Today my son had another basketball game (outside on a very clear and sunny day). So, instead of just shooting a bunch more pictures of his game (I already have too many to count), I thought I would do some experimenting with Dynamic Area focusing and 3D tracking (11 point) focusing, neither of which I know hardly anything about.
The results I got are kind of confusing me. Most of the shots came out like so many others - pretty clear freeze action shots. But there were quite a few interesting motion shots, as well as some out of focus shots.
I also need to mention that I goofed. I was shooting in Priority aperture mode instead of Shutter aperture, so my shutter speeds vary from 1/30 to 1/250. I was also using my sun hood for the first time (because like I said it was a very sunny day, and the sun was very bright on a good part of the court).
So anyway, here are some of the results I got.
First of all in
Dynamic Area focus mode. Here are a couple of the interesting ones. Again, even though the shutter speed might cause some of this effect, I was really interested in how the camera handled the actual focusing:
F/22, 1/40, ISO 640
f/22, 1/50 ISO 640
and here is an example of an out of focus shot using this mode:
f/22, 1/100, ISO 640
I find it interesting that this shot actually had a faster shutter speed than most, yet it is out of focus, but the others aren't.
Now, here are a couple of examples using 3D tracking (11 point) mode:
f/22, 1/30, ISO 640
f/22, 1/50, ISO 640
Why, in this shot, is the boy in front (number 18) in focus, and the people in the background in focus, but the kids in the middle are out of focus?
and also an out of focus example of this mode:
f/22, 1/50, ISO 640
As you can see, both modes offer some interesting effects. Unfortunately I still don't really understand why they produced some of these shots, and why most of the shots came out looking a lot more "normal" (the freeze the action kind of shots).
I do want to do some more experimenting with these modes (and next time shoot in shutter priority, so I can get more consistent shutter speeds). But if anybody has any comments or suggestions about these 2 modes, I would love to hear them.
