Sony FE 100-400mm f/4.5-5.6 GM OSS: A Versatile Telephoto Zoom
The Sony FE 100-400mm f/4.5-5.6 GM OSS is a professional-grade telephoto zoom lens designed for Sony's full-frame E-mount mirrorless cameras. Announced alongside the Sony Alpha 9 body, this lens fills a crucial gap in Sony's lineup, providing photographers with a versatile focal range suitable for various scenarios, especially wildlife photography¹.
Key Features:
Focal Length Range: 100-400mm
- The 100-400mm focal length range is incredibly useful for wildlife photography. At the wide end (100mm), it's great for close-up shots of animals and environmental portraits. As you zoom in, it becomes ideal for capturing distant mammals and large birds.
G Master Optics: High Resolution and Bokeh
- As part of Sony's G Master (GM) lens lineup, the FE 100-400mm aims for exceptional image quality. It delivers high resolution across the entire zoom range.
- The lens also produces beautiful bokeh (that creamy, out-of-focus background) thanks to its optical design.
Build Quality and Handling
- The lens feels robust in hand, with a magnesium-alloy barrel construction. It's weather-sealed throughout, making it suitable for outdoor shooting.
- A rubber gasket around the bayonet mount helps protect both the lens's rear element and the camera sensor from moisture.
- However, some users have reported mixed experiences with weather sealing, especially in high humidity conditions.
Compact and Lightweight
- Considering its focal length range, the lens is relatively compact. It measures 94x205mm and weighs 1395g.
- This compact form factor pairs well with Sony's A7 and A9 mirrorless bodies.
Optical Image Stabilization (OSS)
- The lens features effective optical image stabilization, reducing camera shake by up to 5 stops. This is crucial for handheld shooting at longer focal lengths.
Lens Elements and Coatings
- The lens construction includes 22 elements in 16 groups.
- It uses Super ED (Extra-low Dispersion) and ED (Extra-low Dispersion) glass elements to minimize chromatic aberration.
- The front element has a fluorine coating to repel dirt and fingerprints.
Minimum Focus Distance and Magnification
- The lens can focus as close as 98cm (3.2 feet), allowing for some impressive close-ups.
- Maximum magnification is 0.35x, which is quite good for a telephoto lens.
Dust and Moisture Resistance
- In addition to weather sealing, the lens is designed to withstand dust and moisture, making it suitable for challenging environments.
In summary, the Sony FE 100-400mm f/4.5-5.6 GM OSS is a powerful tool for wildlife enthusiasts, sports photographers, and anyone needing that extra reach. Its combination of performance, build quality, and compactness makes it a standout lens in the Sony E-mount lineup.
