This is the third video I've seen by you, and you're quickly becoming my favorite channel...in the world, on any topic. The production value and accuracy and visuals are just absolutely insanely well-done. Thank you so much for what you do.
This video contains INCREDIBLE amount of ACCURATE information and amazing way to express it with visuals !!!!!!! Cannot truly say enough to be fair on the AMAZING EFFORT !!!! Congradulations !!!!!!!! One question , please : Can i use the Sigma 18-35/F1.8 with the XL0.64 Speedbooster , if i decide to use ONLY the 24mm-35mm Focal Length ??!!
Thank you ! I really care about the 9 minutes you spent watching the video, as much as you cared to watch it. Interesting, I'll test that when I have an XL in my hands and let you know. It should actually be OK because I've already used a (Full Frame) 5D Mark II with the 18-35 set at 35mm, vignetting was only very strong at 18. Let me check that once I have an XL to try !
@@zebrazone I really appreciate your response and your interest. Your behaviour is exceptional. You stand out among RUclipsRS , like a sunshine into the darkness. BRAVO,BRAVO,BRAVO !!!!!
When I use the sigma 18-35 on my GH5 with the Xl 0.64 Speedbooster it works the hole focal length as long as I'm filming. But with photos it starts to crop at around 23 when I'm in 4:3 mode. Don't know if its the same with the Blackmagic Pocket 4K? But they should have about the same size on the sensor. And with that camera you won't be taking any photos I'm guessing. @@HollywoodweddingfilmsGREECE
@@hatakekakashi938 Thank you for your input. Unfortunately Pocket 4K has a sensor 10% bigger/wider than GH5. Pocket 4K = 18.96mm GH5 = 17.30mm As a result , it creates significantly more vignetting in the XL speedbooster. But i am not sure which focal lengths are affected by this , on the Sigma 18-35.
@@HollywoodweddingfilmsGREECE I rented BMPCC 4K last week, it came with Metabones Speedbooster EF/BMCC. When I've tried it with Sigma 18-35 and few Xeen Cine lenses I've noticed some aberrations and vignetting in the corners. I switched Metabones for my EF/M43 XL (x0,64) and image was crystal clear.
a lot of people dont want the sharpest lens, so the viltrox would be perfect. Anamorphic lens do the same thing, and I love aberrations. It adds so much more to the camera, instead of an old boring sharp lens lol.
it is really a difference in sharpness, but with viltrox the problem is that you have to "tune" it correctly. This glass can be moved closer or further to the sensor. That solves also a lack of sharpness in the infinity problem. Great content! cheers!
Unless you are making money with your cameras, Viltrox ALL THE WAY. There is absolutely going to be better footage with a $700 adapter vs a $70 adapter. Metabones overcharges to much and if they were in the $300 max range its still overpriced but I would have considered it. I have a Viltrox myself and work has metabones, yes Mete is nicer but for personal use, the price cannot be beat. I expect 10 times better performance for that price and it was better but not at that price. But again, Metabones is meant for those doing this for a living so they will charge high prices, I do like de-clicked on Metabones where Viltrox is clicked. Viltrox is all manual, a BMPCC will not use the cameras functions for Iris. Metabones is like Autodesk, they charge so much because pros use it and can afford it, but their is the cheap version with far less for non-pros.
I have an active Canon EF lens with a Viltrox speedbooster. I can definitely confirm that the Viltrox will most definitely allow for electronic control of the iris, autofocus, and will allow lens stabilization to work.
hands down the very best video on this topic across the entire youtube. superb production value and presentation. I hope you have a video like this on every gear topic. would literally save me hundreds of hours of research.
Quite possibly the best tech review video on RUclips, and most definitely as it relates to focal reducers. This the best video in this category, by far. Thank you for this content.
This by far the most detailed comparison of the speed booster I've seen yet and probably ever will. I actually have viltrox adapter on my Gh4 with sigma 18-35 and for the most part I think the image quality is sharp for enough. It's very good to know the differences between the two. I might get a speed booster by metabones once I get enough money from the Gh4. Despite the shortcomings the viltrox is just an incredible adapter to get started with for the price.
DUDE!!! JUST THANKS MAN!! i was thinking about this, about there was another type of adaptor with better glass, saw about metabones and all of the sudden, all this type of question, came to youtube and you gave me all the answer! thx man!! cheers!
Really great comparison here. I had both the metabones and the viltrox speedbooster and never noticed I difference in sharpness in the center or edges but your test do show quite a bit of difference in the far corners. Great review
@@zebrazone no I think you're review was accurate and very well put together I just think that I was not pixel peeping or really looking at the details in the corners. The metabones is definitely the superior speedbooster. For most people it's just about whether or not the Price Is Right.
The production value of this video is STUNNING! This is the first video I’ve seen from you and I’m extremely impressed. Lots of good unbiased information and no time wasted. The graphics were very professional as well. I’m definitely subscribing!
Great video, I've most definitely noticed the edge blurring from my viltrox at 18mm when getting wide shots with a deep DOF. I always wondered if it was the adapter or the lens, now I know. Thank you!
Seriously, this is turning into my favourite youtube channel. I am consistently impressed by the amount of work you put in your videos, and love the fact that the BMPCC4K is featured a lot, since I've recently ordered mine. Great job!
@@zebrazone Yes, believe me I know 😊 I feel it should be emphasised at times when it's bleedin obvious. Again, top notch work. And best of all, very trustworthy, which should be your first goal!
very nice video, I remember when the metabones speedbooster was announced many photographers were very confused as to how it was possible for an extra lens to increase the aperture since all they new was teleconverters... some even downright refused to accept it. but actually those closeup lenses for macro stuff do the same thing, except with those you obviously loose the ability to focus on infinity... anyway, thanks for explaining it so well, I hope no everybody has understood how it works...
Done. Subscribed. Saw your video yesterday and thought, okay... this is good. Was searching today for the viltrox vs metabones and I find you again with an incredibly specific problem I've been searching for online. Amazing work!
Thank you. One of the best and most well done videos I have seen for a long time. I really appreciated the depth of understanding I gained on a topic and your use of visual aids and graphics. That is all very relevant for me right now as I'm about to buy the BMPCC 4k camera and continue my journey of discovery in this fascinating field.
Bro your videos are always awesome. Entertaining and informative. I never thought I'd get to use a Metabones Speedbooster but I got a kit that came with it. I can't wait to see what it does.
As always, great and unbiased work here and backed-up with solid visuals. We always look forward to your videos when we're getting new gear. Keep up the great work.
Notifications are definitely on for this channel. I aspire that as I start my RUclips channel I can attain somewhere near the level of quality and attention to detail you put into every one of your videos so far. Keep up the great work, cheers.
Your videos are insanly great and this one doesn't make a change ! 😍 The image, the editing, the sound, the music, the informations and the clarity of it makes it so good! You're clearly a step upper than all the other tech reviewers.. Bravo! 👏
you are the best content creator in this theme. Your style is very fresh and new. I feel you know something what i need to know :D Thanks informations!
Your channel is very interesting and useful! I rarely subscribe to channels, but I subscribe to yours after the first video. The video was shot and edited at a very high level. Your videos are very informative! Please continue. PS: noticed an mistake at 00:07:08 - mixed height and width of the full-frame matrix) but it is not essential
Once again, this channels is fucking AMAZING!!! Great job guys, keep it up, so much useful information, you totally bring a whole new level of clarity and production value to RUclips!
I have 2 GH5 and 2 GH5s for my production house, 2 paired up with metabones and two paired up to vitrox. We’ve used them all interchangeably and randomly amongst all 4 cameras. Other the then the perceived quality difference being higher on the metabones there is no difference in the footage. None. On the viltrox you are required to adjust the lens manually to set infinity focus (you can do a quick search on RUclips for a tutorial on how to do it) it’s really simple though. Cheers
Yep I did this infinity focus adjustement. In practice I think my usecase was very specific. Differences appear wide open only. Or maybe I got a wrong unit. Glad it's going well with you !
Excited to say that I was here before u got to 6 digit subscribers. 6.4k subs and counting. Crazy visuals and lighting. Ur hairstyle and sailor style shirt is unique too. Got ur own style.
This lesson was brilliant! Maybe I am slow, because I had to watch this a few times as I was confused about lens compatibility w/GH5, but now I get it. Thank you.
Excellent video. I think the problem with Viltox or Chinese boosters is the quality control, the majority are very good, some are correct and a few are just crappy. I agree with you about image quality, but if you plan to use pro lenses, not sure a cheap booster (or even an expensive one) is an option but when working with old lenses such as Russian M42 or T2, the ultimate sharpest is not the aim of the booster, it's more bokeh (especially in MFT) and in this specific case, even the low cost ones do perfectly the job. Personally, I still work with 120mm and 35mm film cameras and of course use the lenses on my mirrorless cameras, because I love the render of those old lenses, color, bokeh, imperfections, flare and the manual focusing ... in one word, the character . I prefer not to use adapted AF lenses because often, there are AF (speed or accuracy) and back/front-focus issues. When I need to have sharp, perfectly controlled images, I prefer to use "native" premium or pro lens, ideally fixed focal. I use zooms only when I travel. About the lens attachment, with Viltrox adapters (not only boosters), on MFT you need to make a little bit deeper the hole connecting to the camera (on the MFT rear mount) to be sure it locks properly. I had this issue on Olympus OMD-1 (both mark II and III) and on OMD-5 mark III but not on OMD-5 (mark I and II), probably Olympus changed a little bit its connector to reduce use of third-parties adapters and/or to improve something but to be sure the connection works, the small hole must be drilled +-0.5mm. It has no impact on mount to older Olympus or Panasonic cameras. I had the same issue with some other adapters I bought or I printed.
Other comparisons show that the corner sharpness on the viltrox improves significantly once you stop down to 2 or 2.8. Also, the Sigma 18-35 is an apsc lens, so it may be better with full frame lenses. I personally think that it is better to use a full frame stabilized lens like the canon 24-70 f4 on the BMPCC4k/Viltrox setup.
This video appeared in my feed, and thanks for that! I have both Canon and Olympus gear and have seen these adapters from Metaboned and Viltrox. Now, thanks to this excellent explanation/test/review I know I should not be a "cheapo" and buy the Viltrox. 🤪
Bonjour 8:21 Top Right Corner 8:24 Lower Right Corner And yes, this is the proof that your copy has an issue (QC) and as very nicely you described in the early part of the clip, about that mounting gap.
I don't have a Metabones Speed Booster to test against my Viltrox EF-Eii Speed Booster. However, I am fairly happy with my Viltrox, using it with Canon EF lenses modified for use on the Sony APSC A6400 and A6500 cameras... I use this almost exclusively for portraits so the unsharp edges do not bother me to any great degree and, perhaps because I am only using the center portion of the frame, I don't notice the unsharp edges too much. I also have an inexpensive M42 to E-mount speed booster which I also use primarily for portrait work. I was able to get the Viltrox EF-Eii Speed Booster for right about $100 (U.S. Dollars) on-line. Since I primarily use native e-mount lenses, except for portraits, the Viltrox provides an economical accessory for my e-mount APSC cameras. I have noticed that my EF 70-200mm f/4L IS and 100-400mm f/4.5-5.6L IS ii lenses auto focus better with the Viltrox than with the Metabones IV and Sigma MC-11 adapters...

Other comparisons show that the corner sharpness on the viltrox improves significantly once you stop down to 2 or 2.8. Also, the Sigma 18-35 is an apsc lens, so it may be better with full frame lenses. I personally think that it is better to use a full frame stabilized lens like the canon 24-70 f4 on the BMPCC4k/Viltrox setup.

I don't have a Metabones Speed Booster to test against my Viltrox EF-Eii Speed Booster. However, I am fairly happy with my Viltrox, using it with Canon EF lenses modified for use on the Sony APSC A6400 and A6500 cameras... I use this almost exclusively for portraits so the unsharp edges do not bother me to any great degree and, perhaps because I am only using the center portion of the frame, I don't notice the unsharp edges too much. I also have an inexpensive M42 to E-mount speed booster which I also use primarily for portrait work. I was able to get the Viltrox EF-Eii Speed Booster for right about $100 (U.S. Dollars) on-line. Since I primarily use native e-mount lenses, except for portraits, the Viltrox provides an economical accessory for my e-mount APSC cameras. I have noticed that my EF 70-200mm f/4L IS and 100-400mm f/4.5-5.6L IS ii lenses auto focus better with the Viltrox than with the Metabones IV and Sigma MC-11 adapters...
