Where to this lens and how much does it cost? Considering of upgrading my film SLR... think even the Canon 500D at IT show beats professional film colours and resolution... but dun think can find this lens in IT show... maybe it does not go well with 500D? Zoom from 24-105 is really convenient... If buy EF-S lens, cannot use on film cameras, so sad...
Agreed this is a good walk around lens but bear in mind that 500D is using 1.6x crop sensor so instead of 24-105mm it will become 38-168mm may not be wide enough for shooting landscape or indoor group photo.
