(on a completely unrelated note, why do links to EOSHD show up like that?)

"Not everybody" here is a fan of his blog ;)

does anybody know where to get the c/y to mft speedbooster in Germany or anywhere whithin Europe releatively cheap (< than 400€ if possible)?

thanks in advance

@htf Have it shipped directly from them. I did without any problem, but of course you'll need to pay taxes and custom fee (which a dealer would add plus his/her profit anyway).

@ntsan What GH4 version?

Just a head's up for people considering the Rokkor MD to mFT SpeedBooster: They list three lenses as incompatible without modification. None of my MD lenses work without modification! I've tried 5 different models not listed on their website, so that's at least 8 and I'd guess ALL MD lenses need modification.

Their tech support answer to my queery: "Cut 2mm off of the pin." Their answer to my comment that their advertising is false? "Please cut 2mm off pin." I really would like a non destructive method. I read the post from @fredfred27 about filing the side of the pin a bit. That sounds like a good option unless I could disassemble the rear mount and remove the pin in a way that it could be restored. Has anyone done that or know if it's possible?

Thanks!

@David_Smith I used a dremmel to file the pin flat on the inside until it clears the Speed booster lens holder. It is not difficult and it is fairly quick. I used paper towels to protect and isolate the glass on the lens. Use a cardboard with small hole so only the pin to be filed sticks out... Al

@ umla, @ aljimenez, Thank you both for your (different personal view) replies! I'll certainly ponder the different approaches.

@mrbill

Just a heads up. There are issues with this and BlackMagic Cinema camera. Metabones has said they are working on EF to bmcc microfourthirds version.

And I will gladly pay it. Look at the list: •Increase maximum aperture by 1 stop. •Makes lens 0.71x wider. •Build-in electronics to control lens aperture. •The lens aperture is set by the controls on the camera body. •Powered by camera body •High performance 32-bit processor and efficient switched-mode power supply.

I have the Nikon m43 version, it does so much for your lens, like having a new one. One of the best investments I ever made.

@HillTop1 - call me a Bonehead... Though I'm not buying one right away, you have to remember, this is more than an adapter. You have quality optical glass that increases field of view and light transmission, then on top of that does what no other lens adapter has been able to do yet - communicate between M4/3 and EF. I don't use AF anyways, so not having it won't be something that keeps me up at night. I'm certain there will be others hitting the market down the road from other manufacturers, but as we've seen, Metabones does stand above the rest (though the RJ Turbo I bought is pretty stinking awesome too).
