Canon also recently released the RF 50mm f/1.8 STM. When paired to my R5, it makes for an compact and light weight combo with longer reach than the RF35 f/1.8 IS STM. Honestly, my EF L-primes and L-zooms are tucked away in a 1510 collecting dust these days.
I meant to further explain...
After watching Kendy Ty's videos, I've dusted off my 60D and have been shooting tests, following his basic workflow of using the VisionColor picture profile, a basic grade in post, and adding S35mm scanned film grain on top.
I've been shooting with a BMPCC for a little over a year now and feel a liberated with not having to process and heavily color grade cinema DNGraw. I am pleased with the results with the VisionColor picture profile over CineStyle.
Basically....buy what you can afford. If that means a 7DII and a good lens...then do it (and the 7DII finally has a headphone jack). The other posts here suggest good cameras as well. Good luck.
Kendy Ty uses a Canon T2i (no MLraw hack) and a Sigma 30mm f/1.4 lens for all of his films.
This looks like it goes along with their test footage they released in 2013.
According to a Google Shopping search, it will cost $1,199 at B&H.
