The Pocket 6K is a 1.63× Super 35 body on the Canon EF mount — which means the whole EF lens universe plus almost any vintage glass on a cheap adapter. Less crop than the 4K, so your lenses stay closer to their marked focal. Here's the kit that actually earns its place, and how each lens frames on the 6K sensor.
Sigma 18-35mm f/1.8 Art
The definitive Super 35 lens. Covers the sensor perfectly, f/1.8 throughout, and 18-35mm (~29–57mm full-frame equiv here) is the range you'll live on. If you buy one lens, buy this.
Tokina AT-X 11-16mm f/2.8
When 18mm isn't wide enough — interiors, gimbal, establishing shots. On the 6K's Super 35, 11-16mm gives a true wide (~18–26mm equiv) that the Sigma can't reach.
Rokinon / Samyang Cine Primes
De-clicked, geared, matched cine primes (14/24/35/50/85mm) for a fraction of real cine glass. Manual, consistent, and they look far pricier than they are. Perfect first prime set.
On the 1.63× Super 35 sensor, every lens frames a little tighter than its number. Tap a focal to open that build in the simulator.
EF adapts almost anything. A $20 ring puts a Contax Zeiss Planar or Helios on the 6K for a look no modern lens gives — and on Super 35 those full-frame primes have plenty of coverage to spare.

The Sigma 18-35mm f/1.8 Art. It's fast, sharp, covers Super 35 exactly, and its range covers most of what you'll shoot. Add the Tokina 11-16 when you need wider.
Does the 6K need a speed booster?
Not really — at 1.63× crop, EF glass already frames reasonably wide. That's the 6K's advantage over the 2.02× 4K. A reducer is optional, to push a full-frame lens toward full-frame field of view.
Will full-frame lenses work?
Yes — full-frame EF lenses more than cover the Super 35 sensor. You're only ever using the center, which is usually the sharpest part of the glass.
