The primary price drivers are the sensor size (Full-frame vs. APS-C), megapixel count, and processor speed. Full-frame sensors are significantly more expensive but offer superior low-light performance. Additionally, video capabilities (4K at 60fps vs. 1080p) and autofocus points (e.g., Dual Pixel CMOS AF) directly correlate with higher unit costs. For bulk buyers, understanding the shutter life rating (e.g., 100,000 to 400,000 actuations) is critical for determining the long-term value and depreciation of the asset.
