Pentax HD FA 50mm f/1.4 SDM AW Aperture Series: Backlit Bristlecone at Sunset (Pentax K1 II)

See my Pentax K wishlist at B&H Photo.

This aperture series shows from f/1.4 through f/13 puts the Pentax HD FA 50mm f/1.4 SDM AW into a tough shooting situation, taxing its flare control and contrast, and color correction. Observations are made on why a really highly corrected lens is preferred versus just “good” correction as in the Pentax 50/1.4.
