“It has full automatic aperture control” – No, it doesn’t. Nor does it claim to. It has the same manual aperture control as any other adapter out there.
Seems to have its own iris dial in the adapter so it does.
Independent on any lens aperture contol..
Still, the aperture is not “fully automatic”, as the text above says.
It’s not any kind of automatic.
what is going on with this site?!
What admin probably meant was, it has its own independent aperture control instead of relying on the one on the lens/camera. The Nikon G Speedbooster has a built-in aperture dial, but I’m not sure if their Canon FD one does? Anyone know?
Why are EF versions of all these speedboosters so rare? Who the heck still uses FD lenses?
Most anything can be adapted to EF, so if they release a speedbooster for that mount there’s no reason to release any, for any other mounts. Money grab. Least that’s my theory.
It’s bc EF lenses are controlled by an electronic iris which means it has to work with the electronics of the lens and camera it’s adapting to so you can control aperture – which would then be done via the camera like on a Canon. That takes time and requires dif electronics for each system.
Exactly. All my speebosters are EOS, since almost anything can be attached to it. The same reason all my manual lenses are Nikon mount.
They do have an EOS version but it’s priced way higher than the rest for the reason mentioned below. One Speedbooster to rule them all.
FD lenses are numerous and cheap – precisely because almost nobody uses them (yet, but with mirrorless, they are useful again). If I wanted to spend a lot of money, I would buy native 42.5/1.2, 75/1.8 etc, not longer EF lenses with a 1-stop speedbooster (but 2-stop speedbooster would be very interesting).
Has anyone done a good comparison of all the wideconverters?

Holy sh!t, with just the thumbnail you can tell the knock-offs are all useless. Getting the original FoV and additional light gathering is great, but no enough to justify ruining the lens’s performance and character completely. IMHO this means it’s Metabones or none at all for me, unless of course Fotodiox turns out to be another optical marvel but doubt it.
That’s weird, the corners of the speedbooster look better than the ‘right side’ and ‘left side’.
But indeed it looks like the only usable option. So far.
In real world use the differences are not as dramatic as that post makes it out to be. Some of the cheaper adapters are downright terrible and others are pretty ok. Having said that, I own a Metabones FD Speedbooster. It did not make sense to me to put anything other than the highest quality glass available behind my Canon FD L lenses.
Why in the world did they make the Canon FD adapter with its own aperture control? All FD lenses have that built in. An artificial iris that far back is bound to cause image quality issues.
I own a LensTurbo adapter (for Minolta SR to Sony E-Mount), which is supposed to be second best and the only acceptable alternative to Metabones, but it is already so awful that I would not consider anything but Metabones in the future. I might want to wait for test results including the version II LensTurbo, though, which is supposed to be better than the earlier one.
There’s no artificial iris in adapters with aperture control, it’s just a ring that drives the mechanical aperture pin of the lens. Maybe the F-stop ring on the FD lens does not work when attached to the adapter, for whatever mechanical reason.
Thanks!
Probably because of this post: I had a dream last night that Leica came out with a new R3 and MR-Telyt-R 500/8, about $2000-3000 each. A Leica rep came to my house so I could demo them. The R3 was silky smooth, had lovely handling, had virtually no noise and no mirror black-out. They tried to make it convertible to digital, but could not for reasons the rep could not remember. But, then, there was a drop of silicone on the front lens of the MR-Telyt, and the surface kept bubbling up in a gooey mess, and I kept trying to pull it off, which completely ruined it. I tried to argue it was a manufacturing defect, and I didn’t want a film camera anyway, and maybe Kodak lens cleaner could take it off, and then I woke up.
They are all crap. Do you need a hyperlink?
Sure, if it is a well-done comparison of crap.
I hope it dos not “feature the blue spot issue” in the center.
How about a speed booster adaptor for MD Rokkor to M4/3
Here it is. It will be one of the first accessories I’ll be buying when I make my switch from FT to MFT, and then my Sony NEX-C3, which I’ve been using with my Minolta SR/MC/MD lenses, might likely become retired. By the way, I probably won’t bother with anything but the original Metabones adapter, after having tried a “LensTurbo” (Mitakon) adapter on the NEX, which is awful (I don’t know how much better their version II of the adapter is, though).
can´t find any reviews
I wonder why…
just came out… so no reviews yet.
Where is the sarcasm police when you need them…
zzzzzzzzzzzzzzzzzzzzzzzzz
Yeah, sarcasm easily gets lost in text, however I did get your were being sarcastic. I was replying to “matt” but seem to have replied to you.
Here’s my question… if I got it right, the same adapter for nikon g lenses will work on my BMPCC and on my GH4? I thought there should be a slight difference between these because of the sensor distance from the mount.
Could you please confirm?
Many thanks
Franck
If you can use M43 lenses on your BMPCC then you should also be able to use this adapter on both cameras.
The fact is that at metabones they have a different speedbooster adapter for m4/3 and for BMPCC… that’s why I was wondering if the adapter wouldn’t be to close to the sensor…. as they say…
They did something with that BMPCC speedbooster to make it incompatible with the GH4. I don’t know why, because the only issue it would otherwise have on m43 sized sensor would be the vignetting. But regular m43 speedboosters (0.72 factor) can surely be used on the BMPCC, same sensor distance, or you wouldn’t be able to focus any m43 lens on the BMPCC.
The BMPCC version achieves its wider crop with a different optical design that extends further into the camera body. While the flange distance of the BMPCC and a GH4 are the same, the GH4 (and most other MFT cameras) has a mechanical shutter in front of the sensor that will hit the BMPCC speedbooster. The speedbooster should mount tightly, but even doing just that could damage the camera and/or adapter.
The reason the BMPCC one won’t work on the GH4 is that the lens sticks out the back of it too far to clear the mechanical shutter on the GH4. If you try to use it on the GH4, you could damage the shutter. The sensor distance is the same, but the GH4 has a shutter in front of it.
Thanks, very important info for owners of the bmpcc version and gh4 and bmpcc.
yeah ! many thanks for the informations
It will but the crop factors will still be different between the two, as the video mentions, because the crop factors between the BMPCC and m43 are not the same.
“It has full automatic aperture control”
For Canon FD? Are you sure? I bet it does not even have m43 electronic interface, yet alone automatic aperture control.
Doesn’t look very good here…
http://www.personal-view.com/talks/discussion/7356/fotodiox-excell-lens-turbo-analogs-for-m43-and-nex/p14
Not very clear if it’s really this excell+1 they tested.
no electronics – no auto focus 🙁
Fotodiox fails again. Every test hitting the web right now has proved that this adapter is an optical mess for any M43 camera with a sensor larger than a BMPCC. Blurry, inconsistent images, unusable wide open, and is an utter waste of money and time. The BMPCC may have a sensor small enough to avoid the edges of the lens adapter and most of the optical issues but even in the middle it has proven to be no NEARLY as sharp as the Metabones Speedbooster.
This is a “3 strikes your out” scenario for me with Fotodiox… Again, they tricked customers into thinking this “Excell+1” is a “new” product and that it’s been “beta tested”, which it is completely and utterly false. There is no way anyone who knows how to use a camera actually tested these out.
Bohus puts his name and reputation out there as the face of Fotodiox, and if I was him, I’d be completely ashamed of myself and of Fotodiox right now. This is the exact same scenario for many a while back when the previous adapter turned out to be unusable as well… Instead of getting rid of bad product, they are trying to cleverly re-sell the adapter as a “stylistic lens: Light Canon”… Do they really think that the indie filmmaking and photography market is that stupid? I think not.
Skip out on this Fotodiox debacle, save yourself a bunch of hassle, pony up the dough for the Metabones Speedbooster, and leave Fotodiox to their shame.
