Compared vs Nikon 28/2 AIS, Voigtlander Color Skopar 28/2.8 SL II (Cottonwood Canyon Fall Color)

The brightness for all lenses was matched precisely at ƒ/5.6 (exposure compensation, push or pull). The other apertures for each lens were then match to the ƒ/5.6 frame, again using exposure compensation. This facilitates assessment without perceptual traps.

The Voigtlander lens was a consistent 1/3 to 1/2 stop darker than the Nikon 28/1.8G at the same aperture on this and other comparisons, which means that its T-stop is notably lower. The Voigtlander 28/2.8 is likely closer to T/3.5 at ƒ/2.8, with the Nikon 28/1.8G closer to T/2.8— quite a shutter speed difference when the light is marginal.
