flare control: 4
|ownership:||I own this lens|
|compared to:||Various Tamron, Sony, Sigma, M42|
|price paid:||150 USD (new)|
|positive:||Very good close focus, good zoom range, small and light; IQ is better than you'd expect|
|negative:||IQ gets flat as you near 300mm, max aperture goes to f/5.6 quickly|
|comment:||Mine is black, not silver. It is a very versatile zoom lens. Both build and IQ are a huge step up from the 18-70 kit lens, although nobody is going to mistake this for a fixed-focal-length prime.|
The main problem is what happens as you zoom long. Maximum aperture becomes f/5.6 really early and contrast seems to go down pretty dramatically as you approach 300mm. Not exciting.
On the other hand, it is perfectly usable, even wide open, and focuses to a surprisingly close distance. It is hard to complain for the price. It also is pretty easy to carry in a small camera bag, so you'll have it when you need it.
In fact, my initial A-mount APS-C kit was a Sigma 10-20, Sony 18-70, and this... and it took more than a year before I added to that set. I still think that's a well-balanced set, just a little weak in the 18-70. Yeah, the Sigma costs more than the other two combined, but ultrawide zooms are optically complex enough that you need to spend some money to get them right.
Update: I'm finding myself using this lens much less since getting a beercan. The beercan's better IQ and f/4 is quickly making this a lens I use only when the beercan is too big or I need 300mm.
Update 7/2015: This is my easy-to-carry up-to-300mm choice, but my 28-200mm Sigma has become the one-AF-zoom choice due to range, size, and IQ. This lens is still fine on either APS-C or FF at 24MP.
Update 6/2023: I've now tried this out on my A7RV with LA-EA5. It's pretty good, although AF and resolution certainly aren't on par with my one-year-old FE Tamron 28-200mm or 150-500mm. The images are pleasantly resolving in the 20-30MP range, which really isn't anything to complain about. What's more strange is that it worked with one of my A-mount teleconverters on the LA-EA5: an AF 1.4X Teleplus MC4. AF hunted a bit more, and detail resolved didn't really increase, but it is an option to give you a 420mm view in a very compact and lightweight package.
