Sigma 50-150 2.8 vs Canon 70-200 f4 L, for a 40d Body.
I'm stuck choosing between these two as they are around the same price at £500 ish. I'd gladly sacrifice 2.8 for f4, if the L quality was worth it..fe;focusing speed, bokeh, build etc
I don't suppose anyone here has tried both?
I hear they are both fairly evenly sized for carry around long zoom's.
Thanks R
