A Big Aperture Making it
Easy to Capture Great Portraits
At the first look the Sony DT 50mm f/1.8 AF Lens resembles a standard prime, although as it's a DT lens engineered to cover only Sony APS-C image sensors, it should appropriately be thought of as a condensed telephoto lens. Its low cost, layout, and overall dimensions all lead the beginner to start comfortably accessorizing their camera bag, and begin developing an optic library for their photography.
Make a step forward from the standard kit zoom and explore portrait photography using the SAL 50mm lens. It features a big aperture making it easy to capture those great portrait images. The SAL50F18 was one of the initial fixed focal length DT lenses to be manufactured in DT lineup, which is engineered exclusively for DSLRs using an APS-C image sensor. A big basis for the compact, lightweight size is that it benefits from SteadyShot in-camera image stabilizer, built into every Sony Alpha DSLR camera which enables lenses to reduce the excess weight and cost of stabilization devices located inside the lenses.
A lighter more compact lens specifically designed for the APS-size CCD image sensor used in several Sony DSLR cameras. A integrated Smooth Autofocus Motor (SAM) removes the need to employ a mechanical system to the camera body, thus transmitting autofocus control signals and drive power from the lens. Alternately, AF control signals originating from inside the camera body itself are transmitted to the on-lens SAM unit, which directly powers the lens focusing group, helping to guarantee smooth AF response.
Sharp and great color cast! The image quality will make it your go to lens, while you'll only resort to kit zoom lens during those times you are unable to get in close. A given that it's mostly plastic (that's what makes it light), but it is durable and looks great. You'll not be disappointed over the purchase because of the build quality.
Indoor photographs can be captured by hand holding using only natural light because of the big f/1.8 aperture. Indoor shutter speeds using only natural light (without flash!) photographing away from any windows ranges from 1/8 to 1/120 of a sec using ISO 100 through 400. Using higher ISO numbers (which most zooms would need to do to capture similar photos) perhaps would equal the speed, although would have added a lot more noise. The bokeh is smooth. None of that hexagonal junk as seen in other camera lenses.
Everyone should own this lens It is cheap, while the image quality is superb Additionally, the preset focal length requires a photographer to think more about how they composing their images. The laid-back style of zooming in or out to acquire the subject can no longer be done. You must move, and take objects around your subject into consideration. The bottom line is that you'll become an improved photographer, or by chance a frustrated one by having no zoom.
There's already an AF/MF switch on the camera, you don't need another one on the lens too. So, to use full manual focus the lens and the body controls must both be switched.
49mm size filters. Why not the more common 55mm?
It doesn't work on a full frame, although. If you don't have an A900, and do not plan on ever getting one, then it's
Not congruent with 35mm SLR or "full-frame" DSLR cameras
