This is what I consider to be my standard lens & spends the most time attached to my camera. I bought it originally as a lightweight & small alternative to several wide angle zoom lenses I've used over the years, mainly to ease the weight burden while hiking, but also in an attempt to improve image quality. It may not be as versatile as a Canon 24-105mm zoom, or Sigma 12-24mm zoom, but I found I used the zoom lenses at or around 20-24mm most of the time anyway.
It's turned out to be one of the best buys I've ever made for a full frame DSLR. Not only is it small & lightweight but the image quality is noticeably better than the zooms. It's also much quicker to use, focusing manually using the distance and depth of field scales marked on the barrel. Auto focusing on an imaginary point in space (the hyperfocal distance) while the camera's fixed on a tripod is slow and awkward and the distance scales on zoom lenses tend to be near useless for manual focusing.
At 20mm, it fits my vision of the world almost
perfectly. If I need a slightly longer focal length, I can crop
the image on the computer after the event, something I regularly do
(and plan for) to improve composition. If I need to go much
longer, I'll switch to a 50mm lens to save pixels (which I can carry
& still save weight over a zoom).
