Personally I'm very wary of the Cinematics "rehouse" as it's more a sleeve job than rehouse.
If you're going for that lens, it would be worth considering GL Optics.
http://www.glcinemod.com/english.htmlI have one of their Tokina 11-16 T3 and very happy. I bought the lens new and sent it to Nan in China, and he did a great job. He's now selling them for nearly US$2000 less than when I had mine done nearly three years ago. At US$1585 it's a bargain.
I most recently had a Nikon DX 17-55 F/2.8 and Angenieux 28-70 f/2.6 rehoused by Kim Camera in Korea.
https://www.facebook.com/kimca1977/Kim did a great job - and each lens was US$2000 to rehouse. It's a true rehousing where he even reversed the direction of the Nikon lens!
My latest investment is a set of Mamiya Sekor-C 645 lenses (35/3.5, 45/2.8, 55/2.8, 70/2.8, 80.2.8, 80/1.9, 110.2.8, 150/2.8). I had a local lens tech de-click them for AU$40 each and because they have a longer focal flange than PL can be adapted to easily.
I ended up getting Krzysztof from c7adaptors (
https://c7adapters.com/en) in Poland to make a screw on PL mount (in the same way leitax mounts work) for each lens at US$200 each. He's done a beautiful job and now I have a set of medium format lenses I use with my UM4.6PL, or waiting for the day I may need to shoot on a huge sensor camera.
