official · Pentax 6x7 specifications: Photoethnography.com Classic Camera DB, "Technical Details" table (secondary compilation citing period technical specs, NOT a directly-sighted original Pentax manual page — the original manual PDFs at butkus.org/cameramanuals.org are scanned images with no extractable/OCR'd text, so this could not be independently verified against the primary document) · accessed 2026-07-10
“Dimensions and weight: 177x101x91mm 1.29kg w/o finder; 177x152x91mm 1.76kg w/ TTL finder [row for "6x7" model, 1969]”

Pentax 6x7 dimensions carry medium confidence (archived-source caveat on its fit page).

Spec values are the manufacturers' published figures, compared factually — we don't rank cameras. Fit verdicts are planning estimates from published interior dimensions, not guarantees. See methodology.
