Aperture Series @ 80mm: Wyman Cabin
These aperture series intentionally uses a 3D subject to pin down both performance and any optical asymmetries across the frame.
Wyman Cabin @ 80mm
Adobe Camera Raw 9.7.0 (668): Camera Profile=Adobe Standard. Built-in lens profile eliminates lateral chromatic aberration (red/cyan color fringing). Chromatic aberration is corrected via an embedded profile, enforced by ACR. Apertures f/9 and f/13 were sharpened to counteract diffraction.
Vignetting is mild at f/4.5 and nearly gone at f/6.3.
Focus was on the orange vertical boards just above center and towards the right side. Results are lackluster until f/9, with a troublesome symmetry issue: the left side near the cabin never gets sharp yet the far distance sharpens up nicely even as the right side is blurred in the distance (as it ought to be). This is obvious even at the reduced size of 4320 pixels, and even at f/13 the left/right asymmetry can be seen in the distant hillside.
