I have been doing a few nightclub shoots lately (things like ISO3200, 1/30 @ f/1.8, so quite dim). Most of the time the lens I have focusses well on my 20D, but sometimes it goes hunting and racks all the way to close-focus, which makes it difficult to see anything in this light. I'm normally chasing a particular moment so I just refocus manually (roughly) to give the AF a helping hand. Of course, this lens doesn't technically have FTM but it doesn't take much to force the AF motor, so I don't feel bad about doing this (especially not on a $80 lens).
How much better (ie faster/more reliable) is the AF on the 1.4? And how does the 1.4 perform wide open? My 1.8 seems to be a good copy, and when the focus hits, the razor thin plane (at f/1.8) that is in focus is tack sharp. So what comparisons can people give for these two in terms of AF? ------------------------------------------------------------------------ ----------------- You lens is good but the 50mm F1.4 does focus faster and the additional 2/3 stops will help reduce AF. It also the only lens in the EF System to combine the extra-small Micro USM and still provide full-time manual focusing when the lens. It also has better bokeh, or background blur, that the 1.8 II both wide open and as you stop down due to the 7-bladed iris v. the 5-bladed on the 50mm F1.8II.
