  For those who might be considering doing this, don’t unless you’re ok with destroying the camera.

    How does it destroy the camera?
    • IAmGraydon 3y ago
      Most DSLRs are designed to withstand down to 0C. Most freezers are around -20C. You risk damage to the battery, condensation on interior components, contraction and mechanical damage of components with tight tolerances, etc.
