Sony 50mm f/1.8 DT Alpha A-Mount Standard Prime Lens

You Pay: $168.00
Product Highlights
  • 35mm Equivalent: 75mm
  • Aperture Range: f/1.8-22
  • For DT Alpha & Minolta DSLRs
  • Optimized for APS-C Image Sensors
  • Smooth Autofocus Motor (SAM)
  • Extra-Low Dispersion (ED) Glass
  • 7x Circular Aperture Blades
  • Filter Diameter: 49mm

The 50mm f/1.8 DT Alpha A-Mount Standard Prime Lens from Sony may look like a standard prime lens, but being a lens designed for cropped APS-C sized DT-mount cameras, it is actually a short telephoto lens with the 35mm equivalent of a 75mm focal length. The wide f/1.8 aperture, and seven circular aperture blades, provide excellent out of focus, "bokeh" background effects as well as faster shutter speeds for low-light shooting.

Build with Sony's Smooth Autofocus Motor (SAM), the 50mm lens elements are directly controlled by the SAM unit for fast yet smooth AF when you need it most. To reduce chromatic aberrations, Sony also built Extra-low Dispersion (ED) glass into the elements, producing sharper images with well defined contrast.

75mm Fixed Lens (35mm Equivalent)
This bright 50mm lens is a normal focal length that is the 35mm equivalent of a 75mm focal length when mounted onto the cropped APS-C sized cameras it is designed for.
Aperture Range: f/1.8-22
The range of available apertures begin at a wide f/1.8 and continue to a narrow f/22.
For DT Alpha & Minolta DSLRs
Designed for APS-C sized sensors, this lens may be used on any Sony Alpha & Minolta DT-mount camera, depending on your needs and current system.
Smooth Autofocus Motor (SAM)
Designed for fast, smooth and silent automatic focusing, Sony's unique Smooth Autofocus Motor (SAM) technology achieves high torque at low speed with rapid start/stop response. The AF control signals from the camera body are sent to the lens-mounted SAM unit, which drives the lens directly, helping to assure quick and accurate AF response.
Extra-Low Dispersion (ED) Glass
To reduce chromatic aberrations, the extra-low dispersion glass corrects for specific wavelengths of light - producing sharper images with truer colors.
7x Circular Aperture Blades
Circular aperture blades produce smooth, rounded "bokeh" background effects when capturing spot-light sources in your pictures. Because the aperture blades form a near circle at the wide openings used for low-light shots, spot-light sources have a pleasing out of focus effect.

    Use for low light shots indoors. Also use for people pictures. After getting used to the lens, I can blur the background out by setting to f/1.8. Tried using outdoors, but lens is not ideal for scenery: too narrow field of view. Also when outdoors and using a circular polarizer, the sun easily catches the filter and may ruin the shot. Needs a lens hood of some kind, one that will cover the filter. Another annoyance is that you must set the circular polarizer after focusing, since that part of the lens rotates when focusing.
    Pictures are sharp and clear.

    Comments about Sony 50mm f/1.8 DT Alpha A-Mount Standard Prime Lens:

    At first I was skeptical on purchasing this lens because of the mixed reviews! But needless to say I am so glad I bought this lens. It does everything I need it to do and the bokeh is great! I mainly use it to film my YouTube videos and I love how it blurs out the background of my videos! It is also great with taking pictures. It takes a little getting use to because it is a prime lens, so you cannot zoom. But you get use to it! If you're going to be purchasing your first lens besides the 18-55mm lens I would highly recommend this one!

            Comments about Sony 50mm f/1.8 DT Alpha A-Mount Standard Prime Lens:

            I use it on my SLT-A65. It is quite compact and very fast to focus as well. Although I have zooms that work in the same range they are not f1.8 and they are not light or bright as this one. This lens has very few shortcomings that does affect it's functionality. They include, (1) it is plastic light, (2) The focusing ring is not well demarcated, and (3) Canon and Nikon make similar 50mm (eg: Nikon 50/1.8D - $ on BH) that is a bit heavier but works as well as this lens or are even sharper and at the same price point or less they are full frame as well. In case in the future you will move to a full frame camera this lens would have served it's purpose. All the same this lens does what it is supposed to and I am more than satisfied with the job it does.

              I bought this lens so I could get more depth-of-field over the 18-50mm lens that came with the camera, which was also only F5.6. It takes good low-light pics and does improve depth of field. Next purchase should be a 300mm telephoto.

              I purchased this as my 2nd lens and it is wonderful! The picture quality is much more vivid and the f/1.8 allows my images to Pop! Usage is mainly for portraits and outdoor shots. It's a really good addition to your arsenal especially for the price. I gave it 4 stars only because of the plastic build. But other than that, this is a must have!

                  I bought this lens for my Sony a65 so that I could take candid closeup shots of the actors at the local renaissance fair. On the a65 it makes for a powerful but compact 24 megapixel that will work well photographing people in motion in the shady light that covers much of the fair. Size-wise it fits very nicely on the smaller body of the a65, though I'll no doubt use it on my a77 as well eventually. Combining all this with the in-camera stabilization of the Sony cameras provides a level of image quality that is unrivaled by the other camera companies, in my opinion.

                  This lens is awesome. I use it for pretty much everything now. It's fast, sharp and smooth. I'm not huge on the filters being 49 mm since most of the ones I have are 55 mm but it's no biggie. I was a little weary at first seeing how it was on the lower spectrum for prices, but I don't regret the purchase one bit! It does everything it says and more!

                  The auto-focus is a little noisy, but I can live with that.

                  All in all, a GREAT value for your money.

                      Good lens for the price and produces good images. I use it mainly for doing portraits of my family. Only reason I didn't give it 5 stars was the fact that the focus ring is not easy to find or use.

                          I love this lens. Very good in well-lit rooms but also not bad in low-light.Bokeh effect is great!I have not taken it off of my camera since Christmas.

                            I can shoot in ISO 100 hand held in pretty low light on my Sony A200. I don't have to use flash most of the time. I love this lens!

                            This lens has brought another dynamic to my photography. The aperture 1.8 can help set a mood and feeling a higher aperture just can not.
