I purchased the Metabones Canon EF/ Micro 4/3 Speed Booster XL-BL from B&H Photo in April of 2016. My application was using the Panasonic GH-4 and the Speed Booster with the many Canon lenses I had accumulated. The unit worked well most of the time, but the GH-4 would occasionally show the “Lens attachment failed” error screen when I attached a different lens. I thought it was the lens choice, but noticed that all but one of the lenses I had were original Canon units. On 09/29/2016 the GH-4 firmware was updated to version V25 and the Speed Booster interface problem began to occur much more frequently. I continued to think it may have been due to my inexperience with the GH-4 camera functions, so I tried to learn about and attempt almost every combination of camera and lens settings. Nothing worked. On 12/07/2016 the Speed Booster firmware was updated to version V2.5, and on 12/08/2016 the GH-4 firmware was again updated to version V26. Now EVERY lens I try to attach gives the same attachment failure error message. I can only use the combination if I place the lens inside the Speed Booster mount but only turn enough to secure it without actually connecting the contacts of the lens and the Speed Booster. Of course this won’t allow any lens communication with the camera, but will still allow the use of the lens as a completely manual unit. I have tried both the Green Power-Save mode (default) and the Advanced Manual Focus mode on the Speed Booster and I still get the same results. I find it almost unbearable that I purchased this unit mainly for the ability to use my Canon lenses on the GH-4 like I use them on my Canon bodies, i.e. with full control of the lens focus functions. I can’t believe a $650 unit designed to do this, heralded as the best unit of its type available in the marketplace, only lasted for a few months before failing completely. Of course I am beyond the 30 day period usually given for a return window. I could never give this unit more than one star, and would seriously love to give it much less than one star, if that were possible. I have never been as disappointed with a seemingly serious photography product as I have been with this Metabones unit.

UPDATE: I have been corresponding with B&H Photo continuously during this ordeal and have understood their position regarding the return window. However, as of this week they have agreed to replace the unit with a functioning one as soon as they receive my failed unit. I will update when the replacement unit arrives and the functionality is verified.

FINAL UPDATE: I received the replacement Metabones Speed Booster from B&H Photo today as promised. Of course I was anxious to mount the adapter on my GH4 camera body and start the testing, and that’s exactly what I did. The adapter was initially mounted on the camera body and the camera was turned on. The first lens I mounted was the EF 17-40mm f/4L and immediately the mount worked. The GH4 accepted the lens and was fast and accurate in processing focus info from lens to camera to lens. The Speed Booster and lens combo also resulted in an apparent 1.5 stop increase in the lens aperture, allowing me to shoot 4K video inside my home office under relatively low light (1 small lamp) at 1600 ISO and get excellent perfectly usable footage. Next I mounted the EF 70-200mm f/2.8L mainly to test the autofocus accuracy and the GH4 / EF lens response speed. The combination worked flawlessly with fast accurate focusing even in that low-light situation. I dare say even new Lumix lenses equipped with internal memory of bokeh files to use with the GH4’s new DFD focusing technology would, at best, produce only minimal increase in this focusing speed. This is, of course, what makes all the hassle I went through worth it.

Hey Tony. I have a GH4 with the same Speedbooster but I don't have Lumix lenses with the natural crop of the micro 4/3rds. I'm curious after having the Speedbooster for a while now what your impressions between the two and do you use both the Lumix and Canon lenses equally or are you using the Canon lenses more now that you have the Metabones? Wondering if the autofocus is worth investing in the Lumix lenses.

Hi tonytypes It's not precised on the metabones official website that all canon EF lenses work with this speed booster. They've tested on a few lenses only. Do u know if it works with all canon EF lenses?

Since the Canon lenses work on the GH4 now does that mean the Okii Follow Focus will work with the GH4? Not being able to control focus on the fly is the biggest issue I have with using a gimball.

No the Okii won't work with the GH4. It only works with Canon cameras. The only way to get follow focus control is to use an external motorized follow focus systems. And they cost money!

Please help!!!! Why does my aperture change to 0.0 when I plug it in?? I'm using a sigma 18-35 with the speed booster .71x ultra and a Panasonic g7. Everything else works fine, but i'm not sure what happened to the aperture!

Not a lot of lenses on MIcro Four thirds? what more do you want? You have quantity and quality between Panasonic and Olympus lenses.... When you think on buying a camera, that is part of the equation you need to put on the table, you want a new brand and system you have to buy a new set of lenses, or, you can stick with your brand or system of choice and keep the old lenses... Nevertheless, being able to adapt old lenses in new cameras and systems is cool, but, keep in mind that you wont take the most out of it, and a micro four thirds is about size and weight savings, if you buy a micro four thirds camera, and than start to adapt lenses from DSLR or full frame.... why did you buy a micro four thirds in the first place? But, good video, its good to know that there is brands creating choices for everyone.

I don't see why it would not work. If it's an EF mount lens it should work just fine. I know if you use that lens on a full frame you get the black circle when at 18mm. Shouldn't have that issue with the GH4 and speed booster I think

Shahid Hasan I've got a similar question with regard to a Sigma 35m lens (1:1.4). I'm pretty unfamiliar with lenses so perhaps all of the responses to the OP's comment answered my question. Can anyone clarify this for me? It'd be much appreciated!
