Let's make a thread for sharing info on the Speed Booster, in terms of adapter/ lens compatibility, performance, etc.

I just got the adapter today (more like yesterday now), and haven't had the time to do any real tests (I received like 5 items in 2 days and am going bonkers now).

Very quick observations: it could be an issue with the cheap Chinese OM-EF adapter, but I couldn't get infinity on any of my three Zuiko OM lenses (28/2, 50/1.2). The 21/2 will NOT fit, as there is a protruding metal element that interferes (though shouldn't scratch the Speed Booster optics. relatively simple mod will be needed to mount it.

Zuiko OM 50/1.2 and 28/2 mounted fine, and performance seems to be as expected (i.e., good).

I'll try other mount adapters (including another OM-EF adapter that I have) and lens combinations, as well as comparison with 5Dmk2 in the coming days.

Thank you for this precious thread ; I'm a possible buyer if the S B is available in Europe (price => customs tax) AND if infinity is possible with stacked adapters (sound bad...)

Congrats! Do you still have some M42s to test? You already know my concern...hopefully it's just your OM adapter and you can get this fixed. Do the lenses feel like full framers again? Smile

OK, let's start posting some real info, shall we?

Thanks for the infinity adjust link Phenix; I indeed went and adjusted the infinity on the adapter. It got the OM lenses to get *much* closer to infinity but not quite, and after turning the elements about 15˚, I couldn't see a change any more, so there seems to be a limit to how much you can "adjust".

Next, I tried my two C/Y lenses, 35/1.4 Distagon and 85/1.4 Planar. SAME deal, not quite reaching infinity. I have two C/Y-EF adapters, too, so we're talking four different adapters.

I began to worry that it might be an issue with the Speed Booster, that I'd need to get a better calibrated copy. I mean FOUR adapters?

I only have two Canon EF lenses, the 17-40 F4L and TS-E 17/4L. They both, by default, go beyond infinity (one to deal with focus shift, the other because it's T/S), so they're not optimal to test the accuracy of the infinity calibration of the Speed Booster.

Well, I believe all FOUR of them came from the same Ebay vendor---and I don't want to name names; they work fine on my 5Dmk2 which is what they were designed for, but just as unbiased facts––BIG_IS. They make decent & cheap adapters.


I then tried: Cosina/Voigtländer Macro Apo-Lanthar 125/2.5 (EF mount) and I got infinity fine. I then tried Hartblei/Zeiss Super Rotator 80/2.8 (Nikon F mount with cheap Ebay F-EF adapter) and got infinity fine.. went over it, in fact, just a bit. I then tested that adapter with Nikkor 50/1.4; infinity fine. Then I tried Helios 40-2 w/ M42-EF adapter. Infinity probably spot on, but maaaayyyybe just a little shy. I then tried that adapter on Volna-9 50/2.8 macro--infinity fine. Same adapter on Carl Zeiss Ultron 50/1.8. Infinity fine.

Then I tried Hartblei Super Rotator 35/2.8 with EF mount; infinity fine. Sigma 8mm Fisheye; infinity fine (but AF doesn't seem to work?).

Finally, I tried Mamiya 80mm f1.9 (for Mamiya 645) with Mirex Tilt Shift adapter (Pentax K mount with cheap PK-EF adapter), and again infinity fine.

So, the gist is, the Speed Booster is fine, and I think all the lenses are OK, too (unlike what Metabones say about adapting older lenses); rather, it's the cheap OM-EF and C/Y-EF adapters.

Now I'm just wondering if I should just invest in the highest quality adapters (e.g., Rayqual) for OM-EF and C/Y-EF.

Here are some other observations besides infinity:

(1) Zuiko 21/2 will not fit due to rear protrusion in the lens itself; would require mod to lens, perhaps irreversible. 28/2 was fine; would LOVE to know about 24/2.
(2) My Carl Zeiss Jena Biotar 75mm f1.5 in Exakta mount with Exakta-EF adapter I got here, was a bit problematic... there was a bi of resistance as i tried to mount it and I didn't want to force it. It might have been the electronic contacts interfering with the after-market chip for relaying electronic information. Again, the chip works fine on my 5Dmk2, allowing e.g., for focus confirmation, etc. I'm guessing the Speed Booster is being built with a lot less tolerance than the 5D.
(3) Because the reducing factor of the Speed Booster isn't quite 1.5x (i.e., 0.67x), my Sigma 8mm fisheye is no longer a full circular fisheye: the top and bottom are chopped off a bit.


Besides the above three points, the Speed Booster pretty much acts like it's supposed to and I'm really satisfied. With some of the advanced features on the NEX6, I can foresee me needing less and less to use my 5D with my manual lenses Smile

Some lenses I tested




Some images:



C/Y Planar 85/1.4 + CY-EF adapter



C/Y Distagon 35/1.4 + CY-EF adapter


CV Macro Apo-Lanthar 125/2.5 (wide open, @ infinity): I'm pretty sure the vignetting isn't from the lens but maybe from a window sill?


Sigma 8mm F3.5 "Circular" Fisheye


Hartblei Carl Zeiss Super Rotator 80mm f2.8 + F-EF adapter


Zuiko OM 50/1.2 + OM-EF adapter



Mamiya Sekor 80mm F1.9N + Mirex TS adapter + PK-EF adapter

You should try shooting some test charts to see just what the speedbooster is doing. It looks like there is some light falloff on all the samples, mostly only very slight, but is this due to the lens being wide open or the speedbooster?

All the shots are wide open.

I'll print out a test chart and see what I can do. I also want to sit down and do comparison shots with 5Dmk2 mounting the same lenses.

Congrats on your new toy:P


Can you detect an increase in focus-breathing with it fitted?

I am interested also from shooting video where this can be important

You do mean, when compared with shooting with the same lens without the adapter? Or when compared with shooting on a full frame camera (like 5Dmk2)?

OK, will test for that too, though I gotta warn you, I don't have a straight up OM-NEX adapter (or even an EF-NEX adapter) so I'll have to use my EF-NEX Tilt adapter and try to make sure there's minimum tilt when I do the test.

Thank you for being our pioneer here.
Waiting for your next tests.
(yes, some corner vignetting)
