Hey weinelm, this converter lens is just as good as any other wide angle lens. It performs really well across the frame at all apertures and is sharp. RICOH have always made great lenses like this that perform really well with they're cameras.
No vignette was applied in this scene, it's just the look of the sky...
Although, there is a very very very slight vignette added to a scene when the 'Ambient Brightness' mode is set to 'Original'.
Anyway, this mode sure does correct the 'concentric ring artifact' issue. You can now pull-process an underexposed scene to your heart's content and not have any worries that this will occur, even in RAW files...we can now turn 'night into day' and not see any 'rings'.

Its a failing of the forum John, that you cannot edit links. If a link gets broken on the Talkxxxxxxphy forum, I can simply go back into my OP and amend the links to the pic
