I have a mint, sharp 45mm TS-E that I would like to trade for a similar condition 24mm TS-E. While the 45mm is faster at f/2.8 and is generally acknowledged to be sharper than the 24mm, I just bought a 35L and am looking for a wider TS-E lens to use for landscape and architecture shots.
If anyone is interested we can exchange pics, more info., etc.
