Rumor: Sony may unveil two new G Master super-telephoto primes and a G fisheye zoom for full-frame E-mount cameras on September 8.
SonyAlphaRumors reports, citing a source it considers reliable, that the Sony FE 400mm F4.5 GM OSS, FE 600mm F6.3 GM OSS and FE 8-14mm F3.5 G will be announced at around 3:00 p.m. London time, or 5:00 p.m. in Greece. According to the same unconfirmed report, preorders will open at that time.
If the details prove accurate, the announcement’s main significance will be the weight of the two super-telephoto primes, which are both said to remain below one kilogram. They would extend Sony’s recent move toward more portable options after the Sony FE 100-400mm F5.6-8 OSS, without replacing the company’s faster and more expensive professional 400mm F2.8 and 600mm F4 primes.
Sony FE 400mm F4.5 GM OSS: a rumored weight of 994g
The rumored Sony FE 400mm F4.5 GM OSS is said to measure 108 × 242mm and weigh 994g. Its F4.5 maximum aperture would place it between very fast professional super-telephoto primes and slower zoom alternatives.
For comparison, Nikon officially lists the NIKKOR Z 400mm F4.5 VR S at 1,160g without its tripod collar. If Sony’s rumored weight is correct, it would be 166g, or approximately 14.3%, lighter, despite being slightly larger in diameter and length.
Sony FE 600mm F6.3 GM OSS: almost the same weight as the 400mm
The report about the FE 600mm F6.3 GM OSS is even more unusual. The leak attributes a weight of 995g and dimensions of 108 × 263mm to the lens, just one gram more than the rumored 400mm.
Nikon officially lists the NIKKOR Z 600mm F6.3 VR S at 1,390g without its tripod collar. Based on the unconfirmed figures, the Sony would be 395g, or approximately 28.4%, lighter. The OSS designation suggests built-in optical stabilization, but no details have emerged about its effectiveness, the optical construction, the autofocus system or teleconverter compatibility.
An 8-14mm fisheye zoom with a constant F3.5 aperture
The third lens in the rumored trio is the FE 8-14mm F3.5 G, a specialized fisheye zoom with a constant maximum aperture. Its 8-14mm range would offer more framing flexibility than a fisheye prime while retaining the strongly curved projection associated with this lens category.
An unofficial image of the lens has already circulated, but Sony has not published visuals or technical specifications. The type of fisheye projection at each focal length, minimum focusing distance, weight and optical construction remain unknown.
The announcement remains unconfirmed
At the time of writing, Sony’s official European Press Centre had not published an announcement or product page for any of the three lenses. No related teaser or scheduled livestream had appeared on the official Sony | Camera Channel either.
The names, weights, dimensions, prices, announcement time and preorder timing therefore remain unconfirmed.
Availability and rumored pricing
The report places the possible announcement and the start of preorders on September 8 at around 5:00 p.m. in Greece. It lists the FE 400mm F4.5 GM OSS at $2,699–$2,899, the FE 600mm F6.3 GM OSS at about $3,800 and the FE 8-14mm F3.5 G at about $1,499.
Using the latest available daily European Central Bank reference rate before publication, dated September 4, 2026, when €1 equaled $1.1622, those figures convert to approximately €2,322.32–€2,494.41, €3,269.66 and €1,289.80 respectively. These are conversions of rumored figures, not official European or Greek retail prices.
More information is available in the original rumor report. Official details are expected from Sony if the announcement takes place.
What we think
If the figures are confirmed, the most important point will not be the focal lengths alone but Sony’s effort to keep two super-telephoto primes close to one kilogram. That could materially change how they are transported and used handheld for wildlife and sports. The leaked prices require greater caution, while the 8-14mm will ultimately be judged by its projection, edge quality and how its fisheye effect changes through the zoom range.
