Want a Cheaper Version of the Speed Booster? Say Hello to the Excell+1 from Fotodiox Pro

One of the most sought-after tools in video production these days is the Metabones Speed Booster, a tool which absolutely lives up its claims of making your lenses faster and wider, thus eliminating the dreaded crop factor from small sensor cameras like the Panasonic GH4, while giving you an additional stop of light. One of the problems that most low-budget filmmakers have with the Speed Booster, however, is that it's not inexpensive by any stretch of the imagination. At $490 for the BMPCC Nikon version (and even more for the Canon EF adapter), you're shelling out half the price of the camera just for an adapter. Luckily, Fotodiox Pro has just released the Excell+1 Micro 4/3 adapter for Nikon and Canon FD lenses at just a fraction of that price.

First, here's the launch video from Fotodiox that introduces the Excell+1.

And here's the chart from the video that shows how the Excell+1 effects the focal length on different formats.

In spite of the incredible price, there are some drawbacks to the new Excell+1 adapter. First and foremost is the fact that you're limited to Micro 4/3 as your base format, while only having the ability to adapt Nikon or Canon FD lenses to your camera. For people who are heavily invested in Canon EF glass, or for people who are shooting on formats other than Micro 4/3, the Excell+1 is not for you -- that is, unless Fotodiox continues to release new versions of the adapter with new mounts and formats.

At this point, we have no idea as to whether or not the internal elements of the Excell+1 are of similar quality to the Metabones Speed Booster, and whether or not there's a difference in image quality between the two products. There are some other lower-priced Speed Booster-like products out there, though quality can vary pretty significantly. At first glance, this seems like an excellent product at an almost unbelievable price, but there's no way to know for sure until we see how the quality of the Excell+1 stands up to competing products.

While it's available from B&H for $160, the Excell+1 will run you only $140 direct from Fotodiox.

Does the Excell+1 speed adaptor work with other vintage lenses such as the Konica Hexanon, which I noticed is visibly similar to the Canon FD in your video? Also will it work with an electronic Lumix 14-140 kit lens?
Thanks.

The 14-140 is a micro 4/3 lens, so it would not mount to the adapter. These focal reducing adapters are to conform the optics of lenses that were designed for larger sensors to smaller sensor cameras. Also, this one in particular is mechanical and could not communicate with the controls of an electronic lens.

The correct answer here is: "friends do not let friends buy Canon!"

There is a HUGE advantage to using mirrorless systems, such as it allows you to use Focal Reducers such as this article is about! Though personally I would (and do) use a RJ Lens Turbo over this.

Sweet! Can't wait to see some tests with these. Hope they make a Minolta version!

As great as the metabones speed booster is, it has many issues. Sometimes the aperture is actually higher than what you've set it (you have to stop down and back up to fix), and the softening of every lens kills me as well. Been thinking a lot lately of going back to the regular metabones for my FS700 / Canon lenses

my point being.... (before accidentally publishing) Id be VERY hesitant to try anything more budget than the metabones version as its already pretty problematic.

I have a cheap Chinese knockoff and it is pin sharp on a GH4. There's no reason to believe this adapter could not be as well.

The new Lens Turbo II's are actually really damn good. I also prefer the way they lock to the camera body compared to the metabones, like a PL mount.

I had similar quirks on my EF speed booster for the FS700, as well as some soft corners. The Nikon speed booster for MFT on the other hand has been totally sharp. Also, as it is mechanical, it is perfectly reliable. A stepless aperture ring on every lens is a big bonus for me too.

Thanks Jay. I was just wondering about the Speedbooster for Nikon on MFT. I have a ton of Nikon lenses and am about to pick up a GH4

This is why people should only buy Nikon F mount lenses and never Canon EF!!

Is just quite simply the smart thing to do :-) To "future proof" your lens investment.

The official Metabones Speedboosters, when used on the appropriate camera's, actually make the image perceptibly sharper, so I don't know where you get the idea that they make them softer comes from. These knock-offs on the other hand...

If you're talking about revealing corner softness of a lens that was previous hidden from a crop, then that is another thing entirely.

The RJ Lens Turbo is fantastic (I use one) and even cheaper, you can buy it here and read its reviews:

Thanks for the info. Can't believe they did not come out with Excell +1 for Canon EOS Lenses. I read on Metabones website which lens work it theirs, and I own a version 1 of a lens thats on their list, But there's no indication if my lens will work. I have emailed them 3 times and yet no reply. I think I am going to go with a RedRock Micro Live. At least every time I have emailed them they got back with me.

Hi Miznul,

Sean here from Fotodiox. I filmed and edited the launch video. The aperture ring is de-clicked, so you can smoothly adjust the aperture during a shot.

Has there been any discussion of adapting M42 to M4/3? I have a pile of excellent M42 glass and I'm nervous about buying an ebay special to adapt them to a Panasonic GH series camera.

Do you have a rough time frame when it might be available for EOS lenses? I was very surprised it was not released the same time the Nikon adapter was released, with Canon EOS lenses being at least or more half the market.

I'm surprised it is not obvious to folks why Nikon F adapters get released way before Canon EF ones... is because Canon is a pain in the ass to work with if you're trying to design an adapter for them!

This is why I keep on repeating over and over..... people should buy Nikon F mount lenses, not Canon EF! This holds true almost no matter what brand camera you might be using (Canon/Nikon/Sony/Olympus/Panasonic/etc...).

You would think with all the Canon EOS glass out there, that adapter would have been a no brainer, and since Metabones just released theirs it would be a good time to release Ecell +1 for EOS lenses at a fraction of a price. Guess they thought more people want to use Canon FD lenses. I wondering if they are hiring for Product Development because the first thing I would have done was, hey why not make one for Canon EOS.

All those Fotodiox adapters I have purchased over Ebay have being such crap. Their fit is poor and sloppy, locks are of very bad design. Maybe these new ones are better...

With the T-Stop being the definite amount of light coming through the lens, what is there to profit from speedwise instead of a smaller DoF? if there's actually is, can anyone give a good explanation?

I am not 100% sure of your question, but I will try. These focal reducers DO NOT make the depth of field more shallow, it only changes the amount of light gathered by 1 stop. A 50mm lens has the same depth of field whether it is on a 5dIII, GH4, or BMPCC with a focal reducer. This allows you to get more light to your sensor without getting a shallower depth of field and allow more to be in focus. If you use a 50mm f1.8 on a 5dIII with an ISO of 800, you can use that same lens on an APS-C with a focal reducer and that will give you a 50mm f1.2. The depth of field is the same as on the 5dIII, but you get 1 more stop of light, so you need to either stop down the lens by 1 stop to get a deeper depth of field or lower the ISO by 1 stop to 400 and get a cleaner image.

The purpose of the speedbooster is to allow the likes of a "50mm" lens to be used on MFT while more or less preserving the same field of view as that of a 50mm lens on S35 - So now we have it both ways, we have the field of view AND the shallower depth of field of a 50MM. Without speedbooster we are forced to use a 24mm lens (for the same FOV), and we know what that means for depth of field.

Hi guys. I have a couple of questions about this adaptor:

1. Does it fit on a GH4?
2. And, does it allow me to use all my Canon EF lenses?
3. Does it allow auto-focus and auto-aperture when used?

Sorry if these question seem easy but I'm still confused as to what these adapters advantages and disadvantages!

Cheers!

Hi Saad,

Sean here from Fotodiox. I filmed and edited the launch video. The Excell +1 works well on the GH3 and GH4. We currently aren't offering an EF version of the adapter, and no, the adapter is entirely mechanical, so it has no electronic control over the lens.

It's hard to control electronic aperture of EF lenses. It has taken metabones forever. They only have FD for m43 right now too.

FD glass is considered comparable to old Nikon glass, only it is much cheaper. Canon screwed themselves by changing their mount to an EF mount whereas Nikon kept their mount pretty much the same, hence the reason why you can use old Nikon glass on almost any Nikon camera and only need a simple adapter to use Nikon glass on Canon EF mount cameras. Until now you could only use Canon FD glass with an expensive adapter that made your image 2 stops darker and doubled the focal length of your lens making it mostly useless for such light-sensitive sensors these days.(a 50mm f1.8 would essentially become a 100mm f3.6).

Focal reducers dont make the depth of field more shallower, it only changes the amount of light by a stop – 35mm lens has the same depth of field whether it is on a Red or the award winning GH4.
