You would only buy it because you like to shoot film. Nice camera.
The camera might be light, but the DDS, light meter,film boxes, tripod and changing bag add a tad more to the package.
It would be a great project to set yourself, the one camera and one lens to work with. I do it occasionally with a Rolleiflex, very liberating and uncomplicated.
No lenses to swop, no chimping, no histograms, no batteries, no endless supply of pictures etc.
Putting a digital back on it is missing the point somewhat.
