Sony a9 Features In Detail

This mechanism-free camera can deliver a-class-above performance conventional mechanical SLRs have only sought.

For example, this system realises a totally blackout-free viewfinder while conventional systems can only try to reduce blackout time.

A high-speed, vibration-free, silent Anti-Distortion shutter vastly extends the range of shooting situations while a mechanical system can only aim for lower vibration and quieter shutter release sound.

a9 provides continuous tracking of moving subjects for foolproof AF/AE while traditional SLRs can only challenge such AF/AE performance improvements.

Moreover, a9 allows its viewfinder to show not only images of the subject available on conventional systems but also the final image of a shot.

Now, thanks to a new image sensor that superbly manages all these roles, you can surpass all expectation with a9.

Note: This camera is equipped with electronic and mechanical shutters. The features described in this section are primarily related to electronic shutter operation.

Innovative full-frame stacked CMOS sensor with integral memory

a9 liberates you from the limits of conventional SLRs that rely on mechanical systems.

First to use high-speed stacked design, its 24.2-megapixel full-frame image sensor temporarily stores large-volume data in the integral memory for overall 20 times faster readout speed.

The combination of CMOS sensor and enhanced Bionz X image-processing engine brings you true digital freedom.

High-speed continuous shooting at up to 20fps

Groundbreaking full-frame Exmor RS CMOS sensor and Bionz X processor team up for 20fps continuous shooting with AF/AE tracking. Stunning high-speed performance and ample buffer let you capture the decisive moment.

Blackout-free shooting

Non-mechanical electronic shutter eliminates blackout with typical SLR mirror action. An uninterrupted view of the subject is available even during shutter release, with 60fps live-view capability and minimal display lag in continuous shooting.

AF/AE calculations up to 60 times/sec

Light directly reaches the image sensor without mechanical interruption. An ingenious fusion of mirrorless construction and new speed-enhancing technologies provides AF/AE at the full-frame focal plane.

Electronic shutter speeds up to 1/32,000 sec

These far surpass mechanical shutters for a new imaging expression. You can also maintain shallow depth of field without an ND filter, even under bright conditions.

No noise distraction

An anti-distortion electronic shutter allows silent shooting without mechanical mirror and shutter noise.

It is ideal for sports and subjects that demand quiet operation, greatly expanding camera versatility.

No unwanted vibration

During SLR shooting, mirror shock and shutter release shock cause subtle vibration. a9, however has a vibration-free electronic shutter than can keep the camera stable, for razor-sharp images.

Swift, accurate, and reliable AF

Discover enhanced AF more precise, virtually unfailing focus, swift reaction to fast motion, low-light reliability, and consistent tracking in continuous shooting.

693. Remarkable number of phase-detection AF points

The phase-detection points on the surface of an image sensor 693 AF points covers approximately 93% of the image area. High-precision performance assures your focus on subjects.

Fast Hybrid AF achieves rapid AF for full-frame photos

Capture fast-moving subjects with reliable rapid AF. The speed and accuracy of this Fast Hybrid AF System are further improved in combination with the enhanced Bionz X image processing engine.

Reliable subject tracking in motion

Uninterrupted AF and optimised AF algorithm dramatically enhance AF accuracy and tracking. Even during shutter release, constantly activated AF lets you continue tracking random subject motion.

Eye AF for more precise focusing

Eye detection - enhanced by 30% through improved face detection - keeps the subject's eyes in focus, even if the face is turned at an angle or partially shaded. Wide focal-plane phase-detection AF sensor shows its ability in challenging shots.

Reliable even in low light

Capture subjects with high AF precision down to light levels as low as EV-3 at ISO 100, due to the high sensitivity image sensor.

Outstanding Image Quality

Full-frame 24.2-megapixel sensor with sensitivity up to ISO 204,800 and wide dynamic range captures outstanding image quality.

New CMOS sensor for imaging excellence

High sensitivity, a back-illuminated configuration, gapless on-chip lens architecture, and other Sony innovations deliver stunning images in a wide range of photographic situations. Standard ISO range is ISO 100-51,200 - expandable to ISO 50-204800 with minimum noise.

Technology for high-quality images

Utilise high-quality imaging that unites all available image sensor technologies - including back-illuminated structure, gapless on-chip lens architecture.

Bionz X enhanced speed image processor

Enhanced image processing combined with new front-end LSI reduces noise while improving detail depiction over a wide sensitivity range. Improved detail rendering enables lifelike texture reproduction.

Uncompressed 14-bit RAW

This file type is a good choice in situations where the sensor's wide dynamic range and fine gradation reproduction will benefit the images being captured.

High-resolution quality of 4K movies

Full-pixel readout with no pixel binning makes it possible to condense approximately 2.4 times the amount of data required for 4K (the equivalent of the amount of data required for 6K) into 3840 x 2160 4K output.

This oversampling process plus full-frame pixel readout without binning results in the highest possible 4K movie image quality.

Efficient workflow and professional reliability

In addition to a magnesium alloy body that assures the cameras all-around toughness and reliability, largely amplified versatile features enhance operability, supporting severe usage in professional photography.

Quad-VGA OLED Tru-Finder

The new high-res 3686k-dot electronic viewfinder shows a clear image with fine detail. The legendary ZEISS T* coating greatly reduces reflections.

Smooth EVF images realised by 120fps frame rate even allow you to easily track a subject in fast motion. Fluorine coating on the outermost lens provides improved protection from dirt.

5-axis Image Stabilisation

New body-integrated 5-axis IS unit offers a 5.0 stop shutter speed advantage. The live-view monitor image is also stabilised, so you can compose images easily even when shooting a fast-moving subject.

Battery Stamina for Professional Use

A newly developed NP-FZ100 battery offers approximately twice the life of the previous battery found in the a7 family of cameras.

Capture up to approximately 480 shots on one charge - and further increase by adding the optional vertical battery grip that can hold two batteries.

FTP File Transfer

A new terminal for wired LAN connection lets you transfer still images to an FTP server for viewing and management. FTPS is also supported so image files can be encrypted while being transferred (ideal if you are James Bond for example).

My Menu & New Menu Interface

A new My Menu feature lets you register up to 30 menu items for instant recall, arrange items in any order, and erase unused items. Also, primary menus have been reorganised for smoother search and operation.

Our Verdict

It is fair to say that Sony's range of mirrorless cameras has helped to change the face of the modern camera industry.

The Sony a9 is going to stand at the forefront of this already heralded range, and does so by using a whole host of new and improved features to bridge the ever shrinking gap between Mirrorless and Digital SLR cameras.

Whilst they aren't the only company attempting to do this, they are doing it with such aplomb and addressing what some see as the issues of mirrorless camera ownership.

The a9 for example features a new and improved battery, with a whopping 2.2x the capacity to former models - making it capable of over 480 shots with the EVF in use.

Which segues nicely on to the 3686k Electronic viewfinder - the resolution now becoming so high that the argument against EVFs is actually turning more into an argument as to why we shouldn't all be using them. One huge benefit being live view showing you what your exposure will actually look like based on the settings you are using on your camera.

This is aiming to capture the Pro market, and added features such as; Dual SD Card slots (one of which is capable of writing to the faster UHS-II standard cards), the aforementioned larger battery and most of all speed.

With its 24.2 Megapixel full frame stacked CMOS sensor, the ability to capture 20 fps in burst mode using AF/AE lock is a game changer. Adding speed as well as sublime quality to their range of mirrorless cameras is something that many have doubted in the past.

Sony proved with the a7s ii that the war for camera supremacy isn't won by a larger megapixel count, and the 24.2 MP sensor follows in the footsteps by delivering outstanding quality and low-light ability up to ISO 51,200.

With an ever expanding range of exceptional Sony E-mount lenses, from both Sony and  Zeiss lenses, the temptation to move to mirrorless is becoming even greater - and the application for sports and wildlife photographers is now becoming a reality.

We Love

  • You can take 20 shots quicker than you can read this sentence
  • Greatly improved battery life for shooting more photos on a single battery
  • EVF resolution up there with the market leaders for sublime viewfinding
  • Movie recording oversampled at 6K for highest 4K quality
  • Pro features make this a truly professional level mirrorless camera
