A9 review

Body and handling

The first thing to note is that the Sony a9 feels light and compact thanks to its magnesium alloy body.

The camera body weighs a total of 673 grams without lenses. It feels solid to touch and easy to hold and handle. Since it lacks a desired vertical grip and it's pretty compact, it might be uncomfortable for photographers with larger hands.

You may purchase an external grip for increased comfort and stability.

Durable weather sealing

The durable body is weather-sealed but features no rubber seals to protect the various openings and elements from a rainy day or a splash of water.

This mirrorless camera features several handy top deck dials. You can adjust the burst speed, shot style, AF mode, and more.

The dials offer practicality and handle intuitively. The complete menu, however, does almost the opposite.

Not beginner-friendly menu system

With dozens of functions hiding in the complex menu system, this camera is a challenging choice to pick up for the first time. This is partly offset by the high degree of customizability with three buttons and a dial with the ''Recall Customer hold"" function.

Now, you can override your camera settings and apply a previously registered specific mode in the blink of an eye! This makes switching between your preferred settings a breeze after the initial setup.

Multiple shooting angles with 3-inch tilting touchscreen

The 3-inch tilting touchscreen is efficient when shooting at every angle. It provides a seamless experience with no distractions.

It produces no screen blackout when taking a shot, which is a considerable improvement.

Image quality

The camera features a spectacular stacked sensor, which proves to be an advantage on several accounts.

Firstly, the engineering of the electronic shutter allows the sensor to read data 20 times faster than before.

The Sony Alpha a9 shoots at a staggering 20fps for 362 jpegs or 241 RAW files. You can shoot with a wide-open aperture, even in direct sunlight.

Outstanding AF system with 600+ focus points

This is where the a9 really shines!

The mindblowing AF system features over 600 focus points and a multi-selector joystick to control the focal point. The Eye Focus mode works stunningly through excellent facial recognition and precise subject tracking capabilities.

The handy AF-ON button allows for back-button focusing, giving you complete control. The stacked CMOS sensor also contributes to the improved AF and boosts noise performance.

Native ISO range of 100-51.200

The camera features a native ISO range of 100-51.200, excellent for various shooting conditions. The autofocus performance staggers slightly in very low-light conditions but is still decently capable overall.

Steady imagery with 5-axis IBIS

A 5-axis internal stabilization system ensures that your shots stay steady even at extremely fast exposures.

It's efficient and reliable, making working with the subject tracking function a cakewalk.


The Sony Alpha a9 has the expected Wi-Fi, NFC, and Bluetooth connectivity.

It includes a Micro USB 2.0 port. It also features a flash sync socket for high-speed image transfers.

As well as having the usual credentials, the camera features a flash sync socket and Ethernet port, allowing for a speedy transfer of images.

Sony Alpha a9: pros and cons

Every pro knows that even outstanding cameras don't come without a compromise.

The main factors to be mindful of with this camera are as follows.

3 Advantages

The camera has a lot going for it, but some specs and features stand above the rest. Here are the best things about working with a Sony Alpha a9:

1. Impressive autofocus

The camera's impressive AF offers 93% coverage and reliable subject tracking even at a breakneck speed.

The dedicated joystick makes it easy to set the focus point on the fly, letting you keep everything sharp in the frame if you decide to do so.

2. High-resolution viewfinder

The Quad-VGA OLED Tru-Finder is a high-res and luminous viewfinder with a 120fps refresh rate.

The lack of blackout with the help of the electronic shutter is a transformative shooting experience even at a 20 fps burst rate.

3. 5-axis IBIS

The 5-axis image stabilization is an absolute gem for anyone dabbling with action or sports photography.

This advanced system is reliable and provides a shutter speed advantage of 5-stops, adding to the staggering burst speed.

3 Disadvantages

For an authentic review, the shortcomings and challenges of the model can't be ignored.

Whether you can put up with the following disadvantages is up to you.

1. Passable battery life

While Sony finally upgraded their old NP-FW50 battery to an NP-FZ100, the around 480 shot battery life won't impress creators working long days.

As with most mirrorless cameras with an EVF, the a9's luminous viewfinder drains the battery significantly. By switching it off, you can boost the expected battery life to 650 shots on a charge, which amounts to about 12 hours of diligent work, give or take.

Having additional batteries can always save the day.

Invest in a few FZ100 batteries to be good to go on even on the longest of days.

2. Overwhelming menu

The camera's menu is reminiscent of a puzzle or labyrinth. It takes a while to figure out, but it is certainly rewarding!

Lucky for you, this mirrorless offers a remarkable degree of personalization. You can create a simplified menu with only your favorite settings and functions.

3. No comprehensive weather sealing

The lack of rubber gaskets around the a9's various openings is scary in any slight drizzle or high humidity.

The camera sometimes struggles with condensation buildup that can damage the internal components.

Overall, the weather sealing is simply unable to withstand anything more than minimal contact with water.
