Looking for a wider fisheye or an adapter for Raven

[Sam Fultz]

I've been using the canon 8-15mm fisheye for the Raven but I'm look for something wider. I'm wondering if anyone knows of a wider quality fisheye that could be used with the Raven?

I'm also wondering if anyone has used a metabones adapter with the Raven before? I'm thinking maybe I could use a Canon Ef mount-X adapter with X fisheye and therefore make it wider with help from the adapter?

Any info anyone knows is great, I would love to not have to rent gear to try it out.

Not cheap, but 250 degrees of bad-assery here: https://www.ducloslenses.com/products/entaniya-hal-250

The Entania website has awesome tech diagrams showing various FOV image circles vs image sensor size. They have a number of other fisheye designs if the 250 is too much for you.

Yep, I just used the 220 and was pleased. They are pricey, but if you need it, you need it!
