Kraken sports has introduced the compact and macro-focused KR-S40 strobe, offering a minimalist design ideal for underwater photography. Unlike larger, more powerful flashguns, the KR-S40 emphasizes simplicity and functionality, making it a suitable choice for macro shooters. Its user-friendly features include a straightforward control setup, white and red constant lights, and compatibility with various accessories like snoots. While its 40 watt-second output may not suffice for wider shots, it excels in macro settings, producing sharp, well-defined images. Despite some limitations, such as abrupt power adjustments and a cooler color temperature, the KR-S40 proves to be a versatile and reliable tool for underwater photographers seeking high-quality lighting solutions.
