Here are the first few for your perusal. I have included a crop of about 80% I think.
I have to say so far I`m blown away with the 150-600mm Fuji and I`m not sure the 500mm f4 would have been any better and possibly not even as good, and I can`t believe I`m saying that.
These have been through De noise but not Gigapixel because these just about filled the frame anyway, but I think at St Aidens some of the far away stuff may need Gigapixeling. I am seriously thinking about whether I need the 500mm or not but further testing is needed before making the final descision.
