As the title lays out, I'm looking to pick up an 85mm for poorly lit indoor sports. I've been wanting the 85L for a while for portraiture and events. However, 1/3rd of my shooting is for indoor sports at poorly lit venues - school auditoriums, church basements and gymnasiums. Specifically, these are martial arts demonstrations. I've read accounts of the 85L focusing well on the 5D3, but the 85/1.8 is known to focus faster. Otherwise, focusing speed doesn't matter to me the other 2/3rd of the time.
One is substantially more expensive than the other and I don't do paid work. However, I can afford the glass. Any thoughts on the matter?
