Sony has reportedly made a significant offer to buy Tamron, a leading Japanese lens manufacturer that makes more than 20 lenses for Sony E-mount mirrorless cameras. Tamron’s Value to SonyTamron makes many lenses for Sony E-mount mirrorless cameras, APS-C and full-frame alike, which affords Sony numerous benefits. If Sony bought Tamron, Sony could also significantly alter how Tamron approaches making lenses for Sony’s competitors, including potentially not making them at all. Nearly half of the photographic lenses Tamron makes are branded with another company’s name and logo. In the event Sony bought Tamron, Sony would have to measure the benefit of harming its competitors against profiting off of them.
