Pixel X-800C is a new generation speedlite which is completely redesigned by Pixel. Although the X-800C may appear to look similar to Pixel’s Mago Flash, now resembling much more the original Canon 600EX-RT design. The flash head is smaller than the Canon 600EX-RT. The full power recycle time is about 2.5 seconds only. The firmware is upgradeable via the mini USB port. With its long life flash tube and energy saving techology, the flashgun life has been significantly improved.
