Is there a way to assign a button which can change the aperture to a preset value? If I’m in Aperture mode, and let’s say I’m happily shooting a still subject at F8, with a shutter speed of 1/250 and suddenly I need to pan to capture a fast moving scene (cheetah chase comes to mind! Or a bird comes flying in....). I’ll suddenly need to bump up the shutter speed to 1/1600 or 1/2000. Instead of fiddling with the aperture disk and adjusting it to calibrate to the right shutter speed manually, is there a way to assign a button on the camera that would immediately bring the camera to a pre assigned F stop value (eg 2.8) to bump up the shutter speed? (ISO on manual at a low value). Or.... is there a better way to handle this ?

I shoot in manual mode with my D500 set on ISO AUTO with a ceiling of ISO 4000 for most subjects..IE tyhe ISO floats for what ever you have set for your Fstop and shutterspeed.. Check out : StevePerry's e-books and videos at http://www.backcountrygallery.com

Thanks I’m aware of your advice regarding auto ISO range and I’ve used that often. The downside to that method is that in M mode you have to fiddle with two settings - aperture and shutter speed - by which time you may have lost the shot. If you are in Aperture priority, and you preset to a manual ISO (which is not going to change even if there’s a sudden need for a higher shutter speed) then by simply changing the Aperture ( thus only one setting instead of two) you can automatically change the shutter speed. That’s why I asked if there was a button to take the camera to a pre assigned shutter speed - which would make that even quicker.

There is no one-click button I’m aware of. But if you’re in A mode and adjust aperture to 2.8 in the light you describe you will require a 1/4000 shutter. That would be 12 clicks at 1/3 stop increments, which is allot. I don’t own a Nikon but I know you can adjust shutter increments to 1/2 stops or maybe even full stops to get you to a faster shutter speed quicker.

Yes understood. The numbers I had given were not exact just random to illustrate the point. Thank you for confirming there’s no button assignment possible. I wonder if the Canon menu has that facility.

You’ll find every possible available setting in the appropriate user’s manual.

Thanks. I asked because I couldn’t find it. Perhaps I didn’t look hard enough. Do you know where to find the answer to my question ?

The short response is no.

The options in aperture-priority mode are pretty limited, so if that feature existed you probably would have found it. I think, though, that you can do what you want in one of the program modes. Good luck!

This is the "easiest" way to do it, that I am aware of (although I don't have one of those cameras)
Not a direct button, but you could set one of the U1, U2, modes to the aperture you want as default. Then use Av, and instead of pushing a button as you said, you would switch to the U mode.
(although this would require other settings as shutter speed an probably would be useful to have auto-ISO then).

You cannot do it the way you want to. HOWEVER....

If I understand you correctly, you want to know if there’s an easy and fast way to switch to a fairly fast shutter speed when shooting in Aperture mode. When I want to switch back and forth from A mode to a shutter speed that I determine is I 1st put my camera in S mode, set the shutter speed to whatever I think I’ll need when that bird or Superman flies by, switch the mode dial back to A mode and shoot away. When that bird does fly by I’d simply switch to S mode. As long as you haven’t changed your shutter speed, it will remain at whatever you set it right before you switched to A mode. On the D500 I pretty much need both hands to switch modes, so I changed the red movie button to function as my mode change. All you would do would be to put your finger on the red movie button and rotate the rear command dial to S. FWIW, I normally shoot full manual. However when I’m in a situation such as you described, the method I use is what I described. It is extremely easy to switch back and forth. Of course, you can adjust the shutter speed to anything you want once you are back in S mode.

I doubt you will find a one button solution. Have you tried diving into My Menu & the extended Menu banks. Could probably set one up to shoot in A mode with a minimum shutter & auto iso & ev stops to 1 full stop per click on the dial. Then all you have to do is spin the dial to your desired Aperture.
Let me know if this works.

I would say we have a winner as the best approach

Great idea, Mike!

Thanks, Ben! Works for me.
