JoJu,
it's pretty interesting. I don't plan to buy stuff this year, anyway a UWA with 1:1 is interesting indeed. You can do neat stuff with flowers and insects.
The use of extension rings is difficult if not impossible with UWAs because they need to be very thin. For instance, I've experimented with the Samyang 8mm fish-eye and the required extension is less than 1mm. I ended up by buying a second lens and using the older one for experimenting: I inserted a cardboard spacer under the lens mount.
Things improved when I switched to the Sony mirrorless - I could buy a Nikon-F/Sony-E mount adapter which includes a focusing helicoid, which means I can use the unmodified Samyang and return to normality with infinite focusing without changing lens. The problem is that the DoF is so thin that focusing is a hard job (especially when you have some wind moving the flowers).
Having 1:1 in a normal lens preserving infinity focus is interesting. It all depends on sharpness and effective angle of view. Looking forward to see your photos. :-)
