A great deal of my landscape photography is conducted on long backpacking trips into the mountains of Colorado. As such, in late 2016, I made a conscious and well-calculated decision after months of research and spreadsheet manipulation to switch from Nikon F-mount system to Sony FE-mount system. At the time, I was photographing with the "Nikon trinity" (Nikon 14-24 f/2.8, Nikon 24-70 f/2.8, Nikon 70-200 f/2.8) set-up and it was killing my legs and my back. A change needed to happen. I found myself leaving lenses home to save weight. I was regularly hitting 50-60 pounds in weight for my backpacking trips, and I really was tired of hauling that much weight up into the rugged Colorado mountains that I so greatly adore. I also have been known to carry all of my camera equipment up to the tops of Colorado's highest peaks (as documented here) and so a lighter set-up was surely something I could appreciate.
I won't spend a lot of time trying to convince you that pack weight is important; however, I will state a fact: the lighter your backpack, the further you can hike. The further you can hike the more you can see and photograph. It is truly as simple as that. For example, this past autumn, I backpacked to a remote location near Carbondale, Colorado to get a unique vantage of my favorite 14er, Capitol Peak. I came away with some absolutely stunning images after a very difficult hike into this remote ridgeline. This rigorous hike was so much more bearable with a lightweight kit.
Sure, I could have probably reduced my weight by switching to Nikon primes, but I was also really enamored by the Sony A7RII camera and sensor. I pondered switching to Fuji as well, but through meticulous research I realized that the Fuji system would not stand up to the rigorous requirements I have come to expect out of my gear for astrophotography and post-processing. Sure, the Fuji system is really good, but I just was not ready to compromise to an APS-C set-up. Can you create great images with the Fuji system? Absolutely. Are they as good as the Sony system? Not in my opinion.
Secondarily, I found that the Sony lens line-up had all of the right ingredients I was looking for - a nice wide-angle lens with amazing sunstars and useful for astrophotography work (Zeiss Loxia 21), a light-weight fast mid-range prime lens with fantastic astrophotography uses (Sony FE 55 f/1.8), and a lightweight versatile telephoto lens for backpacking (Sony FE 70-300). By switching to this set-up, I have effectively reduced my pack weight by 4.6 pounds, which is quite a lot if you start to think about how backpacking pack weight impacts your ability to go far and see more. You can see the results of the pairing of the Sony A7RII & Sony FE 55 f/1.8 below - a very light weight kit (2 pounds total) capable of photographing the night sky in fantastic detail. This shot was from the top of a remote mountain in Southwest Colorado, only reachable via a long backpacking trip, which was so much easier with a lightweight kit.
If you too are looking to reduce your pack weight for backpacking or hiking, consider using my Camera Gear Comparison and Selection Tool / Calculator. I will be updating it over time with more useful information and capabilities. I think it is incredibly useful for comparing kits or even identifying lighter set-ups in your current Canon or Nikon kits. I have added most of the Sony full-frame camera and lens line-up as well as the Nikon and Canon equivalents.

I hope you find the information and tool useful and therefore do help me out in that way.
The tool uses excel online so that you don't need any special software to use it. Enjoy!
