Sigma SD15 Pros and Cons
Now, we will look more closely at our review of the Sigma SD15 camera. We will see what it can do and compare it to other cameras like it. We will tell you what's good about it and what's not so good. This way, you'll know if it's the camera for you!
Build and Construction
Body and dimensions
|Dimensions||144 x 107 x 81mm|
The Sigma SD15 is not sealed against water and dust, so it's important to be careful when using it in such conditions. If you often shoot in environments with water or dust, it's recommended to check out another camera with weather sealing.
Design and Handling
Main design features
|View Finder||Optical (pentaprism)|
|Screen Type||Fixed Type|
|Screen Resolution||460k dots|
|Body type||Mid-size SLR|
This camera has a fixed type 3.00" screen, with a display resolution of 460k dots. This makes the Sigma SD15 not as suitable for those looking for a vlogging camera as you cannot view yourself while shooting selfies easily. Unfortunately, the camera does not have a touch screen, which may make it less user-friendly.
SD15 includes a optical (pentaprism) viewfinder with no electronic viewfinder of resolution with a coverage of 96% and a magnification of 0.6x. This feature enhances the camera's suitability for outdoor photography in bright conditions.
Sigma SD15 has a 5MP sized CMOS (Foveon X3) sensor. You can shoot at maximum resolution of 5 pixels. Sigma SD15 has a native ISO range of 100 - 1600 which can be boosted to 50 - 3200. It can also save files in RAW format which gives you a wider room for post processing.

DXO Sensor Scores
Low Light ISO
DXO mark sensor scores
The DXOmark rankings indicate that the Sigma SD15 camera has excellent color depth performance, which refers to the number of colors the sensor can distinguish. Additionally, its dynamic range is also excellent, allowing it to retain high amounts of details in both bright and dark areas of a scene. The camera's low light ISO performance is excellent, which is an important factor to consider if you plan to use it in dimly lit indoor environments or at night. Overall the image quality of the SD15 is excellent
Camera crop factor (or focal length multiplier) refers to how a camera's sensor size affects the apparent field of view of a lens. Crop factor is determined by comparing the size of a camera's sensor to that of a full-frame sensor, which is a standard reference size for camera sensors.

Connectivity, storage, battery
The Sigma SD15 supports SD/SDHC card 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 Sigma SD15 uses the undefined model of undefined. This is rated for undefined 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.
The Sigma SD15 has built in flash which is great for event photography and in low light situations. It also offers a flash shoe that allows you to attach external flashes. This provides more versatility in your lighting choices.
The Sigma SD15 boasts a maximum mechanical shutter speed of 1/4000s, 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 Sigma SD15 includes two autofocus (AF) systems: contrast detection and phase detection, with null 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.

No the SD15 does not have weather sealing.
The Sigma SD15 was announced on Feb 20 2010
No the SD15 does not have in-body image stabilization that can compensate for camera shake, making it easier to shoot handheld in low light conditions.
The SD15 has a native ISO range of 100-1600, which can be expanded to ISO 50-3200 for even greater sensitivity in low light conditions.
