My experience with the Tokina 10-17 and the little Zen dome have suggested to me that I get better image quality with that combo than if using my large acrylic fisheye port. Lots of variables, but I'm not sure I'd cast off the little domes so quickly.
Hi Steve,
Is your acrylic fisheye port realy 180 deg. and your lens perfectly alighned in it, so that light rays really pass through the glass under the right angle?
