All About Auto ISO (Nikon Cameras)

Auto ISO is a frequent source of confusion but it doesn’t have to be that way! In this comprehensive video, we’ll cover how Auto ISO works in Nikon cameras (although it’s likely very similar for all brands). We’ll start with what it does, why / when you should use it, how to set it up, and how it interacts with your various exposure modes. After this video, Auto ISO will never stump you again! Check it out!

Outstanding, I was struggling with shooting small birds in varied light using auto ISO and aperature mode and getting the high shutter speed high ISO results you described. Using manual with auto ISO and setting the base ISO as well as max has changed my results dramatically. Thank you for this video, as well as all your helpful ebooks and other tips. I truly appreciate what you do !!!

Very useful explanations, Steve. However, I can not figure out how the auto ISO with Nikon flash is working. I use SB 910 in TTL mode, auto ISO is usually stays fixed to the last setting and not going to change. How is the flash power? I think is underexposing or not working properly.
Any experience?

Fantastic video especially the animation reviewing each exposure mode. I have been using M+ auto iso for a along time for wildlife with and without flash. Could you explain further your issues you had with flash. I hadn’t noticed a problem but suspect I am not astute enough to see the issues you encountered. Thanks

Hi Steve,

One of the first things I learned from you was to use M + Auto ISO. I’ve had my D750 for over two years now and use that mode almost exclusively.

This latest video is such a powerful learning tool that I’m sure many more people will benefit from viewing it. What I love is that every time you state something you then say “for example”, and show us what you mean. Your use of graphical examples is such an excellent teaching method that it makes learning a real pleasure.

Thanks again.

Cheers from Oz.
Terry

Thank You Steve, I have learned so much from you about photography and how to operate my Nikon cameras. D850 and D500. I have also bought all of your e-books and have learned so much more than what you can pack into a video, but, I love your videos so much that I hope you have the time to keep doing the videos too. I live in the Smoky Mountains, and look for you sometimes in Cades Cove, but like a big bear, haven’t seen you yet.

Hi Steve, That was a great video, thanks. You rank with the best teachers out there for clarity of information. As an 80yo I sometimes find you go a bit fast for me to fully digest the content . No matter, a re-run generally corrects that.
Thank you so much.

I have a question regarding the terminology used relating to “minimum shutter speed”. In the example with minimum shutter speed set at 1/500 the camera starts at a shutter speed of 1/1600 of a second (at about 12:00 in the video). Isn’t 1/1600 of a second faster (smaller) than 1/500 of a second? Why is 1/500 referred to as minimum shutter speed when the speed can be faster than that? It seems to me that the 1/500 is the maximum shutter speed that the camera will try to allow, and the camera will always try to keep the shutter speed… Read more »

Think of the speed of the shutter. The shutter speed is faster and therefore greater at 1/1600 than the speed at 1/500. This is why minimum refers to the slowest acceptable shutter speed.

Hi
If it helps, consider what is (too often for me) called “Shutter Speed” more like “Exposure Time” (because that’s what it actually is).
Happy shooting,
Rolando

I am seeing autoISO control Mode M. I think this may have to do with an adjustment I made on one of your recommendations for shooting auto ISO in Manual. How do I get back to regular auto ISO. Right now I cannot set minimum shutter spped.

Sorry for the above post. I was in movie settings. Duh. Everything is now set. Great video.

I’m using a D500 with 200-500 wide open at F5.6 to shoot hummingbirds and other small fast birds in my backyard. I’ve been using auto ISO with aperture priority set to 5.6 and minimum shutter speed of 1/1000, but would like even faster shutter speed if the light was bright enough. So I’ve been setting minimum ISO at 800 to accomplish this, as 800 on a D500 still seems pretty good. Does this make sense or should I be setting minimum ISO to base level anyway?

I suggest using auto ISO in manual mode, then put the shutter speed and aperture where you want them for your subject.

Great video Steve. Got wondering if using Auto ISO would work for shooting day-to-night time-lapse.

Woody Green

I always pick up new info from your vids, Steve. Even though I thought I knew my ISO options backwards and forwards on my Nikons, I did NOT know I could change from auto to normal ISO mode by pushing the ISO button and turning the front command dial. Thanks.

Great Job Steve, lots of great information, I purchased your secrets to exposure and metering for Nikon when it first came out. Steve, I have been doing photography for a while your information and knowledge you have shared is the best information I have ever used you put in a way what is easy to understand, your photo, graphs all made it. Showing the different settings right on the camera was amazing. A person could read the book that comes with the camera and never get the information you have shared. I thank you and would guess all that have… Read more »

Great help as always. I discovered auto-iso from an earlier tip you provided somewhere and it’s been a great help (moved me to full manual). Also good to review the settings. I had no idea that holding the iso button would allow you to switch from auto to manual. I use auto-iso so often that I set up a custom button on my D7500 so I could turn it off when needed.

Thanks again from a fellow NW Ohio native.

Great tip at 4:30 – how to quickly switch Auto-ISO on/off. I tried Auto-ISO before and really liked it, but dreaded the trip to the Menu to switch – Thanks!

Steve,
Excellent video on Auto ISO, very detailed and very clear. That said you were kind of preaching to the converted in my case. I switched to back button focus and Auto ISO shortly after you introduced me to them in your excellent Secrets To Stunning Wildlife Photography and I’ve never looked back. It’s impossible to overstate what a positive effect these two techniques have had on my photography and I shall forever be in your debt! Thanks!

Once again a nice review of Auto ISO Steve.
The only downside I find to auto ISO is when shooting birds in flight as it exposes for the sky and not the animal, as such, I kill it when shooting into the sky.
