Rumor framing only. Sony has not published these lenses. Rumor-site coverage (Sony Alpha Rumors and aggregators) positions two sub-1 kg GM tele primes as a lightweight answer to Nikon’s Z 400mm f/4.5 and Z 600mm f/6.3 — “world’s lightest” class claims plus rumored pricing that is still unverified. Primary SAR posts are thin on use-case prose; the through-line is weight/portability and Nikkor parity. A tester note implies overlap with portable-tele users of the existing 300mm GM. The third piece is a specialty FE 8-14mm f/3.5 G fisheye zoom (G, not GM); coverage claims a first native FE fisheye zoom versus today’s first-party path often cited as a 16 mm converter on FE 28/2 — treat that as a coverage claim, not Sony. Sources do not say these replace the faster, heavier FE 400mm f/2.8 GM OSS or FE 600mm f/4 GM OSS.

Unconfirmed trio: two sub-1 kg GM teles and a G fisheye zoom. Sony has not announced these. All prices and weights below are leak/rumor — not official MSRP.
Rumor page, published September 8, 2026, before Sony announced these lenses. The product images are Sony’s official images from the later announcements; see our 400/600 GM and 8-14 Fisheye G coverage.
HIGHLIGHTS
Rumor desk — the trio
What rumor desks are bundling for a same-cycle announce (SAR “trusted source” timing around Sep 8 ~15:00 London, with preorders in the same window — still not Sony press):
- FE 400mm f/4.5 GM OSS — leak size/weight ~108 × 242 mm · ~994 g (SAR compare: ~14% lighter than Z 400/4.5 ~1160 g)
- FE 600mm f/6.3 GM OSS — leak size/weight ~108 × 263 mm · ~995 g (SAR compare: ~28% lighter than Z 600/6.3 ~1390 g)
- FE 8-14mm f/3.5 G — fisheye zoom; G badge (not GM); leak frames described with 8/11/14 marks, aperture + A, focus-hold, AF/MF, bulbous front; “Reframe Reality” teaser copy seen on unofficial frames
Tester soft notes (SAR): look similar to the 300mm GM; no rear drop-in filter; described as “affordable.” Optics formula, AF system detail, weather sealing, and teleconverter support are not in the leaks — omitted here rather than invented.

Every dollar, euro, and gram above is labeled leak/rumor. If Sony posts official numbers later the same day, this page needs a new official pack — do not silently upgrade rumor $ to MSRP.
Price / availability (rumor only). US and EU figures above are from rumor aggregators; SAR has flagged US $ as possibly “too good.” No retailer SKUs, no official ship dates.
Verdict
Pros
- If real, sub-1 kg 400/4.5 and 600/6.3 GM primes would fill a portable tier beside the faster GMs
- 8-14 G would be a specialty native FE fisheye zoom — if the leak holds
Cons
- Sony is silent; SAR “Confirmed” = trusted-source date claim, not a press release
- Rumor $ may be wholesale-skewed; no optics/AF/weather/TC detail in leaks
Further discussion
Related (different family). APERTURE NOTES’s Sony FE 100-400mm F5.6-8 OSS is an unrelated F5.6-8 zoom — not prior coverage of this GM/G trio and not a follow-up target.
