Hello guys, my name is Tom Amtus and in this video I'm going to show you really exciting and really cool camera lens test that I did using these three different Metabone speedboosters that I've got up here. If you don't know anything about these adapters, they're basically lens adapters but they not only do they allow you to put let's say Canon EF glass or there's also other versions for Nikon lenses and other lenses and you can put them on a Micro 4.3 camera like in this case I've been using it with the black magic packet cinema 4K camera but you can put it on GH4 GH5 and another Micro 4.3 cameras so it will allow you to put those other lenses on those cameras but it will also squeeze the image so that you can turn your Micro 4.3 image or sensor basically into a sensor that becomes like a super 35mm or you know APS-C size sensor or even a full frame sensor depending on which version of this you get so anyways stay tuned I'm going to show you guys all those exciting tests coming up so Alright, so now let's talk about the different lens adapters of speedboosters. I've got three here with me. They're all from Metabones and the reason is because I've tried some of the other companies like Ville Tracks and I forget what the other one was. But anyways, they weren't good. So I'm not even going to bother talking about them. Why don't they have a problem with the back focusing? I can add. Sometimes I could, which in lenses get infinity focused, some of them I couldn't. So these ones are three different ones and the reason is because there's one here in the center. That's my old trusty Metabones speedbooster that I've used with GH4, GH5 and a whole bunch of other cameras over the years. It's the 0.71 X crop factor. So it's very similar to the new Ultra 0.71 X that I have up here. It's the latest version. To be honest, there's really no difference optically that at least that I could spot. I mean, if you're really pixel-peeping and shooting test charts, maybe then you'll notice it, but they're both equally sharp. So that's the standard aspect and the ideal offer the same kind of, you know, it comes to distortions and the kind of characteristics that they looked at they give you. What I noticed the difference is really in that the newer one has some, I guess the newer better firmware and it will work with more lenses when it comes to out of focus or image stabilization, that kind of stuff. Since I'm usually working with cinema glass anyways, I pretty much don't care. So I'm just going to kind of throw this out by that. I mean, I'm going to carefully put it to the side. And I'm just going to concentrate on these two. So what's the difference between these two? Well, the one here that I've got is the Metabones speedbooster XL and that's the 0.64 X. You know, basically, yeah, basically the crop factor you could say this one is the old trial 0.71. Basically, they both work on the black magic packet cinema camera. Some of the other cameras you got to be careful because I don't know if you can see up here, but basically this one, the 0.64 sticks out more out of the bag. So certain cameras that have an actual mirror or that have the sensor really close, for example, to the mount could actually end up being damaged with this, you know, the packet cinema for camera, you don't have to worry, they both will work on there. And you can use both of these. Now, here's the difference and that's kind of where some of the confusion I know was and a previous video I did also. I kind of posted one thing or I wrote something incorrectly in the description, I had to correct it after and also some people I think seem to be misinformed. And what I'm talking about is that people are saying that you can only use the old trial 0.71 version that the 0.64 is not going to work on the black magic packet cinema for camera, but the reality is that yes, it will work. Both of them will work. It's just that this one effectively changes your micro for third image sensor and kind of make turns into a super 35 millimeter. So like an APS C size more or less image sensor, actually slightly larger than that. This one is effectively going to convert it to almost the same thing as a full frame camera. So what that means is that if you like that full frame look and if you like and you have full frame lenses, then you can get this one and you're going to be very happy. If you throw on their lens that's not full frame like, for example, the Sigma 18 to 35, you can see the edges basically because that lenses not a full frame lens. So that's something to be aware of is that you got to make sure that if you're going to get this one, you can only use it with full frame lenses because again, it's you're turning it into full frame camera, but it's going to work. It's going to work with full frame lenses. Now if you have full frame lenses and AP APS C size, you know, super 35 millimeter type of lenses, then I would say, you know, get this version, the 0.71. Yeah, you won't get as wide field of view. It's, you know, and maybe it's going to be a little bit harder to get in some cases, shallower depth of field, but this is still planning more than, you know, then, then really you're going to need to get a cinematic image. It's, it creates the same kind of image look, you know, that you get with, you know, most of the films that were shot over the last 100 years because most of them were shot with the on cameras, different cameras and some of them on film and stuff, but they were all shot with pretty much an image science sensor very close to this. So that's what I'm saying, just get this and you can definitely get cinematic images. If you like more of the full frame look and you get full frame lenses, then you can get this Excel 0.64 version of the speed booster. So that's where the only difference.
