After reading this thread, here are my suggestions based on experience with lenses and the Pocket 6K, and other commentaries.

Canon 17-55mm f2.8 IS
Tamron 24-70mm f2.8 VC

And I will be getting a lens with built in IS. I'm still asking here for any recommendations about a lens if anyone can please help.
The Canon, Sigma, and even Tamron still photography zoom lenses mentioned above are all nice lenses and provide some visible stabilization to not so steady hands. I owned them and on a BM Pocket 6K camera, do not assume you will get a stable shoot in a RnG situation, particularly if you are having some movements, even little ones. It doesn't cancel out the shakes at all. The lenses are sharp but not as quite sharp as the Sigma ART 18-35mm. Focus is average but not much of a throw. Overall, they are good walk-about lenses - no cinematic qualities but this has more to do with the cinematographer than the equipment.

Gigabyte for Gigabyte, SD Cards are cheaper than CFast cards. I don't know where I can find a 256Gb fast SD cards that is cheaper than a 256Gb CFast card. However, CFast cards have been going down in prices that you can expect to pay between USD$0.97 to USD$1 per gig on CFast these days. That's fairly good pricing. CFast are, well fast - especially those with fast write speed. Angelbird is also my recommendation.

I don't own the DZOFilm glasses but I rented and used them on my Pocket 6K and UMP G2. Like Tim said, it is a nice combo and I like the images the produce. I have them on my wish list. They're not heavy and some weight is a good thing - better focus and stable shots.
I still think the Sigma ART 18-35mm is the best all around lens for any Blackmagic cameras. It does not have stabilization but what feature and quality it gives easily takes care for what it lacks.
