Why does many shooters use Aperture priority?

Not that you are in constant motion, but I choose a fairly wide open f-stop to allow some of the background to be in focus


If you do this, then Av sounds like the perfect mode for you.

You obviously know what you are doing so I'm not going to insult you by explaining anything technical about exposure.
I use Aperture Priority mode when I want to control the background and have ample light to either pick a specific ISO or let the camera do it, and I know the camera is not going to give me a shutter speed that will result in a blurred image. This way I can concentrate more on what I'm doing and spend less time turning dials on the camera. If timing is not an issue I usually shoot manual but, to be honest, I didn't spend thousands of dollars on top shelf cameras just to show them off. I bought high end gear because I can trust them to work, and that they do...

This is the best explanation I have read about the use of Hi-Tech DSLR's...Thank you!
We buy these because of the features they offer...

When I shoot sports I set a shutter speed high enough to stop the action, but I try to get a small enough aperture to show the context - a "star" means nothing if s/he isn't bettering opponents.

When using centre-weighted metering, with the main subject pretty well filling the frame, any mode will work about the same. If the lighting is changing much, I use either aperture or shutter priority mode. I have not tried using auto-ISO.
I prefer manual mode for those scenes where my metering point may not read the critical-exposure areas after composing. I prefer spot metering here.
I shoot film occasionally to keep my two manual-only reflex cameras in working order, so have no problems with shooting anything in manual with a DSLR.

So for subject isolation do you use manual or Aperature setting with your f/2 lens?
I'm more interested in indoor sports & portrait shots. I have been trying to stick with manual just so I'm aware of my settings. I'm still learning & thought learning manual would help me learn from my mistakes plus be more actively aware. Lightroom has been helpful too.

I cannot add much to what's been said above. If the lighting is even, the mode doesn't matter too much. I will say that for sports I keep my shutter speeds fairly slow and pan the players to show some motion and avoid having them and the ball looking as if they're frozen in mid-air. I also like the shallow depth of field of a 200 f/2.0, and usually shoot manual for both sports and portraiture (can't afford a 300 f/2.0!).

Stu, for me it is all about what I am shooting. If I am shooting sports of my grandchildren, I shoot in Shutter Priority to stop-action. But I'm mostly a landscape guy and trees don't usually jump around all that much. Then I set the F/stop and let Mr. Nikon choose a stepless SS.

These days photographers seem to focus on "subject isolation", so they intentionally spend "extra" for lenses with very wide apertures, and then they get their money's worth by using these lenses at/near their widest aperture.


Subject isolation is what my sports customers want. I spend money on wide aperture lenses to accomplish this not to please my ego. Do a survey of good sports photos and you will see what I mean.

I never said anything about ego; if that's what they want, that is fine. I'm an amateur, so I take what I want to take.

I'm not sure how to define "good sports photos"; I do know that I noticed deep DoF on "Final Four" pictures posted at MSNBC.

Same here. I'll use Av mode with the largest aperture to isolate the subject and will use the EC dial on top of my camera to tweak, if time and circumstances allow.

I use aperature for "dof" and to sharpen the lens.

Also using A mode gives you many more shutter speeds


Right! So many more choices than aperture gives you.

Just FYI—it is never advisable to shoot HDR brackets at different apertures, since the varying DOF creates a very strange effect when blended—a kind of ghosting. Better to let the ghosting be in moving water than in static objects.

Aperature control allows you to maximize dof in your photo. Shutter control is used in action shots. Any other time you want control of what is in focus. This is particularly true in group photos.

I shoot mostly in manual mode, occasionally in shutter speed mode, but would only use aperture priority when doing desktop shots or close-ups. As the largest Killer of most images we take is “blurred” photos and not lack of DOF, why use Av most or all of the time? Shutter speed priority keeps your speed from getting into the “blurred” area without knowing it when shooting other than Landscapes. At medium and long distances, usually your DOF is not an issue. I travel internationally 3 or 4 times a year for enjoyment and take tons of photos and can’t think of any time I need to control my shoots with an Av mode setting. Hope someone can enlighten me. Thanks in advance...

I guess I don't have a set rule of Aperture or Shutter priority. I generally use P for most snapshots. If DOF is critical then Aperture priority. If action is anticipated then I use Shutter priority. I set the camera so that once it uses up the aperture range it automatically slows down the shutter at that point. Works well for the way I shoot.
I would never limit myself to one method. I use manual when called for or one of my 3 preprogrammed C settings. Mindlessly limiting oneself to one option on a camera with so many options to be creative is ... well.... mindless. Same for AF.
