Sigma dp3 Quattro Aperture Series: Green Barn

Get Sigma dp Quattro at B&H Photo. I am a fan of the Sigma DP Merrill line which as this was written is 22% off on Sigma DP Merrill.

See also the review of the Sigma dp2 Quattro and review of the Sigma dp0 Quattro.

The Sigma dp3 Quattro is the longest focal length range of the Sigma dp Quattro line. Its 50mm f/2.8 lens is equivalent to a 75mm f/4 on a full frame camera.

This demanding target offers very fine details along with a flat (planar) target. It is useful for showing any/every weakness of the lens.

This is mainly an assessment of lens sharpness across the aperture range, but also discusses distortion and vignetting.

Entire-frame images at sizes up to full resolution from f/2.8 - f/8. Also shown are the Sigma Photo Pro processing settings.
