Third-party lenses remain one of the biggest reasons Sony E-mount is the most flexible mirrorless ecosystem—and Tamron just provided a pretty direct roadmap for why that advantage likely grows in 2026.
In its FY2025 financial results materials, Tamron reported a down year financially, but the more interesting part for Sony shooters is the product strategy: Tamron says it’s accelerating own-brand launches to “10+” in FY2026, up from 6 launches in FY2025.
For the “Photographic Products” segment:
Tamron attributes the softness largely to photographic OEM shipments falling sharply (order reductions / market stagnation), while own-brand trends improved later in the year (turning to growth from Q3 and exceeding ¥10.0B in Q4 own-brand sales).
Tamron’s slide deck spells it out: Sony E-mount = 21 total models, which is still larger than Tamron’s current Z / X / RF offerings.
That matters because it suggests two things at once:
In the FY2026 forecast section for photographic products, Tamron says own-brand revenue is expected to grow driven by the launch of 10 new models (plus recovery in Europe/China). Elsewhere, the company frames it as: FY24: 7 launches → FY25: 6 launches → FY26: 10+ launches, and the updated plan raises the pace to 10 launches per year.
Note: Tamron often counts an existing lens released in a new mount as a “new model/launch,” so not all 10 will necessarily be brand-new optical designs.
If Tamron actually executes on 10 new models in FY2026, Sony shooters are likely to be some of the biggest beneficiaries—because Tamron’s own materials show E-mount is still the foundation of its mirrorless strategy.
