Fungus ~ Nikon Nikkor 35-105mm f/3.5-f/4.5 zoom before/after

I wanted to see what effects fungus infected lens elements might have on resolution and contrast.  On hand was a Nikon Nikkor 35-105mm f/3.5-f/4.5 zoom that was somewhat infected.  It wasn't too bad, but still, I thought even a little should affect the outcome.

Setup -
  • Sony A6000, 100ISO, AWR converted in Sony's software 
  • Big Beefy Manfrotto tripod 
  • Nikon Nikkor 35-105mm f/3.5-f/4.5 zoom
    • Straight-thru adapter
    • Lens Turbo II adapter

Here's a look at what fungus there was in the lens before a proper CLA.

There's not much to say.  I can't tell any difference between the pre and post-CLA'd lens output.  This is a case where fungus had little to no effect on image creation.
