GH4 GH5 - Reco's on lenses? Also, which Voitlander for Anamorphot 1.33x

[chlywly]

Hey guys, so I'm used to shooting RED, before that I was using a 5DMKII/III with ML. I pre-ordered the GH5 and I'm excited to have some DSLR fun again. With that said I currently have a few Canon EF mount lenses, so i'll be getting a SpeedBooster Ultra.

What lenses would you recommend on the wide/mid range for this body? I'm looking for something vintage, stylized as well as clean, fast and modern.
Also, what are some indispensable accessories for GH5, obviously extra batteries. Hand grip? Which Flash is recommended.

Here's what I'm thinking of now >

Voitlander 17.5 or 25 | or SLR Magic 17.5 or 25 /w SLR Magic Anamorphot 1.33x adapter. VS THE SLR MAGIC Anamorphic 2:1 Cine Prime

Two others to consider:

I own a complete set of the Rokinon cine lenses. I appreciate the cine features, but understand that the image is just a bit "meh." Not particularly sharp or contrasty.
