What You'll Learn
Sony A7III's battery life
The Sony A7III is a full-frame mirrorless camera that uses Sony's new, longer-lasting NP-FZ100 batteries. These batteries have a capacity of 2280mAh and should deliver, according to CIPA ratings, up to 710 shots on a single charge when using the LCD screen and 610 shots when using the EVF. In practice, you may get a considerably larger number of photos from a single charge, especially when using a burst-shooting mode.
The battery life of the Sony A7III is a significant improvement over its predecessor, the A7 II, which used the much smaller capacity NP-FW50 battery. The A7II battery only had a capacity of 1020mAh and delivered just 340 shots using the LCD and 270 using the EVF.
When shooting a wedding with the Sony A7III, the number of batteries you need will depend on how long the event is and how much you are shooting. If you are shooting all day, you will likely go through at least one battery, and if you are shooting a lot of video, you may need more than two batteries. For a 10-hour wedding, some photographers recommend having 4-6 batteries on hand.
To extend the battery life of your Sony A7III, you can use the optional VG-C3EM Battery Grip, which doubles the battery life and holds a pair of NP-FZ100 batteries. Additionally, putting your camera into Airplane mode can help conserve battery power.

Sony A7III's touchscreen capabilities
The Sony A7III is a well-rounded camera suitable for both photo and video applications. It features a rear touchscreen that can be used for Touch Focus control. A Touchpad Focus Control mode lets you use the rear screen intuitively while keeping your eye on the viewfinder. The touchscreen LCD is part of the camera's revised body design, which also includes an improved EVF, larger battery, and dual memory card slots.
The A7III's touchscreen capabilities allow users to adjust the focus point by touching the screen. This can be particularly useful when shooting moving subjects or when using the camera in different working situations. The touchscreen can also be used in conjunction with the camera's 5-axis SteadyShot INSIDE image stabilization system, which compensates for five different types of camera shake during handheld shooting.
While the touchscreen on the A7III offers some useful functionality, it is not a fully-featured touchscreen in the sense that it does not allow for both focus and shoot on the screen. Users have reported that the touchscreen can only be used for focus control and not for capturing images. This is a compromise often seen in photography equipment, as other factors, such as the camera's compact size and tilt-out screen, may be more important to users.
It's worth noting that the absence of a touchscreen on high-end cameras is not uncommon. Touchscreens are typically associated with consumer-level cameras, while professional cameras often rely on buttons and knobs for more efficient control. This allows photographers to build muscle memory and focus on capturing the image without being distracted by the mechanics of the camera.

Sony A7III's low-light performance
The Sony A7III is a powerful camera that performs well in low-light conditions, making it a great choice for wedding photography and videography. Its ISO range is from 100 to 51,200, expandable to 102,400 for video, which means it can capture clear and sharp images even in dimly lit environments.
The A7III has a Sports (low-light ISO) score of 3730, which is extremely impressive and puts it ahead of competitors like the Nikon D850 and Canon EOS 5D Mark IV. This makes it an ideal camera for fast-paced, low-light situations such as wedding receptions or events.
One of the key advantages of the A7III is its ability to manage noise levels effectively, even at high ISO settings. This results in cleaner images with less grain, which is crucial for low-light photography. Additionally, the A7III has a dynamic range of 14.81 EV, which is very similar to the impressive Nikon D850's range of 15 EV.
To get the most out of the A7III in low-light conditions, consider using a fast lens with a low aperture like f/1.8, which will allow more light to reach the sensor. This can help you avoid increasing the ISO too high, which can degrade image quality.
Overall, the Sony A7III is an excellent choice for low-light photography and videography, offering impressive ISO performance, dynamic range, and noise management. Its low-light capabilities, combined with its long-lasting battery life, make it a versatile and reliable camera for capturing the magic of weddings.
Regarding batteries, it's important to ensure you have enough power to last through the entire event. The batteries for the A7III are said to last around 1.5 hours each, so for a typical 10-hour wedding, you'd need about 6 to 9 batteries if you don't have a chance to charge. However, if you're primarily taking photos, you may get away with fewer batteries as one user reported taking 2400 photos with a single battery. It's always better to have more batteries than you need, so aim for at least 4, and consider investing in a compact power bank for added peace of mind.

Charging the Sony A7III
The Sony A7III is a powerful camera with an impressive battery life. It uses Sony's new, longer-lasting NP-FZ100 batteries, which offer an improved capacity over previous models.
When it comes to charging the Sony A7III, there are a few options available. The camera comes with a dedicated battery charger, the Sony BC-QZ1, which can fully recharge a battery in approximately 150 minutes. This method is convenient and ensures a consistent charge.
Another option is to charge the battery in-camera via the USB-C port. This method is useful when you're on the go and don't have access to the dedicated charger. However, it takes longer, with a recharge time of approximately 285 minutes.
It's worth noting that the battery life of the Sony A7III can vary depending on usage. When shooting stills, you can expect to capture around 1500-2000 shots on a single charge. The battery life for video recording is approximately 2 to 3 hours. If you're shooting a lot of video, you may go through more than two batteries in a day.
To maximise battery life, consider enabling Airplane mode and turning off any features you don't need. Additionally, using the camera in colder temperatures can impact battery performance, so be prepared to swap batteries more frequently in cold environments.
It's always a good idea to have spare batteries charged and ready to go, especially if you're shooting a time-sensitive event like a wedding. By planning ahead and understanding the battery life and charging options of the Sony A7III, you can ensure that you're fully prepared for your next photography or videography adventure.

Sony A7III's auto-focus capabilities
The Sony A7III is a powerful camera with impressive autofocus capabilities. It features a sophisticated and intelligent focusing system, boasting 693 phase-detection autofocus points and 425 contract-detection focus zones, enabling it to deliver exceptional speed and tracking performance.
One of its standout features is Eye AF, which automatically detects and focuses on human eyes within the frame. This makes it ideal for portraits, ensuring that the subject's eyes are always sharp and in focus. The camera can even maintain focus on the eye area, even if the subject blinks or moves their head slightly.
The A7III also offers Continuous AF, which allows it to keep up with moving subjects. This feature works well when the subject is moving towards the camera at a consistent speed and angle. Additionally, the A7III has a wide autofocus area, covering 93% of the frame, enabling it to track subjects even when they move towards the edges of the image.
While the A7III excels at autofocus, it also provides the option of manual focus. The touchscreen interface simplifies the process by allowing users to tap on the screen to select the desired focus area. This combination of autofocus and manual focus capabilities makes the A7III a versatile tool for photographers and videographers alike.
In terms of battery life, the A7III utilises Sony's new NP-FZ100 batteries, which offer extended battery life compared to its predecessors. According to some users, a single battery can last up to 2-3 hours during a wedding shoot, but it's recommended to have at least 4 batteries for a 10-hour wedding to ensure you don't run out of power.
