Pentax HD D FA 24-70mm f/2.8 SDM ED Aperture Series @ 40mm: Snowy Landscape at Dusk, View Towards Big Pine (Pentax K-1 II)

See my Pentax K wishlist at B&H Photo. Deep discounts are seen on Pentax K-1 Mark II and lenses today.

This medium to far distance aperture series shows the performance range of the Pentax HD D FA 24-70mm f/2.8 SDM ED WR at 40mm from f/2.8 through f/11 on the Pentax K-1 II. A pixel shift series was shot but not used due to too many checkerboarding issues.

The issues here are field curvature and peripheral forward focus shift.

Includes images up to full camera resolution from f/2.8 through f/11.
