I just received an adapter for an old Summilux lens that unfortunately suffered permanent fungus etching from years of storage in its previous SE Asia home. Using it today I was pleasantly surprised that it was still able to take pleasing images (with shallow depth of field and interesting bokeh)... as long as I avoid images with direct light flaring
