I'm shooting a dance recital......unsure of how to focus with the xl1. Will 'back-focusing' (say on the back curtain) enable me to get good focus on the whole stage, of all the dancers?. I know I need to use manual focus. But the lens doesn't have an 'infinity' setting. I'd appreciate any help on this. Thanks. mweston@airmail.net(posted 8733 days ago)
