Myth #1: The only difference between professional sports photographers and myself is $15,000 worth of equipment.
Busted: All of these photos are taken with a K-30 and a DA 18-135 DC WR lens. Knock a zero off of $15,000 and you still have about $300 left for another lens. What I don't have is the timing sense and sharp eye to properly frame interesting pictures and anticipate when to press the shutter button while the game is in progress. And I don't have press credentials to take my equipment courtside at events that publishers will pay money for pictures from.
Myth #2: You need a fast f2.8 telephoto to get a shallow enough depth of field to isolate a single player.
Busted: The picture above is taken at f5.6. My camera managed to get the ball in focus, but not the player getting ready to receive the pass.
Myth #3: You need at least 1/500 of a second to avoid motion blur.
Busted: This picture was taken at 1/160 of a second. Gravity prevents the basket netting from staying in that position very long.
Myth #4: You will have too much noise if you go higher than ISO 1600 with an crop sensor camera.
Busted: This picture was taken at ISO 12,800. Yes, I used Topaz Denoise at a moderate setting to clean up this picture, but the real problem is that the AF locked onto the black metal railing up in the stands. This high school gymnasium has lighting from the sixties, so I also had to set the white balance, but the colours you see now are true (and the people in the stands are underexposed because they are close to the ceiling and there are no lights up there).
Myth #5: You need telephoto lenses with lots of reach if you want to get shots of action at other end of the court/field/pitch.
Busted: With an APS-C camera, 135mm focal length is enough to go the full length of a basketball court. The DA 18-135 allows me to get the equivalent focal lengths of someone using a full frame camera and a 70-200mm zoom. I was standing on the floor, not up in the bleachers, but it's hard to convey action and movement in pictures taken from well above the game. Which is why getting field level access is so important.
This was my first attempt to shoot indoor sports with a DSLR camera. The biggest challenges are determining in advance what focal length you want for different areas of the court, anticipating where and when players will be in a good position for good pictures and keeping up with the game while you are looking through the viewfinder. Getting the right spot in focus is also a big problem, but with practice if I can get what I want in the middle of the frame, the camera should be able to figure out the rest.
