what that guy said!
I'm not certain that a better MF for shooting macros has been conceived than the SL66. Made in Germany, formerly costing as much as a VW, now quite reasonably priced with affordable ($300-500) Zeiss Oberkochen lenses.
I own one with a Bill Maxwell screen installed, three film magazines, 45 deg prism plus WLF finder, and the 50-80-150-250 lenses. Its my main nature photography camera. Basic lens tilt has bought me 2-3 extra stops on many occasions that would leave the Hassey shooters blurry in the wind stopping down.
