Don't be deceived by the Nissin i40's svelte dimensions: This mini-marvel packs a Guide Number of 40 at 105mm, video lighting adjustable over 9 stops (a real boon at special events at gigs, where you can freely switch between videography and still photography), and a specification replete with high-end features. Although perfectly proportioned for smaller DSLRs and compact system cameras, the i40 is equally at home on full size DSLR models, weighs only 203g and fits easily into a pocket. The flash head features 180° horizontal and 90° vertical rotation and is powered by 4x AA batteries (not included) - which provide sufficient power for over two hundred full-power flashes or three and a half hours of video lighting. Why weigh yourself down, when this little wonder does it all?
