    Is the EOS-M *THE* Digital Super-8 Camera?

    I’ve been messing once again with using my EOSM as a Digital Super 8 camera and I’m pretty happy with the results. 

    For the video below I used the following setup.

    6mm f/1.2 Pentax TV lens (paper shim between lens and C mount-EOSM adapter, for infinity focus)
    Tiffen Digital Diffusion 5 filter (reduces moire artefacts)
    EOSM with latest ML build
    18fps override (exact)
    5x zoom
    12bit lossless RAW
    4:3 aspect
    1440 x 1080 

    i just used the aperture ring for exposure, rather than ND, as it seemed more authentically consumer Super 8.

    This video has effects applied - FilmConvert’s Super 8 grain; FCPX native “aged film” effect applied very sparingly for jitter and a little dust; a telecine’d Super 8 black frame (keyed over footage). If there is interest, I can post the ungraded footage.
     

    may I know how much of spacer shim did you add to adjust for infinity focus?

    Here's the footage I shot (and threw a load of film emulation effects on top of). It's not edited into anything interesting it's just 20min of stuff ... so skim through and find the bits you like.

    Some other nice stuff posted here folks - nice to see! The main tips I'd give are:

    1. Be aware of the horrific aliasing - tree branches against a bright sky look just horrific. I've added a strongwomen Tiffen Digital Diffusion or HDTVFX filter to the front of the already soft 6mm lens, which suits the consumer 8mm look I'm going for and deals with most of the aliasing. Adding grain in post helps diffuse it too.

    2. Rolling shutter. It's awful. Put the strap on the camera and pull it taught around your neck (or use a loupe) to avoid jitters. A pistol grip handle helps too as the EOSM is not an easy camera to hold steady. Then stabilise the footage and correct the rolling shutter in post as best you can (I use Lock & Load).

    Here's the vid. I'm pretty pleased with it as a Super 8 simulation.

    Pw: S8mm

     

     

    It is very lovely and the image is convincingly natural.
    I thought aliasing on the eos m only exist on line skipping video? 

    Wondered about the use of variable nd on cctv lens (especially the pentax 6mm f1.2), does the whole element spin during focus?
    The footage is really nice and I can't see the effects of rolling shutter.

    Does the EOS-M have HDMI out to view?

    yes, and it is a full hdmi out lol, it however, when connected, will disable the screen on the eos m 
    the hdmi out displays ML menus too.

    The best bang for the buck of the camera history... ; -)

     

    superb!

    This thread is fascinating.

    If anyone is running a recent version of the hack, what is the state of live view when recording while cropped in 3x (for C-mount lens shooting)? Is it smooth, or choppy? If it's choppy, can live view be improved by shooting without raw, but rather than high-bitrate hack (if capturing the 3x crop is even available in that mode)?

    I am currently weighing the pros and cons of picking up an EOS-M (shoot in 3x crop mode with ML), an M50 (cropped 4K + 1080P crop), or a Pentax Q (probably not) for playing around with some old 16mm film lenses. Just making sure that I have all the facts.

    I am happily using eos m with ML and a c mount lens ( originally for super 8 ), with RAW rercording in 4:3 ratio, 18fps, the live view works great with the correct ratio, frame rate. So it should work fine with 3x crop. 

    Only the 4k/2.5k seems to have unusable liveview for me.

    by the way, how did you get 1440 x 1080 resolution?
    as there is only 1280x960 4:3 or 1600x1032 in 4:3 aspect but it actually is 1.55:1

    sorry im a bit confused

    @tupp @youshouldtry11  thanks for this, had never heard of the cameflex mount!

    Shooting in raw is stable even with the SD overclock hack - I rarely had problems with corrupt footage, unless it's an extremely experimental build. The only issue with the SD hack is activating it, which can be a bit risky, but after activation, the camera is fine to use as normal.

    If you want to avoid the SD card hack and want to use s8 or s16 lenses, just download the latest 4k lossless experimental build from the magic lantern website, select "movie crop mode" in 10 or 12 bit lossless raw up to 1800x1030 resolution (4.66x crop). That mode is nice to use as it gives you a properly framed liveview, and should give you fairly continuous recording times.  Of course you can also select lower resolutions whilst in movie crop mode if you want a bigger crop or a different aspect ratio. 

     

    The lens finally came by, doesnt seems to be parfocal (adapter seems great), but there is a knob behind the aperture ring where you can adjust the glass elements... Tried different positions but it just doesnt seems to work as a parfocal ...

    Sounds great! Will definitly try it!

    However, i do want to mention that movie crop mode has to be activated everytime upon turning the camera on... 

    Does anyonw know the fix to this?

    @youshouldtry11 The lens is pretty small, but heavy as it's metal - feels front heavy on the eos m. It's a c-mount lens -I think this is the adapter that works best to make it work parfocally, though haven't personally tried it: https://fotodioxpro.com/products/c-eosm   

    Don't know what mount the lens in your photo has - it doesn't look like it has any mount at all, maybe it was unscrewed or removed, or it's a custom built one?

    can you take a photo of your lens back? I want to compare it
    ....

    isn't this a c mount?

    @youshouldtry11 if you plan to use super 8 lenses, you're best off using "movie crop mode" and cropping to 4:3 aspect ratio in post to get rid of most of the vignetting. Movie crop mode in h.264 (1920x1080 resolution) is similar or same to the field of view you get with movie crop mode in raw (1080x1030 resolution). This is a 4.66x crop from full frame - which is larger than super 8, but cropping to 4:3 aspect ratio will get rid of most of the vignetting.  Below are tests I did with the eos m and schneider 6-66mm f1.8 which I had posted here a few pages back. I shot this in raw at 1800x1024 in movie crop mode. 

    For this lens I think the fotodiox adapter is the best one that will give you parfocal lens performance, from what I heard. It's tough to find an adapter that works as they all seem to be really different.

    If you want to use super 16mm lenses and shoot raw, there's also the option of using 5x zoom mode with a max stable resolution of 2520x1080 (3.33x crop from full frame), this is close to 16mm (rather than s16). However, it isn't possible to shoot this resolution with regular h.264 video.

    Thanks for a swift reply!
    So helpful and such a nice video with the synth music.
    Can you tell me about the handling and experience with the lens? i.e. is it extremely big and bulky?
    What mount is it? did you said it was a leica R mount?

    And will the back part of the lens make it unusable?


    thanks again!!!

    It just seems impossible to mount.... isn't it?

    Thanks for everyone's useful information and sharing.

    I am looking to purchase a second-hand EOS M as a digital super8 that shoot vintage-looking footage (I can't afford shooting films!)
    I want to shoot in a maximum bitrate as possible and doesn't mind a 3x/5x crop/even in 720p as can use super8/super16 lenses for it
    (I won't shoot RAW video as it seems relatively unstable)

    However, I don't understand what exactly is the crop for the current ML update for EOS M max bitrate video recording, can someone please help?
    therefore I am struggling to choose a lens for this setup. I really wanted a vintage looking, manual zoom lens that is parfocal and relatively fast and can be mounted on the Eos M.
    Considering to mimic the super 8 film look, I am not looking for crazy reach or superior sharpness.

    @cantsin's Schneider Variogon 6-66mm/f1.8 Leica M mount lens  & C mount Angenieux 8-64mm/f1.9 seems to be a great fit but I can't seems to find it, 
    and I am not sure if the newer version ML can still shoot in the 5x crop with maximum bitrate/significant crop.

    Can someone using ML please tell me the crop in video and recommend some lens for me?
    are super 8/ super 16 lens good for the crop of ML new update?
    I am currently considering these lenses but I am not sure if it can be mounted/ the image circle can be used without a significant crop in post.

    SCHNEIDER-KREUZNACH VARIOGON 7.5 - 37.5mm F1.8 CINE ZOOM LENS

    Pentax TV Zoom Lens 8-48mm 1:1.0 Auto-Iris TV Lens - C Mount

    Schneider-Kreuznach Variogon 1.8/9-30mm

    Schneider Objektiv Optivaron 6-66 Macro 1:1,8 Filmkamera 8mm


    Please correct me if I am wrong and I appreciate everybody's help and opinion!!! ❤️
    Thanks for everyone reading this!!!

    Thanks @tupp. I guess this update makes the title of this thread slightly out of date now!

    Here's the build I used: https://bitbucket.org/Dannephoto/magic-lantern/downloads/magiclantern-Nightly.2018Jul03.EOSM202_mv1080p.zip   With this build you're stuck with shooting full sensor only (3x3 pixel binning), you can't switch to 5x zoom mode. They may have partially fixed that in the newest build but unsure if you can then access the full sensor height, I'll need to test. See here: https://www.magiclantern.fm/forum/index.php?topic=19300.msg204564#msg204564  

    I shot that footage at iso 100 and iso 400, f3.5 and above. I later noticed that if I export to prores on MLVapp I get less noise in the shadows that exporting to cdng (which can look really excessive if you push up the shadows). However I don't know if I tested this fairly and will have to experiment further. The above video is cdng.

    Right now the main issue is liveview preview is streched vertically 1.6x (preview looks like you have an anamorphic lens attached) and you can only see the top half of the image. It's still usable though and half-pressing the shutter gives you a low fps / pixelated preview of the whole frame.

    The moire/aliaising can get fairly bad depending on what you're filming, and can become very obvious if cropping in on an image. I guess it's now the same amount as you get with all the other aps-c Canon DSLRs, or it's similar to the bmpcc. Exporting to prores rather than cdng on mlvapp can sometimes reduce the amount of moire - I need to test this further though.
