This summer,I tried the Tungsten 64 with my Pearl River P35 camera. This black beauty is supposedly powered by a cell, however, if the electric system doesn't work (like mine), the shutter is fixed at 1/60 sec. The focus and apperture is all manual. The focal length is 35mm. The coated glass lens produces quite nice fotos in my opinions. It's small like an LC-A+ and quite heavy ... ^..^
