In the item descriptions, they both say basically the same thing to me.

runninmann what the heck do I know?  More info | Jan 23, 2007 08:30 | #3 1.5X is older design. It consists of 5 elements in 4 groups without multicoating, weighs slightly less.

Also, I believe the diameter of the lens elements is slightly greater so you would get less light fall off in the corners when shooting with large aperture lenses.

I returned it for a 1.4, which has worked fine since then. I don't know if it was a bad unit or if it's a common problem with the 1.5's. Cody Goddard
