Tamron’s financial results are always interesting thanks to the company’s candor in breaking down its own-brand versus OEM lens production and sales data. These OEM lens sales are down, with Tamron noting “continued weak orders for certain models — a trend persisting since 2H of the previous fiscal year.” During FY2025 1H, 45 percent of Tamron’s lens sales were OEM models, leaving 55 percent for its own branded optics. Unit sales of OEM lenses dipped 29.5 percent, and the value of these lenses dropped 10.3 percent. So far there have been two totally new Tamron lenses in 2026, the 35-100mm f/2.8 and the 12-20mm f/2.8.
