Voigtländer Ultron 2/40 vs Konica Hexanon 1.8/40 on Sony A7R2
The lenses
Lens | Mount | Design | Aperture blades | min. Focus | Length | Weight | Filter |
---|---|---|---|---|---|---|---|
Konica Hexanon AR 40mm F1.8 | Konica AR | 6/5 | 6 straight | 0.45 m | 27 mm | 140 g | 55 mm |
Voigtländer Ultron 40mm F2 SL II | Nikon AI-P | 6/5 | 9 rounded | 0.25 m | 37.5 mm | 260 g | 52 mm |
As far as I know, there is only one version of the Hexanon.
There are two versions of the Ultron: The older one I'm testing here, and the newer SL II - S optimized for digital.
The lens designs are very similar: both are modified Planars, where the first negative group has been split into two. The Voigtländer has an aspheric rear element, and shows the typical onion rings in defocused highlights:

Scene 2 edge - Coma
The Voigtländer shows less coma, but also seems less sharp here. This is probably the result of greater field curvature, because in contrast to scene 1 I focused on the center.
