FOV is changing, not focal length. You can't change lens' optics by cropping.

FOV = 2 arctan 18 mm / (focal length * crop factor)

And if you're asking about an object for a given distance in regard of focal length you have to include object dimensions into calculation:

Object width/Distance = 36 mm / (focal length * crop factor)

Disclaimer: Calculations are exact for focus distance = infinity only. Standard lenses do change focal length if focus distance is shorter.

Crop, it means that just a portion of senzor is used, but the optics and dof remain the same. In crop mode you will see just the had of the "dog", but is the same had, of the whole "dog" this time, you see when shoot full frame of your camera.

I'm hoping that someone can tell me whether there is a way that I can use my Canon EOS 50D as a USB connected webcam or use it for HDMI video output (preferably) I don't really need it to record video in the camera. I need to do this with a Windows 10 machine. I see that you can use Camera Live and Cam Twist to do this, but Cam Twist will only run on a Mac. Can Magic Lantern do this, or is it only for recording video within the camera? The Canon EOS 50D does have hdmi output, but this is apparently only for playback and not continuous video. Thanks in advance.

You can use EOS Webcam Utility via USB or any HDMI capture device in liveview mode.

Is my battery for 50D is weak, or is it true that 50D dries out the fully loaded battery very quickly (3 or 5 seconds) when shooting video?

And how can I change the shutter angle? I can't do it.

Walter Schulz · « **Reply #780 on:** May 24, 2020, 10:42:01 PM »

You can't drain a fully loaded battery in 5 seconds.
1.390 Ah -> 1.390 A for 1 h -> 720 x 1.390 A in 5 seconds? No way!

Wlad81 · « **Reply #781 on:** May 24, 2020, 10:48:27 PM »

Does this mean that the battery is just weak?

And what about the shutter angle? I can't change it in LiveView mode. It's always at 330o.

It means it is dead.

There is also an issue with the frame rate of h.264 videos. It's always 30fps, and I cannot change it in either video editor. What am I to do?

reddeercity · « **Reply #784 on:** May 26, 2020, 07:07:27 AM »

go to "Frame Override" Tab and set to "Exact FPS" then dial in the desired frame rate e.g. 23.976 from 30.00 etc. ...
the default Liveview frame rate on the 50D is 30.00fps.

Wlad81 · « **Reply #785 on:** May 26, 2020, 12:11:19 PM »

I can't find "Exact fps" on this tab. I'm using crop_rec-3744x1080_24fps_50D-eXperimental.4.57pm.2020May06.50D109.

reddeercity · « **Reply #786 on:** May 27, 2020, 06:24:25 AM »

You need to enable it with the set button , there's a drop down menu in "Optimize for" etc. ....

Also enable Expo. Override , to get proper shutter angle .

Thanks a lot, everything works now!

It's a pity that I don't have VAF-50D filter for now. I've made tests with raw today, just color graded in MLV App, please, look at it. Added some sharpness (50), clarity, vibrance, saturation (20), filter "Film E100" (50). Shot in 1568x882 10bit, as I have only Transcend 32 GB 133x CF now. Upscaled to 1920x1080. Lens are Canon EF-S 18-55 IS STM. Sorry, no tripod here. What is your opinion on aliasing, is it quite heavy?

There are other tests, with flowers, and there is no visible aliasing.

By the way, crop_rec doesn't work, all the camera shows in this mode is the stripes. What am I to do?

Also, the overexposed areas becomes pink, and I don't know how to grade it. Set the Raw White Level to 200-250 less, set the Highlight Reconstruction and Cyan Highlight Fix, nothing helps too much. Maybe the 12 and 14 bit modes would help?

Thanks to the team for this brilliant hack. Respect.

My 50D is not doing well with ML. It is at best erratic.

There seems to be nothing wrong with my settings. One day it is fine but another day the screen flickers like crazy while recording.
I am not yet sure how to set the ISO and shutter speed settings--I suspect the Canon and ML are conflicting somewhere. The ISO should be controllable via the scroll wheel at the top, right? The ML screen info belies the Canon values.

The camera has frozen so many times while recording.

I use a 32GB San Disk 120MB/s card.

Settings:
Movie record 1920x1080 (trying to match ML RAW values--doesn't work )
ML RAW On, 1568x882
FPS override 24 fps
Actual FPS 24
Optimize for Exact FPS
HDR Video Off (is this what it should be?)
ISO 380
Shutter 1/48.29, 179 deg

And now in Debug it says Memory Error
Thanks!

Hello all, I have a 50d and would loke some direction for getting a good stable(ish) installation. The newest version that I can find is a nightly build in 2018. I have some knowledge of building and developing Windows programs, but not anything like this. Can someone point me in the right direction to get started?

Thank you

randomGuy.

Hi i wonder if I should buy a canon 50 d or a 100d ? which one has better image quality via magic lantern ?

Walter Schulz · « **Reply #792 on:** April 12, 2022, 11:07:51 AM »

Get a 650D/700D/EOS M if you want an APS-C camera with decent image quality/resolution.

shankar101 · « **Reply #793 on:** April 12, 2022, 11:26:27 AM »

All I want is good 1080 p image with great canon colors. I am in love with colors of 50 d . I dont like colors from t series and even eos m at all. 100 d is decent as well but not crisp as 50 d so I wanted to choose between two . what do you suggest me ? i have very less budget

Walter Schulz · « **Reply #794 on:** April 12, 2022, 11:50:04 AM »

? 100D, 650D, 700D, EOS M share the same sensor and internal processor unit (Digic 5).
By "1080p" you mean Canon's native video service (H.264, MOV)? There is no IQ improvement by ML for this mode.

shankar101 · « **Reply #795 on:** April 12, 2022, 12:49:01 PM »

does scandisk extreme pro 95mb/sec 32 gb card work with canon 50 d ?

Walter Schulz · « **Reply #796 on:** April 12, 2022, 12:58:10 PM »

No. Because 50D has a CF-card slot.

shankar101 · « **Reply #797 on:** April 22, 2022, 10:23:58 AM »

what is the highest quality and stable cf card i can get for 50d?

Walter Schulz · « **Reply #798 on:** April 22, 2022, 11:04:49 AM »

Sandisk Extreme Pro

If you want to use full sensor area, this camera is limited to 1568 pixels wide which is not exactly full-hd 1920... Of course if you are not using crop mode.. and in crop mode you will be using VERY tiny sensor area, so you need really wide angle lenses.
I think this is very limiting. And CF card can be more expensive than the camera itself

And colors.. I don't think you get "Canon" colors in mlv raw, it's all in your hands though. Raw is terrible when you first open it in MLV App for example, but it is RAW so you can do any corrections and basically make colors look exactly as you want.
Is mlv's from 50D looks really better than from EOS M for example? Maybe you just like particular color grading from someone, and not the camera colors itself?
