Zacuto Kameleon Micro-OLED Pro EVF Viewfinder, 4K Input with Waveform

Diopter was cracked, but I think that's why there was an extra one in the box. There wasn't an comms. on this so that's my guess.

I’d write a thorough review, however, I can’t turn the viewfinder on because it does not come with a power cable. Hopefully I can find a cable soon because I really want to try this thing out.
