I received my new Canon EF 85mm f/1.8 lens last night. Thanks to Amazon, American Express, and UPS!
I have not had much time to get out and really put it to use, but I've been playing with it, and so far I'm very happy. I crank it open to f/1.8 and up the ISO on my 40D to 800, and I can take nice shots in very dim light.
Also, the big aperture makes for a razor thin depth of field, which can be put to good use in many circumstances. Portraits and similar are perfect for this lens.
Keep an eye on my Zooomr site for more shots with this great lens!
