Canon EOS M

[loknar]

It took me while to figure out what "the other routine" means 
You were right, with SDR50 it works at 240 MHz @ 73MB/s 
Thank you.

Nice. Good you figured it out. Can't keep track of all terminology all the time  .

Canon 13x zoom, 7.5 - 97.5 mm, f 1.4

I mentioned this lens in a post long, long ago, but I have significantly improved its performance since then, Using the ML 3x crop feature.

Here's a still photo of the lens mounted on the EOS M:



Note the dark grey tube behind lens & camera, it contains the secret of the improvement!

you can try using this https://imgbb.com/ then paste code generated to post, usually I use bbcode full to attach photo

Thanks, ML700D and Walter! I didn't know the correct tag, apparently IMG need to be in captions and/or the /description is necessary? (Me being a geezer noob... )

I have another optical project ongoing, too, a relay-lens system for a "periscope lens" using a 1.7 mm fisheye lens for GoPro-type cameras. Here, too, ML's 3x function enables full-frame video from that tiny lens.

However, it necessitates quite an optical construction, here assembled on a piece of angle iron, working as an "optical bench":





Explanation: Furthest from the camera, at left, is the 1.7 mm fisheye lens, diameter only 22 mm (7/8"), then a 20 mm Bolex 8mm projector lens that focuses the image from the fisheye toward the relay lens, which is from a laser copier. Then follows an objective lens from a small binocular, which collimates the light toward the actual camera lens, which is the rear part of a C-mount video "pinhole" lens. The pink rings are just holders for the components, all turned to 22 mm diameter. The angle iron is attached to the camera lens with masking tape - simple, but workable for this test!

Since all the optical components are achromats, the chromatic aberrations should be minimal. There is quite a bit of spherical aberration, though. I already know that the edge sharpness won't be perfect, but the intended use is for closeups of flowers and insects, still showing a relatively in-focus background. A 1.7 mm lens has an incredible depth-of-field (2" to infinity) even fully open - which in this case is around 5.6 to 8 due to all the optical components.

I'll post a video when I get the project finished - I will yet have to make a system of threaded tubes (total length about 250 mm, 10") in order to do a final assembly - thanks to my hobby lathe, that should not be too difficult a project...

So cool. I want one!

[Janke]

You can buy one - it's "only" US$ 2,299.00 :

Mine will not be as good, but a few f-stops faster, and much wider...  ... and cost me zilch!

Here's the very first movie test on the "optical bench" - mid-take, I'm actually almost touching the lens with my finger:

Hi, I'm new with Canon Eos M and ML. I've installed the latest build.
If I enter the movie mode I cannot see presets, custom modes, ratio, bitdepth...

My menu start with Bit Rate, Rec Key, Gradual exposure etc

I'm sorry if it's a stupid question but
Can you help me, please?
Tnx

[Walter Schulz]

It would really help to put a name and date to "latest" build.
Most likely you haven't installed Danne's custom build for EOS M. Start here: https://www.magiclantern.fm/forum/index.php?topic=25781.0

First test of the above mentioned "periscope lens" installed in aluminum tubes is now on "Share your videos", i.e. here:
