Lets get this thread started! I love this lens, for the price its a excellent performer. It has clean and very sharp flat field of focus, great stopped down. It shines at f/4 and more. At 1.8 the bokeh can get a little nervous and it has no real character or personality, so its not for the bokeh lovers. Its not bad though and again, stopped down pass f/2,2 it manages quite well. I use it mainly on a D600 as my standard lens.
