I knew you'd love it Rick - yes, that one sure has done the rounds
Just watch really large sensors with them, as they do get eggy at the edge of APS-C and beyond. The new flattener for them does the trick (a flattener for a flatfield is fun, but when you consider the image circle...) but it is an expensive flattener. With my APS-C sized M26C, I'd get VERY slight eggs that I cropped out.
Enjoy it!
Oh, yeah, nice spider!
