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?


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