IRIS control issue workaround
Posted: Wed Apr 03, 2013 6:16 pm
Not positive this will work for all the non-working EF lenses, but we have discovered a workaround for our particular lens.
We use the Canon EF 24-70mm f/2.8L II USM Zoom Lens.
Our lens was not working.
We purchased the Bescor BM-EPIC Battery & Charger for the Blackmagic Camera.
We discovered when the battery pack was in use, we had IRIS control! Also found that as long as we have external power to the camera that the IRIS worked just fine as well.
So thought we would pass this along for anyone else in the community that may be as frustrated as we were at not being able to use our best glass for things, and hope it works for other lenses as well.
If you have a different lens, and this fix works for you, reply with your lens, and I will start adding confirmed lenses that this workaround works for!
