Rokinon Cine Lenses: 16mm and 12mm on BMPCC - Battleship!
HTML-код
- Опубликовано: 9 фев 2025
- This is my test of the Rokinon Cine 12mm and 16mm T2.2 lenses, using the Blackmagic Pocket Camera. It is also probably the dumbest thing I've ever made.
ISO 800
Shutter angle 150
Both lenses set to around T4.0. They are at their sharpest at 8.0, which was not tested here.

Some pretty neat footage haha. Every time I see stuff like this, shot on Samyang/Rokinon Cine glass, I just can't wait to get my hands on it for an upcoming shoot.
Quick question- loving that song. Name at all? Thanks :D
It's hard to describe but I'm starting to notice the Rokinons have a certain look in the highlights it seems. What do you think?
Sometimes the highlights are blasting and other times they roll off extra smooth. In your test I thought the white pegs rolled off beautifully, but the texture on the table looked really contrasty. What's your experience grading for the Rokinon Cines?
That, I think, had to do with the fact that I was using hard light sources, my inexperience with exposure in this video, and the BMPCC's sensor. The main thing with these lenses is they're a little soft wide open.
For a better look at how the lenses grade (not expertly), you can take a look at this short I made: ruclips.net/video/2Z7v4peBlOE/видео.html
***** Thanks!
Man, I need some help. For a while now, I've been piecing together some stuff for a BMPCC setup in B&H, and thing is I'm already on a tight budget as it is - I have a lot of other bills and expenses for film school (it's so damn costly lol) - anyway, initially I planned on getting two lenses - the Panasonic 14-45 and a Rokinon Cine 85mm. Basically I've never used a BMPCC so I've no idea how the crop factor will affect the lenses that's why I was gonna get two lenses. But I've just had a huge setback in my savings so looks like I'm gonna get just one lens - I might be stuck with it for a while. I just really need a new camera right away, one I can use for school and stuff - and I've been obsessing about the BMPCC for a long time now. I'm also dying to try out those Rokinon Cine lenses, that's why I'm pushing to get a Rokinon Cine lens as the main primary lens I'll get with my BMPCC. I just wanted to ask you if either the 16mm or the 12mm will work fine as a primary lens, you know, one that will do alright in just about any situation, and I mean since because of the crop factor, they probably won't be as wide angle as one would expect, I gather. But as I've said, I've never dealt with the crop factor of the BMPCC so I'm going to be purchasing a lens with no idea how it's gonna perform with the BMPCC, and since I'm constrained right now budget-wise, I'll have no room for experimentation, so I really need to make sure what lens I'll get can deliver. But hey, those C-Mount adapters aren't really that expensive so I'm getting one and hopefully try to get some cheap vintage lenses later on, but no doubt I'll have to make do for a while with what I'll get now. I just wanted another opinion - cause I've been asking around online with people who have used Rokinon lenses what they thought would make an alright primary lens considering the crop factor, and so far I've been getting sketchy responses, idk - and the reason behind my choosing the 85mm in the first place is one guy told me it would make a great primary lens considering the crop factor, but isn't it the other way around? Anyway, I hope I'm not already taking too much of your time by this lengthy post, so sorry about that, it's just that I'm so OCD when it comes to these sorts of things lol. Would appreciate any thoughts you might have, thanks!
+MalloryJacobPacheco I'll explain the crop factor really quick. BMPCC is 2.97x crop, which means you're using a tiny portion of every lens you put on the camera (even MFT lenses). 12mm on the BMPCC gives you the frame size of a 35mm lens on a full frame camera. 16mm gives you the frame size of a 50mm. 35mm gives you the frame size of an 85mm. If you got an 85mm, it would give you the super-duper zoomed frame size of a 250mm lens, like those long sports lenses. You would have to stand very, very far away from every subject.
But, frame size shouldn't be your only concern. A 12mm lens, though you're only getting 35mm's worth of it, is still significantly super-wide and distorted. It's still a 12mm lens. Everything will be in focus. When using the BMPCC and wide lenses together, kiss any ideas of shallow depth of field goodbye, because you won't have it.
It's hard to say what you would need as a "primary lens" since that would depend on what you intend on doing with the camera. I have the Lumix 14-45mm. In fact that was the first lens I got with my Pocket. It's as good as any as a starter lens. You should mainly be worried about your technique and not your gear. I wouldn't expect to make money using that lens, but it's as good as any to start with.
This camera will never be a full frame camera, so I would stop as soon as possible in making any comparisons. Embrace the crop and don't worry about going too wide. If you are okay with not being able to zoom in and out, the Rokinon 35mm was my favorite of the bunch. It kicks the 16mm's butt and it blows the socks off of the 12mm. If you really want to save money, don't get the cine versions. They look and feel nicer, but they use the same glass as the photography lenses.
+Trace Myers Thank you so much man for responding - and in detail! You have no idea how this helps me out. One more dumb question though, you mean the Rokinon cine lenses don't have a zoom ring? Also, is there really no chance of getting a shallow depth of field with the 12mm/12mm - even on ND filters?
I mean it's not that I use zoom a lot but I'd like to have that option - for instance I love "zolly" shots. Basically what I need is something that can last me this year in film school - or even until the next term/semester. And now that I think of it I do use tight shots a lot and a lot of zoomy-shaky Battlestar Galactica-esque cinematography - you mean I can't do that with the cine lenses? Because it would be such a shame I so badly want to try out those de-clicked manual aperture rings! But well yeah, as of the moment I'm seeing the 14-45 as a viable solution. But still, so hard to decide haha.
To get a better feel for the rokinons, check out this thing I made a while back: ruclips.net/video/qtBOfXoxQKo/видео.html . 0:03-0:20 is the 12mm and at 0:40s is the 35mm.
+MalloryJacobPacheco The Rokinon lenses are 'prime' lenses (12mm, 16mm, 35mm, etc), which means their focal lengths do not change. 'Zoom' lenses (14-42mm, 12-35mm, 50-200mm, etc.) can shift the elements inside the lens and effectively change focal lengths. That is the 'zoom' effect.
Shallow depth of field comes with using 1.) wider apertures (lower F and T numbers, such as T2.2 or F1.8) and 2.) longer lenses (larger focal mm number). The wider the aperture and the longer the lens, the shallower the depth of field. So, while Rokinon's 12mm lens is T2.2, which is a nice, big open aperture, it is still a a super-wide lens. For the background to be out of focus at all, the subject would have to be within 3 feet of the lens.
Usually for a zoom lens to be as good in quality as a prime lens, the zoom will cost 2-3x more.
Dolly zooms are very difficult. You have three core actions at work: the dolly, the zoom, and the focus. If you have somebody to pull/push you on the dolly, you still have to both zoom and focus at once, working the rings in opposite directions and at opposite rates. The Lumix 14-42 is a kit zoom lens, which isn't going to make it any easier. The zoom is sticky (not smooth) and the focus throw, or the distance the focus ring turns between closest focus and infinity, is tiny. Also, the aperture (the iris of the lens) on the Lumix is variable, which means your shot will get darker/gain depth of field as you zoom in. And vice-versa, your shot will get brighter and narrow its depth of field as you zoom out.
So! Suggestions. If you want to be able to use the 14-42mm range of focal lengths in one lens and be able to zoom in your shots, go with the Lumix. If you are okay with zooming with your feet, and you prefer comfort, ease of use, and better optical quality, go with a Rokinon. Probably the 35mm - especially if you like tighter shots. If you want to pay the premium for the cine lenses, that's up to you. They are better for video, but not so much so that you shouldn't save your money and spend it on another piece of gear.
If you don't have any stabilization equipment (shoulder rig, tripod), you're gonna want to go with the Lumix. The camera is too light to handhold. Your footage will be very shaky.
+Trace Myers Oh my god, okay so now I know. Sorry you had to go through all that explaining, it would seem I'm still a newbie at these things haha. I guess the camera that I'd been using this past year did not really give me anything to learn from.
Once again, thanks man for taking the time - this really helps me out! I guess I would have gotten the 85mm if it weren't for you, haha. Alright, I won't be taking any more of your time, I have some deciding to do apparently! Thanks!
Mahler... nice touch.
Lins + metabones?
No I wasn't using a metabones here.
@@TraceMyers26 What kind of adapter did you use then?
@@verovang No adapter. Rokinon makes MFT mount cine lenses. Heres the 12mm (express.google.com/u/0/product/5307399556299869627_6796312437117243337_1057813?gtim=CMuphLKyyoHvMBCSqqGywJ6OojsYgJOrsgEiA1VTRCjglMTlBTCVyEA&gclid=Cj0KCQjw1pblBRDSARIsACfUG13ET5o_aLYp3nmJVxllwJdipmjtDSeE2g1AtFaUHNjp9Q8mZclHHt0aAlxUEALw_wcB)
