Does anyone have a specific setting for Sports Bokeh?

I been trying my best to capture some Sports Brokeh but have ntot been successful at it.

For sports i been using AI Servo.... Manual, ISO ranging from 100 to 600, with no Success.... but i only own the Kit lens that came with my 40D 28-135...

"Bokeh" typically refers to the smooth blur in the out of focus background of a photo with narrow depth of field.

To get the best background blur, use the widest aperture available, i.e. the lowest Av f/stop your lens can provide.

On the 28-135mm lens, the widest aperture is f/3.5 at 28mm and f/5.6 when zoomed to 135mm.

So use Av mode and set to the lowest aperture value available... with sports, the added advantage is that wide open f/stop also gives fastest shutter speeds.

But that kit lens, especially when zoomed, isn't very fast (f/5.6 aperture), so don't expect the beautiful bokeh blur that you see from fast f/1.8 and f/2.8 lenses.

1) Get as close to the subject as possible (frame tight)
2) Add as much separation between subject and background as possible
3) Use widest aperture availalbe
4) use longest focal length available

You forgot #5. Buy 300 2.8 :)

Seriously as Matt pointed out even with great glass you have to seperate the subject from the background a bit. This was shot cross field with the 300 2.8. As you can see the subject is far away and even worst the parents are right there in the focal plane.

Even with a very distracting background of telephone poles, wires and a parking lot full of cars it disappears with your subject filling the frame.

You will be handicapped a bit with that lends but you still can make them look good.

Bokeh works in it's mysterious ways...

and I know a member will post the workz of Bokeh (something about the hyperfocal distance)

Already great advice on here, I guess the only key for you at this stage with that lens would be keep the apeture wide open ie lowest f/number you can achieve.

This was shoot at with my 70-200 at 200mm, ISO 400 f/4 at 1/500th cloudy dull day, should have used a bit if fill flash.
Focus was on the rear rider.

nice shot, was that shot with eh 70-300 f4?

Hope you don't mind, but i took your photos and did some Level Changes (to make the blacks look "blacker") and added10% saturation to give the color some POP....
