Re: Canon EF-S lens on Panasonic micro 4/3

Hi, sorry for reviving an old thread but i can't find any info online about this topic and for some reason I can't create a new thread...

I have a Canon EF-S 18-55mm kit lens that came with my 700D. I recently purchased a Panasonic GH4 and Mitakon Lens Turbo focal reducer, from m43 to EOS... And I find that while the kit lens fits the adapter nicely, the manual focus on the EF-S doesn't work... it just turns endlessly. My Canon EF 50mm 1.8 works nicely with the Mitakon (manual focus included), and the manual/autofocus switch works on the kit lens when its on the 700D...

Is there an electrical connection that allows the manual focus to engage that is just not present when using a passive adapter (i.e the Mitakon as opposed to the Metabones Speedbooster)?
