My main reason for buying into M3/4 was to get more hands on with photography and to get better pictures while traveling and backpacking, all in a small and lightweight package. I normally travel very light, with no checked baggage. Just a school size backpack for clothes and a satchel of some sorts for stuff that I always like to have on me (kindle, travel book, journal, pens, pipe and tobacco pouch). I’m interested in a longer focal length lens or two… I feel the 45-200 is too large for casual carry, but might give it a try at the Sapporo Ice Festival. Would the 45mm Macro be a good answer, or stealing some Nikon lenses from my friends, like a 50mm/1.4 maybe? Currently I travel with: GF1 – 6 months so far, and I love it. Panny 20mm – Fast, and my general use lens. Panny 14mm – Just picked it up, So Small! May replace the 9-18 with it… Oly 9-18mm – Nice and wide for landscapes, buildings, and interiors Panny LVF1 - Not sure if I'll keep this with me all the time Hoya Filters – NDx8, PL-CIR, and UV for both filter sizes I use. (Do I really need?) Gorillapod SLR – Nice, but I only really use it for the rare night shots. Lowepro Adventura Ultra Zoom 100 – Holds GF1 with 9-18, 2 extra memory cards, 2 46mm filters, the 20 and 14 pancakes in the bottom and a lenspen.; or with a pancake on the GF1 and an extra battery instead of the 9-18. Panny LVF1 on the strap. What will probably stay at home: Panny 45-200mm – Too big to travel with? Haven’t played with it much yet. Oly FL-35R – Slow recharge, and too big to travel with Billingham Hadley small bag – Holds entire kit, but not a good bag for my other stuff while traveling if I take all the camera gear I don’t travel with out. Might end up selling it.
