That's kind of why I suggested the 9mm Body Cap Lens, it's 1.1oz and literally the size of a thick body cap. Is it anywhere near as good as a dedicated wide? No, but you can find them for $75-$80 so why not?If you are OK with stitching a panorama, I would skip the ultra-wide and instead stitch a few shots from the wide end of your standard lens. That will save you a few/lot of ounces, and space in your pack.
I was pleasantly surprised at how well the current software stitches images, compared to what I used before.
Coming down was kind of fun. What took at least 45 minutes for me to go up only took a few minutes to get down. Just dig in your heels and take steps, almost like skiing, unless you fall which for my luck I didn't. I just followed the lead of our guide and somehow was able to mimic his technique. It was a bit scary though having never done it before and I did feel it in my hip.Welcome back down to earth! Yeah, a trip full on amazing memories and accomplishments. Going up scree is so much easier, and way less scarier, than coming down a scree slope.
Thanks for the reply. My understanding from your OP was that you wanted something with similar quality to your D850. I would have thought that you might have landed on something more in the middle, like a 1" or m4/3rd's camera. In either event, I am glad your trip worked out for you.Frankly, my iPhone. This was not a hike/climb focused on photography, it was about the brother-ship and experience.
