On my 5DMKII I find that in very low light the lenses hunt for focus (50mm 1.4 + 85mm 1.8). I don't want to use flash, but will the red focus beam improve focus speed and accuracy? Switching the flash off and keeping the beam active?

Anyone using this?

thanks

Agree with Apewithacamera. I do it occasionally as well, with very good results.
