If you know the optimal setting, panning techniques
can get better results. Here's one example
(with EF70-300mm f/4-5.6 IS USM):
1. Turn the IS function on and select IS Mode 2.
2. To improve your success, shoot at around 100-200mm
(rather than an extreme 300mm telephoto setting).
3. Select the camera Tv exposure mode and 1/60 sec.
shutter speed. Select AI Servo AF as the autofocus mode.
4. While keeping the moving subject in the viewfinder,
press the shutter button halfway down and hold.
5. Then, at the right moment, press the shutter button
all the way down to take the shot while continuing to follow the subject.
Keep using this technique while taking several photos.
Go ahead! Impress yourself with panning shots like a pro!
What's the best shutter speed?
Actually, there's no simple answer. The optimal shutter speed varies depending
on the amount of subject motion and other conditions. If the shutter speed is too
fast, images appear static and lacking in energy; if the shutter speed is too
slow, images may be completely blurred. Find the best shutter speed by trial
and error. Check results in the LCD monitor right after shooting and decide the
best shutter speed 'for yourself.
