I agree. I just got one a couple of months ago after wanting Canon to come out with something similar for years. I'm sorry that I waited so long to get it. At its current price it's a bargain. It is built like a tank and sharp corner to corner. The CA wide open is most noticeable up close with bright highlights and not really a substitute for a real macro lens, but I'm thrilled with it in every other aspect. I've owned all the current Canon 50's at one time or another as well as others for different camera brands. I wouldn't trade any of them for the Tamron.Anyone who wants a 50 IS should look at the Tamron 45 f/1.8 VC. Sharp to the corners wide open, weather sealed, good VC implementation, quick and accurate AF, and good bokeh. It does have some CA wide open (easily fixed in post) and only goes to f/1.8 (a bit less background blur), but is excellent in every other respect.
