We talk about Sony’s “One Mount” strategy in this article. A mount for both mirrorless camera systems and Sony mirrorless video recording. Sony has announced “One Mount” many times in new product launches and they have made that clear in the actual product roadmap. Ever since Sony produced the first Crop-Frame E-mount cameras between 2010 and 2013, the first full-frame E-mount camera with their new mount was the E-mount. all without a mirror, interchangeable lenses, from Full-Frame sensor line to Crop-frame sensor line and their mirrorless video cameras share “One Mount”. By the end of 2019, Sony had a massive system of 54 E-mount lenses developed in tandem with breakthrough technologies that were also developed by themselves on mirrorless cameras. How do we review this specific Sony “One Mount” strategy process? What does it mean for consumers? How does the correlation of “One Mount” develop in correspondence with the latest technology on their cameras?
1- Sony mount lens & E mount story: 10-year journey
The mount of the lens is understood to be similar to the connection port between the lens and the camera. Each camera company has its own mount, such as Canon with EF, EF-S and mirrorless mounts with M, RF mounts; Nikon has an F mount, mirrorless mount with 1 and Z mount …, so its own lens can’t attach to other brands’ cameras.
History of Sony’s Alpha interchangeable-lens digital cameras is produced in two groups, each with different lens mounts and lens types:
- Mount A: The mount uses lenses for the Alpha DSLR camera system. The orange-red mark with a red-orange circle is marked on the camera using the A-mount.
- E-mount: The mount used for E-mount cameras is completely mirrorless, and some mirrorless professional video cameras, have interchangeable lenses. Featuring significant compactness and easy carrying with an E-mount camera kit. Machine model use of an E mount with a white dot, lens code with the letter E, for example SEL16F28.
- 2010 Sony released the first E-mount Crop-Frame camera
- 2013 Sony released the first E-mount Full-Frame camera
- 2019 Sony has 54 lenses (34 Full-Frame lenses and 20 Crop-Frame lenses)
Starting in 2010, one of the pioneers for the production of mirrorless cameras, Sony started with the Crop-Frame series as Nex3, Nex5, Nex7 … and three years later and developed the Full-Frame series. with Alpha 7, Alpha 7R, Alpha 7s … set the start of a series of technological breakthroughs in Sony mirrorless camera industry. And, they have confirmed the quality in the actual use of users, the components of Sony brand technology: image quality, processing speed, battery life, compact, enhance the system. lens.
Along with the camera is the development of lens technology, as of 2019 Sony has a collection of 54 E mount lenses (34 for FF & 20 for Crop). A great effort of Sony contributed in the research and development of the technology of video recording industry in general and for themselves in particular. Sony’s lens system prioritizes high resolution, beautiful bokeh, quiet autofocus, developed for movie shooting, compact. The system of 54 E-mount lenses with a variety of focal lengths for users to choose from focal lengths 12mm to 1200mm.
2 – Sony’s “One Mount” strategy (one mount for all)
“One Mount” – an E mount for Full-Frame, Crop-Frame and mirrorless video cameras, not only develops the same physical mount for all, but also features technology developed by Sony itself, cameras and lenses, are the optimal algorithm that combines when they are used together. Regarding lenses, they develop from lens design, lens system design, focusing motor system, lens body construction will correspond to the development of image sensor technology, image processor, electronic viewfinder. , machine body. Every time they launch a new camera, every time users wait for a technological breakthrough.
Lens system of 54 E-mount lenses, of which 34 are for Full-Frame sensor series and 20 are for Crop-Frame (APS-C) sensor series. All have general compatibility with the two camera systems. All software algorithms and data obtained from the parameters from the lens with the technology feature on the camera body achieve maximum efficiency. For example, the high resolution of a lens system (60MP) corresponds to a high resolution of a sensor; motor has a fast focusing speed corresponding to the super-fast hybrid AF speed of the body, the ability to both shoot and shoot, consuming minimal battery capacity when the autofocus mechanisms … especially The best performing features that Sony does very well is Real-time AF tracking / Real-time EYE AF.
With the simultaneous development of E-mount lens technology with a host of new camera technologies, Sony has targeted more diverse and professional users. The system has a range of focal lengths ranging from 12mm to 1200mm for all types of photography: landscape, street, sports, events, animals, portraits or studio services, architecture or products … and with the camera line also depends on the priority criteria for the genre, such as the need for high resolution for advertising images or fast speed and continuous shooting for sports, for example. It can be said that an important point is that thanks to this “One Mount”, users achieve compatibility of Full-Frame and APS-C lenses.
For example, the FF FE 24mm f / 1.4 GM lens works well on the APS-C Alpha 6500 body for example (of course there will be an equivalent angle of view in the crop ratio); or like the E PZ 18-110 F4 G OSS (APS-C) tube mounted on the FF A7 RIII / IV sensor, for example. Very flexible and do not have to think about what to do what tube, devoted whole mind to thinking and composing images only.
3 – What does “One Mount” mean in Sony’s own development of camera technology?
Sony develops a full-frame camera with high performance and a more compact and quality APS-C series. Both are E mount, use the same lens system. Sony clearly categorizes optional camera segments according to the user’s specific needs and selection criteria. For example, the current A7III series is the popular FF series, the A7RIII series has high resolution for studios or large print advertising, the A7sII serves the needs of low light or night, A9 is known as the king of speed. Crop-Frame series also inherits nearly all the new technologies of focusing speed, processing and Real-time Tracking AF & Real-time EYE AF like that.
In line with the development of sensor technology, processors and assistive AF technologies, the lens system has also developed accordingly. High-resolution lens to make the most of sensor resolution, the focusing system operates quickly and smoothly in proportion to the fast focusing speed of the camera. With such high speed, high resolution and instant processing, the battery consumes a lot of capacity and is fast, so Sony developed an intelligent and efficient energy management algorithm. For example, the A7III series has a larger battery capacity and more efficient consumption management, 710 shots on a single charge. In addition, Alpha systems can be used to charge directly from backup batteries or genuine charger accessories.
About the lens ecosystem developed by 3rd parties for their cameras is also very important for users. We have Sony and Zeiss own manufactured tubes, high-end G and G-Master series lenses. We have quite a lot of 3rd party tubes like Tamron, Sigma, Voigtlander … In addition to 54 genuine lenses, users can choose other brands’ tubes to make E. mount. One Mount “is enriched and powerful every time. Meet almost all needs from high school, semi-professional, fun to the most professional.
