Sony 100-400mm F4.5 GM OSS Review | the Best 100-400 Ever!​

Dustin Abbott








AI SUMMARY: The Sony 100-400mm F4.5 GM OSS lens presents a revolutionary design, positioned between traditional zoom lenses and high-end prime lenses, offering versatility and quality for photographers. Despite its slower maximum aperture compared to primes, it enables fast shutter speeds without significantly increasing ISO, making it practical for various shooting conditions. The lens is lightweight and user-friendly, with effective stabilization and a robust autofocus system that excels in both still and video applications. Ultimately, while the price tag of around $4300 may be steep, its performance and compatibility with teleconverters make it a worthwhile investment for serious photographers.

Strengths:

• Exceptional image quality and sharpness across focal lengths.
• Fast and reliable autofocus, particularly for action shots.
• Versatile compatibility with teleconverters, enhancing reach without significant quality loss.
• Reasonably lightweight and manageable, improving handling in the field.

Weaknesses:

• More expensive than any previous lenses in this segment
• Large size makes storage and transport more difficult
• Drop-in filter holder design could be improved

Pros:​

• Image Quality: Delivers excellent sharpness and contrast across all focal lengths, particularly at 400mm.
• Versatility with Teleconverters: Performs well with both 1.4x and 2x teleconverters, maintaining good optical quality and reach.
• Fast Autofocus: Features four XD linear motors, ensuring quick and accurate autofocus, especially in action and wildlife photography.
• Lightweight Design: Lighter than similar focal length lenses, making it easier to handle for extended periods.
• Stabilization: Equipped with effective Optical Steady Shot (OSS), which aids in reducing camera shake, especially at long focal lengths.
• Robust Build Quality: Premium construction with weather sealing and durable materials ensures longevity and reliability in diverse conditions.
• Good Minimum Focus Distance: Allows for close-up photography with a minimum focus distance of 1.5 meters.
• Smooth Bokeh: Produces aesthetically pleasing out-of-focus areas, enhancing subject isolation.
• Ergonomic Controls: Includes a comprehensive set of customizable buttons and a user-friendly zoom and focus ring design.
• Versatile Application: Suitable for both photography and videography, delivering solid focus performance in both areas.

Cons:​

• High Price: At approximately $4300, it may be considered expensive for many photographers, particularly amateurs.
• Internal Zoom Design: While beneficial for balance in the field, it may not be as compact for storage and transport as external zoom designs.
• Zoom Creep: The lens may experience zoom creep on the smooth setting, requiring careful handling when pointing downward.
• Limited Arca-Compatible Options: The tripod collar is not Arca-compatible, necessitating additional adapters for certain tripod setups.
• Function Ring Complexity: The multiple functions assignable to the ring could confuse some users, especially those unfamiliar with advanced settings.
• Fiddly Filter Mechanism: The drop-in filter holder’s design might not be as user-friendly or versatile as competing brands.

Teleconverter compatibility extends reach to 800mm​

The lens is compatible with both the Sony SEL14TC 1.4x and SEL20TC 2.0x teleconverters. With the 1.4x attached, the effective focal range becomes 140-560mm, and with the 2.0x it becomes 200-800mm. Sony specifically claims that “full G Master quality is maintained when the teleconverters are in use,” which is a notable assertion given that teleconverters typically introduce measurable optical degradation. This is one of the claims that will need verification once the lens reaches reviewers.

With the 2x converter attached, the new lens effectively covers the focal range that previously required the FE 200-600mm F5.6-6.3 G or the FE 400-800mm F6.3-8 G, which is part of why Sony has placed it in a tier above those zooms in the lineup chart.
