It is amazing how everyone is so helpful here. I should have joined the forum long time ago. I bought my Nikon D7100 last year just when it was released. Since then I have been struggling with my focus. Out of 3000 picture, mostly of my daughter who is super, super fast and active, only a handful are tack sharp. It is that bad. With her it is hard to acquire focus on first place. She is that fast. I tried Continuous but it doesn't seem to work. From what I understand C is for subjects moving either towards you or far from you. What if she is moving sporadically all over the place. Maybe I should use 3-D. I haven't tried this one. Also it looks like I have shaky hands. I tried holding my breath when pressing and releasing the shutter. Nothing seems to work. Can someone give me an idea what focus setting to use when photographing my daughter and also suggest a good article on which focus configurations in which situations.
Thank you very much.
Keep using either Auto-focus Auto or Auto-focus Continuous, either should be fine, with 21 focus points. Adjust these settings by pressing the AF/M button on the side of your camera body. It's located at about eight o'clock if you're looking at the backside of your camera. Press it and at the same time, turn the Sub-Command Wheel (the one on the front of your camera) until you see "d 21". Press that same button but this time use the main Command Wheel (the one on the back of your camera) to adjust between AF-A, AF-S and AF-C.
Set your cameras Mode Dial to "S", This is Shutter (Speed) Priority Mode.
Now go into your cameras menus, go into the Shooting Menu and drop down to "ISO Sensitivity Settings".
Set your ISO Sensitivity to "100".
Set ISO Sensitivity Control to "ON".
Set Maximum Sensitivity to "6400".
Set Minimum Shutter Speed to "Auto.
Press "OK" and exit the menus.
Now, what you're going to do is use the Command Wheel on your camera, that's the wheel on the back of the camera, to dial in a specific shutter speed, say 1/200 or 1/250. That should be enough shutter speed to get consistently sharp shots of the fastest kid on the planet. Half press your shutter button, look at your top mounted LCD and spin that wheel until you see a shutter speed of 1/200 or 1/250. You want to use the lowest ISO that gives you proper exposure but Auto ISO is on, so the camera will manage that for you automatically.
With these settings, you should be good to go.
