 Hi, so I'm Daniel Ehime, Director of DP and Colorist and we'll be looking at today's lens test This is a commentary on the Loa Oom, 25-200 So we'll be testing the anamorphic With I mean with the rear anamorphic adapter and also without the rear anamorphic adapter So full disclaimer. I'm not by long shot an optics expert in Lens mechanics or lens. So this is just somewhat scientific so I Would allow this culture so you observe a lot But I would advise that to watch this and know more about it Or you should watch on the biggest screen possible and the highest resolution possible There'll be like a side-by-side and we'll do some flat test We tested the lens at t2.9 and also at t4 a couple of things we're trying to see was the influence of the rear adapter what it does to the image and close focusing and the flare characteristics at t2.9 and also at t4 and The stop of light loss of which you could see some veiling that's happening at the 25 millimeter and this veiling is progressive but As we go in or closer in terms from the range going from 25 up to 100 the flare significantly reduces drastically and On the 25 mil as we tell the rear anamorphic adapter There's just those interesting characteristics that was available via the rear anamorphic adapter and the longer available or somewhat different again over on the color of the glass because if we look at the one with the anamorphic adapter when we When we Tested on the why the test was on you'll see that the rear anamorphic adapter somehow warms up the image Now we have the flare test going on right now at the moment But if we look at the t4 test and you can see how the tone size almost like there's some kind of Reduction in sharpness and some kind of like most of the micro details that have been mute like There's it's not as Sharp as it should be Which is what I believe it is designed to do to give it the loss of sharpness and focus follow-up That happens across the frame which is not as apparent when you take on the adapter and get that extra stop of light back And this is quite a unique characteristic though because I find it very interesting and In terms of how it makes the lens work another thing I observed When the two side-by-side test comes up if you notice the background from the tree to the girls hair When you see on the the one with the adapter looks closer than the one that has that do not have the adapters Almost as if that it pulls the background in a bit and although we get to lose some Framing based on the squeeze ratio and all that happens, but it pulls the background in and that's just interesting in such a way how the lens gets like compressed space and I did with the flaring characteristics and the bokeh we get to see and How you have some rainbow characteristic towards the edge While we're doing the bokeh test Let's say when the tip comes up again, I'll go for that again. It was interesting to see how You get this whole Almost over bokeh skewed bokeh to the end of the lens but the center is usually like rounded It becomes very much much apparent when you can see it on the hundred mil But so this lens Was straight from la like fully bought not sponsored upon fully purchased from the company It's supposed to be powerful. But what I did observe, okay now in the 35 mil took one line I'll come back to that taught in a bit Now here's what I was talking about the bokehs and how they actually Fall off and how grounded they are you get towards the edge. There's this whole Ovalness that happened to them, which would notice more you get done in the center with a little bit more grounded But they're not like perfect circles as you will see because we also test that the Lauer against the Canon Sumire is the Canon C&E's and also Leica Sumochrons You get so a couple of that will be coming up in under batch of videos because It's gonna be like what quite long if we try to fit all of that into this you get but something like I said that I noticed was that When we actually like I'm put woodlands Side by side like I shouldn't focus and pull and pull It was not as sharp as it should be like when you focus on like a What 100 mil or something I pull out back like a 25 Somehow the focus just shift just so slightly and there's some now I don't know this or not enough to notice we could have to do it probably the way the inner elements of the glass moves in the Interior of the glass sections, but something that I get that I did notice was that The distance between the camera or the plane of the sensor to these characters was about 12 feet Up until we got to above 50 mil the marking on the lens kept saying 20 feet They were as close to cross 50 on the 50 mils the markings to reality and markings on the lens began to correspond Then it makes sense to me though because in my head I was like Yeah, it really didn't make sense like why would that happen? I'm still trying to investigate it and figure if I screwed up something or if there's something I didn't take into account You get now you can see some of the failing rainbow flash that happens when we're actually flaring on the 35 but So pushing more you get to see what I mean by the background pulling in The lower adapter and the one without the adapter and how they all Respond optically I kind of do like where The Low lens the amorphic adapter is that especially the focus fall off and how that there's not just that sharpness It's just this feel I can put into Technical words you get there on that five teeth or you can see how the broker here is actually full circle No double blades like with the others, but after here you get to see more double blades That goes across the book on these on this is the 35 mil now on a T4 Yeah, so the lens is quite interesting has unique characteristics and Like a different length and also there's definitely a Push to the warm tone when you're using that the adapter as opposed to I kind of like what it does to the skin you get supposed to The The coldness of the glass when it's action is on without the adapter Nonetheless, it's still an amazing and it's not not the least you get I like what it does the skin turns like It just reacts. Well, I'm the way it actually rolls off the highlight. This is all in lens now. No softer. It's just lens and The rougher that because it was shot on the Canon C 300 Mac 3 and since my raw light and Yeah, we just went on it. You get see how the highlight actually rolls off like when we actually like going into the frozen 500 that is actually Blasting through the lens with as much force as it can on I think that was set at about 25% to do Yeah, the Fresnel in front to actually focus it so we can see how that actually happens Oh god, I like the flare and it happens on this Because there's some It just reacts differently. You get depending on the angle of what you hit the glass You get to get different characteristics of flare and how it plays that and also if you're using the The anamorphic adapter, which does not give you the fun on morphic elements So what that means that you don't get the extra field of view. You do not get the overall What you get? It's just a very Minor squeeze squeeze factor that actually gives you the 235 Axial ratio on the 16 by 9th sensor, which is quite useful and the fact that the anamorphic adapter could also be Rotated vertically we didn't do that here, but you could rotate it vertically and also get a 4 by 9 Expect ratio for me Now we are on the 50 now and you begin to see how much the background becomes closer And that focus fall off that actually talked about and how that actually plays in And it almost feels as this extra maybe is the warmth but This image feels a lot more rich with the adapter though. I really don't know. I can't replace my hand I'm still trying to wrap my head about around a couple of things that are actually going on Within the lens why I actually test to see What's there and what's not there you get? At some point Yeah, so you can see how it actually looks and how it actually holds up you get on this Which will be a lot more interesting. We'll compare it to the other glasses which will come up Which will be next video I'll get to put up So, um, I will keep quiet now and I'll let you just like Go through till the end because I believe I've talked for too long and um, yeah Leave your comments in the Leave your comments below. Let me know your thoughts. Let me know what I should have tested for let me know What went wrong or what was not taken to account or I don't know anything you picked up. I didn't okay Yeah, thank you for your time and um, I'll leave the video up until the end
