Ernst Leitz Wetzlar Hektor 135mm F 4.5 M Mount

This 135mm f/4.5 for the M bayonet rangefinder cameras has no distortion, very even exposure and superb bokeh, but is not very sharp except in the center. It's a lens that's great for people shots. It's best to forget this lens if you need super sharp results, but for portraits with soft backgrounds, this lens is great. It has a 15-blade diaphragm for perfectly round apertures at any setting. This lens works perfectly on any Leica and M version.
