This wedding, last Friday, lit by candle light, was pushing the limits of hand holdability, even at ISO 1600, f/2.8, I was shooting a 200mm focal length at 1/30th shutter speed.
Subject movement at 1/30th of a second is a borderline problem with people who are kind of holding still or moving slowly, at a wedding ceremony.
Yes, I know what bokeh is.
I think my 600 f/4 has better bokeh than the 85 f/1.2, but it is hard to be sure, because the DOF is so incredibly shallow that the background is usually completely blurred.
The 24-70 actually has pretty nice looking bokeh. My 50 f/1.4 also has nice bokeh.
