A new Tamron patent, JP2026-129519, hast recently come to light, detailing an ambitious ultra-telephoto zoom lens with a 12x range: a 50-600mm F4.5-7.3 VC. This design is explicitly for full-frame mirrorless camera systems, making it a highly plausible and exciting possibility for Sony E-mount shooters.
The core specs outlined in the patent include:
The optical diagrams within the patent reveal a multi-group design that incorporates special glass elements, which are typical in Tamron’s high-performance lenses to manage chromatic and other aberrations across such a large zoom range. This includes a focusing group designed for quick and quiet operation, which would pair well with modern autofocus systems. The VC system’s presence is a major feature, providing essential stabilization that complements any in-body stabilization.
Given Tamron’s extensive and highly successful line of lenses for Sony E-mount, this patent is a strong indicator of a potential future product for the system. It would create a unique offering, bridging a wide range of shooting scenarios from standard telephoto to extreme ultra-telephoto in a single, likely manageably sized lens.
While this is an intriguing patent, it’s important to remember that not all patented designs enter production. However, it demonstrates Tamron’s innovative approach to telephoto lens design and suggests an exciting new option for full-frame mirrorless users could be on the horizon. We will be closely monitoring for any further news.
