Hello,
About to take the kid to a class zoo outing for Asia day. I'm bringing along my D700 with both my f2.8 lenses. I'm using a polarizer. I'll use Manual setting shutter above 1/200 on my big lens and adjust fstop as desired for DOF. I'd like to use auto ISO and think the D700 would handle this well. I'll put a cap at ISO 5000.
Besides some noise in the dark areas at ISO 5000, is there any other drawback to using auto ISO ?
Thanks, |

If you shoot in manual and want to control the light and exposure yourself, you don't want to use Auto-ISO as it is using the auto feature to control the exposure. If that is not a big deal for you, go with it. |

Yes...using manual but my thought was...Say I'm in a spot and want to use 1/800 with f10. If not in auto ISO and I REALLY want 1/800 and f10, then won't I have to adjust ISO in order for my settings to expose correctly? I'd like to have total control over shutter and app. and let ISO adjust as needed.
From my understanding of my cam....if I have total Manual then that won't be changed by the cam...only the ISO...correct?
Thanks for the help.

I would think that for shooting at a zoo you could just shoot in aperture pilriotiy with you auto ISO on. The only time I shoot in manual is if I want some motion effect. In a zoo setting you want as fast shutter as you can get and your main concern will probably be DOF, unless it's a rare thing like a panning shot of a big cat running through it's enclosure.
I recently went to the San Diego Zoo on vacation and I shot in aperture priority and set my auto ISO at 6400 with a minimum shutter speed and 1/250 and came away with a bunch of very nice shots (nice shots for my limited talent anyway).
Just throwing that out for you as an option. Kids at the zoo can get very hectic, fun but hectic, it might be nice to have less to have to think about.
As for your original question: I believe your understanding of it is spot on. I don't think you'll have any issues if you go manual and set auto ISO at 5000. Good luck and have fun. Zoos rock! |

Sounds right. Just keep your eye on the exposure meter (I assume it's in your viewfinder, it is on my Canon). The D700 handles noise quite well, so as long as you get the Av and Tv you want, and the exposure indicator hovers near 0 (again, Canon), you should get some proper exposures.

My Canon 400D doesn't have auto ISO, so until I got my 7D, I didn't know what I was missing. Now I find I use it more often than not when I'm shooting hand-held. It's really nice not having to worry about camera shake most of the time.

Shooting in Manual allows you to control exposure better - even better than spot metering etc. The advantage of Manual is that you are in full control and can select what portion of the scene to have exposed at a certain level. This is especially useful when shooting in hard lighting situations. While most of the time the auto modes - aperture priority and the like - get you close to the correct exposure for what you are trying to capture - it is guessing.
The Auto ISO on my D300 (and I would imagine it would do the same on the D700) is to auto select the ISO so that the camera balances the exposure. So, in reality, if you are shooting manual, the AutoISO is controlling the exposure.
This can be great if you know that you want a specific f-stop (depth of field) and specific range of exposure times. So combining AutoISO with Aperture priority is a powerful and great tool - it all depends on the settings you are using. |

Yeah I love it.
I let ISO float between 80 and 32000 and it works a treat for macros or any other situation where you have a preferred aperture and shutter speed.

Thanks all....I shot about 85% with auto ISO and got good results. I may have a few for free study and maybe one of the other current challenges so I'll only post a few of the "others" later.
I have to say, the midday sun was HARSH and it was a challenge shooting anything that wasn't in full shade !
