Can you share some pics of the process or result? Could you reattach the shroud? thanksNo, remove 6 screws on back of lens (4 on metal, 2 holding electronic contacts). Then the plastic shroud just snaps off (clips holding it in place). I can post pix if necessary.
The downside is that about half of my Contax Zeiss lenses don't fit on the speedbooster. Looks like something is protruding out of the back and preventing it from attaching.
As a side note, all of my Contax lenses work well with my C/Y mount Speed Booster.
Too bad they didn't make this newly released EF mount SpeedBooster Ultra.
The Speed Booster arrived this morning, a day before it was scheduled by FedEx.
Fit's great, & initial impressions are good, but noticed one odd behavior. Haven't tried all my EF lenses yet but when mounting the 24-70/2.8 & 24-105/4 the GH4's display shows the maximum aperture as 1-stop faster, however the 24/1.4, 50/1.2, & 85/1.2 aperture readout does not show the same improvement.
Eric also reported that his 24-105 jumps from f2.8 to 16. I tested out my 24-105 and couldn't duplicate the same. I tested out 85L, 24-105, 24-70mk ii, 70-200mk ii and they're all work properly.
It doesn't jump from but starts at 2.8. The IS does do some funky hard shake if I scroll to fast through the iris settingsEric also reported that his 24-105 jumps from f2.8 to 16.

How long did it take you U.S. guys to receive the adapter once you placed the order from Metabones?
