Sigma 18-125mm f/3.5-5.6 Lens

Pros: Wide angle, 7x zoom range, compact, good build, zoom-lock.

Cons: Slightly soft at edges and corners unless stopped down. My copy has focus misalignment.

The Bottom Line: Optically sharp except for corners at 18mm f/3.5. But mine front-focuses at all focal lengths. Returned in favor of 18-200 lens.

Cons: Its focusing servo is louder, comparatively than any other lens. Pretty loud.

Review: I bought this lens as a replacement kit for my Canon EOS Digital Rebel's EFS 18-55mm lens. The Canon lens is ok but shorted the circuitry when I was caught in a drizzle, shooting with it. So I needed a replacement for a wide angle. As with Canon, all ...

Cons: Manual focus ring could be firmer, motor could be a little quieter.

Pros: price maybe, zoom range

Cons: poor optics very noisy ,very slow operation

Review: this is the worst lens ever made,although its zoom range and price are quite tempting,this lens makes terrible noises and its operates very slowly,the image quality is far from being satisfying by that i mean that is very noticeable quality falloff in ...
