Connectivity, storage, battery

StorageSD/SDHC/SDXC, Internal
Battery Life260 shots
Battery ModelD-LI92
Wireless Connectivity


The Pentax Optio WG-1 supports SD/SDHC/SDXC, Internal with 1 slots for storage. This may suffice for everyday use. However, for professional applications such as wedding photography, it is not recommended as a memory card malfunction could lead to the loss of all footage.


The Pentax Optio WG-1 uses the D-LI92 model of battery pack. This is rated for 260 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 Pentax Optio WG-1 has built in flash which is great for event photography and in low light situations. However it lacks an external flash shoe, which limits you to using the built-in flash.


The Pentax Optio WG-1 boasts a maximum mechanical shutter speed of 1/1500s, 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 Pentax Optio WG-1 includes contrast detection autofocus (AF), with 9 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.
