So, I bought a 50mm f/1.8 Series E lens a few months ago for making low light photos. It is a great, sharp, sturdy little lens. The only problem I have with it is that it produces an undesirable and distracting out-of-focus blur. Here are some examples of what I mean: As you can see, any reflections or light sources in the background have a distracting outline around the blur circle. How does this compare to the newest 50mm f/1.8 AF-D from Nikon? Can someone post some samples displaying the out-of-focus blur characteristic?
