You are ablsoutely correct.. but the prism also has an accessory magnifyer which is a very handy tool if you can find one at a reasonable price. They are amazing and once you try it, you will never go back to anyting else ever again. Oh and you will miss it on other cameras if you ever switch.
Will this insanely expensive little thing give me a full/mostly full frame view? And will it fit on an NC2 finder?
