Battery Life490 shots
Battery ModelNP-FM500H
Wireless Connectivity


The Sony Alpha A99 II supports Dual SD/SDHC/SDXC/MS Duo slots with 2 slots for storage. Having dual SD card slots on the Sony Alpha A99 II is highly advantageous as it mitigates the risk of losing footage due to memory card malfunctions. This feature is particularly beneficial for wedding photography and other professional settings.


The Sony Alpha A99 II uses the NP-FM500H model of np-fm500h lithium-ion battery & charger. This is rated for 490 shots shots which is high. If you intend to take photos or record videos for an extended period, it might be a good idea to bring along additional batteries.

Photography Features


The Sony Alpha A99 II does not have a built-in flash, but it does offer a flash shoe that allows you to attach external flashes. This provides more versatility in your lighting choices.


The Sony Alpha A99 II boasts a maximum mechanical shutter speed of 1/8000s, which is ideal for shooting fast-moving subjects in bright environments, such as in sports photography. Faster shutter speeds enable you to freeze the action and capture every detail, making it easier to get the perfect shot.

With a continuous mechanical shutter speed of n/a or an electronic shutter speed of n/a, this camera is not capable of capturing the perfect moment more easily, making it not as suited for wedding, sports, and wildlife photography. Higher shutter speeds make it easier to capture fast-paced action, ensuring that you never miss the perfect shot.


The Sony Alpha A99 II includes two autofocus (AF) systems: contrast detection and phase detection, with 399 number of focus points.

While contrast detection is generally more accurate and precise, phase detection autofocus is faster and more effective in most situations, particularly when photographing moving subjects.

Phase detection autofocus works by dividing the incoming light into pairs and then analyzing how they intersect on the camera's sensor. This method allows the camera to determine not only if a subject is in focus but also the direction and distance needed to adjust the focus to achieve perfect sharpness.

On the other hand, contrast detection autofocus works by analyzing the contrast of an image and adjusting the focus until the highest contrast is detected. While this method is very accurate, it can be slow, especially in low light conditions or when photographing moving subjects.
