60MP Sony A7R IV
Sigma 45mm f/2.8 DG DN Contemporary

Aperture series at Close Range: Orange Flower

This series from f/2.8 to f/11 evaluates the Sigma 45mm f/2.8 DG DN near minimum object distance (MOD) of about 1:5, which is near-macro range. Some lenses are not as well corrected at close range and the callout as a “bokeh lens” by Sigma suggests that this might be the case. How well does it do?

Includes images up to full camera resolution.
