Re: Anyone try a 1.4X extender with it?

I know the 1.4x extender has been used successfully on the sigma 10-20mm enabling it to go quite a bit wider than if it was just mounted straight onto the camera.

Wonder if it would work for the sigma 30mm. I don't see why not...

Why does an extender (TC) make a lens wider - shouldn't it be narrower?

That's what I thought too, but there is a thread on POTN that shows the sigma 10-20mm is actually wider with less vignetting when used with the extender.
