I use a 5D setup, 17-45, 24TS, 35 Olympus PC, 45TS, etc. and a complete 4x5 outfit 47, 65, 90, 150 etc. with the ability to scan in house. Stitching solves many problems that a wide lens will not cover, but is a last resort beyond a two image stitch because it is not very cost effective, time wise, on usual AP budgets.
