SUMMARY
Tamron, known for its unconventional lens focal ranges like the 35-150mm and 20-40mm, has filed a patent for a new 50-130mm f/2.8 lens. This design features internal focusing and 17 elements in 7 groups. If produced, the lens could be highly useful for portrait photography, offering flexibility from full-length shots to tight close-ups, and potentially doubling as a macro tool if it includes a high magnification factor.
