Slim enough to slip into a shirt pocket, the Sony HVL F20AM is an ideal add-on for anyone who wants an extra light source to supplement their camera's pop-up flash. Weighing less than 100g, the smartly-styled HVL F20AM can fold down to keep a low profile when it's not being used. Just pull the flash head up ?it's powered up and ready for use whenever it’s needed. The Sony F20AM also comes with a handy switch to select Bounce flash operation. This gives indirect lighting for more natural results with portraits and other subjects that can get bleached out by direct light from an inbuilt flash. The HVL-F20AM can also double as a wireless flash controller to be used as an inexpensive trigger for wireless remote flash heads.
