Sony has already had a busy 2026, but new reports suggest more lenses are in the pipeline. Engineering prototypes reportedly in testing include an 8‑15mm fisheye zoom, a 600mm f/6.3, a 400mm f/4.5, plus compact 28mm G and 40mm f/1.8 G primes. Alongside these, the FE 16‑28mm f/2 GM is still expected later this year.
8‑15mm Fisheye Zoom
A fisheye zoom would be a first for Sony’s full‑frame lineup, covering both circular and diagonal fisheye perspectives. Canon has offered one for years, and Sony’s entry would fill a creative gap for landscape, astro, and experimental shooters.
600mm f/6.3 Super‑Telephoto
The rumored 600mm f/6.3 prime suggests a lighter, more affordable option compared to Sony’s flagship 600mm f/4 GM. Positioned alongside the FE 100‑400mm F5.6‑8 OSS, it would extend Sony’s push toward accessible long‑reach lenses for wildlife and sports photographers.
400mm f/4.5 Prime
A 400mm f/4.5 would complement Sony’s existing 400mm f/2.8 GM, offering enthusiasts a more affordable alternative. Nikon has already taken this approach, and Sony’s rumored version would broaden options for E‑mount shooters.
Compact G Primes
The 28mm G and 40mm f/1.8 G would expand Sony’s compact prime lineup. The 40mm f/1.8 would sit above the existing f/2.5 version, offering faster aperture performance while maintaining portability.
Rumor Recap
Engineering prototypes often change or never ship, but the consistency of these reports aligns with Sony’s recent strategy of diversifying its lens lineup. If even half of these lenses reach market, E‑mount users will see one of the strongest expansion periods in years.

Summary
Sony is rumored to be testing several new lenses, including an 8‑15mm fisheye zoom, a 600mm f/6.3, a 400mm f/4.5, and compact 28mm G and 40mm f/1.8 G primes. Alongside these, the FE 16‑28mm f/2 GM is still expected later this year. While engineering prototypes often change or never ship, the breadth of focal lengths suggests Sony is preparing one of its most diverse E‑mount expansions yet, spanning creative fisheye options, accessible super‑telephoto primes, and compact everyday lenses. For enthusiasts and professionals alike, even partial realization of this roadmap would mark a strong period for the Sony ecosystem.
