My A-mount Sony DT 18-55mm f/3.5-5.6 Zoom Lens was the kit lens that came with my Sony a580 DSLR. Nearly every manufacturer has made a lens like this. These lenses are of mostly plastic construction. The zoom and focus are not that smooth. They are great because they are cheap, light, and compact. For the price point, this kit lens by Sony is pretty good. For many photographers, it will be good enough. They might wish for a wider zoom range, but then they would have a longer heavier lens.

I had a similar kit lens from Nikon, and it filled up with sand while shooting in the deserts of Utah. I am not sure if one of their better lenses would have done that, but I am glad it was this inexpensive lens and not something else. I quickly replaced this lens with a Sigma 17-70mm f/2.8-4 DC Macro OS HSM, which wasn’t much larger, or heavier.
