Very nicely done, Jason. Lovely photos, excellent write up.
I think many people simply need to do as you've done: accept that the MM is a fine camera, that you're not going to be an expert using it overnight, and learn to use it properly. Too many of the reviews and comments I have read on this and other cameras seem to make the assumption that you can be an expert user of any new camera in a couple of moments. And if your results from the first or second walk about aren't perfect, the camera is at fault.
Nothing could be further from the truth in my experience. It takes time to learn and understand how a particular camera sees and what's required to realize what we want to with it. Same for each lens we use.
Keep going! I'll be following your posts and development with the MM. 🙂
