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.
