SAR reader Alan got a confirmation from metabones that they will start to sell an A-mount Speed Booster adapter for NEX cameras in August! That’s great news! All current Speed Booster for NEX can be found at Adorama (Click here).
And in the meantime a third company is now offering a “Speed Booster” alike adapter. Fotodiox launched the Vizelex Cannon Nikon G to E-mount adapter which is in Stock at Amazon US (Click here). But from first testings at personal-view
we know that the quality is inferior compared to the (more expensive) Metabones.

Great news for STF owners!
Would some-one kindly explain what a Speed Booster does and how it works. All I can see is a macro extension tube and using one slows down the shutter speed.
Ignore that request. I’ve found the information and it sounds exciting.
It allows FF lenses to be used on APS-C cameras and boosts the speeds by one stop so that an f2.8 becomes f2 improving low light capabilities. Correct?
Yes! it will improve light and even quality of pic! and making apsc pic size becoming larger, likely full frame size i think? I get this news from metabones support team 100% sure!They say may launch it at August! So for me it would be want better quality or extra light benefit = use metabones, want fast auto focus use sony adapter.
Can you please change the title? Based on that, I was expecting a speed booster for A-mount cameras, not A-mount lenses for E-mount cameras. Very annoying. Thank you.
LOL, same here!
ADMIN – please?
done!
So I will be able to use my dear old Minoltas 100/2, 35/2, 24/8, the way they’re supposed to be used? Great news! I’ll gladly sell my LEA2 (although that’s a nice piece of equipment)!
Yes! You will also get more field curvature, flare, peripheral blur, more aberrations and lose autofocus — all for free!
Not so bad as you describe … -> http://www.samdcruzphotography.com/general/sony-nex-metabones-speedbooster-canon-50mm-f1-4-becomes-f1-0
And I want to make portraits with my 1.4 85mm so I don’t need a snappy af.
WOWSA! FOR FREE?? REALLY? WHERE DO THEY GIVE AWAY SPEED BOOSTERS FOR FREE??????? I WANT TO KNOW AND SAVE OVER 400 DOLLARS!
He means you get all the problems for free as a bonus when you buy the adapter.
That are really important & good news! I’ve been waiting a long time for that! So the new NEX has to come!
I’m sure it works just as fine on your present Nex.
Still waiting on that FD mount version…
Oooooh, or imagine a Contax G one… Metabones already makes one of them! C’mon guys!
What about the promised Canon FD-mount Speed Booster? I’m tired of guessing and waiting…
You can try the Lens Turbo adapter – it’s not bad, either.
Some thoughts and samples taken with different lenses are available on my blog: http://per-analogia.blogspot.com/
I second that, the lens turbo is quite a good performer optically. The price is another appealing point.
You can see some photo samples on my site using Nikon lenses.

A good thing for a mount users.
Still would ha e to sacrifice image stabilization.
I would like to see stabilizatiom in the sensor.
This can be put behind the sensor making the camera just a little thicker.
As of now nex has the appeal if being fully functional for any manufacturers lens that has stabilization. Add built in stabilzarion and it becomes more of a universal camera. Thats worth yhe extra thickness and it would add to sonys potential customer base.
Great feature for FF NEX, BTW, as being an adapt-all camera!
If sony does make a ff nex this would definitly be a smart place to include stabilization.

I want A-Full Frame to A-ASP-C Mount !!
A-Full Frame -> Metabone -> A-ASP-C -> LA-EA2 -> E.
Metabone will got perfect auto focus !!
I understand why when using third party lenses like Minolta, Nikon, etc that the auto-focus will not work on Nex camera. However it not clear to me why a speed booster that adapts between Alpha lenses and the soon to be released Nex-7 replacement with focusing built into the imaging array would not be made to auto-focus on Alpha lenses.
It is likely the speedbooster will have the characteristics of the la-ea1, which means possible slow (SLOW) AF for certain lenses. I dont see how they can add in a translucent mirror to have good af on all lenses…
With the focus mechanism on the imaging array in the upcoming Nex-7 replacement there is no longer a need for a translucent mirror anywhere. A servo loop will be completed when mechanical corrections are provided to the lens. The motor could be in camera and coupled to the lens, within the adapter, or with SSM lenses within the lens. Anyway that’s the why I envision it working. I ope I’m right, but it could be a pipe dream.
I bought that POS viselex. the usable image area was not much and the edges looked like motion blur. Maybe it works with a digital lens better but with my Nikon 28-70 F2.8 ED and a 135mm F2.8 nikor it was HORRIBLE.
I think the sitemaster veered into extreme understatement when he said “we know that the quality is inferior compared to the (more expensive) Metabones”.
Going through that personal-view.com thread shows that near the end, it was almost torches and pitchforks… until Fotodiox stepped-in and offered refunds or the option for free replacement with their MkII version that’s being promised in 3-4 months.
Based on this video, I think I’ve seen Coke bottles with better optics…

Is the Lens Turbo just as good as the Metabones? I have seen some negative reviews (green dot in the center from bright subject, etc.) of the Lens Turbo linked from this site.
Does the Speed Booster worth the extra cost?
It’s different.
The corners seem to be softer with Lens Turbo but the barrel distortion is stronger with Speed Booster.
The center sharpness is comparable.
A blue/magenta dot occurs in the center while usiong the Lens Turbo but only when shooting against the light and with the lens stopped down.
The Metabones adapter supports AF with some Canon lenses and supports aperture change.
But it’s really difficult to compare the two adapters since they don’t come in the same mount version and the results are dependent on the lens attached…
EDIT: now they both come with Nikon mount, so a direct comparison may be possible.
Greetings,
I hope to see LA-EA1 replacement adapter (rather than A-mount speed booster), which would treat aperture physiology differently than along with Sony philosophy. I believe that Sony should be boiled into a hell for this automatic aperture feature in a-mount adapters. Metabones EF-nex adapter’s preselected aperture it’s a lot of better idea 🙂
Best regards, WZ.
No mention of a Metabones Speed booster A-mount to NEX on Metabones’s Web site. Is this a rumour or reality?
sto aspettando con ansia che metabones faccia la versione per obbiettivi
Alpha/Minolta .
mi potete tenere al corrente quando uscirà ?
grazie.
