If you're trying to turn off auto-ISO, then presumably you want to set a particular ISO. And, if you do that, auto-ISO will indeed be turned off. You can turn it back on again by choosing "auto" on the ISO selection, rather than 100, or 800, or whatever you decide. What I might have to refer to the manual for is how to set the upper and lower limits for the auto-ISO range, but that's a rather different question. -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.

Re: K-1 Turning Off Auto ISO
It's something I don't really think about. I go through all the menus with every new camera -- I've owned all with the exception of the k-5 II-- and just set everything to my liking. The K-1 is undoubtedly the best of the breed, and I'm sure it's replacement will be better yet. I'm at 13,000 exposures, so I'll probably need it by the time it's released.

Re: K-1 Turning Off Auto ISO
Well, mine may have come that way as well. Don't recall, but I usually started with aperture priority and set ISO to what I wanted. If the camera came preset with something else I never noticed.

Auto ISO
Auto ISO is one of the features added to my DS with the last update. I switched it in this afternoon while taking more bird pictures. Aside from the discovery that I am not as fast as a hummingbird, I could not discern what AUTO ISO added to the picture equation. Is there a discussion of this feature somewhere that explains what is is how it operates? For instance, does it start at the last set ISO level and move up or down based on some ideal setting of aperture and speed. Does it require that I select one of the modes to make it work.

Re: Auto ISO
In reflecting on the feature, it seemed to me that something had to be fixed, and so at the very minimum it would only work in the picture modes, and probably in the Av and Ty modes, but I couldn't find a way to do an in cameras test. Going into RAW processing I could see what ISO level was used but I haven't done that as yet. Ah hah..After some reflection, I went out and set the ISO to Auto and took a picture. If you bring the picture back to the screen for review and hit the INFO button twice, the shot parameters are shown. In this case it was ISO 800 and I was in Av mode. In flower mode, it set the ISO to 1600 so it appears that the aperture and speed are set and the AUTO ISO moves the ISO setting to make it happen. Interesting.

I couldn't get the camera to set an ISO higher than 800. There seems to be a built-in limiting ISO that is not able to be set by the user (unlike the K bodies) and, based on your tests, the limiting ISO might be different depending on the shooting mode set.

My understanding (and this could be completely wrong) is that Auto ISO allows the camera to adjust the ISO to suit the lighting conditions. So, if you were shooting in Av mode and set an aperture that would give a shutter speed too low for hand holding, the ISO would be increased to achieve an acceptable shutter speed (or as high a speed as possible). At least that's how it seems to work with the K200D. With the 200D (and I assume the other K series bodies), you can limit the range over which the camera is allowed to increase the ISO. That doesn't seem possible on the DS, so I assume (a lot of assumptions here!) that the camera can adjust the ISO right up to 3200 with the AUTO setting, if necessary.

Re: Auto ISO
Who knew Would be wonderful to have a mini-manual to print out when they do an update John Graves WA1JG jh.gra...@verizon.net Fernando wrote: Hi Brian, This can be set in the DS by using the custom setting menu, opcion ISO Corction in AUTO (ooh, those beautiful option names Pentax used to use...) you can select any of these options: ISO 200-800 ISO 200-400 ISO 200-1600 ISO 200-3200 Didn't check but I believe my *istD has similar options On Sat, Jul 25, 2009 at 7:45 PM, Brian Walterssupera1...@fastmail.fm wrote: On Sat, 25 Jul 2009 19:08 -0400, John Graves jh.gra...@verizon.net wrote: In reflecting on the feature, it seemed to me that something had to be fixed, and so at the very minimum it would only work in the picture modes, and probably in the Av and Ty modes, but I couldn't find a way to do an in cameras test. Going into RAW processing I could see what ISO level was used but I haven't done that as yet. Ah hah..After some reflection, I went out and set the ISO to Auto and took a picture. If you bring the picture back to the screen for review and hit the INFO button twice, the shot parameters are shown. In this case it was ISO 800 and I was in Av mode. In flower mode, it set the ISO to 1600 so it appears that the aperture and speed are set and the AUTO ISO moves the ISO setting to make it happen. Interesting. I can see why you would want to set a usable range of ISO speeds if you were going to use this feature as it is not displayed in the eyepiece. I just did a few test shots with the DS in Av mode. I couldn't get the camera to set an ISO higher than 800.
