And a button to take pictures

The Olympus OM Zuiko Auto-S 50mm f1

Unsure what makes this "Tri": There's a top compartment (measuring approximately 14x14x24cm) and a bottom compartment (about 15x22x26cm) but I'd assume a third compartment to complete the count

There's a standard 3/8" thread in the base for tripod mounting

so you'll need to guess your exposures (or use an external light meter)

Fujinon-C 450mm f12.5 corrective And a button to takeThe extremely compact Fujinon C 450mm f12. 5 covers up to 8x10, which is impressive for its size. Not the fastest lens in the world, but it's sharp, and it weighs less than 300g. Supplied in an accurate Copal 1 shutter with retaining ring; original box is included, too.
