Rated 5 out of 5 by from Amazing! for the past 3 months I had been on the tip of the iceberg deciding whether or not I wanted to purchase this glass. Once I saw it go on sale, I suppose it wouldn't hurt to try it out! I have to admit I am impressed. I have been using a 18-200mm zoom lens for all my shots, becuase I thought it'd make a great all around lens. It is, but this lens completely blows image quality comparison out of the water. with the examples I have, I rarely ever see myself changing lens anytime soon. I've been using this lens with a bounce flash and takes the pictures to a new level. I have had no regrets with this purchase and I recommend it to anyone who take pictures of people mainly

Rated 4 out of 5 by from Good lens for the price This lens is exactly what you'd expect. It performs well, especially given the price. Images generally come out pretty well. Limited depth of field definitely adds a nice touch to many issues. The build quality is not the best, but as the cheapest lens in the Sony lineup, I think that's expected. Autofocus is generally accurate and is acceptably quick. The only thing that I would say is that the 50mm f/1.4 lens is a significant step up in build and image quality, especially at the larger apertures - so if you have the extra money to spend, I'd recommend the more expensive lens. Still, at the low price of $150, this is going to provide a very large step up in image quality from the kit zoom.

Rated 5 out of 5 by from 1.4 vs 1.8....Chose to keep the 1.8 Very impressed...for the money you can't lose. I wanted to compare the 1.4 vs the 1.8 because I couldn't I bought both...took shots with low light, also bokeh shots. I honestly didnt' see a difference...I attached some test shots...I returned the 1.4 without hesitation...and kept the 1.8. If you want better build qualtiy and maybe a little little bit faster shutter speed in lowlight..then go for the 1.4, but save money and get the 1.4 because its ALMOST the same minus the build quality and a few hardly noticable diff.

Rated 5 out of 5 by from New SAM lenses are really a step up!! This lens really is an exceptional lens! I bought it while it was on sale this past month and the 1st day I got it I used it for an event I had that evening as a primary lens. I certainly was thrilled by the crisp quality of this lens. For the price you would think it wasn't a good piece of glass but for the price, you're getting a powerful lens that's very crisp and precise. The wide aperture is wonderful for low light situations and certainly is a lens you should have in your bag!! This lens is a must and to have a couple of older lenses before Sony came out with the SAM motor lenses, I can see they've done their homework and produced lenses that are near Carl Zeiss quality and G lens quality!! Thanks Sony for listening to your consumers requests!!

Rated 5 out of 5 by from The best bet for the buck! I can get really great quality pictures with this fantastic lens. The sharpness is exceptional. And the price is as low as it can get. The only problem is the build quality, there is too much plastic but it's excepted when you see the price point. The autofocus moter is a little noisy but you can live with it.

Rated 5 out of 5 by from Great lens I got this lens about 1 month ago and I love it, it's great for bokeh in portraits and for night time shooting. It's a must have lens, I had the 18-55mm and 75-300mm lenses but niether were good for night time shooting so I needed a prime lens like this. I recomend to buy this lens :)

Rated 5 out of 5 by from A Revelation This is a great Lens ive had it on my A350 for an evening and already i know its going to up the ante in my photographic work! the depth of field is as shallow as youd ever need it and the speed gained from that big aperture is just amazing! never thought i'd use anything less than ISO800 indoors without flash! A must have lens for any APS-C Alpha owner.

Rated 5 out of 5 by from Awesome portraits For only $150, this is a great lens. The focus area is extremely narrow so you can et some great affect. Highly recommend.
