Re: And lots of TCs are just plain bad

I do remember there were a few pretty poor ones bouncing around.  The ones made by the cheap Chinese 3rd party companies were particularly bad - usually called 'Sakar' or 'Crystal Optics' - I think they're even still around new.  Also, some like your Canon one might have been originally intended as camcorder addons, where the resolution was so much lower that the lower quality didn't matter - I know some of the smaller diameter Sony ones you see around from the Camcorder line were similar - cheap, two elements, no coatings.  Definitely best to stick to the ones designed to go on the superzoom cameras at least - most were 1.7x - Panasonic, Olympus, Sony, Raynox, and I think Canon made versions like this.  I think Nikon had one too.
