The Rectimascop 48/2x Anamorphic Lens arrived in the mail today.
I'm still waiting for the clamp to properly connect it to the GH4 lens, but I couldn't wait to try it out, so I did some test shots in my living room, connecting the Rectimascop to a Helios 44/2 lens using a reverse macro ring.
It's not properly aligned, as you can see from the flares, but I love the character and the new artistic possibilities opened by the new 4K photo mode with its new aspect ratios (1:1, 3:2, 4:3).
I'm also waiting for a diopter from Ebay to shoot closer objects.

Music by me.
Edited with FCPX.
All flares were done in camera. :)
