Originally posted by Pentax Syntax I like it! The donut bokeh can be very effective. I know it’s not everyone’s taste but in some circumstances it works.
I agree in this case it fits the picture and I'm sure that the (at least) 500-hand-held-mm helped get this shot. Someone gifted me one a few years ago and I was fairly snobbish including it in my bag alongside legitimate lenses, until a took a few photos with it and was amazed. I got some great at bat photos from centerfield of some of my son's little league games last year. I took a few with it this year and got a very unsettling result.
I think it can be a good tool given the right subject and background.
