Go large format

I think they kids get focal length and (roughly) aperture.

I'd like to do some things which are a little bit more advanced: for example, it'd be nice to put in an aperture with a different shape (cut out of a piece of paper), and see bokeh balls. Or one with two holes side-by-side. And then talk about PSF and code up something along those lines. Or that sort of thing.

Then you want something like an old Speed Graphic lens:

You remove the front and rear groups from the shutter by unscrewing them. Quick and easy. And for some variety the lens will focus with just the front group.

Any large-format lens in a Compur shutter will do fine.
