Summary: Couldn't be happier! I was looking at wide angle lenses and got stuck between 2 sony lenses (one of which was a carl zeiss. Im too lazy to look them up :P). So I went to my dealer who only had this lens in the wide- angle section, and i'm glad i chose it. It had a discount so i can't argue over the price. Quality is pretty good, with almost no noticable barrel distortion from what i've seen, and I also haven't seen any chromatic abberation or what so ever yet.
Summary: I use this lens a lot, mostly for real estate/home interior shots. I purchased it specifically to get some great shots of a home theater that we submitted for an award, and have used it in nearly every home installation that we have done since. It has great color, and you never run out space to fit an entire room into a shot.
Pros: Great color, Decent speed, Good optics, AMAZING width in shots, Lightweight
Cons: A touch slow in low light, size of barrel makes flash shots hard
Summary: Using this lens with the alpha55 I was able to capture high quality images under both interior and exterior lighting conditions, Unlike the earlier reviewer, I did not experience any edge-related chromatic abberations. Most recommended.
Pros: Sharp, vivid colors under a wide range of lighting conditions, good value for the money
Summary: Smooth focus. Light weight. The length does create some shadowing with the on-board flash. Utilizing a hot shoe mounted flash resolves this issue. I specialize in architectural photography, so this lens will be very handy. Wide enough, yet manageable to avoid distortion issues.
Summary: I USE THIS LENS MAINLY FOR NTURE,BECAUSE I LOVE THE GREAT OUTDOORS.THE RANGE OF IT IS TERRIFIC,I ONLY CARRY THREE LENS TO COVER A LARGE RANGE OF FOCAL LENGHTS.I LIKE THE SMOOTH ZOOM,AT THIS POINT I HAVEN'T FOUND ANY FAULTS.
Pros: Consistent Output, Easily Interchangeable, Lightweight, Sharp Focus, Strong Construction
Summary: I used this lens on my Konica-Minolta 5D during a photo workshop with Arizona Highways magazine to the Antelope Slot Canyons near Page Arizona. Since shooting inside dark slot canyons sometimes only as wide as your shoulders made it difficult for photography. But the SAL-1118 performed amazingly giving me wide extremely sharp fully defined depth of field photographs. I can't say enough good words about this lens.
