New Fotodiox Excell +1 Speedbooster Gets You an Extra Stop of Light on the Cheap

While not the first company to enter the speedbooster game, Fotodiox is turning some heads and dropping some jaws with their newly-released Fotodiox Excell +1 speedbooster.

Designed in two models — a Nikon F version and a Canon FD glass version — the Excell +1 lets you slap your ‘old’ glass on your MFT body and gives you an extra stop of light for about a third of the price of the competition.

Priced at only $160, the Excell +1 sets you back a whole lot less than the popular Metabones alternatives, which range from $400–600. And what’s more, for the next 4 days, you’ll be able to pick up the Excell +1 for only $140 if you buy it from Fotodiox themselves.

At less than half the price of the other options out there, the one obvious question on everyone’s mind has to do with the quality. If the world of speedboosters follows the age-old wisdom that “you get what you pay for,” the extra cash might be worth it.

Then again, look at the heated competition between Sigma’s 50mm f/1.4 ART lens and ZEISS 55mm f/1.4 OTUS… great things can definitely come in more affordable packages.

As for how various lenses will stack up and convert with the Excell +1, Fotodiox has provided the chart below for you to use as a little cheat-sheet.

If you’re interested in finding out more about or getting your hands on one of these new Fotodiox Excell +1 adapters, you can find them in both Nikon and Canon mounts over on B&H Photo.

    Why doesn’t anyone make an EF to EF mount? I wouldn’t turn down a bit more light.

  • jon

    Because of the focal flange distance.

    Hmmm- Interesting.

    2 questions come to mind:

    1) They show many more mounts on the chart (like Fuji-X, etc.) – can we assume that these are on their future roadmap

    2) Does anyone know if this affects DoF (shallower, perhaps?)

  • Heath Collins

    #facepalm Darn it; I knew that. I should have thought before posting. Thanks.

  • Mike

    I’ll make you an EF to EF mount, for free! just gotta find my trusty hammer.

    Double the f-number of the micro 4/3 camera to get the equivalent depth of field. The ratio of light is the same, but the depth of field is doubled. So if you’re shooting a 25mm lens at f/2, you’re letting in f/2 of light but getting a depth of field equivalent to f/4 (at a 50mm equivalent focal length).

    With one of these adapters, the f/2 lens becomes f/1.4. Then your equivalent depth of field is f/2.8, with a 35mm equivalent field of view.

    You could make and EF to EOS-M mount, which would actually be fairly interesting.

    I’ll start off saying I own a couple GH4′s with a set of Metabones Speedboosters. I love the Speedboosers, am very satisfied with them, and use all Nikon lenses on my GH4′s to get shallower DOF and better low light from the M4/3 sensor. I purchased one of these as soon as they were released, and created a video on it. (unboxing with a physical comparison to the MB SB) and some sample footage. The Lens is having issues when using fast lenses. I have sample footage in my first video as well. If you would like to see that do a YouTube search for: ” Fotodiox Excell+1 Unboxing Samples Overview & Metabones Comparison Speedbooster ”

    This is the first video I made on it, I will have another one soon with a direct image comparison and an update on the image issue along with sharpness comparisons. The build quality of this lens is fairly solid, and it mounts well to the camera and lens. The glass element has a blue hue to it that I show in the video, the Metabones doesn’t have this. The aperture control is has a very short throw and is really easy to adjust (maybe too easy) compared to the MB that has about 4x longer throw and more friction when adjusting. I will do more testing, as of now I would not recommend this adapter.

    Fotodiox fails again. Every test hitting the web right now has proved that this adapter is an optical mess. Blurry, inconsistent images, unusable wide open, and is an utter waste of money and time.

    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.

    When did James Spader start making camera accessories?

  • bohus

    I am seriously never going to shake this James Spader thing… I used to get it even back when we both had hair.

  • Kareem

    I have a heavy Canon FD zoom lens. Is there anyway to mount this adapter to a tripod to avoid putting so much weight on the threading of my camera’s screw mount?

  • Rev

    You do look a LOT like James Spader… You even have his vocal sound… That’s a good problem to have IMHO!
