I was in Oslo last July and traveled north via plane and boat to Lofoton Islands (highly recommended) with a Leica MP, Summilux 50, TriX. I didn't feel disadvantaged equipment wise at all. The light in Oslo is less harsh than NYC but compared to Munich don't know but when cloudy its still bright enough for sunglasses but not a shadow in sight. On sunny days it looks like 4pm most of the day. Going north the sun hardly rises high enough to see it. For a week I never saw it directly but it was light 24 hours. Lots of green in the mountains and Fjords and grey on the sea. Bergen Fjords and Northern regions are definitely medium format territory while Oslo is 35mm P&S territory.
