Hi, new to this forum.

Looking for some advice regarding travelling to Scandinavia.

Locations: Sweden, Finland, Norway
Time: Early-Mid June
Camera Model: Canon 600D

1. What are some recommended lens to bring?
2. What other accessories do I need? Filters? Bulb release? Flash? Lens Hood? (I haven't bought any accessories yet, recently upgraded from a spoilt G10)
3. What kind of photographic opportunities are there besides landscape? Macro? Long Exposure (it's mostly daylight though...)?
4. What are some recommended places (Although I'm travelling with tour group...)

Appreciate any other tips!
