Only the EFS 17-85mm on the 40D...
still thinking about, rationalizing & lusting after the 10-22 wide.
I GOOG a specific lens regularly and notice the prices jump
around like oil futures; but any good price comparo site usually
gives the current best price.
I need Santa to bring me that 10-22 "real wide"!
