Title: Worth it.
Review: I was debating between the Kenko and this one but since I have Tamron lenses and went for this one instead. I was photographing the moon during New Year's eve with a Canon 5DII using LiveView and a Tamron 70-300vc lens (tripod, VC off, manual focusing) the picture came out surprisingly good with the exception of atmospheric haze, you can actually see the the haze distorting the image. This converter is designated for Full Frame lenses only (EF not EF-S)
