Hi --
I had a Sony a6400 with a Sony 18-135 lens set to 40mm to shoot my live videos. I just connected a Blackmagic Pocket Cinema 4K with a Sigma 30mm micro four thirds lens.
The Sony lens set to 40mm and, since its an APS-C lens, it should be the equivalent of a 60mm lens. And the Sigma 30mm, since it's a micro 4/3rds lense, should also be the equivalent of a 60mm lens.
But that's not the case. The Sigma 30mm frames me much closer than the Sony lens. It's as if the Sigma lens is zoomed in much more than it should be.
Any thoughts on what's going on? Am I missing something here?
Thanks,
Jamie
