The Ica Atom (53, horizontal) is an early 20th-century German folding plate camera in the horizontal 4.5×6 cm format. Ica was a Dresden-based manufacturer that became part of Zeiss Ikon in 1926, placing this model within the pre-merger Ica lineage.

UK auction hammer results for the Atom (53, horizontal) are thin and condition-dependent, with recorded sales ranging from £75 to £280 on a median of roughly £180. Because these are saleroom hammer prices rather than dealer retail, what the camera is worth to a collector today in 2026 can differ notably from what it sells for at auction, and clean, fully-working examples tend to command the upper end of that range.
