The Sony 18-105mm f/4 G OSS is the lens that many videographers and content creators rely on. (1)

The Sony 18-105mm f/4 G OSS was released in 2013 as a G Lens – Sony’s professional-grade series below G Master.

Key Specifications of the Sony 18-105mm f/4 G OSS

The specifications above show why the Sony 18-105mm f/4 G OSS is such a popular lens for video and travel. The constant f/4 aperture and power zoom are the key features. (6)

The Perfect All-in-One Zoom Range for APS-C

The Sony 18-105mm f/4 G OSS covers 18-105mm, which translates to 27-157.5mm full-frame equivalent on Sony APS-C cameras. This is the most useful zoom range for everyday photography and video. (7)

What does 18-105mm give you on APS-C?

At 18mm (27mm equivalent), the Sony 18-105mm f/4 G OSS captures wide landscapes, architecture, and vlogging selfies. The 18mm wide end is wide enough for selfie framing at arm’s length. (9)

At 35-50mm (52-75mm equivalent), the Sony 18-105mm f/4 G OSS provides a natural perspective that matches human vision. This is where you will shoot most of your documentary and street photography. (10)

At 70-105mm (105-157mm equivalent), the Sony 18-105mm f/4 G OSS delivers flattering portraits with pleasing background compression. The 105mm telephoto end brings distant subjects closer. (11)

For travel photographers, the Sony 18-105mm f/4 G OSS is an excellent one-lens solution. You can shoot wide landscapes at 18mm, street scenes at 35mm, and portraits at 105mm – all without changing lenses. (12)

Japanese users praise the range: *“18-105mmは旅行に最適な焦点距離。広角から望遠まで一本でカバー”* (18-105mm is the ideal focal range for travel. One lens covers wide-angle to telephoto.) (13)

Power Zoom – Perfect for Video

The Sony 18-105mm f/4 G OSS features a power zoom mechanism. The zoom is controlled electronically, not manually. This is a key feature for videographers. (14)

What does power zoom mean for your video work? You can zoom smoothly and consistently – something that is difficult to do manually. The zoom speed is adjustable. You can zoom slowly for dramatic reveals or quickly for action. (15)

The power zoom can be controlled via the zoom rocker on the lens barrel, via camera controls, or even remotely via the Sony app. For gimbal users, the ability to zoom without touching the lens is valuable. (16)

For vloggers, the power zoom is useful. You can zoom from wide to telephoto while keeping the camera steady. The zoom is quiet – no noise is picked up by the microphone. (17)

Japanese users praise the power zoom: “動画撮影時のズームがスムーズで、電動ズームは非常に便利” (The zoom during video recording is smooth, and the power zoom is very convenient.) (18)

Constant f/4 Aperture

The Sony 18-105mm f/4 G OSS features a constant f/4 aperture throughout the zoom range. This means that whether you are shooting at 18mm or 105mm, the maximum aperture remains f/4. (19)

Why does constant aperture matter? For photographers, consistent aperture means consistent exposure. When you zoom, your shutter speed and ISO do not need to adjust. This makes the Sony 18-105mm f/4 G OSS very efficient to use. (20)

For videographers, constant aperture is essential. When you zoom during a video shot, the Sony 18-105mm f/4 G OSS maintains the same exposure. There is no sudden brightness change as you zoom. This is why this lens is popular for event videography and vlogging. (21)

The f/4 aperture is one stop faster than typical kit lenses that slow down to f/5.6 or f/6.3 at the telephoto end. The Sony 18-105mm f/4 G OSS lets in twice as much light at 105mm as a kit lens. (22)

Japanese users note: “F4通しは動画撮影で非常に便利” (Constant f/4 is very convenient for video shooting.) (23)

Optical SteadyShot (OSS) Stabilization

The Sony 18-105mm f/4 G OSS features built-in Optical SteadyShot image stabilization. This is valuable for handheld shooting, especially at the 105mm telephoto end. (24)

What does OSS do? The stabilization system compensates for camera shake, allowing you to shoot at slower shutter speeds without motion blur. At 105mm, you might handhold the Sony 18-105mm f/4 G OSS at 1/60 or 1/50 of a second and still get sharp images. (25)

For handheld video, the Sony 18-105mm f/4 G OSS provides smooth, stable footage. The OSS system smooths out micro-shakes. This makes the lens popular for run-and-gun shooters. (26)

When paired with a Sony camera body that has IBIS (like the A6700, A6600, or A6500), the stabilization is even more effective. The combination of OSS and IBIS provides 5-6 stops of shake correction. (27)

Japanese users confirm: “手ブレ補正が効くので、手持ち撮影でも安心” (Image stabilization works, so you can shoot handheld with confidence.) (28)

Optical Performance

The Sony 18-105mm f/4 G OSS delivers good optical performance for a superzoom lens. The optical design includes 2 ED elements and 3 aspherical elements to control aberrations. (29)

Center sharpness on the Sony 18-105mm f/4 G OSS is good across the zoom range. At 18mm, the center is sharp. At 50mm, the center is very sharp. At 105mm, the center remains sharp. Stopped down to f/5.6 or f/8, sharpness is better. (30)

Corner sharpness is acceptable. At 18mm and f/4, corners are softer – typical for superzoom lenses. Stopping down to f/5.6 improves corners. For video work, corner sharpness is less critical. (31)

Distortion is present but correctable. At 18mm, there is noticeable barrel distortion. In-camera correction or post-processing eliminates it. At 35-105mm, distortion is minimal. (32)

Chromatic aberration is present in high-contrast scenes but is not severe. Most editing software removes it automatically. (33)

For a superzoom lens, the Sony 18-105mm f/4 G OSS performs well. It is not a G Master, but for video and travel, it is excellent. (34)

Japanese users summarize: “動画撮影用として考えれば十分な解像力” (Sufficient resolution when considered for video shooting.) (35)

Build Quality and Handling

The Sony 18-105mm f/4 G OSS is well-built for its class. The lens barrel is constructed from metal and high-quality plastic. The zoom and focus rings are smooth. (36)

The lens features a power zoom rocker on the side of the barrel. The zoom speed is variable – press lightly for slow zoom, press harder for fast zoom. The zoom is smooth and consistent. (37)

The Sony 18-105mm f/4 G OSS has an AF/MF switch and an OSS on/off switch. The focus ring is electronic (focus-by-wire). (38)

The lens hood is included and reversible for storage. The filter thread is 72mm – a common size. (39)

The Sony 18-105mm f/4 G OSS weighs 427g. This is heavier than kit lenses but lighter than full-frame equivalents. The weight is well-balanced on A6000 series bodies. (40)
