Summary: Excellent lens. I own several Sony lenses, which are good, but this one displays a higher quality and performance. I am intending to switch to Carl Zeiss lenses as soon as I am able in all those comparable models that I may.
Excerpt: This lens functions as my primary lens. For an amateur who is just starting to really get into photography, this lens provides an ideal focal/zoom range. Upgrading to this from the kit lens provides an amazing leap in picture quality.
Pros: Consistent Output, Durable, Nice Bokeh, Strong Construction
Excerpt: This is my go to lens. Sharp! Great lens Stays on my a77. Landscapes are beautiful, great with grand kids as can stay far enough back so they are natural. Color is superb! There is no purple fringing and distortion is non-existent when using Lightroom with this lens checked.
Pros: Color, Consistent Output, Fast / accurate auto-focus, Nice Bokeh, Rugged
Summary: The optical quality of this lens is superb. I used to have a sony dsc-r1 with a carl ziess lens and I missed the "ziess" quality which i have not seen in any other lens. This lens is better than my original lens in every way. I have a sony a65 and can't believe the quality of my images.
Pros: superb optical quality.
Cons: could be cheaper. Slightly larger and heavier than plastic lens
