We discuss Sony’s E-mount lens system individually. The fact that Sony has been in the camera market for 15 years with the A-series DSLRs, Mirrorless, has also passed the 10th year since the launch of the first E-mount Crop-Frame camera (2010) Sony Alpha Nex 3 / C / F / N … and debuted the first Full-Frame E-mount camera (2013). The reality of camera companies is that when creating a new camera system or new mount, the plan to create a rich lens system for consumers is always a problem. Sony solved that problem very quickly. By the end of 2019, there were 54 lenses dedicated to the E mount of mirrorless cameras, including Full-Frame and Crop-Frame. Sony created Sony’s self-developed lens brand, Sony Zeiss cooperation, Sony G and Sony G-Master premium. They had an E-mount lens system with a range of focal lengths from super-wide (12mm) to super-telephoto (1200mm), many segments from the most popular to the most professional in both quality and design. user options.
We have compiled a system of 54 E-mount lenses for Sony camera users to easily visualize. What technology did Sony have when developing its own lens? What are the advantages that Sony has often announced and is proud of its lens resolution and specific focusing mechanism?

2. Sony E-mount lens system
Sony’s E-mount lens system up to now includes 54 tubes, with a focal length range of 12mm to 1200mm, of which 34 are for Full-Frame cameras and 20 are for Crop-Frame series. In Sony’s strategy of “One-Mount”, Sony made it clear its direction was to develop lenses for models that share an E mount, including mirrorless video camera systems. Here are some of the main symbols that you often encounter on Sony lenses.
Sony E-mount lens system we will see them very clearly distinguished: Sony, Sony Zeiss, Sony G, Sony G-Master. Not to mention third-party manufacturers that make quite a lot of E-mounts such as Sigma, Tamron, Voigt, Youngnu …, only referring to the lens system developed and cooperated with Zeiss by Sony themselves. This lens series has an “E” in the lens name, indicating that this is an E-mount lens for APS-C cameras, in order to distinguish it from lenses for Full Frame E-mounts (Full Frame E-mount) ).
About Sony and Zeiss cooperation: The two companies work closely together. One specializes in camera production, the other is famous for lenses. In the early days, thanks to the help of Zeiss, Sony quickly added a few important focal points to the E-mount lens system E. XA lens grinding technology is talked about a lot. Sony and Zeiss co-developed based on Zeiss’s existing formulas such as Planar, Sonnar, …), Zeiss-controlled production processes, and Zeiss’s renowned T * coating for images. go into better quality lenses.
E mount lenses for Crop models: On the lens the “E“in the lens name, indicates that this is an E-mount lens for the APS-C (Crop) machine, to distinguish it from a Full Frame camera with the symbol FE (Full Frame E-mount). Up to now, this lens system has covered enough focal length for the needs of most common users. Most are zoom lenses, few Prime lenses and large aperture lenses. In this system an 18-110mm lens costs up to $ 3500. This is the most expensive E-mount lens available today, designed for professional videographers who use the FS5-FS7 and have gears to use the Follow Focus system.
E-mount lenses for Full-Frame Series: The FE symbol, currently includes 34 diverse focal length lenses, most of which are high-end, expensive, serving the rigorous demands for image quality. Included is a standard Sony Lens that is self-developed and developed for Sony E-mount cameras with Full Frame sensors. The advantage of this lens line is that the good optical quality comes with a low price, suitable for everyone.
The ZA lenses manufactured by Sony and Zeiss are the FE lenses manufactured by Sony and Zeiss that also inherit Zeiss’s quintessentials such as Sonnar / Planar / Tessar optical formula, then coating with T * coating. The stabilization system of these lenses is an OSS developed by Sony.
If you require a higher quality optical lens, Sony will direct you to the Sony G series. Here is “GOLD”, which means “gold” quality. In addition to shooting still images, Sony G lenses are optimized for movie shooting. These lenses are usually F4 or larger zoom lenses, which come with OSS optical image stabilization. The number of aperture blades of the G series is increased from 6 or 7 to 9 leaves, for better bokeh, smoother gradation. Some Powerzoom lenses have an FN button on the lens that allows you to assign a focal length to it. When pressed, zoom is faster, which is especially useful when recording movies.
3. G-Master premium lens
In particular, the lens group G-Master is Sony’s line of bokeh-oriented lenses with an aperture of up to 11 leaves and other special technologies. It can be seen that Sony’s GM lenses are expensive, even higher than Sony Zeiss lenses. Sony is gradually bringing special technologies from the Minolta era back to the E-mount lens, such as the Smooth Trans Focus (STF) technology on the Sony FE 100mm F2.8 STF GM OSS. High quality price, which can be explained by the fact that the GM zoom lens has a larger aperture than the ZA series and the focal length is also longer, the structure is more complicated, more lenses are available, Sony says this is a series of advantages. point:
- High resolution (more than 60MPX), effectively compatible with the resolution of the camera sensor.
- Circular bokeh system, smooth contrast, full-frame sharpness
- Integrated motor system super fast and accurate focus, do not use the old drive rotation system).
- The sync works well with Real-time Tracking AF and Real-time EYE AF, fast focusing.
With the integration of advanced technologies in lenses, lens systems, focusing systems … Sony wants to emphasize the “high resolution” that their lens systems bring. The light passes through the high-end lens system and the processing coatings to achieve the highest and highest brightness quality when in contact with the image sensor surface, helping to reproduce images with quality sharpness. tallest. Real-time tracking AF works extremely fast continuously making shooting easier and more reassuring; In particular, real-time EYE Focus is very sensitive when it has focus and the subject moves away from the eyes, it still follows the face recognition pattern and returns to focus the eye when the subject comes back. Applies to both humans and animals, and not just with photography, but with similar activities when shooting videos.
And, the problem that Sony wants is the lens system must also develop in sync with the breakthrough technology development on the body too many technologies they are always developing breakthroughs. That is a remarkable point of Sony. We can see they invest a lot in optimizing the resolution of the lens. High image details in addition to sensor resolution, fast and accurate focusing system, the resolution of the lens is decisive right from the input of light (amount of light & quality of light).
The camera has a lot of technologies both physical hardware, algorithm software, more developed & useful in the reality of the user, making shooting easier, simpler, and less worrying. , or minimize the worry about sharpness, not bright enough … The photographer spends more time thinking about the composition, choosing the shooting angle, focusing on a decisive moment to photograph Photo more successful. Lens and technologies are always improving, diverse focal lengths, optimizing the quality of light and the amount of light passing through … is an important part of the recording. Thanks Sony!
