The small flash unit Godox TT350P Mini Thinklite TTL Flash is an excellent everyday companion for your camera as it is fully compatible with the Pentax TTL system, syncs at high speed, and features a built-in 2.4GHz radio system. Its lightweight design and guide number of 118' at ISO 100 at 105mm make the TT350P unit ideal for use on or off-camera. The user can also use it individually as an optical slave device as well as a radio TTL master/slave unit. The 270° rotation capability and the head tilt capability from -7 to 90° add even greater flexibility.
