I was contemplating buying one of these for my old Nikon lenses that I use on my Lumix G9. This video convinced me. It's in the mail. Cheers.

Great video as always and it's awesome to see you back on KZfaq. Learned a ton.

The later generation Chinese adapters (i.e. Roxsen, Lens Turbo II) are pretty good too and quite a bit cheaper. I think I grabbed one for $80 delivered. Mine has performed well, with two caveats: 1) you have to be careful shooting into direct light sources...a blue hazy dot will show up near the center of the frame. 2) you might have to adjust the infinity focus on the adapter, which is very easy. The lens element in the adapter is held by a threaded ring and fixed with a set screw. I've looked at comparisons and the Metabones clearly sets the bar high. However, I've been really pleased with my Roxsen, which pretty much stays fixed to the back of my Canon FD 28mm/f2.0. For those who enjoy shooting full manual, these speed-boosters are a no-brainier.

I'm a very novice level photographer & cinematographer and your explanation is so easy to understand! Hoping to learn more from you

Amazing lighting and video quality. Nothing like I've seen here. You gave me good idea thank you.

Great video as always, thanks for sticking with the channel - I always look forward to your next upload !

Hey Ryan welcome back. You should definitely do a review on this 150$ Lens Turbos people are talking about. See, I live in Venezuela and I get to spend 300$ a year on gear bought in another country so i really have to be sure of what i'm getting. I would be cool and you'll make your viewers happy, not many vídeos about that online.

I concur huge fan of Metabone I have been a Canon pro for ages and have almost all L series glass. I just added GH5 to my video systems and when I mounted my 14 mm L II on GH5 with Metabone Ultra 0.64. Wow the focal length now is 1.7 and area of coverage is 24 mm. The results are simply amazing. The AF works great. I am amazed how well speed booster performs.

I just purchased a Lens Turbo II (EF to MFT) for my new UWA setup (rokinon 10mm 2.8). So far I think it's a pretty good adapter, built well (all metal), feels sturdy to me, and image seems sharp. The focal reduction is smaller (0.726) than the metabones one, and some reports say metabones is sharper, but for 150$ i take it as a reasonable trade-off. Again, images look quite sharp to me. I want to try and do a comparison to see if it sharpens the image (even slightly), will use my Helios 44-2 for that purpose. One thing I'm also trying to figure out, if you actually get larger out of focus area together with the increased light gathering capabilities. It's hard to see clearly, I tried doing side by side with oly 45mm, and bokeh seemed very close. I think LTII is a pretty good alternative overall. And getting a canon mount adapter (ef to mft) for either brand seems to make a lot of sense, I just bought a 5$ m42 to ef adapter ring and stacked it on the LTII to adapt my helios 44-2, and already ordered a PK to EF ring for my 44k-4 (also an interesting test I want to try, put those lenses side by side). It seems that canon is very easy to adapt to because of their flange distance (unlike nikon), so I should be able to adapt almost any legacy lens to my LTII, which increases the value imo.

Thank you for this review and info - you made it very easier to understand for someone looking to buy a micro four thirds camera. Thanks

thanks for the video! living in China, I am able to get all kinds of adaptors on the cheap. picked up an OM/M43 speed booster from Kipon today for the equivalent of just under 200 bucks vs the metabones at 400. built well, and good fun for sure! The 135/2.8 JC penny lens I bought to go with it make it like a 190 with the light gathering of F2! Pretty awesome.

Well it's about bloody time! Where you been dude? I've missed your MFT musings, hell, I've even missed your bloody cat! Welcome back. Atb, Daz.

I love adapting my old Pentax SLR lenses to my Olympus Pen E-PM1. I have purchased a few dumb adapters for my camera, and I have just recently ordered my own Focal Reducer (Which isn't a Metabones brand). With it I can attach my favourite Sigma 28mm f/2.8 and get a wider field of view. After carefully researching focal lengths of Micro 4/3s lenses. 28mm is roughly 56mm, and with my new Voigtlander 21/25mm Range Finder, it's referring to in Full Frame. In other words, 12mm lens for Micro 4/3s is about 24mm on a full frame.

Yay! Welcome back dude, I love your videos

I was really interested in this subject, thanks for sharing!

YAY youre back! I have both the Nikon G and Canon EF speedboosters and love them.

excellent video, I use the Zhongyi lens turbo ii with my Sony A6000 and its rarely off the camera now, It works particularly well with old Helios 44 lenses as it brings in the corner of the lens to the sensor giving the full frame bokeh swirl its famous for

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 that 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.

Thank you for the videos. I'm subscribing for more. I'd like to see reviews on different lenses for 4/3. There is a low of talk but i can hardly find any fair tests and comparisons

I use the Zhongyi on my Fuji..Love them....I've just bought one for the OMD-EM1....Can't wait to get it in...

So an E-M1 mk iii with a speedbooster could make a Olympus 12-100mm an 8.5-71mm lens, or in in full frame terms, a 17mm - 142mm f/2.8 lens? Would Image Stabilization continue to work on the 12-100mm??

Wlcome back! Fantastic video again! Please don't wait too long before you post another video:-) I've learned a lot of just watching your videos. You are very good explaining in a way that is easy to understand. Your videos are also alwasy very sharp and crispy! BTW: what is your preferred camera when you are travelling? Do you use a pocket sized camera or do you carry around a canera bag together with a lot of lenses. Personally I'm very happy with my Panasonic GM1 + the Olympus 25 mm 1,8 lens. Its light and easy to cary around and it also perform good in low light situations. Keep up the good work!

OK let’s say seven minutes into your video and I’m starving I really appreciate your video it’s really good idea but I was hoping to see more comparisons add a photo without the speed booster and a photo with the speed booster side-by-side so that I can make my decision but you know honestly I have to say wonderful BACKROUND ha ha ha ha but definitely a good video I appreciate your video thank you

Great video, I have been watching others review the speed booster on mft using Canon and Nikon lens. The combination seems to be awkward at best. Your choice of old Olympus OM lens looks like an excellent interface as the old OM lens to not appear to be larger than mft lens.

This is like the f/6.3 from f/10 focal reducer on a Celestron telescope. I saw a video where the guy said the sharpness was better basically I guess where it it is lowering the magnification of the image.

Unfortunately I have a Canon FD lens 28mm f2, an Olympus OM 50mm f1.8 and a Contax one 85mm and it would be impractical to get a metabone for each of them at that cost. I guess going for an native m4/3 could end being even cheaper. On the other end I like the feel of those old lenses better.

wow, I love your channel man! you're teaching me alot. I appreciate you!

is there a speedbooster for 4/3 to 4/3? would that make sense to out one in between my olympus omd and the lens made for it?

Another way to look at the speed booster, it projects a bigger image of the sensor into the lens

Will this work for Olympus 4/3 lenses?

Why the Speed Booster in your video is not the same model as the one on Amazon in your link...!

I ended up getting this for my GH4, but the control on the aperture control placement on the speed booster is a bit annoying.

So that version is now discontinued! I had to shell out an extra $50 for the new "ultra" version, but it looks like I will be getting one before just about anyone else as they haven't listed it on their site and B&H doesn't have it in stock yet. Fingers crossed.

would love to see a post processing tutorial from you.

alot of us shoot canon eos . . what can we do?? i suggested a product with these features to wotk with canob eos back in 2014-a lens is a lens-glass is glass . . is the hold up licensing?? . . do we still have to drive our "Geo metros/dodge neons etc"? . . cook on pit outside etc??

It would be nice to see one made for adapting the Olympus Pen-F (half-frame) lenses to Micro Four Thirds...but it doesn't look like there's anything (yet).

Is there one of these speed boosters I can use on a Cannon 5D II with 50mm lens?

it's been awhile welcome back👍👊

do they make speed boosters that just mitigate crop factor without having to go from one mounting system to MFT? looking at some native lenses and am curious if its possible to get like a .71x speedbooster that doesnt actually change the mount

Keep those videos coming! Great tutorials :)

Hey! Great video and some amazing shots. From what I remember you shoot with an Olympus Pen E-PL7, and from what I've read about Metabones Speed Boosters that's the only Olympus camera that's compatible with all kinds of them so that's great. I already have the EF to MFT 0.64x for my GH4, I love it. Now I'm tempted to get an EM5mkII as a second camera for my video work, but not sure if it'll work with the SB.

Sigma 18-35 with speedbooster on GH4 good for video .. Not for photo shoot ???

Very helpful ❣️

can't believe there is no real competition for this super expensive speed booster.

Im new to speedboosters. Could u tell me if it would work on my Nikon D5200 combined with a 35mm f1.8? its a crop sensored camera. I am a bit confused about the purchase.

Nice videos ,Good information! I'm stumped on lens choices I have the gh 5 And invested in the medanones speedbooster and the sigma 18-35mm because of all the great reviews I've read. The benefits I noticed are bettter in low light and lil more boki , but is that worth the $1400 for the setup? I also have the Panasonic 12-35 with dual IS this lens goes on my zyhriun crane matter of fact this set up is why I bought the camera. I'm now getting a zoom, I already bought the tamron 70-200 vc g2 but I hear so many good things about the Panasonic 35-100 dual ISSo I might buy that too to do a review on this exact setup. If I like the Panasonic 35-100 then I see no need for the medanones and the sigma and I could just buy a 1.4 prime lens for the Low light comparison. I guess my question is should I go nAtive or medanones? Is the 70-200 full frame lens with medanones much better then the native Panasonic 35-100 with dual Is? The tameron 70-200 f2.8 with medanones would be 2.0 (full frame conversion would be f4.0) The Panasonic 35-100 f2.8 (full frame conversion would be f5.6)

I love metabones speed booster for video work with manual focus + GH4. However I also take some still photos of kid's soccer games and I'm wondering if there's any EF mount lenses that I can use for medium to fast action still photos. I have Sigma 18-35mm with SB and the autofocus is OK for portrait photos but not for action photos. I'm worried that other longer lenses (Canon 70-200mm, Sigma 50-100mm) might have the same autofocus speed as Sigma 18-35mm. Any thoughts or comments? Thanks...

Does the speed booster actually helps with bokeh, or just the amount of light? Awesome video as always. I wish you'd post more... we enjoy your quality videos a lot. Cheers.

Hey, awesome that you posted a new video! I'm just getting into m4/3 and want to make videos so I got a hacked GH2, and am now waiting for my 1.4 50mm FD Lens. Is there a focal reducer that you would recommend, that wouldn't bust my wallet? Thanks for the videos, they're easy to understand and nicely made :)

l love your videos and I've learned so much thank you. I'm a director and I own a couple of production companies here in LA. I've been getting more hands on with cameras and learning so I can increase my skill set as a director. Question.. for commercials and promos I have a drone. The inspire 1 pro x5 which is a micro 4/3 camera. Also the osmo pro which uses the same camera. I'm looking for a good 4/3 lens that gives me a nice film look, and shoot in low light a lot and love the speed booster I use it on my Sony A7s. What do you recommend as far as a 4/3 lens that will give me a smooth film look, wide and normal.. I really dont use telephoto... maybe i would on the drone. Any suggestions would be greatly appreciated.

Hello. First of all I want to congratulate you on the excellent videos of the channel! Congratulations! In relation to the speedbooster, I saw some on ebay rather cheaper than those of the metabones. You know if they're worth it? Are they to be avoided? Or do they get good results? Thank you

Does this speedbooster work with the EM1 mark II?

Hi! I really like all the informations your giving with your videos :) Now I have a question that tickles me. I'd like to buy a focal speed booster for my OM lenses like yours BUT, I'm not willing to pay that much as I live in Quebec, Canada. It's about 25% more expensive because of the exchange rate. So I was wondering, if I buy an adapter ring for OM to Nikon or Canon then a Turbo speed booster II or a Commlite, would that be a functional combination? Or maybe it'll be more simple to sell all my older stuff and buy micro 4/3 lenses which will be more expensive? Your opinion would be much appreciated. Hope I'm clear enough as my first language is french. ;) Thanks again!

Very nice review! Now I want one! :) :)

Great video -- videos I've watched say that the speedbooster works well for video capturing -- what about for photography?

loving these videos. Any chance of a review on the 9-18mm Olympus lens? or have I missed that one? I'm considering purchasing one for my Olympus camera

For a Panasonic G7 and Sigma 18-35, should I get the 0.64 or the 0.71 speed booster?

Two questions/comments which are not photography related: 1.) is that a collection of manga behind you on your bookshelf? haha. 2.) I think a former manager/boss of mine is in that example photo you gave about the soft image being compressed down to make a sharper image. Small world if it is.

Great Video

Welcome back! :D, I'm thinking bout buying a m42 speedboster for both Pen EPM1 and EM5. Metabones is way too much out of budget, how bout Focal Reducer Zhongyi or the generic Roxsen one? Do you have any plan to review that? :)

I wish they'd offer more than just a single metabones booster for M43 cameras D:

This channel is fucking awesome!

Hey I have a GH4 with the last version 2.5, but I want to install the V l log, I have to remove version 2.5 or I can do about it???

Remember the aperture is affected by the smaller sensor just as the focal length is.

do ppl still use these with modern lenses? Like on a Panasonic 8-18mm f2.8 lens on the Panasonic Camera body?

Awesome channel man... I am getting a g7 with a 14-42 tonight in a trade for a canon L lens I have... I own a few Olympus om lens's, you have given me the information I needed to make this decision comfortable for me... I have a 50mm 1.4, 100mm 2.8, vivitar 19-35 f3.3-4.5 and a vivitar 17-28 f4-47.5 all om mount that I want to use.. What adapter or focal reducer do you recommend to get the most out of them.... p.s. im shooting all video with this rig so AF has no bearing... \

Speed Boosters (focal reducers) are great and you are right about the angle of view and sharpness advantage but what you said about aperture is not correct, Tony & Chelsea Northrup made a video about that. When you put a full frame lens on a crop body you have to apply crop factor to both, focal length and aperture, so by using speed booster you are not getting more light than the lens was designed to gather, but instead you are reducing the aperture "crop factor" making it closer to nominal 1.4 i your example.

Can you boost speed even your not adapting from a different lens system?

will this work on a leica or Panasonic lens?

How well does it work to micro 4/3 or old FD mounts to cameras. I did see that some of them are pretty bad and wile it does add a whole extra step of light it ruins the focus so you need to step it down anyway.

Thanks Mark! Do you still use the Domke's bag or did you get anything else.

Great video! Thinking about buying this speed booster... what about manual aperture control? The aperture stays open on my Zuiko 50 f/1.4 until a photo is taken. Are you able to adjust your apertures manually while using the speed booster? Thanks!

Great video. Is it possible to enable focus peaking if I use speedbooster with old OM lenses?

Wow, thanks for this review!! I had not heard of this product, but I *need* one now! I have the em-5 mkII and I picked it because I'm an Oly fanboi. I have been shooting OM system cameras for quite a while. I have the adapter from Olympus, and had no idea I could get back some of my wideness along with free speed! I have some of the same lenses, some of which were my dad's. I've got the 50/1.4, the 24/2.8, the 35-70/3.5, and recently the 28/2.0 and the 180/2.8. One annoyance of mine with the Oly adapter is that some of my lenses (perhaps all, I need to test it) want to focus past infinity. Does this suffer from that too? How does it fare with regards to chromatic aberration? Thanks again!

I have the Pixco which was 79 dollars. It has two elements not one. Total rip of at 5 times the price.

Shout out to Lucas Barton.

But its super expensive :/

thank you for this review, which I just saw now. I was wondering whether there are any other speed boosters for the 0M mount lenses other than the meta-bones at this point? I have not found any, and I am interested in getting one of these as I have quite a few old OM mount lenses. also, I have read that the flange on some of the 0M mounts can cause problems as you noted in this review. However it does not seem as if you have had any problem with a couple of the lenses that I have. Does anyone know whether the meta-bones 0M speed booster works with the following lenses (obviously, all 0M mount): Sigma 28 mm wide-angle (which I probably will not use), and the following Zuiko 0M lenses: 50 mm F1.4 (which you profiled so assume it works); 50 mm F1.8; 50 mm F3.5 macro; 85 mm F2; 100 mm F2.8 (which you also profiled so I assume it works as well); 135 mm F2.8; 180 mm F2.8; 200 mm F4; and 300 mm F4.5. Thanks much.

This thing is like $600. You might as well just buy new proper lenses for any micro 4/3 camera

welcome back nigga!

BEST Commlite BEST

Yeah but 649.00 for speed booster it quite a bit but oh well :)

Why does this seem like camera porn? I half expected to see you in bed smoking a cigarette with the Metabones next to you. LOL. I just got one today and was surprised it doesn't even have a manual or anything, so I have to crawl around the web finding out how everything works. You are right about it being expensive. $650, but it is either that or buying MFT lenses that I don't really need.

Please articulate your words it sound like you are mumbling nonstop.
