I know what you mean. I got my 35 before my sister in-law's wedding and it proved to be my best lens for that event. (I wasn't the wedding photog.) I had a new found fondness for this classic. Even after purchasing the 17-55, I still thought highly of the 35 as my low light, travel-light lens. Granted, I didn't like is as well as the 17-55 when I needed it in low light. But, it was still my travel-light lens. I put off the 40 for some time because I already had the 35, and it was faster. I thought the 40 was neat, but unnecessary. But, when the winter rebate hit and the price fell to $150, I gave in and ordered it. No offense to my 35 (or my 50), but I think this 40 is the new classic short prime. It will make you forget about the nostalgia for the 35.
