well ive had and sold and have a whole bunch of rf lenses. i was very happy with my 'current' gxr lineup of nikkor 35/2.5, summarit 50/1.5, elmar-c 90/4 and the slr biotar 75/1.5, except i had no wide pov. i had and sold the cv 15 and 25, no offense to anyone, they just didnt suit me. i was kind of down on cv, having also had and sold the 35/1.4 sc. but i took a chance on the 21/4 and wow, am i glad i did! its very tiny for a compact street rig, easily hyperfocused at f8 for 'hip' shots. and i find the IQ of more traditional 28mm just stunning. so here are some samples. most of the street shots were indeed 'from the hip'.
