Hej Thomas,
Very interesting information indeed.

But isn't there a connection between grain and resolution? What do both

Well - normal shooting is not the challenge. It becomes interesting when
shooting in these high contrat situations, I think.

Same experience here.

Aaah - wha a bummer. I want to prevent taking two or more bodies with me to
Greenland next time. Carrying 20+ kg of backpack for 4 weeks is so back

No, I agree. As regards budget, when spending lots of money for travel tickets,
I'd rather add some bucks for the better film.
