Most controls are familiar: On top of the housing is located next to the famous LC status display the setting for the choice of exposure modes. The second wheel to the left of the viewfinder is used as an on / off switch and a choice of single or continuous shooting, self timer, mirror lock and auto bracketing solvers. Worth mentioning feature is the Quick Set button for direct access to frequently used functions. The most striking change concerns the display on the rear panel, which is now 3 inches tall and, with 153 000 RGB pixels, a very decent resolution. Conversely Equip Sigma also has the storage medium: the SD15 takes SD / SDHC and MMC cards optional on. With the equipment now includes a more powerful built-in flash (guide number 11).
Test Results Sigma SD15
The results are mixed. The SD15 confident with a constant limiting resolution of 1056 LB / bra over the entire measuring range. However, the noise increases at higher sensitivities for current camera too fast. Positively to the relatively low texture loss falls (0 to 0.5) on. Properly, the results in color accuracy and white balance (RGB 1 Delta, 6.8 DeltaE). The SD 15 is equipped with a twice as large buffer-memory-equipped as the SD14. Thus, while 21 images are now instead of 6 images taken in succession. When the burst speed has not done much here, however: The SD15 provides 2.9 frames / s, so that only 0.2 frames / s over its predecessor.
Conclusion: The Sigma SD15 is a slight improvement in SD14. The three-layer Foveon sensor and a resolution that is a good 8-megapixel camera is based, have remained, the noise is now slightly higher. The main innovation, the True II image processor in the laboratory could not score with significant improvements. Further developed has become the new primary in terms of features and comfort. Despite a large 3-inch screen but lacks a Live View function. Also videos can not capture the SD15.
