I second the Velvia. You will not believe your eyes. Do I feel someone in the market for a medium format projector now......
I started out in the Yashica 124G camp mainly because it was put in my hands when I was a teenager. I still love the Yashica but have always wanted any of the Mamiya "CXX/CXXX" cameras. After I saw what was capable out of these medium format cameras, what could be better than interchangable lenses? I am glad you have given us all reason to look at these wonderful cameras again.
Now, go get some Velvia and prepare yourself for your next love affair!!
