Welp... I did it.
The Nikon d300s is gone and a Mamiya RZ67 Pro II is on it's way to me. I got the camera with the waist level viewfinder, 50mm, 110mm, and 180mm lenses and two 120 backs. If UPS tracking is accurate it should be here on Monday. This is going to be a long 5 days, I can't wait to run a roll of film through it.
The Nikon was my last digital camera too so that means I'm now 100% film!
