Buy the Zacuto EVF Flip through this link and support EOSHD.com!
The Zacuto EVF is the first new generation DSLR accessory that is truly killer. It benefits DSLR ergonomics so much and monitoring is a different world with it. Peaking, zebras, anamorphic, you name it. Also with the latest firmware it has audio monitoring via the HDMI loop through and on-screen levels. That is good news for the future (at the moment DSLRs don’t output audio whilst recording) and it means any absence of a headphone jack on future DSLRs won’t even matter.
