Sigma 20-40mm f/2.8 EX DG Aspherical review by RRJackson

 

This lens is something of an anomaly. Nobody else that I'm aware of makes a lens that covers this particular range. The closest thing I can think of is the Olympus 11-22mm (which with their 2x crop becomes a 22-44mm). This range of focal lengths is...

Excellent optics, very useful range of focal lengths

Screw-drive. Large 82mm filter threading

Sigma 20-40mm f/2.8 EX DG Aspherical review by ray_lam5

 

Having owned this lens for a year now and having read all the reviews posted on other sites I feel this lens has been overlooked somewhat due to it not being designed for an aps-c sized sensor.

Sharp at all focal lengths, little distortion at 20mm , excellent build quality

Soft wide open, quite big

Sigma 20-40mm f/2.8 EX DG Aspherical review by Josstover

 

I bought this lens after selling my nikkor 18-70 kitlens and I did not regret it. It produces clear and sharp images, vivid colors. Little barrel distortion at 20 mm which can be corrected in PS easily. The only problem is chromatic aberration,...

Build, Sharp, minor distortion

Big and bulky, CA
