I love seeing the shots of Marin. It's been 35 years since I lived in San Rafael.
I also am a big fan of the 24mm f2.8 AiS. The 20mm isn't as crisp in the corners, and the 24 gives nearly as wide a FoV (84 vs 94 degrees).
I have started experimenting with focus stacking in landscapes. I discovered that 1) with even slight focus breathing, you lose quite a bit of the image at the edges, and 2) that you need more images focused closely than those focused farther away (of course!). The following two images are each actually three images combined. Note the outrageous corner sharpness! More evidence that good photography has mostly to do with technique above all else.
Auger Falls is really challenging for me to get there and back safely with my gear. It takes me a few days just for my body to recover. And there are always lots of practical difficulties (such as not being able to drop anything (guess why). But now I can't wait to go back to apply what I've just learned!
