Samsung Tests Variable-Aperture Camera Modules as iPhone 18 Pro Is Expected to Add the Tech

Supplier sampling points to early testing driven by reports that Apple's iPhone 18 Pro will adopt the feature.

Overview

  • Korea’s ETNews reports Samsung has asked camera partners to develop variable-aperture components, with Samsung Electro-Mechanics and MCNEX producing samples for evaluation.
  • The work is described as early-stage with no final product decision, and multiple outlets say the upgrade is unlikely to appear on the upcoming Galaxy S26 lineup.
  • Some reports point to a later target window such as the Galaxy S27, reflecting a longer validation cycle before any flagship rollout.
  • Apple’s iPhone 18 Pro and Pro Max are widely expected, per analysts and leakers, to introduce a variable-aperture main camera later this year.
  • Variable aperture can improve low-light capture, manage highlights, and deliver true depth-of-field control; Samsung last offered a two-stop system on the Galaxy S9/S10 but dropped it over thickness and cost, which suppliers now say have improved.
