the first compact f/1.0 landscape lens
So many of the current Voigtlander lenses work well for landscape.
Infinity focusing on the 50 f/1 at wider apertures takes some thought.
— At f/5.6 or smaller, I just hit the hard stop and focus is perfect across the frame.
— At f/4 or larger, outward field curvature becomes apparent if using the hard stop, and it will leave the center slightly soft and the edges very sharp. Perfect infinity focus on the center and wide open (on my copy at least) is a hair’s width shy of the hard stop I found out. (I think it’s more than outward field curvature, it seems to be a mild wave since mid-field will be even softer than the center.) This is where it gets tricky: f/1 is not enough contrast to be able to find perfect infinity focus even in bright sun, and f/4 is too much DOF. I’ve found f/2.8 to be the perfect aperture to focus this lens to infinity using the EVF. The EVF is absolutely necessary for me — no way to see the small difference with just the LCD without a magnifier of some sort. Anyway, most of the time I will be at f/5.6 and smaller and not have to worry about this.
