Hello everybody,
I happened to see these interesting pictures couple of days ago, long after they were posted on the forum, so I retrieved from my hard disk test shots made with my own FED 28F4.5 on a Fuji XE-2. The FED wide-angle happened to be one of my very first "rare finds" when I started collecting Russian cameras years ago... (Since then I did find 2 working FED light meters !)
After close examination the mist in my lens for sure comes from separation of the cemented elements (mediocre quality glue ?). Just for fun, I tried to "de-mist" the pictures using various photoshop resources to add contrast (but no sharpening), in part to try and appreciate what sort of detail level this lens was able to capture. My conclusion is that when new, this lens design must have produced pretty sharp pictures. See the light bulb in the enlarged detail of the "terrasse" pic. Pretty amazing remembering this was a 1930's design, with an incredible (at that time) F4.5 !
First my garden (as is jpeg from the XE-2) :
