If so, that will happen on most large aperture lenses wide open. It has to do with the angle of the light is coming in. Take your lens, look at it off axis (like 25-30 degrees off) and note that you can't see the full aperture because of the angle. That will probably happen with almost any fast 50 you shoot with. If you are talking about the bright ring on the outer part of the out of focus highlights, that has to do with lens design and another fast 50 might work better for you. The Zeiss 50/1.5 might satisfy you. I think it has to do with correcting spherical aberration, which the Zeiss has a lot of, so it has smoother out of focus highlights (behind the plane of focus). It also has focus shift :) I assume you were joking about bokeh being the cause of the lack of view on the Guy picture :) I personally like that one more and wouldn't have really noticed the bokeh, since you have good lighting and good composition in the photo. 'Distracting' bokeh is only distracting to me when it is the subject of the picture.
