The Bower SFD14S is a specially designed lighting solution fit for a variety of uses. Specifically made for Sony digital SLR camera bodies, the unique shape of this Bower ring light is a big part of its charm. The light source of the digital macro ring flash is the circular tube, which delivers evenly balanced lighting to accommodate projects ranging from sensitive dental and medical procedures to simple flash photography projects around the house. A TTL dedicated unit, the Bower SFD14S truly excels in short distance scenarios where the smallest changes in lighting can make the biggest difference by adding impressive accuracy to the final outcome. Its TTL tethering also takes the guesswork out of finding the right exposure while simultaneously helping address common issues such as red-eye and shadows. This Bower ring light has a guide number of 46 and accommodates a broad range of coverage in terms of lens filter size. The unit attaches directly to a 52 mm lens, but includes adapter rings that allow it to support filter sizes of 55 mm, 58 mm, 62 mm, and 67 mm. For photographers, the lens flexibility of the digital macro ring flash comes in handy for finding that perfect shot. Additionally, the bounce and swivel of the head gives it the ability to easily adjust to the most challenging of lighting conditions. Whether it is hobbyists' adventures or demanding professional applications, the Bower SFD14S provides optimal illumination when conventional flash will not do the job.
