I wonder if you are still using the Leaf/Hy6 combo?
And yes, I am still using my Leaf AFi7 paired with the Schneider 40, 80 and 180mm lenses. I am very happy with it, but hope that they (Leaf/Sinar/Franke & Heidecke?) will come out with a wider lens option soon, preferably with better corner performance than the current Schneider 40mm.
I have found the AFi7 to be the best camera for my requirements. (Ultimate image quality and resolution with regards to both sensor and lenses for those large canvas prints, relatively light weight, open file format, the view camera option, easy handling ++) I only wish it would handle like the Canon 1D range with regards to battery cold temperature tolerances, weather resistance, AF when needed etc, but then again one can not find all the best qualities packed into one camera solution as some attributes are mutually exclusive. With regards to the shortcominngs there are for outdoors applications, I have found ways to work around them.
For both trips my backup camera was a Canon 5D, mostly used for shots > 200mm. One example would be this one: http://www.pbase.com/rune_molnes/image/84907333
If I remember correctly this was shot with a 5D/EF 400mm f/5.6 combo
