Used on Canon 7D (56mm equivalent?) For portraits (indoors) and not requiring a 50mm recoil as I also have (it's a nice bokeh and more compared to the previous version ...) if not also for videos as silent manipulation of the focus ring (also very useful because we can zoom out manually without damaging the engine as on Types L I own) or to travel light (see mode)). That objective may be trying just as the 28 or 40mm cannon ... after everyone will find his account or not. Anyway for those who did not have the first version of 35mm I think his skills are undeniable (optical, F2, the ultra speed of its AF, its image stabilizer and its price keeps falling on AMAZON). Delivered without sun visor but I found a clone of the EW-72 I'll test on receipt ...
