The mecablitz 44AF-4 is designed to also be fully compatible with Digital cameras. The flash features the Double Cobra fresnel pattern for a more even distribution of light with significantly less redeye, and there are some logical changes from its 40MZ-3i predecessor: the ability to display the working aperture upon the LCD screen and an 'extended zoom' mode which keeps the flash coverage a bit wider than the focal length for better peripheral illumination. It is a great all-purpose medium class flash for advanced amateurs.
