"Our goal with the 28-70mm F2 G Master was to create a high-performing zoom lens that could be a strong single lens alternative to multiple primes," said Yang Cheng, Vice President of Imaging Solutions, Sony Electronics Inc. "We prioritized a lightweight design during the engineering process as we knew that was a critical factor for real-life, practical use. And in a manner that only Sony can do, we were able to deliver a small, standard F2 zoom lens that does not sacrifice image quality. We're proud to add this to our G Master series and believe it is one of the most innovative lenses ever offered to professionals."

索尼電子公司成像解決方案副總裁楊成說:「我們對28-70mm F2 G Master的目標是打造一款高性能的變焦鏡頭,它可以作爲多鏡頭的強大替代品,」 索尼電子公司成像解決方案副總裁楊成說,「我們在工程過程中優先考慮輕質設計,因爲我們知道這是現實生活中實際使用的關鍵因素。以只有索尼才能做到的方式,我們能夠提供一款不犧牲圖像質量的小型、標準 F2 變焦鏡頭。我們很自豪能將其添加到我們的 G Master 系列中,並相信它是有史以來爲專業人士提供的最具創新性的鏡頭之一。」

Sharp Imagery and Beautiful Bokeh

清晰的圖像和美麗的散景

The 28-70mm F2 G Master produces extremely sharp corner-to-corner results throughout the entire zoom range, even while shooting wide open at F2. The high-resolution output is made possible by the three XA (extreme aspherical) elements and three aspherical elements built within the lens that minimize aberrations. The lens also features a floating focusing system that helps maintain internal stability. This focusing mechanism enables an impressive minimum focusing distance of up to 14.8 inches (0.38m) throughout the entire zoom range.

28-70mm F2 G Master 在整個變焦範圍內都能產生極其清晰的角到角效果,即使在 F2 下也是如此。高分辨率輸出是由三個 XA(極限非球面)鏡片和三個內置在鏡頭內的非球面元件實現的,它們最大限度地減少了像差。該鏡頭還具有浮動聚焦系統,有助於保持內部穩定性。這種對焦機制可在整個變焦範圍內實現令人印象深刻的最小對焦距離,最高可達 14.8 英寸(0.38 米)。

Staying true to the G Master lens lineage, the lens' aperture up to F2 produces extraordinary bokeh, ideal for creating images that showcase a shallow depth of field. The 28-70mm F2 amplifies the G Master bokeh standards through a newly designed 11-blade circular aperture unit. Chromatic aberrations, which cause color fringing within photos, are effectively minimized with three Super ED (extra-low dispersion) elements and one ED element built within the lens. Additionally, Sony's Nano AR Coating II reduces flare and internal reflections, ensuring clear images, even when strong light sources are present in the frame.

忠實於 G Master 鏡頭系列,鏡頭光圈高達 F2,可產生非凡的散景,非常適合創建呈現淺景深的圖像。28-70mm F2 通過全新設計的 11 葉片圓形光圈單元放大了 G Master 散景標準。鏡頭內內置三個 Super ED(超低色散)元件和一個 ED 元件,可有效最大限度地減少導致照片中出現色彩邊緣的色差。此外,索尼的Nano AR Coating II可減少耀斑和內部反射,即使畫面中有強光源,也能確保清晰的圖像。

Compact, Lightweight Design Without Compromising Quality

緊湊、輕巧的設計,不影響質量

The 28-70mm F2 G Master is one of the most advanced mirrorless camera lenses manufactured with a total 20 different lens elements arranged within 14 internal groups. Despite the advanced optical design, the lens remains compact at 3.6 x 5.5 inches (92.9 x 139.8mm) and lightweight at approximately 32.3 ounces (918g). The combination of imaging performance and a compact form factor offers an innovative solution that meets the demands of industry professionals.

28-70mm F2 G Master 是最先進的無反光鏡相機鏡頭之一,共有 20 個不同的鏡頭元件排列在 14 個內部組中。儘管採用了先進的光學設計,但鏡頭仍然緊湊,僅爲3.6 x 5.5英寸(92.9 x 139.8毫米),重量約爲32.3盎司(918克)。成像性能和緊湊的外形相結合,提供了滿足行業專業人士需求的創新解決方案。

Precise Autofocus Tracking with Instant Response

精確的自動對焦跟蹤,即時響應

Reliable and responsive autofocus is delivered through the lens' four XD (extreme dynamic) linear motors powered by advanced control algorithms. This smooth performance system provides accurate and quick focus tracking, often essential in many professional use cases like weddings and sports. This lens is fully compatible with Sony's Alpha 9 III's high-speed continuous shooting capabilities of up to 120 frames per secondiii with AF/AE (autofocus/autoexposure) tracking, even while zooming.

鏡頭的四個 XD(極限動態)線性電機由高級控制算法提供動力,實現了可靠且響應迅速的自動對焦。這種流暢的性能系統可提供準確、快速的對焦跟蹤,這在婚禮和體育運動等許多專業用例中通常是必不可少的。這款鏡頭完全兼容索尼Alpha 9 III的高速連拍功能,最高可達每秒 120 幀,即使在變焦時也能進行自動對焦/自動曝光(自動對焦/自動曝光)跟蹤。

Designed for High-Performance Video Shooting

專爲高性能視頻拍攝而設計

Along with its F2 aperture, the zoom range of the 28-70mm G Master provides a versatile video option that can cover standard field-of-view shots and tighter compositions up to 70mm. This lens minimizes focus breathing through its build and compatibility with the Breathing Compensation feature on various Alpha bodiesiv. Its high autofocus performance ensures reliable focus even when recording in high frame rates up to 4K 120p / FHD 240pv. Additionally, the XD linear motors and newly developed aperture unit operates silently, preventing any lens noise from being captured during filming.

除了 F2 光圈外,還有28-7000萬的變焦範圍。G Master 提供多功能視頻選項,可以涵蓋標準視野鏡頭和最大 70 毫米的更緊密構圖。該鏡頭通過其構造以及與各種 Alpha bodiesiv 的呼吸補償功能的兼容性最大限度地減少了呼吸對焦。即使在高達 0.4萬 120p/FHD 240pv 的高幀率下錄製時,其高自動對焦性能也能確保可靠的對焦。此外,XD 線性馬達和新開發的光圈單元可以靜音運行,防止在拍攝過程中捕獲任何鏡頭噪點。

The lens is ideal for gimbal use with a minimal zoom extension of approximately .68 inches. The compact form factor and short external zoom helps maintain gimbal balance, even at varying focal lengths.

該鏡頭非常適合雲臺使用,最小變焦距離約爲 0.68 英寸。緊湊的外形和較短的外部變焦有助於保持雲臺平衡,即使在不同的焦距下也是如此。

Operability and Reliability for Versatile Control

多功能控制的可操作性和可靠性

Key control features include Linear Response MF for intuitive manual focusing, adjustable zoom ring torque, and an aperture ring with a click ON/OFF switch. The lens also offers two customizable focus hold buttons, an iris lock switch, and an AF/MF switch. The 28-70mm F2 G Master has an 86mm filter diameter and a convenient window on the lens hood for variable filter adjustments.

主要控制功能包括用於直觀手動對焦的線性響應 MF、可調節的變焦環扭矩以及帶有點擊開/關開關的光圈環。該鏡頭還提供兩個可自定義的對焦保持按鈕、一個光圈鎖定開關和一個 AF/MF 開關。28-70mm F2 G Master 的濾鏡直徑爲 86 毫米,鏡頭遮光罩上有一個便於調整濾鏡的窗口。

For durability, all buttons and switches are sealed with silicone gaskets, and critical areas are designed to resist dust and moisturevi. This ensures reliability, even while using in challenging outdoor environments. Additionally, a fluorine coating on the front element repels contaminants for easy cleaning.

爲了經久耐用,所有按鈕和開關均使用硅膠墊圈密封,關鍵區域設計用於防塵和防潮。即使在惡劣的戶外環境中使用,這也能確保可靠性。此外,前部元件上的氟塗層可排斥污染物,便於清潔。
