flare control: 5
|ownership:||I own this lens|
|compared to:||Sony 18-55mm, Sony 50mm f1.8, Minolta 24mm f2.8|
|positive:||Very useful zoom range and an excellent replacement for the kit lens. Constant f2.8 is very useful.|
|negative:||Corner vignetting, bokeh is a bit busy. Image quality drops off at the focal length extremes.|
|comment:||This lens is an excellent upgrade from the Sony 18-55mm kit lens and compares very well against the CZ 24-70mm (especially for the price). The wide end is useful. Focusing seems pretty accurate and fast although screw-driven.|
There is a bit of corner shading that is noticeable when shooting brick walls and the like. The bokeh is busier than I would like but fine for a zoom. The Minolta 24mm f2.8 has a better bokeh. The 17mm and 50mm extremes are somewhat distorted so having some kind of 50mm prime is useful if IQ is very important.
This lens is great for intimate and small events (small group outings, family get togethers) where lighting ranges from moderate to full sunshine. Not so good for large landscapes or concerts.
I like this lens for the convenience and value. I primarily prefer primes but don't mind switching to this lens when I may need flexibility of zooming.
