Fascinating captain!
That Sigma really does like its capable of taking down a gunship.
The battleship from pinhole camera is my fave.
For anyone fancying the engorged dimensions of pano/mosaic photography, the Max Lyons forums are a good place to start. You'll have a lot of fun but not much life left.
I have to admit that I've been wondering about that Sigma lens in 4/3 mount... could you imagine it with a 2x magnification factor?
