I never took my 24 outside - only ever used it in the studio, mainly for food shots. It was razor sharp, and machined like a decent Zeiss, but I wasn't able to optimise it 1) it vignetted far too soon and too much for my liking, and 2) a little too wide for the work I ended up using it for, and 3) my large fingers found it really frustrating to use the small controls deftly.
Settled instead on a 90 mm Schneider TS Makro Symmar f4.5 which you could get in a Canon EF or Nikon mount. It was sensational - big dials, resolution was 50% higher than the Canon and managed whites and tones so well at times it approximated MF in look. Momentarily fooled some very critical Ad Agency Art Directors!
