The sort of thing I can never resist.

Cockeyed. 5D, 20mm, 1/3000, f/8. ISO 250. Processed in Lightroom and PS CS2/Image Align

ImageAlign was used to correct the converging verticals, as this was taken looking up with a very wide lens on the camera. I’m hardly head-over-heels with the Canon 20mm, but having all that automation in preference to a superior but manual adapted Leica or Zeiss optic really makes me want to make this lens work.
