Well following in Shaun's footsteps I have purchased the "nifty fifty" except I am a Nikon lady so I've got the AF-S Nikkor 50mm f/1.8G, It only arrived this lunch time so I haven't had much chance but of course I had a little play, I'm impressed so far and cannot wait to get out there and try something a little more challenging! I think this lens is going to be a Cracker!!!
