The REAL difference between CINE & STILLS lenses

[@DaveMcKeegan]

Just to clarify this is looking at cine lenses which are derived from stills lenses. The very expensive cine lenses that are designed as cine lenses have no focus breathing and are par-focal, which stills lenses generally don't have to reduce costs - but as stablemate cine lenses carry the same optics they have the same result

[@federicodecuadro5672]

Easy to see the difference in design in the image at 8:55. All the other expensive cinema lenses have optical elements protruding back from the mount, since you have no mirror in a cinema camera you can do this and it opens a whole world of possibilities in optics design.

[@corneliusdobeneck4081]

You forgot two important differences: 1: Cine lenses have a much MUCH longer throw on the focusing ring which makes it way easier to pull focus especially with moving objects. And there might be a chance when doing film that things move. 2: Cine lenses usually have the same color matched coating throughout a series which is not always the case with still lenses but makes a hell of a difference on set and in post production. All in all and in summary you could say that Cina lenses are much more precise then stills lenses hence the price difference.

[@DaveMcKeegan]

Very good points, although incidentally the focus throw on these 2 lenses is identical at around 270*

Never has the difference been so clear! The best explanation so far. Thank you!

[@Hello2U4s0e4r]

I loved the disclaimer at the beginning. Always concerned when browsing recommend videos and other reviews and that quickly made the video trusted and fun.

[@KhoPhi]

I appreciate the uniformity and consistency in the cine lens world. The still world could use that consistency of design.

[@fto5935]

Lol you never used a vintage Cook cine lens... Modern still lens series i.e. Zeiss Milvus are matched.

[@MarioAtheonio]

There's just a bigger incentive for it in film. If everything already costs so much, you're hauling so much gear around, and time is extremely precious, you really don't want to have to rent out and lug around a whole different mattebox kit for each individual lens. Also, you need a lot more consistency if you're constantly cutting between shots taken with different lenses.

[@TechnoBabble]

There isn't really a reason to match everything on stills lenses. Generally during a photo shoot you're not switching between 5 different lenses and you also aren't using accessories that are attached to the lens. I think most photographers prefer having their lenses cost as little as possible for the quality and features they provide while also being as small and light as possible, all of those things go out the window when you want all the lenses in a line to match.

[@BigBadLoneWolf]

I knew the difference between f stops and t stops, but you taught me about the rest . Excellent video

[@bravo4adventure988]

I had no idea, so I learned that part too.

[@RadicalEdwardStudios]

Many cine lenses do work hard to be different from still, optically. They try to avoid aberrations, make things more even across the glass, fix light angles, deal with reflection. The catch is that these are the ones where you end up paying a lot more than double for the same thing. And then, of course, all of those things you mentioned are also true. Focus breathing is also important, if that's compensated.

[@okebaram]

Why don't they put the same optic quality efforts into still lenses? Is it because movie production companies are more ready to pay for expensive gear?

[@RadicalEdwardStudios]

@@okebaram 1. I personally won't be buying a $40,000 lens for my camera. 2. Movie companies very commonly work by renting equipment. That's a great way to disguise real cost.

[@paulm8157]

Well done, Dave! Clear, concise, thorough, including “so what” factor. Does similarity of optical performance include color rendition and uniformity of optical characteristics across the cine lens line?

[@DaveMcKeegan]

I believe they'll be similar but not identical, since the stablemates are using the same optics as the stills they've have the same differences across the lineup as the stills do. But I doubt they'll ever get an 11mm lens to have identical characteristics to a 150mm macro for example

[@eidschun]

Very nice comparison. However, other than the better build quality (which I find dubious), the reasons cited for the increased cost of the cine lens and cine lenses in general - and I’m referring to fixed-focal length lenses only, not zoom lenses - really don’t make sense. After all, a slow focusing system simply requires different internal gearing; the focusing distances indicated on a stills lens can be measured and marked on the focusing ring; you can calibrate any stills lens to specific t-stops (and mark them on the aperture ring); an aperture adjustment mechanism without detents should be less expensive than one with detents, since detents are an added complication; etc. This leaves few plausible reasons why the cine lens is more expensive, such as, far fewer are sold in comparison to stills lenses, the typical customer is much better endowed than the typical stills photographer and can easily recoup the cost by renting out the lens, and there is perhaps less “focus breathing,” and less of a tendency to develop internal reflections from off-axis light sources, where the latter can always be blocked when shooting a still.

[@pcofranc]

Great info I knew some differences but have a more complete picture now. Would be nice to do a follow-up where you show off the focus pulling advantages of the cine lens.

[@DaveMcKeegan]

Great suggestion, although I only had the lenses on loan from Irix and have since been returned but it's something I'll keep in mind for the future if I can get hold of some other stablemate lenses

[@dangoldbach6570]

Thanks so much for explaining this! I haven't seen a comprehensive breakdown of the cine/still (as opposed to cine still film!) Lenses before. It actually makes a heck of a lot of sense that cine lenses standardize like that, it also makes me feel a lot better knowing that I can use my still lenses for videos and still get good results within reason! Perfect for people like me that dabble in both but don't want to lay out too much cash for something I may not really actually need at my level

[@DaveMcKeegan]

Absolutely Dan, I do a fair amount of videos but never use cine lenses as half the time I'm in front of the camera and needing autofocus, so to use cine lenses would also require a cameraman, and for the times I able operating the camera and using manual focus I fine the stills lenses still do I perfectly fine job for what I need.

[@draganmikki5688]

Most cine lenses have additional unit inside the lens which compensate 'focus breathing', which is another major difference. Great video!

[@tomastuoma]

Do you have any info on this? I was wondering about exactly that after using Irix 30mm. The cine version has pretty much zero breathing, but the stills version does. Clearly something is different in the optical design, but it's not the number of elements, or what they are, but it is something.

Every single thing is same, except gear focus and aperture rings, non-click aperture and longer focus travel. I'm starting to astrophotography and I need sensitive focus so I decided to buy cine version. But everone said "no that should not work for photo that is cine lens" I bought it anyway. Now I'm waiting for my lens and with the help of this video I'm very happy. Thanks a lot. I also watched a video about f1.4 lenses and f2.8 lenses. They shoot some pictures with f4 f8 f11 and they say "we don't understand why f1.2 one is expensive". That channel has 250.000 subs.

Wow, I really learned a lot! Great breakdown. IMO I'm not sure that the build quality and physical changes for focus pulling are quite worth double. Do you feel there is any premium being paid because they're most likely for professional use and "budgets" rather than "wallets" are paying for them?

[@DaveMcKeegan]

Part of it is the economics of supply and demand, with cine lenses being a much more niche product then the R&D costs and the costs of setting up new machines can't be spread across as many units sold

[@nathanryan8699]

Time = Money my friend. You have trained professionals expecting a certain work environment. Cine lenses cater to them. A single operator has serious diminishing returns. You can learn any kit for your own purposes. Group dynamics on a cinema shoot are a different beast. Build quality definitely plays a part in rental scenarios. Again, single operator/owner it's severe diminishing returns. Resell value may play a part, though.

AS a DP I want to make a couple of statements ; - Cine productions tend to use proper cine lenses, not derieved from any still ones. ( ranging from 5K€ to 30K€, and even more if we're talking anamorphic ) - Cine lenses DOES NOT have focus breathing, 99% of still lenses have that issue. - Up until 6 or 7 years ago, pretty much all cine lenses ever made ( since the 1890's ) were to cover Super 35, so essentially they are APS-C lenses. - They are built like a tank, but also design for easy maintenance if something break. - modern high end cine lenses are flawless, some are optically perfect, even by Zeiss Otus standards - Those lenses, along side all the equipment, are rented and not bought. a full set cost more than a Ferrari or Lamborgini. ( Panavision lenses ; the Rolls Royes of cine lesnes, cannot even be purchase by rental companies. ) - A full set of cine lenses have more focal choices ( 15mm,18,20,25,28,32,35,40,45,50,65,75,85,100mm....) - Only the DP change or allow to change the aperture, but he don't take in charge the focus ring, that's the job of the 1st AC.

[@willionaire360]

Thanks for the insight

[@DaveMcKeegan]

Excellent points Jeyycie, although those attributes could be put into a stills lens and sold for the same sort of price, but this was really more aimed at the stablemate lenses as I've seen a few people for example using cine versions for shooting stills believing that there are optically better etc

[@jeyycie3656]

@@DaveMcKeegan yes, but that's for small cine lens like the Canon cine primes with comparaison from the stills L seriers, which are optically identical. but if you take real cine lens, although you could mount it on your mirrorless, I don't think someone would buy a still version of a 50mm at 20 000€ and 4kg just because it takes nice pictures. ( apart from Leica users, even though 4kg is too much for them ) utility is more important than performance, but for cinema the more is better, and you hire the pepoele and get the logestics to make use of it, for photography, small video production or low budget films, that would be ridiculus, unpractical even. There's plenty of good lenses out there, especially with mirrorless cameras since you can adapt pretty much anything with it.

I think it's also worth pointing out that the price difference isn't just about features it's about their prospective markets. Stills lenses are for photographers who make a professional income (or nothing) Cinema lenses are (mainly) for movie studios who have enourmous amounts of money to throw around, and who will buy in bulk or as a set and save some money off that RRP. Most videographers I know just use stills lenses and produce awesome results. They can't justify the cost for cinema lenses.

Lighting, composition and editing are generally always the biggest factors when it comes to viewing things. Higher FPS is obviously useful if you wish to include slow motion elements while resolution probably plays the least important role, sure its great to have higher resolution and more detail but it doesn't really make footage look cinematic.

Aside from the markings on the top vs. markings on the side, if you get a stills lens that “ de-clicks” the f-stop, is there a big difference between the two?

[@DaveMcKeegan]

The de-clicked aperture is really aimed more for video shooters anyway so it's to make the lens more of a hybrid than a stills lens The other differences come in the geared rings and standardised front and filter sizes which the de-clicked stills lenses don't have but that's only a real benefit if you are shooting a lot with the camera on a rig

@@DaveMcKeegan May I ask you if there's any practical use during a shot of the external aperture grid and how is it eventually compensated? Okay, normally one would compensate with the shutter speed or the ISO, but since you can't change the shutter speed while filming, can you compensate with the ISO? Or its function is simply to quickly set everything up before shooting and you don't change the depth of field after you started recording? I hope my question is comprehensible!

[@DaveMcKeegan]

@@ItsJoeHut if I am understanding correctly you mean would you normally change the aperture in the middle of recording?

[@yohannsphotographyvideogra9542]

Looking for a good 12mm for video real estate any recommendations.

[@DaveMcKeegan]

Depends on what camera you're using for what's available

[@ddonate]

So most of the features you mention would explain a lower price tag on the cinema lens, not a higher one. Standardisation, click-less aperture rings, lack of electronics etc. mean lower manufacturing costs. The only feature that is indeed more expensive is the T vs F number calculation. I guess that it's more a matter of production volume, since cine lenses are made in much smaller numbers than still photo lenses. And their target customers are willing to pay the premium.

[@TechnoBabble]

Click-less aperture ring needs to be more smooth to operate and be damped better than a clicking ones. Standardizing the position of gears and the size of the external housing means means additional components or larger pieces being manufactured (think a 50mm lens being physically size matched to a 100mm lens, the 50mm now needs a larger housing than is necessary to just hold the optics). A lot of the time cine lenses also have colour matched coatings on the elements, even if the the optics are shared with stills lenses, another more expensive part of producing them.

[@rickymcc9072]

Hi Dave Thanks for clearly explaining the key differences, as a stills only (currently) shooter I had a vague idea about some aspects but your short primer fills out my knowledge gaps nicely. I probably need to start experimenting, but I'm a tad intimidated by all the extra kit (cage - sound mikes - ext. monitor - matte box - gimbal etc) many seem to quickly evolve into using. Then there is the editing and technique. All in all seems a big step. I'm pretty competent with stills but could do with a few more pointers (as well as experimenting time) if I'm ever to feel comfortable making "good" video. Is that the sort of thing you might consider covering? A few short vids on how a stills shooter can best get acquainted with occasional video?

[@DaveMcKeegan]

Depending on what you're shooting a lot of the accessories aren't absolutely necessary, at least not to begin with. Cages for example are only really useful if you are mounting a ton of accessories on the camera. External mics are certainly a good thing to have but if mounted on the camera make no difference to your workflow than if you didn't have one. Monitors are helpful to see clearer than your camera screen allows or are useful if you are away from the camera but I personally never use them these days as I find the camera screen to be sufficient. For starters I would just use the camera with minimal accessories and just get comfortable with shooting video and then build up as and when needed. But I may do a video on it at some point in the future.

[@g-low6365]

[@danlightened]

Nothing against you. Good informative content and a super chilled out doggo. But how can the mechanisms justify a 800 euro price difference? Cause as a photographer, my belief is that majority of the cost goes into the glass.

[@DaveMcKeegan]

Majority of it is supply and demand - the cine lenses require a new production line to create the different barrel designs and different mechanisms, but aren't sold in anywhere as higher volumes as the stills lenses and so the cost per unit has to be higher to cover the production ... Else they'd have to raise the prices for all their lenses which would reduce overall demand

[@murraykriner9425]

There have been stepless apertures on camera's since the 1960's, starting with the Yashica Electro GSN, which later saw use with the Minolta Hi-Matic and GT models in the mid-70's. All of these were adaptations on Rangefinders for the consumer markets. The earliest Cinematic lenses also followed that equation, with Bell & Howell, and even Kodak capitalizing on that technology. Even with the advent of gear driven, motorized, focus and zoom being on many of the he current video camera's being offered, why hasn't the still industry just taken the stops out of circulation with button touch, pre-programmed, focus and zoom to alleviate all this nonsense about having to dedicate a type for either one or the other. Transmitted light is really the end game in the first place, isn't it?

You could also mention, that most cine lenses are parfocal, which is not the case for stills lenses. en.wikipedia.org/wiki/Parfocal_lens . Although I can't find if Irix cine lens has that feature.

Great information. Your lenses and/or camera body sensor are dirty as heck, though. I was seeing multiple fibers, specks, etc., all throughout your video. I mean, a lot. Pretty convinced that in your couch scene, those are two specks off to the left of the frame. One above the molding and one below, shoulder level. Despite how good your presentation was, I could not spot seeing these fibers and specs everywhere to the point that it was very distracting.

It really bothered my OCD. I saw every little speck and thought "did he not see those?".

[@KungPowEnterFist]

@@EnterSpacebar I'm really trying not to be overly critical, but it was just so much. Even the bokeh had fibers and specks.

[@EnterSpacebar]

@@KungPowEnterFist No, I saw the same. It's pretty distracting, although the video was otherwise really well done.

It is also worth noting, there is also a distinct supply-and-demand aspect that drives the difference in pricing. It is very easy to complain about the seemingly absurd prices of cine lenses over photo lenses without understanding the economics involved(beyond all the technical differences.) I don't know the statistics when comparing the average number of photo lens buyers versus cine lens buyers but it wouldn't surprise me if the ratio was something like 10 to 1, photo to cine. This all affects every aspect of lens making all the way back to the R&D and engineering costs, even if you are essentially just rehousing an already existing photo lens in the first place.

I found this video to be clear, concise and very informative - thanks👍

Thank you, glad you enjoyed it 😊

Great video thank you! Would the focus throw of the lenses also be a consideration? Most cine lenses I have seen have long focus throws which I presume is for more control and precision. Whereas many stills lenses have quite short focus throws comparatively. I'm not sure if this is a universal truth but perhaps another consideration

[@DaveMcKeegan]

Some cine versions do receive modified focus mechanisms with longer throws, although in the case of this particular lens they both have the same 270* throw (which granted is pretty long for a still lens)

Hi Dave, first time viewing your channel and just want to say thanks for clearing up some confusion for me. I'm a not very experienced KZbinr/photographer and have been learning as I go with a few GoPros, a DJI Mavic drone, and a Sony RX 100 MK4 point and shoot, bought specifically because it can shoot 4K video. I went to the Sony from a Canon for that reason as well, though I did find that the Canon user controls were much more intuitively laid out. Been saving for an A7 lll for a bit now, and wondering about lenses, so thank you for clearing some things up for me. This might sound like a dumb question, but can I shoot stills with a Cine lens? I'm going to be doing a lot of traveling in the next year, so minimizing how many I carry is important. Thanks in advance. Subbed.

Welcome to the channel, glad you enjoyed it Yes you can shoot stills with a cine lens but there is no advantage to doing so, so unless you specifically need cine lenses for a lot of video work and just occasional photos then I would suggest sticking with still lenses and using those for your video work
