best wide angle lens for the G 5 ?

[whitedime]

Im looking at either the canon wide angle that is available or the raynox

please advise. im looking for a lens that wont diminish my light input and still take sharp photos. I had a cheapie fisheye on my g1 and it was garbage. purple fringing and hard to focus

IQ on the Raynox seems comparable to the Canon:

interesting. they seem to be about the same price also. says its lighter weight so thats a go for the raynox...

looks like they dont make the 52mm adapter anymore.. fantastic.
