New to photography. Looking around and trying to figure out pro's / con's of mirror vs mirrorless for a non-professional photographer. Specifically, looking for something to take outdoor pictures. Something I can pack around and not need to worry excessively regarding use/abuse/dust/humidity. Thinking I want 70-200mm lens. And then either a doubler, or 400-600mm zoom. The kit that Big Sky just sold seems like it would have been a good set up to get started...

Thoughts for a duffer that likes to tinker ?
