- In this video I talk about how to set the correct ISO in your camera manually and why I don't like the AUTO-ISO function by highlighting the shortcomings of this function in today's cameras.`
The problem described in the example is describing AUTO-ISO in the context of aperture priority. I am aware that there are cameras with shutter priority mode. Not the Leica M series though.
This might change in the future since machine learning and artificial intelligence finds its way into cameras. There is a good chance for smart scene detection in the future.
All photos in this video were taken on my Leica M-D 262.
I hope you enjoy the video and I would be interested in your opinion in the comments below.

How lucky am I stumble upon these videos! My brain is still wired to a large degree in the film world I formerly inhabited. ASA/DIN were set parameters once the film was loaded with only small ability to “push” film speed. I will never use auto ISO after watching this video. Very well explained, sir.
Thank you for your kind words Charles. Feeling Gratefu 🙏l
I love auto iso. I shoot manual, with the aperture I want, the shutter speed I want, and I have the best iso possible. Coming from films is a dream!
Hehe, yes coming from film it’s a dream ;-)
Great videos Marcus, thanks for taking the time to do them. Can you please do a video on different techniques for focusing with a rangefinder?
Thank you very much. I have the focussing topic in the pipeline and it will most likely be video #5. 😊
After buying the M10-D a few days ago, I am so angry at the ISO knob. Why on earth did they do that. The M-D is much more beautiful and ergonomic in that sense. But I do love mine too.
Yeah, I also think the original M-D was amazing from a design perspective. Simply perfect if you ask me. But the M10-D is brilliant with its low light capabilities and overall superior imagine quality. Congratulations to your M10-D
Thanks, I very much appreciate your help and I’m really enjoying this great video.
Keep it up please 👍🏻👍🏻
When shooting street, auto iso actually is a very neat feature cuz you would rather have a grainy image than a blurry image most of the time. With zone focus your aperture is set, then you give it a shutter speed of say 1/250 or more depending on the movement of the subject. When iso is auto, you don’t have to worry about exposure when adjusting your shutter speed. But like you, I enjoy shooting full manual a lot.
Fully agree with what you say. If you know what you are doing auto iso can be handy in some situations. Depends a lot on shorting style I guess.
Another Great video Markus with excellent explanation, thank you.
Thanks a lot Phil!
Great vidéo Marcus !
Auto ISO can be very valuable in manual mode, I.e. when you set the aperture and shutter speed to create the visual effect you want, then the camera sets the ISO for an appropriate exposure.
Thanks for watching and your feedback. Agree. It's about the only mode where Auto ISO makes sense to me.
Thank you! I thought I missed something.
I should have mentioned it but at the moment when I did the video it slipped.
Great video... I am curious if you can think of any situation where one would chose to shoot at a higher ISO than the minimum needed for the Aperture and Shutter speed desired? In other words, we change Aperture to change depth of field, and we change shutter speed to freeze motion or not, so they affect the image directly .. however is there anything to be gained by using a higher ISO than needed? I think not, right? One should always use the lowest possible ISO for the given shutter / aperture desired, right?
Absolutely. Lowest ISO possible. Couldn't think of a situation where someone would choose a higher ISO than the one needed for the aperture and shutter speed they would need for the subject. It would only produce more grain.
I guess it’s like with every function on the camera, you need to know what the camera does. The automation is not meant that you you leave your brain at home. It very important to know the triangle and what does what. But once you know all that, Auto iso is a very cool Tool. I use it in M and if the light conditions are changing often. In sunset and sunrise it’s very helpful too. And when I am experimenting with composition it’s also very helpful.
Thank you Peter. I agree, that it can be helpful. I sometimes use the function on the CL. To get the best out of it one really needs to understand the triangle, as you pointed out. The brain should definitely not be left at home.
The problem with manual ISO is that you can’t always plan a shot. I understand landscapes and things like that. My Leica M has an auto iso setting and I set it at maximum iso 3200 and shutter speed at minimum of 1/250 for daytime shooting. I can’t be worrying about iso. I think iso is a film problem. Most of the time I can just be in aperture priority and that’s it, the camera can choose the rest. And it gets it right 90% of the time. Sometimes I need to take control of the shutter speed and I can do that. ISO is such an antiquated thing to be worrying about. If I need to overexpose the scene to expose the subject in bad lighting situations I can just use exposure compensation. It’s fast and more accurate than relying on the arrows.
I have friends who swear by all manual all the time but for me it just creates an unnecessary problem. ISO is just a relic of the film era.
Thanks for your comment Carlos. I can see your point of view. Happy to hear that Auto ISO works for you as you expect it. I can definitely also see that there can be a solution around ISO in the digital age. But for now we are stuck with it even on digital cameras
@@TheMPhotography For me fully manual is aperture and shutter speed. I let the camera worry about ISO. As long as the auto iso settings are set, there’s no problem. Since it won’t dip below 1/250th, aperture priority is best for most situations. Obviously if I need to freeze a pigeon I have to get a hold of my shutter speed and set it. Or if I’m walking and shooting at the same time. Maybe it’s worse with older cameras, but with newer cameras, ISO is the one setting you really never have to touch. I would be so busy turning dials I would miss every shot.
Good explanations as always! But I find it misleading when what you actually are talking about is auto ISO in aperture priority mode. That should of course be avoided but as other people has pointed out just having auto ISO is great, outside perhaps really slow photography like landscapes. If I need to change all settings every time depending on the subject and light a lot of moments will be lost, especially in low light.
Does the M-D not have variable auto ISO shutter limits? I use Auto ISO on my M240 and I can easily set the minimum shutter to 1/250, 1/500, 1/1000, etc.
It doesn't have auto ISO, no.
@@TheMPhotographyOh, interesting. I guess that makes sense, as it can't be adjusted without the screen.
On the M240, I can swap to auto ISO mode, set my shutter gate to 1/500.. then just focus on composition and aperture is my only variable. Helpful around NYC, where freezing all motion is often the goal. It's cool because you can meter off the highest value in your shot with a half shutter press, then quickly recompose, or you can roll the thumbwheel to use exposure compensation to lower the ISO (shutter is locked, aperture is manual, so the wheel can only change ISO).
Pretty helpful mode to have handy! It's a bit new school compared to the MD, which is proper film-like... But if you know the exposure triangle, it's a great shortcut to expose.
@SourPlanet on the M10-D one can set the iso dial to auto and configure it via the Leica app. The original M-D is more puristic and has no WiFi or Bluetooth connectivity.
@@TheMPhotography M10D looks like a very nice camera, but they are prohibitively expensive imo. These old models are so good though, I don't see too much reason to upgrade.
I second that. I never felt tempted by the M10-D.
Auto ISO is usefull if you’re going manual on aperture and shutter speed !
Yeah. That's about the only useful combination of these three main photography parameters where auto ISO makes sense because one still is in control.
It’s a great video Marcus !!!
I like your channel a lot 😉
Thank you Fabienne et Philippe 🙏🙏🙏
@@TheMPhotography I disagree. When I'm in full manual control, e.g., when using off-camera flash, I don't want ISO moving in line with aperture or shutter speed changes.
I don't agree. If you want to catch a fast moving object, like a train, just choose a fast shutterspeed with a wide aperture. A wider aperture will already compensate for the tiny bit of light that a fast shutterspeed gives you. If the compensation of the wide aperture is not enough, auto-ISO will just compensate a little more to get the exposure right. If the wide aperture is enough to compensate the exposure for the fast shutterspeed, the ISO stays low in auto-ISO. If you don't use auto-ISO in this situation, the train can be gone.
I agree with you under the condition you mention. Namely you do not shoot in aperture priority mode and take full control over your shutter speed. Then auto ISO really can be helpful if you are being caught off guard.
The aperture is manually set, so is the shutter speed, then auto ISO just helps find the correct exposure, what is the problem? You don’t have to set shutter speed to auto.
The problem is that if you then change the aperture auto iso will follow your change and compensate your change over and over. So the question is, does the auto function know what the correct exposure is? For example like I showed with the moving train.
I think what Markus is implying is that the auto iso will compensate to get your correct exposure, but it will not understand your artistic priority for the shot. As in the train photo, the artistic priority was to freeze the moving train.
Thanks for putting it in such concise words.
Tu ressembles tellement à Keegan-Michael Key ! haha :)
Haha, first time someone tells me this.
Sorry, but I don’t think you understand how auto ISO works
