Sony 50mm f/1.8 Overview

  • 1Description

Elevate your portraiture with this lightweight Sony DT 50mm f/1.8 SAM Lens for APS-C A-mount cameras. It offers a 75mm equivalent focal length which combines with the fast f/1.8 aperture so photographers can more easily create flattering images with shallow depth of field. Also, it incorporates a Smooth Autofocus Motor (SAM) for fast, quiet focusing performance as well as a minimum focus distance of 13.4". Additionally, it has a seven-blade circular diaphragm that ensures smooth bokeh.

Designed for APS-C format cameras, this 50mm lens will provide a short telephoto 75mm equivalent focal length that is well suited to portraits.
A fast maximum aperture of f/1.8 allows users to work in less-than-ideal lighting conditions and create images with a shallow depth of field.
By incorporating a Smooth Autofocus Motor (SAM) unit into the lens itself to drive the focusing element group, this lens is able to deliver smoother, quieter, and faster performance than coupled systems. Also, it offers a minimum focus distance of 13.4".
Rounded seven-blade diaphragm contributes to a pleasing bokeh quality when employing selective focus techniques.

Sony 50mm f/1.8 Reviews

DT 50mm f/1.8 SAM Lens is rated 4.6 out of 5 by 168.
Rated 5 out of 5 by from Great Lens I just got this lens a couple of weeks ago and I love it! It's a great sharp, portrait lens. I'm using in on a sony a230. I also have the sony 70-300 and the 18-55 and while both of those have their place the 50 1.8 is much nicer for portrait work and it's also great for getting shots indoors or with less light since it can get to 1.8 aperture. Many people have said that it's too fragile and cheaply built, but I don't see any problem with it as long you're not banging it around. The only thing that is a bit of a bummer is that it is a different size/attachment style from my other lenses and so my sun hood doesn't fit on it, but that's not a huge deal.

Rated 3 out of 5 by from Works good Use on a350. Portrait and general use. Sharp images, even on the edges. Front glass is recessed, which sort of gives a hood. But, filters screw-on past the recess on the very front, and therefore need a to get an accessory hood for the filter, which is not offered (get a rubber hood that will grip the outer diameter of the filter). Lens barrel spins at the front (past chrome ring) when using autofocus. Autofocus difficult in low light - must go to manual focus. Very good low light images. Would think most people would use this lens to take indoor pictures of family, without needing a flash.

Rated 5 out of 5 by from So far so good This is my first prime lens. I purchased this because I need a little something more for flower/outdoor/macro nature shots. I've had it about a week and so far it's not disappointing at all. Winter really isn't the season for nature macros but it handles snow and the plethora of light nature has to offer during the day. My low-light evening shots were great too. I was blown away by the focus and the contrast this lens provides. I'm very happy with my purchase and look forward to using this lens heavily in the spring/summer months. I may be an amateur photographer but I've handled many lenses, this lens feels durable not plasticy.

Rated 5 out of 5 by from Light, sharp, bright & very inexpensive 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.

Rated 4 out of 5 by from good for the price i bought this lens for sony NEX7, and attached it with the LA-EA2 adapter. so it works as if it was on an SLT camera. the lens is small and light and feels very plasticy. even the bionet is made of plastic. the AF speed is good, but on certain cases it misses, even in good light. i own a Nikon AF-D 50mm 1.8 which is cheap too, and NEVER had this problem. optically the Sony is quite good - nice sharpness, contrast, bokeh and colors, quite close to the Nikon. for me the DT is OK, but lacks some character and accuracy. for its price it gives good performance, but as i wrote, i had better lenses.

Rated 3 out of 5 by from One of my favorite lenses 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.

Rated 5 out of 5 by from Performs like a $$lens! Perfect for portrait photography and closer shots (not macro) This lens is great at blurring out backgrounds. See attached photo example. I use this lens with my Sony a77 Would HIGHLY recommend. Best value hands down.

Rated 4 out of 5 by from Amazing! 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!
