Walter uses a Polaroid Spectra to photograph Melvin alongside the "snake monster", a service he offers for the bargain price of just $3.
Rhonda uses Burt's Nikon F3HP with an MD-4 motor drive to photograph Valentine and Earl during the movie's conclusion. Based on the proportions, the integrated lens hood, and the four-wide focus grip, the lens is likely the Nikon Nikkor Ai-S 135mm f2.8.
