I have used the Canon 3x WA lens and was pleased with the result. Another option, and much cheaper, would be to buy a Century Optics .6X wideangle adapter made for the XL-1. This adapter fits on the bayonet mount for the 16X's lens hood. The cost is about $370 and the optics are excellent. Another benefit is that you have a wideangle lens that has an image stabilizer. The Canon 3X lens does not have one. Either lens will make you happy. Good luck.(posted 9108 days ago)
