ZF Lenses. EF or Nikon Speed Booster?

I have a set of 3 Zeiss ZF lenses (25mm, 50mm, and 85mm). I want to get a speed booster for them for my FS100.

I was looking at the Nikon one, but then read some reports that these manual (de-clicked) lenses also work on the EF speed booster.
Since I also have some EF lenses (I have a 6D), I was thinking about just getting the EF version.

Did anyone encounter issues with this approach? I don't mind the extra costs.

Any advice greatly appreciated!
Cheers
 
You'd need the EF-to-NEX speedbooster, plus a F-to-EF dumb adapter for each lens. You get one more interface surface between your glass and your sensor, which increases the chances that you'll have some tilt. Once you have ONE adapter, though, you're in that boat anyway (here). And I never cared, btw, since it shows in tests but not so much in actual pictures: all my lenses are for the Leica-R mount, adapted to whatever my current camera will use. If the Canon lens set is juicy, I'd go with the extra interface.
 
I do what Samuel does with my Zeiss ZF lenses: Nikon to Canon Adapter to Canon Speed Booster. Works perfect.

The Fotodiox Pro Nikon to Canon adapter works great with zero play. It's about $80 I believe. They're very hard to take off since they fit so tight, so I get one for each Zeiss lenses to save time.
 
That route will give you more options, but I'd have serious concerns about putting adapters on top of adapters (it's just more to go wrong). Plus those Fotodiox ones are a biatche to get off once you put them on.
 
* single speedbooster, nex to nikon: $430
* single speedbooster, nex to canon, plus three fotodiox pro canon-to-nikon adapters: $600+$210=$810
* two speedboosters, nex to nikon and nex to canon: $1030

if you had five ZF lenses instead of three, it would be a much simpler decision...
