I have a shoot this coming Tuesday 1/17 with the Alexa Mini and would love to pick up an ARRI Alexa Mini D-Tap Power Cable if someone has one available. Happy to purchase or rent, or if someone knows of a retailer that has them in stock, that would be great.
B&H shows them in stock: https://www.bhphotovideo.com/c/product/1184186-REG/wooden_camera_wc_208600_d_tap_to_alexa_mini.html You could also try Amazon. Or Adorama. EDIT: Not sure if you need the 90-degree Lemo version. The one I showed at B&H is a straight connector.
I ended up using the non-90 degree connector, and it worked okay. When I used a heavier lens the cable ended up getting in the way, but it worked fine on the smaller lenses. Guess I'm picking up the connector...
