I have a crop(1.6x) body, coupled with EF-S 15-85mm(excellent walk around lens) and EF 50mm F1.4(very nice portraits from F2.0). The results are quite satisfying, but 50mm is little too long on crop's for shooting a wedding ceremony or group portraits.
So, I am thinking Sigma's 30mm or Canon's 28 or 35mm but I have several questions regarding bokeh, sharpness and FOV.
Can sigma or canon accommodate 10 persons in a row from a distance of 10 feet?
Your suggestions please...
