Tamron
While a Tamron 90mm f/2.8 Di III VXD Macro for Sony E-mount is a speculative lens, it would build upon the legacy of Tamron's legendary 90mm macro lenses, updated for the mirrorless era. It would be designed for full-frame cameras, offering a true 1:1 magnification ratio for stunning, life-sized close-up photography. The f/2.8 aperture would provide a bright viewfinder image and beautiful background blur, isolating subjects effectively. A hypothetical modern design would incorporate Tamron's high-speed VXD (Voice-coil eXtreme-torque Drive) linear motor focus mechanism, ensuring silent, fast, and incredibly precise autofocus performance, suitable for both stills and video. This would be a significant advantage for macro work, where focus is critical, and also for portraiture, where the 90mm focal length excels. The optical formula would likely feature multiple special lens elements, such as LD (Low Dispersion) and aspherical elements, to combat chromatic aberrations and ensure outstanding sharpness and clarity from the center to the corners of the frame. It would also likely feature a moisture-resistant construction and a fluorine coating on the front element to repel water and oil, enhancing its durability for outdoor use. This lens would be a top choice for photographers specializing in macro, portrait, and still life photography, delivering the exceptional image quality and performance that Tamron is known for, in a package optimized for Sony's full-frame mirrorless system.
