In reply to Sean Kelly:
Battery life is a consideration, the OMD is very poor with regards battery life, the camera needs to be versatile enough for landscapes but able to take action shots, upto relatively fast MTB shots.
I love taking pictures with prime lenses, but also realise having one lens I can take out for the day is probably going to result in more quality pictures than a bag full of primes.
photography will fall into
Take all the gear and tripod for specific photo day out.
Big camera and zoom in anticipation of potential good shots but primary reason is being out in the hills.
Olympus OMD 5 for travelling light or climbing is the primary reason for being out and photography is opportune.
