Product Description:
This super-wide-angle lens is ensured minimal light-fall-off with superior peripheral brightness. The iris diaphragm has 9 diaphragm blades to obtain beautiful out of focus images in the foreground and background. This is an ideal DG lens optimized Digital SLR camera.The minimum focusing distance of this lens is 20cm (7.9 inch) and it has maximum magnification of 1: 4 with fast F 1.8 maximum aperture. The minimum focusing distance of 20cm (7.9 inch) and 94.5? angle of view allow close up photography surrounding the photographic subject.The lens incorporates Dual-Focus (DF) mechanism. It is easy to hold the lens, since the focusing ring does not rotate during auto-focus, yet it provides adequate focusing torque of the focusing ring during manual focusing of the lens. The rear focus system eliminates the need for the front of the lens to rotate, thus allowing the use of a "Petal-type hood", which is superior light blocking effect.The use of aspherical lens elements in both of the front and rear lens groups effectively compensates for distortion, spherical aberration and astigmatism.

Average Rating:  out of 5 stars

Rating: 4 out of 5 stars - OK for the price
Not great wide open, barely usable at low light. But still, something is better than nothing. Canon 50/f1.4 is far better wide open. But I can't get much of a shot sitting across from a restaurant table, there this Sigma comes to rescue. This lens is otherwise well build. Just that I wish it's better wide open. 1.8 is so much better than 2.8. In regular household light, 2.8 is not very useful unless the subject is completely still. I kinda expected this lens not to be sharp at 1.8 wide open. But ... Read More



Rating: 4 out of 5 stars - Not bad, but not great
Tried three copies of this lens. Great specifications. Nothing else is this fast at this width and this price. The image is acceptably sharp wide open, but only just -- definitely nothing like Sigma 30mm 1.4, which beats this lens hands down in everything but the width.

Good lens if you are a photojournalist and need to print small images at low resolution. Then pixel sharpness doesn't matter much. But if you are a pixel peeper, beware.

The lens is well built, and ... Read More



Rating: 5 out of 5 stars - Superfast wide angle at affordable price
This is my fifth Sigma lens, and I couldn't be happier with it. Because of it's f/1.8, don't expect much depth of field when shooting wide open. Especially in close ups, that's the trade off for low light capability. This lens has opened up a whole new world of possibilities for me with indoor photography when a flash is inapppropriate (performances, candids, etc.). The wide angle is not so extreme that I have to deal with distortion at the edges, but in close ups it creates a different perspective ... Read More



Rating: 5 out of 5 stars - Great budget wide lens with f/1.8
This lens is definitely not a Canon L-series lens so don't expect perfection with it. I bought this lens used mainly for the wide frame and incredibly low fstop and I'm very happy with it. It's a great lens for the money.

I usually only travel with my Canon XTi/400D and Canon 50mm f/1.8 budget lens, but I've really needed a wider lens for getting everything I want in my frames. This lens is perfect as my walk around lens for any available light in night or day.

For my travels ... Read More



Rating: 5 out of 5 stars - Absolutely fabulous images
I've had this lens for three years. It takes absolutely wonderful portraits. If you want to see someone as you have never seen them before, take a full frame portrait shot of them using a Canon 10D or 20D with this lens. Gorgeous.

The lens rounds out such shots just slightly and really enhances facial features. The effect is almost like a very mild fisheye. I have used this to create some of the most compelling captures of the human range of facial expressions that I've ever taken.

Highly ... Read More
