I find myself choosing the extremes of my equipment. I went shooting on Cumberland Island, Georgia this past weekend and took the 8x10 to shoot the landscapes and the 35mm to shoot the wild horses. I seldom shoot with any of my 4x5s or any of the roll film cameras. I do sometimes use my 2 1/4x3 1/4 Speed Graphic as a view camera.
I'm with Don. Sometimes all of these cameras are a burden. And we won't mention the typewriters.
