The quality of the Canon RF 24-105/4L makes the photo looks like it was shot with an iPhone. You have been making some very nice artistic images lately (log dam in particular). You should always have the Zeiss Loxia 25/2.4 handy so that you will have some technically brilliant photos after all that hiking and physical effort.
DIGLLOYD: that's not quite fair—the Canon EOS R sensor is good for what it is (30MP) and looks good at ISO 100. But I’ll be damned if I’ll carry a camera that far and hard to get 30MP instead of 45MP, particularly with a dud lens.
Unfortunately I injured my knee badly by carrying a too-heavy pack with Canon EOS R and Nikon Z7 kits with various Zeiss Otus and Zeiss Milvus lenses ~12 miles that day, including up one steep and loose slope to Bear Lake where I think I mildly tweaked my left knee. No particular incident, just a slight tweak followed by a nagging irritation followed by over discomfort. By 9 PM when I finally reached my Mercedes Sprinter I was limping and the knee was swollen up badly. I am really bummed as I won’t be able to hike my favorite places for a good while probably (I’d be thrilled if it were only a 2-week downtime) as while the knee swelling has come down (prednisone accelerated that), it is still crunchy.
My points are twofold: (a) I am always evaluating new gear and there was no room for the Sony A7R III on that hike, and (2) I bit off more than I could chew: bad planning on timing as it was a 10.5 hour hike and I carried gear I didn’t have time to put to use (the Milvus and Otus and ZF.2 and ZE lenses). In the future, I’m going to take along the compact hanging scale I have in my garage for weighing bikes and such, and keep it in my van so I can hang and weigh my pack, and thus limit myself to a predetermined weight in order to cut the risk of such injuries down.
This series evaluates performance of the Zeiss Otus 55mm f/1.4 APO-Distagon on a distance scene from f/1.4 through f/6.3. In dim flat light, 'penetrating power' is needed to deliver good contrast and micro contrast; the light here was very flat and diffuse.
Shot on the Nikon Z7 using the Nikon FTZ lens adapter. The Nikon Z7 has an ultra-thin sensor cover glass 1.1mm thick that may impact the imaging performance versus the Nikon D850 (~2.0 mm thick).
