SL2 issue with exposure simulation in Manual mode

Recommended Posts

Disclaimer: I am very new to the SLx firmware, so it may be user error here, but thanks in advance if you can solve this issue.  
 

Does anyone have an idea how to turn on permanent exposure simulation when the camera is in Manual mode ( set aperture, set shutter speed, auto iso)?  The SL2 will not preview the exposure even when the shutter is half way pressed.  I think it’s the autoISO that is disabling the exp preview in Manual mode.  When you use exposure compensation in Manual mode, it doesn’t change the look of the preview on the lcd at all, the exposure doesn’t seem to change until you take a picture and then see the screen as all black or washed out.  

I had the same problem with the Q2, I posted there a few months ago without a solid answer to the issue.  

Even when the exposure simulation is set to PASM, the exposure (f stop, shutter speed and iso) is not simulated when looking at the rear LCD or through the view finder.  

On the M10-p, this is not the same deficiency of exposure preview at all.  On the M, With the shutter set, the aperture set (manual lens of course), and the iso on Auto, you can change the Ev compensation and watch the preview react by brightening or darkening without having to half press the shutter.  The live view reflects the shot you are actually taking, unlike the SL2 which does not display how bright or dark the shot is going to come out.

@jonoslack I hate to bother you again, but seeing as you are the resident Leica expert, please see the post above for my question regarding the exposure simulation settings.  I have yet to find an answer to this on this forum and elsewhere.  Thank you! @sean_reid (if this is in fact your username) your help is always appreciated !

Looks like Sean hasn’t logged-in since 2015, so it’s up to you Jono!

Well, you could subscribe to Sean's site and then email him your question. :) We haven't seen him here in years, as you found.

I subscribed to Sean's site when I purchased my first camera, an M-P 240.  Even though that was only about a year and a half ago, I've enjoyed the reading/viewing thoroughly.  He also has been accommodating enough to answer a few beginner questions as well.  Great site, author, and photographer.

It sounds like a firmware bug that Leica have not noticed. I suggest emailing them with your observations.

The fact it works as expected on the M10 is the giveaway. 

Although it is many years ago I recall something along the same lines with the original M240 that was later fixed with a firmware update.

It works like this on SL, I often use manual mode, Auto ISO and exposure compensation.

I have tested SL2 in Leica Store the other day and I am almost sure that I did configured the camera this way, too. I do not recall experiencing anything unusual, it just worked as I expected...But then of course, I could remember it wrong, maybe I didn't use camera like that after all...
Anyone that can make a quick test?

This is how I normally use my SL and if that doesn't work it would be a huge set back for me...

I just tested with my SL2 ... here is what I found .. when in M exposure mode with Auto ISO.  As you change your exposure the camera will keep on adjusting the ISO. Therefore the exposure preview stays in (( in its natural position)) until you run out of ISO range , then it starts to dim or wash out.  Because the Auto ISO is not letting you to overexposed or under expose . 

If you had your auto ISO set to say maximum 400 you will see this

I just checked: When I set Aperture, Shutter speed, and ISO manually, the EVF provides instant exposure preview.

Same settings but with Auto ISO, see Artin's post.

All good....

"Change your exposure..." Just to be sure - how did you do that? You used "exposure compensation" feature in this scenario ( Auto ISO, M )?

Not only altered aperture and/or shutter speed? ( by doing this you get the behavior you described - also on SL - and that is fully expectable, too)

I wouldn't say "all good". It is not working like this on SL nor M.
In AUTO ISO and M -mode you alter ISO value when using exposure compensation (aperture and SS stay unchanged ) and exposure preview is altered according to that.

You say SL2 doesn't behave like that?

Luckily today is a short work day.  Will identify the cause and exact settings.  I started a Q2 thread on this point a few months back with many others agreeing and also PM’ing me that they could find no fix.  
i think when you “run out of iso” (mentioned by someone above) the camera no longer displays permanent exposure simulation, it converts to only displaying exposure simulation when the shutter is half pressed, and/or not at all.  This may be a Leica firmware behavior that is known and intended unfortunately.  We will see later today with testing.

I really do not understand where you coming from .... when in Auto ISO  you do not have the ability to use exposure compensation in the same manner 

the Camera is trying to keep the exposure to what it deems to be accurate ..... in the M what you are basically setting the camera to over expose or under expose all your Images for as long as you see fit  .... But as you adjust your exposure , by the shutter or aperture .... as long as you are in Auto ISO the camera is going to adjust the ISO to keep the same amount of light sensitivity.. Therefore your EVF or your Screen will not shift. exposure compensation is telling your camera to push or pull your exposure globally ,, its not for over exposing or under exposing on each individual image .. therefore it is pointless to use AUTO ISO in manual mode

The SL2 provides instant exposure preview - also in M mode with Auto Iso and exposure compensation (positive or negative). 

All good.

When "running out of iso" my SL2 provides exposure simulation when half pressing the shutter button.

Same here Artin, I actually never use Auto ISO in manual mode.

However, the SL2 offers this option.

And it works just fine.

I Know it works fine but how is that manual exposure ??? when you still have a Auto setting that effects exposure selected by the CPU.

The way I see it is like this ... This is a Professional Camera at the Apex of the full frame Format. they have provided us with everything you need to create incredible images 

at price ticket of entry into this system it certainly is not for point and shoot therefore the thinking is right. If in manual mode??  then make every choice. do not rely on the CPU 

Leica has it right

      Hi,
      I just got the SL2 couple of weeks ago. Upgrading from SL1, I expect the buffer size of DNG to be more than SL1. But it turns out the buffer of shooting DNG in hi speed burst is 26. I am using UHSii Sandisk with 300mb/s. Many reviews I have read claimed that 78 raw files can be taken with burst mode. 
       
      I have tried to change the DNG file to JPG but the maximum buffer I can get is 44.
       
      Anyone has comments about this
       
      Thanks

      LEICA APO-MACRO-ELMARIT-TL 60 f/2.8, silver - (#4629438) is in great condition. I rate it cosmetically a (90%) but optically 100%. The focus is smooth, the autofocus and aperture function properly, and the glass is clean and clear with no haze, marks, or fungs, scratches. This lens includes a Leica lens pouch, a Leicalens hood , front & rear caps, and the original instructions & box(full factory set)
      I'm the owner from new. The lens was bought new at the Leica store.
      Payment: paypal or bank tansfer directly to my bank
      shipment: UPS with international tracking - 50EUR
       
      It's not only macro lens. It's excellent for portrait and mid telefoto (fov=90 mm with CL/TL camera)

      The lack of a tilting display on the SL2 makes it  difficult to shoot from low or other than eye level angles. Has anyone tried to put a secondary display, say mounted on the flash shoe so that it becomes easy to see the with  low or difficult angles. I saw using the Atomos Ninja for also recording video. Can the iPhone mounted on the hot shoe be a possibility or any other display option?

      Apologies if this topic is already in the system by me, but for some reason I could not find what I had posted.
      Anyway the issue I seem to be having since updating the firmware to v2.0 is that I have had a couple of crashes, or my camera locking up.  The on/off button does nothing, the OLED display and LCD are still on.  The only remedy to reset is to remove the battery.  So far its happened 3 times.  Anybody else experiencing this?
