Description

In-Depth Review
The Sigma 150mm f/2.8 EX DG HSM Macro Lens delivers excellent image quality in a relatively long focal length (for a macro lens) at a very reasonable price.

The image quality a lens is capable of presenting to the camera’s sensor is typically the biggest concern I have with a lens. Will it deliver the results I desire? The Sigma 150mm f/2.8 EX DG HSM Macro Lens quickly erased this concern for me. This lens is quite sharp with a wide open f/2.8 aperture – from the center all the way out to the full frame corners. Stopping down improves image sharpness only modestly, but it is usable wide open.

Most other Sigma 150 optical qualities are also good. CA (Chromatic Aberration) is well controlled. Distortion and flare are not issues. Color is fine.

Vignetting is the Sigma 150’s weakest image quality factor. Even stopped down to f/8, full frame users are going to see over 1 stop of shading in the corners. Users of 1.6x bodies should be happy at f/4 and beyond. This light fall-off may or may not be an issue to you. It will be most-noticable if you have an evenly-colored subject or background extending through the darker outer portion of the image circle (image corners).
