Auto ISO: How do YOU use it?

I would appreciate a simple description on how to use this feature.

I have an M8.2.

 

The instruction book gives sparse instructions

 

thanking in advance for any help

You just set your own parameters--the slowest shutter speed you're comfortable using, and the highest ISO you want the camera to go to, which will depend on the amount of noise you can live with. For example, I have mine set to a shutter speed of 1/15th with the ISO maximum of 1280. The camera will then operate between those parameters when you have the auto ISO turned on.

My M8.2 does not seem to work quite the way you describe above relative to shutter speed. It will not go above the max ISO setting I select in Auto (640 for me) but it will go below the minimum shutter speed I select. For example, I also chose 1/15th but in practice it will fall to 1/8th or lower. I don't know if this is a camera malfunction or an over ride feature.

 

Thoughts from all would be appreciated as I am a new user.

Max,

 

If the shutter speed drops below the parameter you've set, the speed should flash in the VF to tell you that you're working outside the envelope you've set. The camera will still take the shot at the flashing speed but it's the camera's way of telling you that it's done all it can to help you to get a decent shot and you're now on your own. You rebel, you!

The shutter speed setting is just a TRIGGER to raise the ISO. If the camera didn't go below the set shutter speed you'd get underexposed or black images.

What would you want, the camera to always take a properly exposed picture when you press the shutter release (Even if it went below your set low limit shutter speed), dark or black images or NO image at all.

I usually just make a mental "tsk tsk" when I read patronizing remarks, but this time I'll actually speak up. I avoid the Leica forum discussions, usually, because of too-frequent mean spiritedness like Shootist's remark.

Actually I don't see it as patronising at all. Shootist is correct. The camera has a choice, does it take a picture at a low shutter speed, or does it take no picture at all. I think most of us would prefer that it takes the photograph.

I didn't find the post patronising either. Ed 'says it like it is' but the web is not a great vehicle for conveying meaning so I find that honest intentions are sometimes unfortunately misread as having hidden meanings.

What is mean spirited about my post? I pose the question what would you want it to do trying to show this is and should be normal behavor.

OK here is something you may take as mean spirited. You have either been living in a bubble or you need to get out more.

Come on guys - lets chill for 2009 !

 

Unless this thing is live by video link there will always be misunderstandings.

 

I for one have spent the afternoon comparing C1 with Raw Developer - thank you to whoever it was who revealed that this program was around - pity it doesnt do windows!

I have tried both lens dependent setting and a low shutter speed started with 160 ISO. pointed the camera from 1/60 sec to 1/2 sec, it took the picture each time .... but I never noticed any ISO change ?

 

Is there a way I can test it to see if it's working?

 

and .....

with regards to the above bickering;

It is probably shooter's use of CAPITAL letters that causes his comments to "appear" as mean spirited

You need to look at the image either with the Play button or on the computer to see if the ISO has changed.

I find the ISO change to be seamless, IE the camera never tells you it has raised or lowered the ISO.

I saw the the ISO was never changed using the "Play" button. Should I not be able to see the ISO being changed? The camera seems not to be adjusting the ISO.

[Red Dot]

Yes, in play the camera shows speed and ISO as taken and yes the camera should adjust ISO.

Well then it's not working

 

thanks

If you want to use "Lens Dependent", you do of course have to use coded lenses with lens recognition switched on...

I have auto ISO setup for 1/30 / 640 / Camera 8.2 / 28 mm Elmarit 2.8 / lens detection on+uv/ir / EV +1/3

 

I just pointed it at my screen .. first image at F 2.8 (Camera selected ISO 160 1/125) , second image at F 22 (Camera selected ISP 640 1/12 and flashed in the view finder telling me I was out of my preset range of 1/30)

 

Sorry to hear your camera is not working

Rafael--

You know there are two menus under which you engage Auto ISO, right?

 

First, under the general "menu" you set the Auto ISO parameters--at what shutter speed it engages and how high it goes.

 

Second, under the "set" menu, you set ISO to AUTO.

 

In other words, the first menu sets up how Auto ISO will work, but then you turn it on in the "set" menu.

 

Since this is firmware, I don't see how it could fail to work, and I'm hoping it's just oversight and not a bad camera.

 

Good luck.

It's probably just an oversight, on my part. I will have to re read the posts.

Firstly, and this makes me think it is 100% my brain's firmware ............

is I thought the parameters were the markers for "above which and below which" the Auto ISO came into effect.

Your saying the parameters decide when Auto ISO begins and how high it goes, is different.

It's probably me, not the camera.

But thank you for your reply.

Yes Rafael. The AUTO ISO Setup menu option is to set the HIGHEST ISO you want to use and the slowest shutter speed the camera drops to before raising the ISO.

If you set the AUTO ISO Setup setting to 160 then it has no room to go anywhere.

Maybe someday there will be a high and low ISO option but for now the camera will always use ISO 160 when there is enough light to keep the shutter speed just above your set low limit.
