"I have disabled highlight tone priority, it has extended the ISO range down to 100, but every photo still comes out over exposed. Only with auto ISO does it look right."

I experience this with a few lenses when taking pictures, notably my Rollei HFT 50mm f/1.8 and SMC Takumar 200mm f/4. Using the exposure compensation to make the camera "underexpose" half a stop or so sorts this out. Other lenses don't have this problem at all.

Danne

There are some settings like you mention that will interfere with exposure using manual lenses etc. I'm sure you'll pass them all in no time.

Have fun :)

Thank you for the link😍

I hope the exposure preview will be correct once I use chipped m42 adapter + ef adapter (when that comes). I get accurate exposure when shooting stills in video mode, so I will use that for now.

Hm... never had much overexposed photos with the M. Did you use Av mode for your manual lenses? My PB-EOS adapter has no chip and it works wonderful.

I used manual M mode and manual ISO, only auto ISO gave results that match display exposure, when using manual ISO the result is about two stops brighter than it showed on the screen. The adapter I am using right now is an M39-EFM - no chip at all.

Danne

Test enabling or disabling exposure stuff. There are two places I think. Exposure should match. Get a screen shot from masc camera settings ;)

I will try and find all exposure settings I can. Menu is unfamiliar and a little bit intimidating. So far I only disabled highlight tone priority in custom function (what a weird place for the setting, and strange that it is enabled by defualt)

I disabled all exposure related stuff in canon custom functions, video and photo modes have diffferent brightness even on manual and same settings, but when taking picture its good exposure (like liveview in videomode) but in photomode liveview is too dark, whjich is strange cause its full manual same iso as video mode and same shutter, same aperture, so in the end it does take picture correctly but liveview brightness is not correct when in photo mode.
Auto iso doesnt help , it actually makes things even more incorrect, liveview is still too dark in photo mode and autoiso.
taking picture when touching screen is not helpful at all, cant get into magic lantern menu with 2 fingers tap.
OK, managed to get into ML menu in photo mode, disabled ExpSim in expo panel  and then enabled ExpoOverride which is important and it fixed wrong screen brightness.IMo it should be disabled from get go and set like that.
ISO up/down buttons dont work for me in photo mode( they bring up typical shooting mode selection), too bad cause its very useful.If some people dont like it , it still would be great as an option, in ML menu photo mode ISO up/down is still enabled like in video mode but it doesnt work.

Sounds just like the issue I am having!

But I don't have the issue when I tried my 19-35 electronic lens. Only with manual lenses.

Danne

That's what happens when switching to manual lenses. Try 2blackbar suggestion.

ilia3101

Oh wow enabling expo override and disabling expsim does fix it! Magic Lantern fixes the EOS M's broken ness.

Thanks so much.

May I ask how I can take a picture in Manual Focus mode
with a manual lenses? The Canon EOS-M wont take a picture unless Its in auto-focus mode
with an auto-focus lenses. The Firmware 2.0.2 and 2.0.3 wont allow it but the previous
old firmwares will but they're difficult to find.

Anyone know of a fix?

lightspeed

with 10 bit the signal is divided by 32 before compression. anyone know why that is the case?

DudeSoCool

CAN anyone show me a way to get Canon EOS-M to take a picture in manual mode on the firmare 2.0.2. or 2.0.3 despite the fact it only has autofocus and only takes a picture with autofocus and autofocus lenses?
IM using Manual Focus lenses and I want to take a pic!!!!

@Danne

I own 2 eos M and I am very happy with what you have done on magic lantern for them. I now own also an EOS 650D, do you think it is possible to have the same things in ML for the 650D, like touching the screen to directly access the setup for MCM rewire and other setup without dealing with to much setup in other ML tab. Thank you for your icredible talent.

DudeSC theres this dumbest useless canon setting in menu that blocks taking pics with manual lenses, its in canon menu just disable it.release shutter with manual.lens or soemthing like that , im away from cam dont remember but its enabled by default.

ZEEK

Yep. It's in the "yellow wrench" settings under "Custom Function" - Enable "release without shutter" or something like that...  8)

where can I find the canon menu to: enable AWB and to set audio levels?

turnlemons2lemonade

Jut press the menu twice to go in the Canon menu and you can find both.

Congrats Ilia on the purchase!  8)
Thanks to Danne & the ML Team, 5K rewired is awesome! 10-bit is the best if you want continuous recording using that mode with Ratio "on" @1464x1836, 23.972fps [2.39:1 or other] or ratio off @1736x2178, 18fps, 2.39:1 or other]. You can select 14 bit but you won't get as much recording time unless you dial the resolution back. Its also nice to have a full frame dslr and mirroless camera, good combo! I know MSAC also has these two which is cool!

@Danne
With ratio set to OFF in 5K Rewired @1736x2178 I can get 23.97fps using fps override, the only issue though is that it freezes in the live view.  ::) :'(

With 5K rewired and ratio OFF I get 12fps. And when I try to fps override above 15fps, the image just stops existing and I get 2.6 kilobyte MLV files. How can you get 23.976 @ 1736x2178??? I literally cannot make it work much above 12 fps

Also how do you set ISO while in video mode?

Danne

Iso through info screen but really. Use up or down press for fast iso access. Works even while recording. You can turn off this iso feature if you want to use ml iso or default.
24 fps with full readout sensor is not possible.

ilia3101

Thank you Danne! I like the ISO with buttons method, much faster than normal version.

I figured out that I need to enable "set 25fps" - then I get 1736x2178 at 18fps - without enabling it I only got 12. The name of the option doesn't make much sense, doesn't seem to do anything related to 25 fps :D But 18 FPS is good enough for me.

Danne

Yes, got the question about 18fps a while ago but couldnĀ“t find a real logical way to add it so I just enabled this mode with ratios off ans set25fps. Good you found it :).

ZEEK

Glad to hear it's working! 8) 5K Rewired Mode is really nice. I have to say 2.5K is really amazing also. The resolution and detail you get is really noticeable and especially when you upscale it a little, looks tremendous. I don't mind the crop factor. it behaves now like the Original BMPCC with the crop factor (around ~2.9x) and works well if you have wide-angle lenses. Thanks Guys! ;D
