Auto ISO settings

Hi guys,

 

I have a question about this setting: I always set maximum iso at 1600 and minimum shutter speed at 1/15.

 

But when I shoot, shutter speed doesn't goes down 1/30. I've tried set the minimun at 1/8, just to try, but still doesn't goes down 1/30.

 

My guess is that the camera, first push the ISO to the max you set (maintaining 1/30 which is the "minimum" of the lens), and then, puts the speed down if it needs it.

 

So, what's the point of this setting if the camera?: if I set to 1/15, I think the camera should do the oposite: set speed to 1/15 with the minimum ISO available, and push the iso up only if needed not to go down 1/15 which is the minimum set...

 

Am I missing something?

 

 

Thanks in advance

You're right. I agree it would be preferable for the shutter speed to drop to the preset minimum before the ISO increases, but even if the minimum shutter speed is set to 1/15 or 1/8, it only drops to 1/30 before the ISO begins increasing. According to the manual, "the priority is to raise the ISO sensitivity first," which does seem to make the minimum speed setting superfluous.

Thanks Rocky, I missed that quote in the manual. Now it's clear to me that Leica has set the camera not to drop speed under 1/30, and only doing it in case of reaching top high ISO setting...

Great thing about this camera is that when/if it gets in it's own way you can go full manual and turn a dial....
