Best for
A Bronica SQ system accessory - swaps onto Bronica SQ bodies in place of the standard 6x6 back. The 6x4.5 format gives you 15 exposures per roll of 120 (vs 12 for 6x6) and a rectangular aspect ratio closer to 35mm. Useful as a secondary back for deliberate aspect-ratio choice mid-roll.
Frequently asked questions
Why would I want a 6x4.5 back instead of 6x6?
Two reasons: more exposures per roll (15 vs 12), and a different aspect ratio (roughly 4:3 vs square 1:1) that's closer to traditional print proportions. Useful for situations where you want more frames, or naturally rectangular compositions.
