I bought this adapter with the idea of using it with the A50/1.4 and K300/4. It looks like it has never been used but some fungus developed through the years. Here are some crops of pictures of the front and rear element. I postprocessed them to accentuate the formations (a bit too much perhaps).
The insteresting thing is I canīt see any effect of the fungus on the test pictures I took at different aperture values with both lenses...
Can anyone suggest a way to maximise the fungus effect when using the adapter with mentioned lenses?
Is it possible to clean this fungus?
PD: apart of this (major/minor?) issue, the adapter looks like new. I attached an uncropped version of the first picture.
PD2: Pictures were taken with M50/4 Macro @ f/11, ISO 80, 6 seg and PP done on lightroom 4
