Auto Iris

Canon DSLR video lens?

I am looking to buy a zoom lens to use for my canon t2i but it can not have an auto iris bc i want to be able to zoom while taking video, hoping to be under 400 dollars. any suggestions? thanks!
I need a zoom lens, and I cant use the kit lens for video because of the auto iris, it flashes when i zoom so i cant record that bc the iris is adjusting…

Tamron 18-270 is a superzoom that runs $300ishesque. It has great optics too.
