Perhaps it's apples to oranges, but if you were a Canon 5D owner, would you replace it with an X100S? I'm a semi-professional (or extreme hobbyist) photographer. I currently own a 5D and a solid range of high quality prime lenses. I really do love the camera, and it works very well for what I shoot - weddings, portraits, pets, nature, etc. But I'm also very enthusiastic about travel photography (which is what lead me towards making a part time job out of photography), and the 5D, with all its stuff, just isn't travel friendly. Big, bulky, basically a 30 lb backpack of stuff to carry around. I think I would enjoy the simplicity of a X100S, especially in terms of travel photography and street photography (where an X100 is much more discreet than a 5D). But would it be too extreme a transition? I'm okay with no longer doing weddings, and scaling back on portraits, pets, etc. But I wouldn't want to sacrifice on nature/landscapes, star trailing, etc. Thoughts?
