(1)

The Sony 24mm f/1.4 GM was released in September 2018 as a revolutionary wide-angle prime.

The Sony 24mm f/1.4 GM quickly became the gold standard for astrophotographers and landscape shooters. (2)

What makes the Sony 24mm f/1.4 GM so special? First, the combination of 24mm wide angle and f/1.4 aperture is unique – very few lenses offer this. Second, the 2 XA elements deliver exceptional sharpness from edge to edge, even wide open. Third, the 11-blade circular aperture produces incredibly smooth, round bokeh. The Sony 24mm f/1.4 GM is a masterpiece. (3)

Key Specifications of the Sony 24mm f/1.4 GM

The specifications above only hint at what the Sony 24mm f/1.4 GM can do. In practice, this lens delivers extraordinary results. (6)

The Ultimate Astrophotography Lens

The Sony 24mm f/1.4 GM is widely considered one of the best lenses for astrophotography. The combination of 24mm wide angle and f/1.4 aperture is exceptional for night sky photography. (7)

What does 24mm and f/1.4 mean for astrophotography with the Sony 24mm f/1.4 GM? At f/1.4, the lens gathers significantly more light than f/2.8 lenses. For night sky photography, light gathering is everything. The Sony 24mm f/1.4 GM lets you use lower ISO settings, resulting in cleaner, less noisy images of the Milky Way. (8)

The 24mm focal length is wide enough to capture sweeping vistas of the night sky but not so wide that the Milky Way becomes too small. Many astrophotographers consider 24mm the perfect balance between width and detail. (9)

Crucially, the Sony 24mm f/1.4 GM has excellent coma control. Coma is an aberration that turns stars into “birds” or “butterflies” in the corners of the frame. Many wide-angle lenses suffer from coma. The Sony 24mm f/1.4 GM does not. Stars remain sharp points from edge to edge, even at f/1.4. (10)

For astrophotographers, this is the lens. Japanese users praise the Sony 24mm f/1.4 GM: “星空撮影に最適なレンズ。F1.4の明るさと周辺までの高い解像力が素晴らしい” (The ideal lens for night sky photography. The brightness of f/1.4 and high resolution to the edges are outstanding.) (11)

The minimum focus distance of 0.24m (9.5 inches) allows for foreground interest in astrophotography compositions. You can include rocks, trees, or structures in the foreground while keeping the stars sharp. (12)

Ultra-Wide 84° Angle of View

The Sony 24mm f/1.4 GM provides an 84° angle of view on full-frame cameras. This is wide enough for dramatic compositions but not so wide that distortion becomes problematic. (13)

What can you do with 84°? You can photograph landscapes with sweeping foregrounds. You can capture environmental portraits that show the subject in context. You can photograph architecture and interiors. The Sony 24mm f/1.4 GM is incredibly versatile. (14)

For landscape photographers, the 24mm focal length is a classic. It is wide enough to capture dramatic vistas but not so wide that foreground elements become tiny. Many landscape photographers consider 24mm their go-to wide angle. (15)

For environmental portraits, the Sony 24mm f/1.4 GM captures the subject in their context. A chef in the kitchen, a musician in the studio, a craftsman in the workshop – the 24mm lens tells the story. (16)

On APS-C cameras (A6700, ZV-E10, FX30), the Sony 24mm f/1.4 GM provides a 36mm equivalent field of view. This is a classic standard focal length, perfect for street photography and everyday shooting. (17)

Japanese users note: “24mmは風景からポートレートまで幅広く使える focal length” (24mm is a versatile focal length that can be used for everything from landscapes to portraits.) (18)

Ultra-Fast f/1.4 Aperture

The Sony 24mm f/1.4 GM features an ultra-fast f/1.4 maximum aperture. This is exceptionally bright for a wide-angle lens. Most 24mm lenses are f/2.8 or slower. The Sony 24mm f/1.4 GM lets in four times as much light as an f/2.8 lens. (19)

What does f/1.4 mean for your photography? For astrophotography, it means cleaner images at lower ISO. For indoor photography, it means shooting in available light without flash. For environmental portraits, it means creating separation between subject and background. (20)

At 24mm, even at f/1.4, the depth of field is not extremely shallow. The hyperfocal distance at 24mm and f/1.4 is approximately 10 meters. Focus at 10 meters, and everything from 5 meters to infinity is sharp. This makes the Sony 24mm f/1.4 GM very usable for street and landscape work even wide open. (21)

The 11-blade circular aperture produces exceptionally smooth, round bokeh when shooting close subjects. The bokeh from the Sony 24mm f/1.4 GM is beautiful – creamy and natural. (22)

Japanese users praise the aperture: “F1.4の明るさは圧倒的。暗所での撮影が格段に楽になる” (The brightness of f/1.4 is overwhelming. It makes shooting in low light significantly easier.) (23)

2 XA Elements – Edge-to-Edge Sharpness

The Sony 24mm f/1.4 GM features 2 XA (extreme aspherical) elements and 3 ED glass elements. This advanced optical design delivers exceptional sharpness from edge to edge, even wide open at f/1.4. (24)

What does this mean for your images? The corners of your photos will be as sharp as the center. For astrophotography, stars in the corners remain sharp points. For landscape, foreground details remain crisp. The Sony 24mm f/1.4 GM is optically superb. (25)

Center sharpness on the Sony 24mm f/1.4 GM is outstanding from f/1.4. At f/1.4, the center is tack sharp. At f/2 and f/2.8, sharpness is even higher. For most shooting, you can confidently use the Sony 24mm f/1.4 GM wide open. (26)

Corner sharpness is also excellent. At f/1.4, corners are very good – better than any other 24mm lens. Stopped down to f/2.8, corners become exceptional. The Sony 24mm f/1.4 GM is sharp across the entire frame. (27)

Distortion is minimal for a 24mm lens. There is slight barrel distortion, easily corrected in-camera or in post-processing. (28)

Chromatic aberration is virtually non-existent. The ED glass elements effectively eliminate purple fringing. Even in high-contrast scenes, the Sony 24mm f/1.4 GM produces clean, color-accurate images. (29)

Japanese users summarize: “開放F1.4から画面全域で妥協のない高解像性能” (Uncompromising high-resolution performance across the entire frame from f/1.4.) (30)

Remarkably Lightweight at 445g

The Sony 24mm f/1.4 GM weighs only 445g. For an f/1.4 wide-angle lens with autofocus, this is remarkably light. To put this in perspective, many 24mm f/1.4 lenses for DSLRs weigh 700-900g. The Sony 24mm f/1.4 GM is approximately 35-50% lighter than competitors. (31)

At 445g, the Sony 24mm f/1.4 GM is a joy to carry. You can keep it in your camera bag without noticing the weight. For travel photographers, this matters. For astrophotographers hiking to remote locations, this matters. (32)

The compact size also makes the Sony 24mm f/1.4 GM gimbal-friendly. Balancing a gimbal is easier with a 445g lens than with a heavier alternative. (33)

Japanese users appreciate the weight: “軽量でコンパクト、持ち運びに便利” (Lightweight, compact, convenient to carry.) (34)

11-Blade Circular Aperture – Beautiful Bokeh

The Sony 24mm f/1.4 GM features an 11-blade circular aperture – the maximum number of blades available. More blades mean rounder bokeh, especially when stopped down. (35)

What does 11 blades do for the Sony 24mm f/1.4 GM? At f/1.4, the aperture is wide open. But when you stop down to f/2, f/2.8, or f/4, the 11-blade aperture remains nearly circular. The result is that bokeh balls stay round, not polygonal. (36)

The bokeh from the Sony 24mm f/1.4 GM is exceptionally smooth and creamy. For a wide-angle lens, this is unusual. Most wide-angle lenses have harsh, distracting bokeh. The Sony 24mm f/1.4 GM does not. (37)

For environmental portraits where you want to blur the background while keeping the subject sharp, the Sony 24mm f/1.4 GM delivers. (38)

Focus Hold Button and Aperture Ring

The Sony 24mm f/1.4 GM features a customizable focus hold button. You can assign different functions through your camera menu. Common assignments include eye AF and focus magnifier. (39)

The lens also features a linear response MF ring. When you turn the focus ring, the lens responds directly and linearly – no acceleration lag. This is essential for precise manual focus for astrophotography. (40)

The Sony 24mm f/1.4 GM also features an aperture ring with a click ON/OFF switch. In clicked mode, the aperture ring has tactile stops. In de-clicked mode, the ring rotates smoothly – essential for video work. (41)

Weather-Sealed Construction

The Sony 24mm f/1.4 GM features dust and moisture-resistant construction. The lens mount has a rubber gasket. The barrel is sealed at key points. The buttons and switches are sealed. (42)

For outdoor photographers, this weather sealing provides peace of mind. You can use the Sony 24mm f/1.4 GM in light rain, at the beach, or in dusty environments without worry. (43)

The front element features a fluorine coating that repels water, oil, and smudges. This makes the 24mm f/1.4 GM easy to clean – a welcome feature for outdoor shooting. (44)

Japanese users confirm: “防塵・防滴でアウトドアでも安心して使える” (Dust and moisture resistant, so you can use it outdoors with confidence.) (45)
