Excerpt: I use it with the Sony NEX-FS700 camera. This is great for light light situations and testimonials. The pictures come out crisp and it was easy to change. I keep the Alpha mount connected to the lens so it's real easy to get on and off.
Pros: Durable, Easily Interchangeable, Good in low light, Rugged
Summary: Haven't had this for long, and bought a used copy as well (not thru Amazon - sorry guys!). Bought for use with an A55 to replace my current Sigma 17-70mm (the old style, non-HSM motor version) with which I just was underwhelmed due to a slight softness.
Summary: If you are not a pro photographer, this lens may be overkill, especially for the price. By "pro" I mean a working photographer who gets paid. I have taken this lens on an overseas vacation trip.
Pros: The images are excellent throughout the zoom range and aperture range. The typical Carl Zeiss micro contrast gives the images that "pop".
Cons: High quality glass will always be heavy and maybe cumbersome, but this is the only negative that comes to mind. Keep in mind that I don't do lab testing on my lenses. This is purely based on viewing my images on screen and also viewing my prints. My reason for 4 stars: price.
Excerpt: sharp, fast lens. A little heavy, but image is superb. I got this to use with Sony FS-100 and they have not yet worked out the a-mount to e-mount communication fully, so the iris jumps wide open, then closes as you open up. fine to adjust iris between shots, not while shooting video.
Excerpt: I'm an amateur photographer of 20+ years, starting with 35mm film and now enjoying the benefits of digital. My experience is based on owning Minolta and now Sony SLR/DSLR gear. I currently shoot with an a700 and a900 with various old and new lenses.
Pros: Consistent Output, Nice Bokeh, Sharpness and Contrast, Strong Construction
