I was told end of the month... Canon is usually pretty accurate on their estimates. Of course that is wishful thinking. I have one on order. I had a 70-300 DO and sold it. I actually had two. THe first one i had was terrible. I had one of the first lenses. I sold mine and the person I sold it to months later showed me a comparison with a second lens. As a result, I bought a second lens. The second was clearly better than the first. HOwever, the optics were not as good as the 70-200/4. The IS was outstanding so without a tripod could get better handheld shots with the DO. The DO suffered from low contrast and was soft at the edges on the ff DSLRs. The 70-200/4 and 70-200 L IS are outstanding from an optic point of view. Mark
Just wondering if you've had your hands on one of these yet? I was going to buy the 70-300 DO IS over the 70-200 F4L just to get the IS so this new lens was well timed for me. Will hold off until this new lens is available (can't wait until November) and some reports have filtered in.
