I shoot with a Canon 5D mark 4 after upgrading from my previous 6D. My lenses are all high quality Canon L glass including Canon 35mm f1.4L, the stunning 70-200mm f2.8 II and the excellent and very sharp 16-35mm f4 for the wider shots. A most recent addition is the Canon 24mm tilt and shift lens which I believe will become my most used lens for wide angle stitched panoramas. I have other lens but these are my favourites. All my lenses deliver sharp and high resolution images across the frame.

In my rucksack you will also find various filters (Lee, polariser, ND, graduated ND etc), waterproofs, headtorch, batteries, maps (East/West maps are brilliant!), water, lunch and, of course, a heavy tripod. This all adds up to quiet a hefty weight to be carrying up and down mountains but hey, I need the exercise:)
