Well that was entertaining for sure. NY, do to your lack of posts along with lack of signature that shows us your "rig" I am going to have to agree with buck here on this one. You have nothing to backup anything you say, how can you possibly shoot 1/125 in A mode with NO tripod.. sorry one with a wobbly head. tis not the possibles.
I don't need to dangle my equipment to back up what I say. What I say either makes sense, or it doesn't. Or maybe it's close and a tweak or two gets it there.
But just to respond to YOUR brilliant statement, you don't set the shutter speed in A mode, you set the aperture, (and hopefully you make a reasonable choice or ISO, and the camera pick the shutter speed. And while I see you claim to have bought some camera equipment, I don't see a link to YOUR portfolio either. So to use your logic, you must be completely FOS as well?
Back to the original premise for the reading and/or attention impaired...
Also, when shooting sports, make sure you're at the max aperture. Always.
That usually means A (aperture priority) mode.
NYCphotography, I disagree and agree. Wide open ap is great for sports photography, however, if the shooter were to use A (aperture priority mode) he could possibly get super slow, awful shutter speeds and ruin the whole shoot. It would be better to work in S (shutter priority mode). Set a motion stopping shutter speed and let the aperture fall where it may. Zoom your telephoto lens and get depth of field with the zoom and not the aperture.
In that scenario, I'd meter the darkest shot I expect to encounter, and set the ISO so I'm shooting 1/125 at f2.8. That may mean 1600, 3200 or even 6400 ISO. Yes that may be noisy, but I can "remove noise (various filters) -> add blur -> downres -> sharpen" in post to fix that. It may also mean the addition of a monopod for camera stability. I find that high ISO works fine when you know you're going to downres for display. But I'd really have to be there in the venue in order to figure it out. What I think I'm going to do doesn't always work in the real world, so it's good to have a plan B or C.
I guess we both get to the same place, just each do it in our own way. And it's good to know all the ways possible.
Leaving the camera in A mode, setting the ISO per the meter reading of the DARKEST place in the gym, means that the SLOWEST shutter I'd use is 1/125. I'd expect to have 2-3 stops of variability between the darkest shot and the center of the court, so I'd expect to get a faster shutter most of the time.
But as the OP, with a 80-200 lens at f2.8, yes I would hope to get some usable shots. Maybe I'd be disappointed, but I think I'd get
some good ones. Would I get Sports Illustrated coverage of every second of the game with every razor sharp frame coming out perfect? Of course not. But I'm not shooting under NBA quality lighting, and I don't have that requirement (SI editor on my back) either. All I need, all I want, is a
couple decent shots of my kid playing basketball. I know I can get a couple decent shots at 1/125 on a 80-200 lens. I know it's possible.
And yes, I don't often use a tripod. Do you shoot sports on a tripod? I don't shoot much sports, it's not my thing. But the little I have done, the last thing I wanted was to be tied down with a tripod. My tripod got broken a few years ago because it always just sat in my car with all my other gear piled on top of it. By not using a tripod, you learn to have a fairly steady hand, btw. And you also learn what you can and can't "get away with" when the need arises.
So now I'll actually have go dig through my unprocessed files and find something I've shot that proves that it's possible. What a joke.
