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.

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.

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.

The Sony 50mm f/1.8 DT Alpha A-Mount Prime Lens was a nice affordable addition to my kit lenses. It performs great in low light situations and provides great clarity as well as awesome shallow depth of field. Focus ring is very smooth and the auto focus is very fast.

Great bokeh, awesome value. The one negative this about lens is that if you film with your autofocus on, the autofocus will be heard in your videos. Other than that it's excellent for shooting photos or doing manual video shots

Comments about Sony 50mm f/1.8 DT Alpha A-Mount Standard Prime Lens:
It is too early for me to give any more than a three star as I had expected this lens to be clear close subject and blurred background. I thought it was a prime and maybe I don't understand prime but I thought it would be only 1.8 but I am getting camera info which gives larger numbers. Anyway, I will practice more and try to understand what is going on.
There isn't a lot of info on the internet for this sony lens, so I am kind of in a quandry.
If anyone has info, please let me know.
Thanks.

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

Comments about Sony 50mm f/1.8 DT Alpha A-Mount Standard Prime Lens:
First off, I was very excited when I purchased this lens. My photography instructor advised me against buying this, but I did not listen. I did get some really cool shots with it. However, the auto focus was really horrible. It could never seem to lock in and focus on anything, and when it did it was very finicky (sp) and took forever to find a focus. After having it for only a couple of months, I noted that it was completely dusty inside, and none of my other lenses have ever had that problem (even after years of use). It is made of all plastic, including the mount, which makes it very chintzy and cheap. I wish I had spent my money more wisely... though, at the time, it was $125, and the price has gone up since I bought it in 2010 (from B&H online). Weird, but true. Anyhow, I would not recommend this lens, even if you are on a tight budget. When you cut corners, you risk it being a mistake. This is a prime example of that. You get what you pay for.
