Best WA for NEX-F3 in Antarctica/Patagonia?

Here's a few options:

1.  Try the new Sony SEL1018 lens ($$$)

2.  Try a good fisheye lens or Sony converter  - I use the Rokinon (Samyang) 8mm

The fisheye  image can be "de-fished" with software like DxO, PTGui, Fisheye-hemi (www.imagetrendsinc.com/products/prodpage_hemi.asp)

3.  Try the F3's "sweep panorama" mode -(best in portrait position) - Works with fisheyes too!

4.  Or better yet - get a Panosaurus tripod head (http://gregwired.com/pano/Pano.htm) and PTgui or other panoramic stitching program.

Have fun on your trip.  Perhaps you will need some anti-fogging lens solution?
