yes, I agree with that. and it's better if Canon will upgrade 135 2.0 to a IS version. also $4K is a lot of money, you can get a 300 2.8 or a nice body(3D maybe?)with even better high ISO performance in few years good enough to off set that difference between 2.0 and 2.8(just for the same shutter speed), and as always, if you want the best IQ and have the money to burn, go with the best you can get.
