I'm very happy with my 150mm f/5.6 Componon. Yes, it's an enlarging lens, but I've never seen a negative where I felt I was losing sharpness by being in much further from the subject than the baseboard normally would be. As a bonus, if I unscrew the front group, it becomes a 250mm f/13, still with good image quality (pretty much only useful in bright daylight, though, due to the dim ground glass image). Two lenses for the price (and weight) of one. Also helpful that the same lens boards fit both my Graphic View and my Speed Graphic (though I have the Speed's rangefinder calibrated for the 13.5 cm f/4.5 Tessar in an empty shutter shell, so I have to focus on the ground glass if I mount the Componon).
