General Notes:
1.)	EF-Mount: Arri Alexa (Classic, XT, SXT ... including the Alexa M) cameras ship with the so-called Exchangeable-Lens-Mount-(ELM)-System - which features a round mount base - and a PL mount by default, with Panavision PL and mounts for still photo camera systems being advertised as available on demand (as part of a future-proof open architecture concept). In reality no more than 2 PL mounts (LA-PL-1 and LA-PL-2: 54 mm stainless steel mounts without and with LDS contacts) were produced by Arri themself. So? Similar to the RED ONE for these you'll need to rely on third party adapters, like the PrimeCircle XE-EF (according to P+S Technik not applicable to the Alexa Studio) or a Birger mount. Refer to Still Lenses C/EF > Adapting Lenses > EF to Cine for more details. The only exception within the Arri Alexa family being offered with a natively produced Canon EF mount option is the Alexa Mini, which uses the same exchangeable mount system as the Arri Amira (square mount base plate). It's an electronic mount with still limited compatibility. Supported lenses include the following (probably more to come):
	EF 8-15mm F4.0L Fisheye USM EF 16-35mm F2.8L II USM EF 17-40mm F4.0L USM EF 24-70mm F2.8L II USM EF 24-105mm F4.0L IS USM EF 28-300mm F3.5-5.6L IS USM EF 70-200mm F2.8L IS II USM EF 70-200mm F2.8 USM EF 14mm F2.8L II USM EF 24mm F1.4L II USM EF 35mm F1.4L USM EF 50mm F1.2L USM EF 85mm F1.2L II USM EF 100mm F2.8L IS Macro USM EF 135mm F2.0L USM EF 200mm F2.0L IS USM EF 200-400mm F4.0L IS USM EF 400mm F2.8L IS II USM EF 800mm F5.6L IS USM
