Fotocamera reflex vintage Nikon EM 35 mm in bundle obiettivo 80-200 mm f/4,5, borsa, flash 550 FD

This eBay listing is for a used/vintage Nikon EM camera lot that comes as you see pictured in the listing and noted above. The camera is marked with Nikon EM from Japan and the lens is marked with: 1:4.5 f=80-200mm 52 PMZ 280 Multi-Coated J/525 (Made in Japan as well). I test fired this 10x with no problems. When looking through the view finder I see a circle within a circle within a center circle that is divided in 2. Outside of all but the center circle has a matte color that isn't allowing all of the image to come through - it's like looking through a thick fog. Darker images are hard to see and lighter images you can make out. I'm guessing it has something to do with a setting or the lens itself.
