Quick question. So I just received my metabones speedbooster Ultra XL (X.64) adapter for use with my BMPCC 4k and my Rokinon cine ds lens kit. My question is, with the 35mm, 24mm 14mm lenses I have the focus ring pulled all the way and I still cant seem to focus. I have the original bmpcc and speedbooster and I dont have a problem at all with those lenses. Am I doing something wrong or did I purchase the wrong speedbooster. Everywhere I read it said the MFT XL (X.71) was for apc-s lenses, which i dont have.
I assume you have the Rokinon Cine DS in EF mount. Is that correct? And I assume you have the SpeedBooster for BMPCC EF-MFT (0.58x) which worked well on the original Pocket.
Whether you have the XL or Ultra SpeedBooster, the lenses should focus.
Are the 14/24/35mm the only lenses you have or do you have other Rokinon Cine DS lenses that focus fine?
When you focus the lenses, does the front element extend or the rear element? I imagine it’s the front element so no issues there and that you are focusing manually.
Is there any chance that the new SpeedBooster is damaged?
Have you tried the old SpeedBooster for BMPCC on the BMPCC4K? It won’t display without a porthole, but inside the porthole, can you focus well?
