How to combine light sport and photography ?

Right now, I use the E-620.

In winter, backcountry ski, I use it with 14-42. If it is an easy trip, I also take the 40-150 to take pictures of people skiing down.

In summer, for mountain walk or trekking (no climbing), I use the 12-60 + 40-150.

I always have a small plastic bag so that I can protect the camera inside his wallet
from condensation when there are large temperature changes or rains.

All is a matter of weight. A M43 with 12-50 is very appealing for my use, especially the EM-5 with weather protection.
