Holga Ewe ∞
I just received a Holga pinhole lens in the mail. It's very inexpensive, made of plastic, and endowed with (un)limited utility.
Pasture Photography c. 1850
As long as the nature holds very still, you're all set. I have recently been in touch with Gary Hall, a Vermont landscape photographer who works entirely with medium or large format film cameras, printing and framing his photographs as big squares. My opinion is that this leads the eye to view the landscape in a particularly sculptural way, rather than as a panorama or a scroll.
