More little details. Since the lenses are so small, diffraction rears its evil head around f4 or f5.6 so I have ND filters to use outdoors. The lens hoods are clever in that they form series-size filter holders when you unscrew them.
Much has been written about the Minox lenses (I'm a Minox user and owner) but these Switars seem to me to be better than the Minox. Of course with the barrel they are physically about 5 times bigger than the Minox lens.
If you are wondering, the diagonal of the Std-8 frame is about 7mm. This is smaller than the Minox frame (about 13mm).
