Relatively cheap. Not sure what that means exactly but I am going to recommend two. You decide which is better for your budget.





50mm F/1.8 http://www.usa.canon.com/consumer/contro鈥?/a>





85mm f/1.8 http://www.usa.canon.com/consumer/contro鈥?/a>








Keep in mind that stop action photography requires higher shutter speeds. The above are fast primes, they have good intrinsic acuity and they can allow faster shutter speeds for a given light level.What kind of lens should i use on my cannon rebel xti for capturing crystal clear pictures of dog agility?
Any Canon lens can do that.





First you have to learn to follow the action by panning with the dog(s).


Next use a high enough shutter speed to ';freeze'; the action.





In the end it is the skills of the photographer that produces the excellent images, not the equipment.

While the title is ';... Not Your Camera';, it equally applies to lenses, at least ones made by the original manufacturer of your camera.
You might want to take a look at the Canon 50mm 1,8.





It's about $80 and a big improvement over the kit lens.
