No lens will look as good as with MLRaw ;) . My Canon FDs look good on GH5, but they look amazing with MLRaw.

Maybe these older lenses just look nicer when you have a fuller colour spectrum, having 8-bit you loose a lot of that at which point you probably only focus on their short comings as vintage lenses (or at least rank them more in the sharpness/distortion category).

I think film is a lot like audio, where everything in the signal path just makes things worse, and the high quality stuff still makes things worse, but only by a little bit.

I think all the nice lenses must be at least 16-bit ???

Latest EOS M ML RAW builds are from master chef Danne, here: 

And you can follow development on the same thread.
MLV App is de facto the only application to use as starting point of your editing.
It is as an extension of the EOS M ML RAW video for many reasons:
    - effective way to remove focusing pixels
    - correctly debayering 5K Anamorphic crop mode. Or pseudo anamorphic is reality but anyway

And yes get the latest MLV App and EOS M RAW versions. Ilya keeps adding new features to MLV App and Danne keeps fixing bugs and improving the build.

To prove resolution is and is not anything to be focus about, just a tool as many other variables no less crucial:

From YT page:

<< Footage shot with the Canon EOSM in early March 2019. First of three videos - this one uses the Pentax SMC 50mm f1.7 lens. Used Image Stabilisation in post - I prefer not to as it gives some of the footage that usual warbling effect, but it gets pretty windy on exposed mountain sides and this is nicer than shaky footage. IS lens on the way soon! mv 1080p MCM rewire 16:9 Ratio Recorded 1736 x 976 Upscaled in MLV app to 1920 x 1080 Rendered and uploaded in 4K 14 bit Lossless 24 fps Variable ND Filter Standard EF - EOSM Mount Adapter (Non-Speedboosted) Cinematic LUT applied along with grading in Final Cut. >>

According to the technical info:

<<The clips were recorded at 1488x1900 pixels and were resized to 4464x1900 using lanczos algorithm. Grading is done in MLVApp only. No LUT was used. Gear: Canon EOS M Viltrox Speedbooster EF 16-35mm 2.8 USM L II Variable ND filter Cullmann Nanomax 290 Monopod>>

Here's another 5K anamorphic mode test from one of Danne's builds:

Impressive definition from such hack UHD trick...

Metabones announced a new Speed Booster (EF to EF-M mount). Metabones EF-EOS M Speed Booster ULTRA 0.71x is available right now for $479.

Press release:

Metabones® Introduces EF to EOS M (EF-EFM Mount) Speed Booster® ULTRA 0.71x

Vancouver, Canada, May 2, 2019 – Metabones introduces the latest member of its award-winning Speed Booster family of DSLR (digital single-lens reflex) to mirrorless lens mount adapters, EF-EOS M Speed Booster ULTRA 0.71x. Full-frame Canon EF-mount lenses are now one stop faster, 0.71x wider and with increased MFT (note 1) on Canon EOS M cameras. The 4k/UHD video crop on EOS M50 can also be mitigated with third-party APS-C lenses using this Metabones Speed Booster. Some Canon EF-S lenses may be modified to fit on the Speed Booster but Metabones cannot be held liable for any issues arising from modifications. Using APS-C lenses with Speed Booster for still photography or full HD videography may result in vignetting.

Ever since the first Speed Booster was introduced, there have been DIY attempts to modify it to fit EOS M cameras. The turnkey solution Metabones now offers adds a number of refinements:

The optical housing is redesigned for a perfect fit on EOS M.

The EXIF metadata is changed to reflect the faster aperture (note 2) and shorter focal length.

 The autofocus speed of the lens is adjusted and optimized for the change in focal length and aperture to ensure the best performance. This is especially important for dual-pixel autofocus (DPAF) in video mode.

A ‘chip’ mode is added so that the user may store the metadata of a fully mechanical manual lens in the adapter.

A LED indicates the operational status of the Speed Booster.

Since both the lens and the camera speak the same protocol most features are supported with the exception of lens aberration correction, which is automatically turned off.

Speed Booster ULTRA

Speed Booster ULTRA uses an advanced 5-element/4-group optical design by Caldwell Photographic Inc., incorporating ultra-high index tantalum-based optical glass to achieve extraordinary optical performance with improved corner sharpness, distortion and reduced vignetting. Speed Booster ULTRA has a magnification of 0.71x, effectively reducing the crop factor of APS-C cameras from 1.5x to 1.07x. The Speed Booster ULTRA design makes very effective use of exotic materials at the furthest limit of glassmaking technology, and as a result, is well corrected for use with virtually all full-frame SLR lenses regardless of exit pupil distance. Thus, the Speed Booster ULTRA performs extremely well with professional-grade f/2.8 zoom lenses such as the 24-70mm f/2.8 and 70-200mm f/2.8 zooms by Canon to produce 17-50mm f/2.0 and 50-142mm f/2.0 high-speed zooms, respectively. Similarly, high-speed fixed focal length lenses such as a 50mm f/1.2 will be transformed into a 35.5mm f/0.9 lens with excellent contrast and resolution from the center all the way to the edges of the image.


Metabones EF-EOS M Speed Booster ULTRA 0.71x is available right now for USD 479.00 plus applicable taxes, duties, and shipping, from Metabones’ web store and its worldwide network of resellers.

Note 1: compared to the same lens on the same camera with an ordinary lens mount adapter without optics.

Note 2: to ensure compatibility with hardware and software, which do not always handle sub-1.0 apertures properly, f/1.2 lenses will display their pre-boost aperture. Please rest assured that the display has no impact on the actual maximum aperture and a maximum output of f/0.9 is supported.

Perhaps a silly question from an about-to-be first time ML user: does the EOS M autofocus work with Magic Lantern?
