Hi, Looking at a used 5d mark iii, and it supposedly has a bg-e20 battery grip with it. I only see the bg-e20 being promoted for use with the mark iv. Does anyone know if this is also back-compatible with the mark iii? Thanks.
That's what I was finding. Thanks for responding and confirming my suspicions. Not sure if the guy is just showing the wrong box or what but need to confirm before purchase. Thanks again!
