Late night clean-ups do have rewards! Found an old super wide macro extender lying around. X.42 mounts on 58mm, just right for the new 28mm. , result . . . a super wide angle complete with spherical deformation on the edges for the right amount of effect ! I've been contemplating on getting the Canon EF-S 10-22mm. Looks like that might not be necessary for a while. I'll be taking this baby for a spin and hopefully get it really fired up on the Ambongdolan Boulders in a few days, 3 days and counting !
