I have to say I have never be disappointed from using this lense. It is brilliant. I can shot everything from this lense, a bit of landscaping, a bit of distance shot that I can crop to an actual image size and use it right away. The colour and the sharpness from this lense is the top of the range. Never regret of buying this one.
It seems like a very good lens, but not not as sharp as the ~$200 Sigma 30 mm. If I want more color, contrast or sharpness (which is not needed), you can always add that later in post processing. You can also crop images on the Sigma 30 mm to get excellent IQ and resolution.
If you get the the
Sigma 30 mm instead, you can also get the
Sony 50 mm and
55-210 for the same price. To me, getting those
three lenses gives you a lot more bang for the buck with more versatility and focal lengths for the same price.
