    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.

    • @frankhu8692
      @frankhu8692 ปีที่แล้ว +4

      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

    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: th-cam.com/video/xlnciK2cyto/w-d-xo.html

      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.

    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

You just need a micro screw driver to loosen the set screw on the side of the adapter, rotate the element to slide it back.

    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...

    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.

    Hi, I'm a writer/producer working on my own movie. I'm in the planning production stage and I'm thinking about how I want the film to look. I saw Stuart Dryburgh's cinematography on the film, The secret life of Walter Mitty, and I loved how the film looked. I know he used Hawk V-Lite anamorphic lens to shoot the movie but I wanted to know what else he did to get the look of the film. How did he get that texture to the scenes. The movie looks a little fuzzy and warmer than other films

    Hello Spenser,
    first I wanna say you did great work and your channel is very helpful with lot of info about lenses. I subscribe immediately.
    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?
    Thank you for your work and answers!

    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?

    Youre confusing the shit out of me man, i think youre calculating S35 aperture equivalence wrong. Meike T2.1 on a Komodo, for example, is roughly T2.8 without focal reducer. The Komodo crop factor is 1.3, so 1.3*2.1 is 2.73, or basically 2.8. A focal reducer on a S35 sensor is meant to return it to the marking on the lens, to make the focal length and aperture closer to full frame and meagting the crop factor. It doesnt boost the aperture to beyond what rhe lens is designed for anymore than it boosts the focal length wider than it is designed for.

    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.

      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.
