Tried to explain as best as I could how a speed booster works relative to crop factor if you're interested. Plus an unsponsored real life comparison between the Viltrox EF-M2 and Metabones Ultra 0.71x speedboosters. Note that this is the MkI version of the Viltrox EF-M2, the viltrox EF-M2 II is better. Please correct me if some things are unclear or if I'm wrong :) Hope you like it !

Many thanks to my friends Claire and Mathieu for their time and help for this video to whom goes the credit for the performance in the comparison shots.
The video was shot with an URSA Mini Pro and a Sigma 18-35mm ART lens, the comparison footage was shot with the same lens and a Blackmagic Pocket 4K Camera (BMPCC 4K). But you can also use a speed booster with the GH5 , GH5S or other micro four thirds based cameras.

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 ??!!

@zebrazone 5 лет назад

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 !

@hatakekakashi938 5 лет назад

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

@HollywoodweddingfilmsGREECE 5 лет назад

@@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.

@NilsnLewinski 5 лет назад

@@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.

@christophershivers6257 5 лет назад

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.

@philipquaglino 5 лет назад

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.

@charlesoxley7242 2 года назад

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.

@MichaelNguyenn 5 лет назад

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.

@zebrazone 5 лет назад

Thanks Michael ! I agree. Honestly, I don't think it's worth upgrading if you don't feel limited. Save money for other more important stuff :)

Not sure if that would have any affect on what is happening on the edges of the frame using the viltrox. Cheers
