I'm probably not the first, but I just realized that interchangable lenses
used to make a lot of sense (one body, lots of lenses) but today they are unnecessary. I've picked up a number of great Pentax film bodies while acquiring lenses and just realized that if I put some light seals in 'em they can
each have a
different dedicated lens on 'em.
I just bought a big hard Samsonite suitcase, in good condition, at a thrift store for $1.67 and a big roll of foam from Hobby Lobby and I'm going to put my Spotmeter V and all my film cameras in it with a different lens on each one. (I'm planning on shooting mostly B&W and doing my own processing). Throw that big baby in the back seat of the car and off I go.
