The samples I have seen at dpreview.com show slight vignetting. But the Tiffen kit is great value for money - 2x zoom, .5x wideangle, adapter, stepdown ring and case for (I think) $130. Sadly only available in the US! Lots of discssion of this at dpreview.
I believe the Tiffen thread is 43mm, so a step-down ring would be required with the Lersmate or Canon adaptors. Question: would the vignetting be caused by the step-down?
regards,
Paul

Just learned that Tiffen will be introducing a new line of lenses including the 2x Telephoto in ~2 weeks (~May 15).
It will be far more improved over current models. Supposedly no distortion, vignetting, etc.
List price: $ 99.95
Size: 43mm
They will also have a $20 adapter at that time for it.
Haven't found out yet what will be needed for adapting to Lensmate.
