Got that one cheaply for 55 euros. Shot thru window and a long exposure time, f:8 Some dusty jade, rubies, blue spinels and tourmalines, f:8 Leaves after winter, f:8 Last one cropped, noise reduced, contrast added Pretty nice lens and not heavy (610 g). Very solid and mechanically very good. Slow but quite sharp and close focusing (1.4 mm). Maximum magnification 1:2.
