Hey Noah, Yes, the EF Mount for the Arri Alexa Mini/Amira mount can be shimmed. If your lenses are not lining up, your rental house will be able to shim the (camera) mount for you. Thanks Noah, Hope this helps.
Hi, I've had a Tiffen IRND 1.5 filter recently returned and the filter appears to have a darker center then the outside, almost as if where the 4x5.6 filter tray sits is one tone and the exposed filter inside of the tray is a darker shade. Has anybody seen or heard about this before? When placed in front of a camera, it's unseen, however very obvious to the human eye. Thanks.
