SAN DIEGO – November 7, 2023 – Sony Electronics is pleased to announce the release of the world’s lightesti 300mm telephoto prime lens G Master™ (SEL300F28GM), a full-frame α™ (Alpha™) E-mount lens with a maximum aperture of F2.8.

The anticipated FE 300mm F2.8 G Master OSS lens has the high depiction performance and high-speed, high-precision AF (autofocus) which are the hallmark of G Master. The lightweight design of approximately 1470gii (excluding tripod mount) and excellent weight balance allow the user to capture sharp, dynamic and decisive moments such as those of fast-moving sports or agile animals with handheld shooting. Paired with the Alpha 9 III full-frame camera that also launched today, high-speed continuous shooting with AF/AE tracking up to 120 frames per second is possibleiii. Even subjects with complex and diversified movements can be tracked with high precision. It is an ideal match for lightweight camera bodies by reducing the load on the user, minimizing fatigue during long handheld shooting sessions. It is also compatible with an optional teleconverter, allowing the user to shoot in the telephoto range of up to 600mm (equivalent to 900mm when using with an APS-C camera)iv.

“Ever since our announcement of the development of this lens in January of this year, we have received an overwhelming number of positive reactions from photographers around the world who are looking forward to its release,” said Yang Cheng, Vice President, Imaging Solutions, Sony Electronics. “By adding this 300mm lens to the already available E-mount 400mm and 600mm super-telephoto prime lenses,it supports a wide range of needs and shooting environments for professional and advanced amateur photographers.”

Main Features of the FE 300mm F2.8 G Master OSS

G Master Telephoto Lens that Captures Decisive Moments with High Resolution and Beautiful Bokeh

Incorporating Sony's cutting-edge technology, the G Master's high-resolution performance and beautiful bokeh makes the subject stand out clearly and capture decisive moments such as sports, news reports, events, and wildlife photography. An innovative optical design that includes three Super ED (Extra-low Dispersion) glass elements and one ED glass element, effectively placed to suppress chromatic aberration and achieve high resolution and contrast across the entire frame. Outstanding resolution and contrast are maintained right out to the image edges, which also allows for more flexible cropping and editing.

The gorgeous, creamy bokeh is a hallmark of the G Master design and ideally complements the lens’s 300 mm focal length and F2.8 maximum aperture, allowing the use of narrow depth of field to make subjects stand out from the background. Each lens is individually calibrated during manufacture to optimize bokeh quality and has an 11-blade circular aperture mechanism that contributes to smooth rounded bokeh. ​  

High-Performance AF that Captures Dynamic Moments and High-Speed Continuous Shooting with AE/AF Tracking up to 120 Frames per Secondiii

The combination of two latest XD (extreme dynamic) Linear Motors and control algorithms provide high-speed, high-precision, and low-vibration AF performance. When combined with the newly announced Alpha 9 III full-frame camera, high-speed continuous shooting with AF/AE tracking of up to 120 frames per second is possible. This allows dynamic subjects to be captured without missing a moment’s opportunity, even when shooting scenes in which the subject moves quickly, such as sports or animals, or scenes in which the subject moves erratically, such as at competitive events. The high AF performance is demonstrated even when the separately sold teleconverteriii is attached.

Exceptional Mobility and Comfortable Operability that Support Professionals in the Field 

Extensive weight reduction measures make FE 300mm F2.8 GM OSS the lightest in its classi, at approximately 1470g (excluding tripod mount) and has been designed with consideration to weight balance. The internal lens barrel uses durable magnesium alloy to achieve both high robustness and light weight. The weight is not concentrated at the front of the lens barrel, making it highly stable and allows for agile and accurate panning while shooting. In addition, MODE3vi, which provides enhanced viewfinder stability and optimizes the image stabilization algorithm, allows you to accurately capture dynamic scenes.

When used with the Alpha 9 III, the user can assign “preset focus” to the function ring that allows for an instant recall of focus to any pre-determined positionvii. Furthermore, the lens features comfortable operability that supports professional shooting, including focus hold buttons placed in four locations that can be assigned to the favorite functions from the camera body making it ideal for any professional.

The FE 300mm F2.8 G Master OSS has a dust and moisture resistant designviii along with fluorine coating to help prevent dirt and fingerprints to keep up with the needs of professional photographers.

  1. Lightweight and small and I give Sony a lot of credit for making such a lens. The price is reasonable as well. With that said, I much prefer the flexibility of the RF 100-300 mm f2.8 even though it weight considerably more. Bravo to both Canon and Sony for making excellent products.

  2. Sony has a winner here, because of the price. It will sell like hot cakes.
    It is the same cost of the Canon EF300/2.8 but of course smaller... note that if you want more focal range than just 300mm then the RF100-300mm is more flexible at the same cost as the Sony 300mm/2.8 plus 70-200/2.8.

    It is basically a 1 camera setup vs a 2 camera setup.
    Either that or a 2-camera setup from 24-105 f/2.8 to 100-300 f/2.8 completely covering far more range.

    Sure but Canon 24-105/2.8 + 100-300/2.8 cost about $4000 more than Sony 70-200/2.8 + 300/2.8.

    BTW Sony 70-200/2.8 + 300/2.8 is still lighter (and cheaper) than Canon 100-300/2.8 :LOL:

    Not if you are carrying 2 bodies to cover that range ie not swapping lenses.

    Depending on which market you are buying, the price of the Sony 300/2.8 is USD6k and the Sony 70-200/2.8 is USD2800... so only USD200 cheaper than the RF100-300. I would suggest that ~2% cost difference is negligible in this context.

    The are designing it with different philosophy.

    Canon is making it for professional in stadium that will position in a static spot, with tripod/monopod. And the focal length before 300mm gives so much flexibility in tracking sport subjects.

    Sony is designing it for the one-man-army. Extreme weight saving for handheld with minimal accessories. However its usage is no different than traditional SLR/DSLR equivalent.

    Whether you want to switch lenses or not. It's down to how you use it. Typical folks on internet are more likely to be one man enthusiast, so bias towards Sony as it seems better for their use...IRL international sporting events, I doubt you cannot find a RF100-300L.

    What CaNiSo are all preparing for Olympics...Nikon focus on the Super-tele primes, Canon on zooms, and Sony is trimming the weight down to extreme. It's a great time to enjoy gears.

  7. Canon is making it for professional in stadium that will position in a static spot, with tripod/monopod.
    It is not so heavy that it can't be used handheld.
    However, I agree that it will mostly be used on a monopod.
    I also think it will be used handheld along with a 400 f/2.8 on a monopod.

    And just to point out you also cover 24-70 mm with the Canon two lens setup vs. the alternative proposal.

    Don't get be wrong the Sony 300 mm f2.8 lens is an amazing achievement. However, being able to take one lens (RF 100-300 mm) instead of two lens is a huge benefit in terms of space when packing. The RF 24-105 f4 or f2.8 and the RF 100-300 mm makes a very portable two lens system that when combined with TCs covers 24-600 mm with a minimal f-stop of f5.6.

    Sony 24-70/2.8 + 70-200/2.8 + 300/2.8 = $11,100 and 3.2 kg
    Canon 24-105/2.8 + 100-300/2.8 = $12,500 and 3.9 kg

    Personally, I will take the extra cost and weight to gain the flexibility of covering that range with two zoom lenses. Others would not. Choice is good.

    A 300mm never tempted me, but a 100-300 does, wildly! :love:
    PS: A Sony wouldn't tempt me anyway...

    The 300/2.8 II did tempt me, but by the time I decided I wanted to actually buy one they weren't available new anywhere, then I got an R3 and decided to hold off for the RF version. I was disappointed at first that they went zoom over prime, and I still wish the lens were smaller than it is. But I found a holster case that can hold it mounted on the R3 (Think Tank DH-150), and after seeing that I use the full zoom range I am really glad it's a zoom.
