Tell me how you like the lens. I'm between camera's at the moment - one friend bought mine and I'm buying one from another friend, but I have used a 50mm prime a couple times before. I've used the 50mm 1.8 MK I (though, like I said, same GLASS as the MK II), as well as the 50mm 1.4. Quality is somewhat better on the 1.4 but not worth the price difference. The 1.8 is a great lens. You'll never see a f1.8 aperture lens for near that cheap anywhere else. The low-light abilities at that aperture kick the *** of the low-light abilities of the kit lens so many people use (which won't go below f3.5 at it's widest focal length and won't go below f5.6 at it's longest focal length

) - that was a mouthful. The sharpness of the lens and color is like many prime lenses, far superior to many zoom lenses, especially the kit lenses. Some find that the lens is a LITTLE soft at 1.8 (though most the people with that complaint are high-end photographers used to Canon L-series lenses) - you may think it's plenty sharp even there, but decrease the aperture a little into the f2.Xs and it'll be moreee than sharp enough.
Be sure to let me know how you like it!
