SIGMA 17-50 mm f/2.8 EX DC HSM Standard Zooms Lens - for Sony

Does what it says on the box.

No vibration control.

Good for out of focus backgroubds and colour contrast

Extremely fast auto focus. I've only used it a couple of times but the build quality is good and the lens works very well.

When you pick up the lens there is sometimes a noise from the elements moving inside, but this does not affect the operation of the lens.

Sharp, well built, includes lens shade,

Focusing is not silent. Not very noisy but too much for video sound.

A solid lens. Clear and sharp image quality. A great alternative to the Lumix/Leica 42.5mm for portrait photography. Excellent value for the price.

Limited in low light level situations.

Quality lens

Abit on the heavy side

A great little walk about lens, well made, great picture quality.

It is extremely sharp and cheap.

All forgiven.

Bought this 70-200 as the equivalent Nikkor is overpriced. I have to say in all comparisons this lens performs extremely well, sharp fast and well made. The only slight issue maybe that it is heavy my partner uses it and if prolonged shooting her...

Great lens
