This puts more creative control where it belongs, in your hands. Lens Construction: 7 elements in 5 groups, Angle of View: 5°, Minimum Focus Distance: 33 ft.

Customer Reviews

works pretty well
Nice lens but just like other reviews, I have to agree that it is difficult to keep the lens steady for a good picture. Also, the AF (auto-focus) feature of the camera does not work with this lens. One additional point, be sure to unlock the shutter release in the menu because otherwise the camera won't recognize the lens and will not release the shutter.

Lens almost impossible to clearly focus
I purchased this lens for my A350 hoping it would be at least something to get me by until knew what lens I really wanted.

I would not pay any price again for a lens by this manufacturer.

98% of the photos are blurry even thought they look fine in the viewfinder or LED display. By the time you get them in focus or think you have them in focus, if the subject is not stationary, the shot has been lost...

Spend a little extra money and buy another brand.

Interesting Option
This is not a great lens, but you can get sharp handheld shots with it if you shoot at a high ISO and at 1/500th of a sec or faster. The dork above didn't seem to know that. I hate it when dumb people write dumb reviews when it's not the equipment's fault. This is a bit of a joke when it comes to a photographic lens, and is surely at the bottom of the barrel when it comes to quality, but it's not like looking through a drinking glass or anything. I'd say this is a few notches below kit lens quality. Understand this when buying, and you'll have some fun.
