The original SX-70s had very nice optics; they are remarkably sophisticated cameras.

I like this idea about the distillation of composition, although I don't think it's a property unique to instant films. It reminds me of A. Adam's quote, about "sharp images of fuzzy concepts," where I've seen many sharp "test shots" on digital camera forums, whose resolution, tonal range and dynamic range are textbook state-of-the-art, but the image itself is, well, pedestrian. Another example is a well-made pinhole camera image that, although lacking in technical sophistication in virtually every metric measurable, somehow comes through the lo-res muck to reveal something essential. This kind of hidden art is not about the format or technique - it has nothing to do intrinsically with instant film's properties - but rather about how a person, skilled in photographic technique, can apply their inner artistic gifts and transcend the medium.
