To tilt or not to tilt

[Busted Knuckles]

Really? I always thought the TS-E 24mm is one of the sharpest primes around. Bryan's ISO crops seem to support that: http://www.the-digital-picture.com/R...mp=0&APIComp=5
Or does it get softer only when you apply tilt and/or shift?

JRW said it well, just to be clear, locked in the center - yep darn sharp, tilt 8 degrees, full shift and it is soft, but these are at the extremes, any single effort and the lens stands up darn well.
