The earlier pictures show a "normal" convex lens at the front. I'd guess yours has been re-assembled incorrectly, maybe by accident or deliberately, for "effect", as is done with Helios-44's to "enhance" the "bokeh-effect". Certainly worth testing it as-is then removing the front element and inverting it to see the differences. |
