Recently got a 40mm pancake lens for my canon which means I don't have to wait to borrow the fuji x100 I've been goofing around with.  I admit I naysayed the lens when it came out but now that I have been using one I'm in love.  It's by no means suitable for serious work but it makes having my camera on my a lot more convenient and enjoyable.  It's been particularly JAWSOME for goofing with my puppy.
