability that is further enhanced by SteadyShot INSIDE™ image stabilization featured in A series bodies.

Photographers often choose a large-aperture 85mm lens for portraits for two compelling reasons. First, the 85mm focal length makes it easy to fill the frame with the subject from a comfortable distance, without getting so close that unflattering distortion occurs.And second, a large maximum aperture works with the medium-long focal length to create beautifully defocused backgrounds, so that the subject seems to “pop” out of the image.The SAL85F28 is just such a lens. But it’s not just limited to portraits. It’s a great choice for any situation where you want a bit more magnification than a “standard” focal length provides.And the fact that it is light and compact means that it’s easy to take along as a second lens.
