    Few things:
    1. Full frame DOF, compression, transition between focus and out of focus are and overall light gathering capabilities is not “made up” - it’s as real as the earth is round. Maybe worth getting an equivalent camera like a Monstro and do some side by side testing before saying stuff online thats not true.
    2. Speedboosters WILL increase more chromatic aberration.
    In my experience if you want none or as leas as possible look at lenses with APO designation (they all fairly modern though).

    • @WhomAmI
      @WhomAmI Год назад +3

      I think he means the general belief that full frame = shallower DoF rather than full frames allows the extra room to achieve a shallower DoF. Which he's right, it's a misunderstanding for the sake of layman.

      @darthvini Год назад

      You are right, any Speedbooster will increase Chromatic aberration. Mainly for 2 reasons: 1 - You are seeing the whole image projected by the lens, therefore any prismatic effect will be shown by your sensor. 2 - The speedbooster glass itself can produce its own C. A. once it can´t be thick enough to prevent it due to limited space it has between the back of the lens anthe camera.

    • @flyingfox2005
      @flyingfox2005 15 часов назад

      Compression is simply a product of distances between lens entrance pupil to subject and subject to background... nothing to do with sensor format or lens.
      So a 50mm lens on FF/135 has the same "compression" as a 35mm on S35 - assuming the camera positions are fixed. In the same way a 35mm on S35 has the same perspective distortion as a 50mm on FF/135 - as that too is simply a product of distance.
      If you are using a focal reducer you are of course gaining a stop of exposure - so a 50mm T2.8 lens on S35 with a 0.71 is giving you a 35mm T2 lens.
      A simple way to show that FF/135 doesn't gather more light than S35 is to shoot a FF/135 camera with a S35 mode. Keep the same lens on the camera, shoot one image in the FF/135 mode and one in the S35 mode. Exposure is THE SAME.

    The Milvus 50mm f1.4 is one of the best lenses I have ever shot on. It's unbelievably sharp wide open and only gets better stepped down. Between the image and build quality, it's easily one of my favorite lenses of all time. Interested to hear your thoughts.

      filmmakers and director of photography pick certain cine lenses due to their flare, their characteristics, and their look, and they try to find the best lense that fits the mood of the story, they donot have a perfect standard for lense, just based on the emotion and feeling. Thus this video only makes sense if you are not thinking as a true filmmaker

    Hi Spencer. I know you stopped using diffusion filters in front of your lens (a la Deakins) but I found that even a light filter like the Black Pro Mist 1/8 can help "hide" some chromatic aberration. I recently used one to hide Zeiss CP2 CA, a lens that are pretty sharp and still show some quite pronounced CA. Test it out and tell us what you think! All the best

    Hi Spenser,
    I got the cine kit Mitakons T1 for MFT they are great pair with BMPCC4K...and when shooting GH5,6 the image is less digital.
    They are pretty fairly matched and one of the best prosummer Cine Lens for MFT and 4 lens for around 1100$ is a good deal..but I definitely like more shooting with S5 and prores RAW just more control
    About CA a lot of things can be fixed in Resolve even a person like myself so a not trained colorist can do it with some work around...if you still have the S5 or even better S5ii around you should try the Panasonic lens S prime line they are kind of very neutral imho but have more character VS sigma 18-35 and are very good matched and with linear focus in option for manual focusing still focus by wire but with greater control.
    And I agree with you lens are very important...
    Nice video and work

    Hey, I think there might be a mistake in there w.r.t. bokeh and speed booster interaction (or, of course, I'm wrong).
    You mention at 10:15 that the speedbooster increases the size of the bokeh balls due to changing the T-stop, which afaik is not true - the bokeh is unaffected by the speedbooster (unless ya meant bokeh can be affected by change in position due to change in fov due to speedbooster).
    To see this for Yourself, You can take a full frame camera and take a test shot, then put a speedbooster onto the lens and use s35 mode. The second test image will be brighter, but won't have larger bokeh.
    One way to visualize this is: there is a certain image that is coming out of the back element. This image determines the size of the bokeh, and basically all image characteristics, really. All the speedbooster does is shrink it down, making it brighter, but not changing anything else.
    Another way to frame this is that while the lens + speedbooster combo is faster, the combo is in effect also a wider lens, so increase in bokeh due to T-stop change is cancelled by the larger FoV (though this framing device is less accurate than the first one imo).
    Here's a handy reference with some tests: ruclips.net/video/xlnciK2cyto/видео.html

    • @spensersakurai
      @spensersakurai  Год назад

      the speedbooster is basically a magnifying glass. it just makes the apparent size of the bokeh larger but in doing so adds a stop of light. so i didnt explain that super clear off hand when talking but i bet people get the idea.

    Great video! Please do a whole video on S35 vs. Full Frame! Also, could you test out the Zeiss ZF/ZE lenses, now known as the classics? These were before the Milvus, but I still use a complete set, and to me, they are one of the best non-cinema lenses I've ever used. Thanks!

  • @KenFlanagan
    @KenFlanagan Год назад +3

    Milvus?? I have them and I don’t feel that they give anything special. Otus maybe. I also have the fd Leica Zeiss and mamiya in a search for something inspiring and whether it’s the sensor or the lens imo micro contrast is really what we should be looking for if we are filming faces in particular and whenever we want that wow image that just has an effortless quality and fidelity. Likewise I have the sigma art series and vespids and most of the time most jobs don’t need anything better. The sigma cine lenses are nice but nothing special. Absolutely agree that any lens worth sticking on your camera has to be significantly better than the 18-35mm. Using a low con filter is also pretty essential if there js a high contrast image. Low contrast lens are absolutely essential but ones that do not sacrifice micro contrast and fringing is always ugly. Most modern budget lenses are functionally excellent and as explained so many dps just want the image clean so that post can do what they do later. Apo lenses are a good starting point and the dulens lenses have something special when it come to clean and affordable. Modern Leica summilux c lenses have something special whilst being super clean if you are renting. I remember trying some rehoused reworked super baltars and was blown away. They can be great in an entirely different way if the sensor is a little too digital and you want a little cinematic magic. At a certain point just hire the best lenses you can if you have a budget if it’s not a job and it’s for fun or social media then I doubt anyone will care or be able to tell the difference. But they will notice soft out of focus images and unwanted artefacts like fringing. Imo I have always gone with Zeiss super speeds whenever I have had the chance but I’m more tempted to try the tribe 7 blackwing 7 to see what all the fuss is about. So many amazing lenses out there. Imo in terms of vintage lenses that are cheap the mamiya sekkor c have the nicest look though a set is almost impossible and it needs an adapter but it’ll make faces so three dimensional in the right hands. Thanks so much for the video and thoughts.

    Probably mentioned by other commenters, but speed boosters don’t alter depth of field. You’re just getting more real estate which gives you extra light which is why people talk about climbing t-stops. It doesn’t affect depth of field, so the premise of the video is pretty much undermined.

    • @flyingfox2005
      @flyingfox2005 15 часов назад

      A focal reducer makes the lens wider - so a 50mm becomes a 35mm - and you gain a stop - so a lens goes from being a T2.8 to a T2
      The Tstop changes because the fstop changes.
      Fstop is focal length divided by diameter of maximum aperture. Since the focal length has changed and the diameter of the max aperture hasn't - fstop has to change. The fstop changes... so does the Tstop.
      The depth of field doesn't change because you have created a focal length equivalent - so a lens which on S35 will match AOV of depth of field... because the lens is now wider (35mm) and a stop faster.

    I love using my 18-35. I am very curious about 40mm lenses lately. I'm trying to decide between the 40mm Sigma Art and the DZO Vespid 40mm. The Sigma seems to be the sharpest Art lens according to what people say about it and has a good focus throw of 128°. It is quite heavy though. The DZO has a very nice cine build quality, an even longer focus throw of 230° (is that too long to pull without a FF?) and seems to be reasonably sharp. The DZO has more glare and generally seems to be a bit more of a dirty lens. Now the DZO is more than twice the cost, less sharp, less clean and still the Vespid has some appeal because of the lovely cine build. What are your thoughts? Have you worked with 40mm lenses? Do you like that focal length?

    I'm still deciding between Meike and Irix and I can't decide..
    but what struck me in your video and even you are mention it too, was some kind of glitch movement due to focusing , almost only with IRIX lenses even with or without speedbooster.
    What was cause of these glitches? You mention your mount, but why was this doing only with Irix lenses? Do you use any adapter with irix lenses? For me it was quite strange to see on the lenses in those price points. Your camera mount was somehow untightened or? What do you think was the cause of that problem when your follow focus literally move with whole lens/camera?
