The i600 is a compact, economical speedlight with TTL and HSS capabilities, as well as a solid GN60 output and 24-200mm zoom. Available in fits for Canon, Nikon, Sony, Fujifilm and Micro Four Thirds, this flashgun is just 11.2cm high and weighs 300g without batteries, making it one of the smallest and most lightweight in its performance class. The built-in high speed sync functionality supports up to 1/8000s shutter speed, ideal for open aperture shots such as portrait with background blur, or high speed sports photos, even in bright ambient light. Various slave settings offer flexible optical wireless flash options, and the beam angle can be adjusted automatically or manually from 24 to 200 millimetres, according to the angle of the lens being used. The flash head is equipped with a built-in diffusor that gives 16mm coverage, and a bounce card that can be extended and retracted even when a soft box is being used. The flash head can be rotated left-right 180 degrees, and up 90 degrees, allowing photographers to bounce the flash off nearby surfaces for softer, less direct light. The simple-to-use dial system on the back mirrors the functionality of the i40, with one dial for Mode and another for EV. With clear controls and three indicator lights, even beginners can get started quickly. Flash output can be corrected up to +/- 2 EV in ½ step increments, making this flash a great option whether shooting in a studio or outdoors. Ideal for compact cameras, this flash measures 112 x 73 x 98mm, and operates on 4 AA batteries, with each new set of batteries lasting for 220-1500 flashes, and a recycle time of between 0.1 and 5.5 seconds, depending on the output used. This flash also features overheat protection and energy saving mode for maximum battery and product longevity.
