Sony has introduced two new G Master super-telephoto primes that make long-range photography more accessible to wildlife and sports photographers. The Sony super telephoto lens lineup now includes the FE 400mm F4.5 GM OSS and FE 600mm F6.3 GM OSS, offering impressive reach in lightweight bodies without the five-figure prices of Sony’s flagship lenses.
Sony’s new FE 400mm F4.5 GM OSS and FE 600mm F6.3 GM OSS bring a straightforward proposition: professional-oriented autofocus, optical stabilization, and long focal lengths in a compact design. The 400mm lens is aimed at photographers who need flexibility for wildlife and sports, while the 600mm model is designed for subjects that are harder to approach, including birds and distant animals.
The new lenses were announced on September 15, 2026, with US prices of $2,699.99 and $3,699.99, respectively. Their approximately one-kilogram weight makes them considerably more portable than Sony’s flagship 400mm F2.8 and 600mm F4 primes.
But lower prices and lighter bodies involve compromises. Maximum aperture, low-light performance, and background separation remain important differences. This Sony FE 400mm F4.5 GM OSS review and Sony FE 600mm F6.3 GM OSS review comparison examines the specifications, handling, autofocus, teleconverter options, and value to help photographers choose the right lens.
The Price Gap Is the Whole Story
The biggest selling point of Sony’s new super-telephoto lens pair is the price difference compared with the flagship alternatives.
Sony’s FE 400mm F2.8 GM OSS and FE 600mm F4 GM OSS are premium lenses designed for demanding professional photography. Their prices, around $12,000 and $13,000 in the original comparison, can make them difficult to justify for enthusiasts or photographers who do not regularly earn money from wildlife and sports work.
The FE 400mm F4.5 GM OSS is listed at $2,699.99, while the FE 600mm F6.3 GM OSS is priced at $3,699.99 in the US. These prices put the new lenses at a much more accessible level than the flagship models.
The 400mm is the more affordable option and offers a versatile focal length for larger wildlife, field sports, and subjects where the surrounding environment is part of the composition. The 600mm provides more native reach for distant subjects and smaller wildlife.
The lower price does not make either lens inexpensive. Both remain premium G Master products. However, they provide a more realistic entry point for photographers who need long focal lengths without investing in flagship glass.

Dissecting the Specs
Both Sony telephoto lenses are designed around portability and high-speed autofocus. The FE 400mm F4.5 GM OSS weighs approximately 994g, while the FE 600mm F6.3 GM OSS weighs approximately 995g, excluding the tripod mount.
The 400mm model measures approximately 108 × 242mm, and the 600mm measures 108 × 263mm. Their similar weight is particularly impressive considering the difference in focal length.
Sony’s optical design uses ED and Super ED elements to control chromatic aberration. Both lenses also feature Nano AR Coating II, an 11-blade circular diaphragm, and dual XD Linear Motors for autofocus.
Sony states that both lenses support AF/AE tracking at up to 120fps with compatible Alpha 9 III bodies. This capability is useful for photographers tracking fast-moving wildlife or sports subjects.

Handling and Portability
Weight is a major consideration for wildlife photography. Photographers may spend hours carrying equipment, tracking birds, or waiting for an animal to appear. A heavy lens can increase fatigue and make handheld shooting more challenging.
At approximately 994g and 995g, the new Sony lenses are designed to make super-telephoto photography more manageable. Sony has also optimized their balance to position the center of gravity closer to the camera body, improving control when tracking moving subjects.
Both lenses include customizable focus hold buttons, a function ring, and a focus range limiter. These controls allow photographers to configure the lenses according to their shooting style.
The dust- and moisture-resistant construction, along with the fluorine-coated front element, also supports outdoor use. However, Sony specifies that the lenses are not completely sealed against dust or water droplets, so photographers should still exercise care in difficult weather.
Not All That Glitters
The lower price and lighter design come with real compromises.
The FE 400mm F4.5 GM OSS and FE 600mm F6.3 GM OSS have slower maximum apertures than Sony’s flagship F2.8 and F4 alternatives. This affects the amount of light reaching the sensor, particularly in dim environments.
For wildlife photographers working at dawn, dusk, or under forest canopy, the difference can be significant. A faster aperture can help maintain lower ISO settings or faster shutter speeds, both of which are important when capturing moving animals.
The slower apertures also affect background separation. Although long focal lengths can still produce attractive subject isolation, the flagship lenses have an advantage when a photographer wants a very shallow depth of field.
The 600mm F6.3 is particularly demanding in low light. Adding a 2x teleconverter reduces its effective maximum aperture to approximately f/12.6. That combination can provide impressive reach, but it places greater demands on exposure and autofocus.
The optical designs also differ from the flagship lenses. The new models use a comparatively lean optical formula, while the more expensive primes have additional elements and faster apertures. Photographers should not assume that the cheaper lenses will deliver identical performance in every shooting condition.

What Works
- Significant price reduction compared with Sony’s flagship super-telephoto primes.
- Sub-kilogram weight for more manageable handheld shooting.
- 120fps AF/AE tracking support on compatible Alpha 9 III bodies.
- Teleconverter compatibility for extended focal-length reach.
- Dust- and moisture-resistant construction with a fluorine-coated front element.
- Carefully balanced design for tracking moving subjects.
What Doesn’t
- Slower apertures limit low-light performance compared with flagship lenses.
- Teleconverter combinations reduce light gathering and can make autofocus more demanding.
- The lower-cost optical design may not match the flagship lenses in every condition.
- Both lenses remain expensive purchases for casual photographers.
- Neither offers zoom flexibility, requiring photographers to choose their focal length before shooting.
Sony 400mm GM vs 600mm GM for Wildlife
Choosing between the two lenses depends largely on the subjects you photograph and how close you can get to them.
The FE 400mm F4.5 GM OSS is a versatile choice for larger wildlife, sports, and subjects where including some background context is important. Its 400mm focal length can provide a balanced perspective, while the f/4.5 aperture offers a modest light-gathering advantage over the 600mm.
The FE 600mm F6.3 GM OSS is better suited to smaller or more distant subjects. Bird photographers, in particular, may appreciate the additional reach when they cannot approach their subject closely. Its longer focal length can help fill more of the frame without relying as heavily on cropping.
The 600mm lens also supports a 2x teleconverter, extending the focal length to 1200mm. That is an impressive option for distant subjects, although the effective aperture becomes significantly slower.
For photographers who frequently shoot in low light, the 400mm may be the more flexible choice. For bird photography and distant wildlife, the 600mm can be more useful.
Independent reviews also provide useful real-world context. Amateur Photographer’s FE 400mm F4.5 GM OSS review highlights its portability and versatility, while its FE 600mm F6.3 GM OSS review examines the longer lens’s reach and handling.
Verdict
Sony’s FE 400mm F4.5 GM OSS and FE 600mm F6.3 GM OSS are not intended to replace the company’s flagship F2.8 and F4 super-telephoto primes. Instead, they offer a more accessible way to get serious telephoto reach in a compact and lightweight package.
The 400mm F4.5 GM OSS is the more affordable and versatile option for photographers who shoot wildlife, sports, and larger subjects. The 600mm F6.3 GM OSS provides greater native reach and is especially appealing for bird photography and distant wildlife.
Both lenses offer advanced autofocus, optical stabilization, teleconverter compatibility, and outdoor-oriented construction. Their slower apertures remain the main compromise, particularly for photographers who regularly shoot in difficult lighting.
For enthusiasts and working photographers who need long focal lengths but cannot justify a five-figure lens, this Sony super telephoto lens pair represents a compelling option. The right choice comes down to whether you value the 400mm’s flexibility or the 600mm’s extra reach.
