Very expensive as well but will give you a new set of lenzes :) I wish he had filmed some more real life stuff instead of the toys, those images don't say much.

Re: Metabones Speed Booster for NEX E Mount

I plan on ordering the Metabones adapter this week. But not this one. According to Metabones neither one of them AF very well at all. I am getting one out of necessity to use my Canon glass.

This thing makes some pretty outrageous claims. It would have to be explained to me how adding another glass element between my lens and sensor is going to make it "sharper and faster".

Re: Metabones Speed Booster for NEX E Mount

Well, if it lives up to it's claims I"m getting one, not immediately since my bank account is still recuperating from buying the Sony but in a few months yes, just the fact that you can get a total different focal length with the same pair of prime lenses and a stop of extra light sensitivity is unique. I already have a simple non electronic simple adapter that utilizes the cropfactor and then the speed booster could give me 3 new focal lengths for my 3 primes.

Just have to wait and see until more user experiences appear.

Re: Metabones Speed Booster for NEX E Mount

It did throw me for a loop. Here I am about to order the normal one today and now they have this one.....

I don't care a lot about the focal length change because my Canons will have a huge range covered with the standard adapter. So that leaves their claim for sharper and faster.

My glass is all Canon "L" series. That is damn near as sharp as you can get. How is adding another third party's piece of glass going to make my lenses sharper?

Faster, now that interests me. But I can't wrap my head around how it works.

For the extra 200 bones I think I will go standard for now. A DVINFO user will have to tell me they really gained a full stop on every lens.

Re: Metabones Speed Booster for NEX E Mount

Made my decision and ordered the standard adapter today. Even if the MAGICAL speed booster tuns out to be the real deal I can always order it later. For now I need to get my Canon lenses back in the line of duty.

Call me a cynic, but making my good glass sharper and one stop brighter seems like, "to good to be true to me" and that means it probably isn't true. I will be glad to eat my words if I'm wrong. Time will tell.

Re: Metabones Speed Booster for NEX E Mount

I think metabones is a company that cannot afford to trow out false claims as they have a very good reputation for building quality stuff, but I must say I"m asking myself why no-one has ever came up with the idea to build such a device before? It does eliminate the cropfactor AND makes the lens a stop faster, that sounds revolutionary to me. If it would also eliminate the moire and aliasing I would drive over to metabones to get one now :)

It is old tech - not new Klingon tech - it will shake the market....
First approaches from 1928 are not so good but the new Mirrorless Design allows it to push it to High End State of the Art Level.
Two Optical Cracks gurus Brian Caldwell and Willfried Bittner are the Designer

and here other facts FS700 Speed Booster adapter:


24mm T1.5/36mm crop1.5 = full frame 24 T1.1
35mm T1.5/52.5mm crop1.5 = full frame 35 T1.1
50mm T1.5/75mm crop1.5 = full frame 50 T1.1
85mm T1.5/127.5mm crop1.5 = full frame 85 T1.1


FS700 crop 1.5 MB EF-->E adapter


24mm = 36mm
35mm = 52.5mm
50mm = 75mm
85mm = 127.5mm

You'll gain a T-stop, not an f/stop, but yes the image should be brighter.

Re: Metabones Speed Booster for NEX E Mount

Straight from the bosses mouth guys.

Hey Chris, you probably don't remember me being around but I was really active here back when this place was the XL Watchdog. I went on hiatus for several years and recently returned. Congratulations on turning this into the most informative site on the web for us video pros!!!

Re: Metabones Speed Booster for NEX E Mount

Hey Chris,

I came to research a new camera purchase and got caught up in all of the great information and community here. I'm hooked again!

By the way, because of the research I did here for that purchase I had to go over to the dark side and buy a Sony after fifteen years of being a Canon guy! Who says old dogs can't change.

Re: Metabones Speed Booster for NEX E Mount

I've used them with other Cine lenses, but not the Rokinon one. Just make sure the flange distance works.

The most obvious thing you lose, because there is no lens control means there is no aperture control, no IS, no AF. (not that AF is very usable with EF glass anyway).
