I have a C220 and have had it for about 20 years. I used it for weddings in the old days. The 80mm and 135mm lenses have given me great results.
The 135mm is showing signs of fungus around the edges so i'll probably have to replace it soon but it still fires reliably.
I also have a prizm finder that gets little use. I love the WLF for the "live view" properties that I get from it.
