Infrared Perfomance Notes
An extremely high performing wide/standard lens for IR. It has quite a lot of vignetting wide open and the aperture at the front of the lens can be difficult to get used to, but these are common or minor cosmetic issues. This is a small and light lens that's capable of great results in any spectrum and at any aperture. It's not sharp in the corners by modern standards, so pixel peepers need not apply, but it can be picked up for a very reasonable price for full frame mirrorless cameras.
