Full-resolution silent pictures (silent.mo)

[josepvm]

During my test yesterday on 500D (nightly 2015 March 29th) expo override worked fine for my STM lenses, as I already posted.

But now I've tested it also on my recently purchased EOS M. And there is really a problem with STM lenses.

Lenses I have tested (EOS-M nightly 2015 April 14th)

- EF-M 18-55mm STM   Expo override does not work, exposure in FRSP does not change at all when changing aperture.
- EF-M 11-22mm STM   Same behaviour, expo override does not work
- EF-M 22mm STM  Exposure in FRSP does not change when going from F2.0 to F11, but there is some degree of exposure reduction at F16 and F22

Using the EF to EF-M adapter on EOS M I get:

 - EF 50mm f1.8 and several EF-S USM lenses: expo override works Ok.
 - EF-S 24mm STM:  same behaviour as EF-M 22mm STM prime, exposure only changes for F16 and F22
 - EF-S 18-55mm STM and EF-S 55-250mm STM: same behaviour as EF-M zooms, expo override not working, exposure does not change at all.

Tonight I will repeat tests on 500D with a more recent nightly.

Yep, confirmed the same behaviour with my own EF-M 18-55mm STM

Tested again on 500D, with nightly 2015 April 19th. Expo override works well with my EF-S STM lenses (18-55mm, 55-250mm and 24mm).

It seems that on the old 500D the STM, USM and micromotor lenses work all in the same way (it makes sense, STM lenses did not exist when 500D was launched). But in newer cameras (optimized for STM lenses, with phase detection AF on the sensor), probably the STM lenses are corntrolled in a different way...

Video related to the aperture problem with STM lens as promised.
Same problems as stated before.

It's funny to see that I'm kind of the first to point out that problem.
I'm glad to see that it wasn't only a mistake from me

Lens tried:

10-18 STM
55-250 STM

I do high magnification stacked macro pictures and am really thrilled by the full res silent function. For high magnification vibration is a big problem and one way to solve it is by using flash. I am planning for a circuit that will let me trigger the silent shooting, wait a defined time and then fire the flash.
I noticed that after taking a picture I need to half press the shutter again. Is there a way around that? To let the camera automatically return to live view after taking the silent picture?

I was told that there is considerable variation in the delay between pressing the shutter and taking the picture from standard live view - at least on the EOS Ti1. Do you know if that is also the case for silent pictures? Has anyone measured the time from the half-press shutter to the clearing of the sensor is done?

Add the 18-135mm STM to this list, I've tested it yesterday on my 70D (firmware 1.1.1B) and it wouldn't work even with Expo Override...

[Licaon_Kter]

It's funny to see that I'm kind of the first to point out that problem.

The slow speed ( max 1/4 ) kinda duped me, a lower aperture was not wanted/needed anyway, hence this got away.

Hi, I have just download Magic lantern (•magiclantern-Nightly.2015Apr28.5D2212.zip
•Built on: 2015-04-28 00:10:02 +0200) to test full resolution on silent mode and after successfull installation, I have followed this steps I found in this fórum on my camera 5d mark II

1.) Prefs tab -> Config files -> Restore ML default
2.) Restart cam
3.) Activate Silent.mo
4.) Restart cam
5.) Put cam to M mode
6.) Activate FRSP (Shoot tab -> Silent Picture -> Silent Mode -> Full-res)
7.) Activate Liveview
8.) Press shutter half

But I do not get anything. There is a message in orange letters:
"full-res pictures only work in manual (M) photo mode"

but I am already in M photo mode and manual focus.
so I am wondering, Am I missing something in this basic tutorial?

I have got success on Silent mode -> simple: dng and mlv format works great.
Resolution I got is: 1880*1250px.
Also, I cannot see dng and mlv pictures on camera. Only in computer.
Of course, I have load modules: pic_view, file_man and mlv_play and restart cam.
If I take mlv raw video I can see it on my camera but I can not see simple pictures.

Any suggestion? Something I am doing wrong with 5d mark II?
 
thanks,

[a1ex]

Since you can record MLV videos, you are probably in movie mode. Switch to photo mode.

[runtheearth]

thank you so much. You are right.
I was in "stills+movie". I have changed Live view to "stills only".

So basic tutorial for beginners like me would be like this:


camera: 5d mark II
0.1) Set camera to photo mode: Live view settings: stills only
0.2) Set quality RAW+L

1.) Prefs tab -> Config files -> Restore ML default
2.) Restart cam
3.) Activate Silent.mo
4.) Restart cam
5.) Put cam to M mode
6.) Activate FRSP (Shoot tab -> Silent Picture -> Silent Mode -> Full-res)
7.) Activate Liveview
8.) Press shutter half

[Licaon_Kter]

3.) Activate Silent.mo

you need mlv_rec.mo loaded too for saving in .MLV
also press * for AF ( if you set up back-button focus that is )

[Slasheal]

I really want exposure overide to work with my stm lenses... So if there's any test I can to help you determine what's the problem, just tell me

[Matheus]

Press the DOF preview button then turn the lens like 45 degrees. It should disconnect the electronics and lock the aperture to what you set (just make sure the lens is still on camera)

Old trick, but works for STM

[Slasheal]

Thanks for the tip, already knew it. It's a good technique since if you use ETTR with a tiny aperture, it will force the shutter speed to go above 1/10th, and then no much troubles.
Still, i d prefer to have aperture control over stm lenses, of course .

Also, ETTR should have a feature that set max and min shutter time (you can only set the slowest shutter) and also max and min aperture. Shouldn't be too hard to implement I hope.

It would then make ETTR usable for Timelapsers. :p
I have read that I'm not the only one wanting to use it for timelases... The only problem is when shutter goes way above 1/10th...
So meta data for LRTimelapse are unusable.

Also, when using "take pics like crazy" it a bit of struggling to change the parameters manually without introducing shake in the picture, because it needs a lot of try because taking effect.


_{I bought a cheap ND filter: will do the job to help me with exposure. And I just have made a 2k picture timelapse... Overexposed when I felt asleep. Ahahaha. I thought that the weather would have been more shady I will try to get used to doing timelapses.. And then my project as a low-budget-student, is to do a timelapse of the city where I'm studying I'm also composing a music, I will gladly share it with you.}
Thanks

Looking forward to your work @Slasheal!

[Licaon_Kter]

Add the 18-135mm STM to this list, I've tested it yesterday on my 70D (firmware 1.1.1B) and it wouldn't work even with Expo Override...

On my M I had a whole afternoon of fun with the EF/S to EF-M converter and a Canon EF 100mm f/2.8 L IS USM, nice lens, BUT it behaves the same, neither normally nor with ExpOverride, trying to make a FRPS goes to max apperture ( 2.8 ) and snaps an overexposed pic even if I set it up for the lowest apperture ( 32 ) 

[Slasheal]

With the new 50mm 1.8 STM coming... We will need a fix 

[garry23]

I'll most probably get 'told off' for this post, but here goes.

I think many understand the limitations of full silent DNGs (FSDs), but some still think FSDs will simply replace normal shutter actions.

Maybe FSDs will get better, as gurus find tweaks, but from what I understand we will always see a shutter shortfall in the FSDs.

I was thus wondering whether it would be possible to 'hardwire' in the shutter limitations. In other words when shooting FSDs, only ML can control!set the shutter, ie lock out Canon control.

Doing this will bring in some realism and things can be adjusted as alternative ways are found to extend the FSD range.

As I say, just a thought.

[DeafEyeJedi]

Definitely an interesting thought, @garry32!

[Slasheal]

I just realised that aperture work with my stm lenses.. on video mode.

[tidelander]

I just spent several days testing full-res silent pictures functionality.
I used ML nightly build for 5d3 from April 28, 2015.
I tested silent pictures with 2 lenses: EF 24mm f/2.8 IS USM and EF 100mm f/2.0 USM.
Setting aperture does not work on 24mm lens. The photo is always taken on the widest aperture which is f/2.8 for this lens.
Here are 2 images.


Left one is a master CR2 image taken with all ML settings off. I had to put markers indicating distance from tripod in my backyard
The camera was focused on the nearest marker '.8'. Aperture set to f/22. You see that all the markers are in focus.
Right image is MLV image taken with 'silent.mo' and 'mlv_rec.mo' modules. Silent picture settings were set to 'full-res'. Exposure simulation and exposure override were enabled in ML menu.
Camera was focused on the same point.
However, the picture was taken at f/2.8.
At the same time setting aperture works with EF 100mm f/2.0 USM on the same camera with same ML build.
Summary:
1. Liveview says that picture will be taken at f/22.
2. Exif says that picture was taken at f/22.
3. Actual picture was taken at widest open aperture.
4. Setting aperture does not work on EF 24mm f/2.8 IS USM and works on EF 100mm f/2.0 USM.

Sounds like expo override may not work with STM lenses. Any other STM lens users can confirm?

EF 24mm f/2.8 IS USM is not STM lens, but aperture does not work on it too.

[domasa]

for ML-developer:
I have 5DII. Is the problem "Exposure too long (max 16)." in settings in Canon menu?
( Live View/Movie func. set. > Metering timer > 16 sec. )
Can higher value could help?

[dmilligan]

Please read the OP (the "Limitations" section). A detailed technical explanation of the limitation can also be found in this thread.

[mothaibaphoto]

I confirm that

... Setting aperture does not work on EF 24mm f/2.8 IS USM ...

with FRSP. When I try to close diaphragm with rear wheel - it closes a bit, than opens again. I found the only way to make it works - move photo/video switch to video mode. Yes, I got 1/30 exposure time. Maybe it's possible to solve this "video" exposure time limitation with FPS override, for example - i didn't try.
