M8.2 instructions? Auto iso

In the SET menu set the ISO to Auto ISO (at the top of the list when you hit the SET button with ISO highlighted).

In the REAL Menu (Menu Button) scroll down to Auto ISO Settings and set you lowest shutter speed, or Lens Dependent, and the MAX ISO you want the camera to go to.

 

NOTE the lens speed setting is just a trigger for when to raise the ISO.

Very simple and straight forword.

 

Then I'd svae those settings, along with your other normal settings like review time/date sequence and the like, to a User Profile #.

That way you can always go back to it when needed.

so when I'm in aperture priority mode, the camera will change shutter speed and then raise iso (after going to the lowest shutter speed set) - instead of just changing shutter speed?

okay, I could see how that would be useful!

I guess this is what the 'snapshot mode' in the M8.2 does - without having to change user profile #

Yeah I think so. someone else posted that is basically what Snapshot mode was, for those that don't know how to change the settings.

Hi

have upgraded to new firmware 2.0 but unsure how the new menus/Auto iso is used. The upgrade instructions say to look at m8.2 instructions but can't seem to find it on the leica site?

 

One small catch: the firmware upgrade is free but to get an M8.2 manual you have to buy an M8.2 :D

I understood, and therefore may be wrong ;), that snapshot mode set auto iso and auto white balance.

Well I think you are right but I think it also sets the camera to A mode and lens dependent for Auto ISO. It is a All Auto feature. Something I'd never use.

How will auto ISO behave if you don't use Aperture mode, but set aperture/shutter manually? Will ISO be increased in low light somehow? Or is Auto ISO only for A mode?

ISO increases itself in low light if you set av/tv manually, at least on the m8 with firmware 2.0

Have no idea what shadowplay meams by av/tv.

But Auto ISO will work just fine with manual shutter speeds. You will get a flashing arrow, left or right. If you are overexposed, right arrow, and the ISO can't go any lower (then you need to increase the shutter speed or stop down) or underexposed, left arrow, and the ISO can't go any higher (then you decrease shutter speed or open up the aperture).

 

It really is a good feature.

And appears to be more sophisticated than that in the new Canon 5DII.

 

Quote from Rob Galbraith DPI: Canon EOS 5D Mark II - 21.03 million image pixels, 1080p video

 

ISO The camera has an ISO range of 100-6400, in 1/3 step or full step increments, plus ISO 50 (L), 12,800 (H1) and 25,600 (H2). The Auto ISO range is 100-3200. It's not possible to manually select a maximum ISO within the Auto ISO range, or a minimum shutter speed.

 

My emphasis.

Can you (or anyone else) clarify what exactly the "lens dependent" setting means? I can't quite work that bit out...

 

Thanks! :)

Leica: thank-you, thank-you, thank-you for auto ISO!!

 

I used the new firmware yesterday over some 900 shots or so at a wedding, and auto ISO was stupendous.

 

I shoot manually, and I usually know where my exposure is, but I used auto-ISO in the church setting.

 

For the very first time ever, with any make of digicam I've owned to date, I didn't have to worry about running back and forth between the dark interior of a church (it was candlelight--the power had gone off!!), the foyer (light coming in from the street) and the late afternoon sun outside!

 

I'm so happy about this--it's almost like getting a new camera!

 

Oh--there are some other nice things in the new firmware too, not the least of which is real refinements in the way the M8 is writing to cards...

 

(@ Ed--PS--av = aperture value and tv= time / shutter value).

The lower limit of the shutter speed at which the ISO will change is different for different focal lengths. Thus a 90mm will change at say 1/125th whilst a 21mm at 1/15th (just speculative values no doubt a tester will run through them all and post a list). Obviously hand holding a wide angle will return shots still sharp when a telephoto will show shake.

 

In "manual" you can set your own limit of speed at which the ISO will change. so if shooting fast action you may want to not drop below 1/250th so you can set that.

Not to belabor the point, but if you have it set for 'lens dependent' and you fit an uncoded lens will it by default revert to 'manual' or just be bewildered and confused?

I also like the new auto-iso-feature for the M8 (have used it all the time with the D300 and D3). The lens-related setting is great to (with Nikon I have to change the shotest shutter time myself when I change the focal length).

Today I had a 50mm lens on the M8 but found that the ISO had been increased to higher ISO even though the exposure time was short enough to work with lower ISO IMO. (something like 1/180). I would have expected that the camera would choose maybe 1/60 or 1/125 for a 50mm lens and then increase ISO but not at 1/180.

Any thoughts/experiences?

cheers, Tom
