  • On a full frame 35mm camera, this lens is sharp all the way out to the edges. 
  • The lens as a slightly different color shift to it. Sort of a blue look.
  • The images, even with the color shift, are stunning and I really like the look.
  • The bokeh is creamy and smooth. No real bubble or circle bokeh.


  • It is heavy. Especially when you add in the helicoid with it.
  • It is easily affected by side flares. I use a really long hood to help.


It is one of my most unique lenses. It really shines in a foggy photography environment.
