Short Encounter With Panasonic Lumix 20mm F1.7

I wanted a prime lens for my Panasonic Lumix GM1 camera and, the length should be too wide nor too far. Did some research and found out there were 2 options for me, one is Olympus 25mm f/1.8 which is slightly longer in size and the pancake size Panasonic Lumix 20mm f1.7. To be honest, I like them both and it was quite difficult to find used one with good price in Carousell. I've been searching for either one every single day until I found one at rather cheap price SGD180. After reading the description so on, found that it was a good deal and contacted the seller. He mentioned the lens was good until I found out the lens had fungus grown in the lens and I returned the lens to the seller. The pictures taken were some how with dreamy feel as covered by another layer.

The lens is usable and image can be edited to look brighter and sharper or the expensive way is to clean the fungus away which is not reasonable to me. I managed to take some photos with editing done.
