If you have a Pentax DSLR then this is the flash you are looking for. I was really debating whether I should go for a cheaper flash for off-camera use with a flash-activated on-camera optical slave, or rather get a 360 which gives me more options, especially when used on-camera. I am very happy that I chose Pentax. I'm so glad I ended up buying a second one. This is a good all round flash, easy to use and definitely great to use in combination with a Pentax DSLR. If you have two, you can use one on-camera to activate the other off-camera. Or use both cameras off-camera, activated by the on-camera flash (put the 360s in Slave 2 mode if you have a K100D). They have a built-in optical slave, so you don't have to buy anything extra. When used on a camera, you also have the option of very high synchronization speeds. Relax! My only gripe is that the battery door doesn't close as tightly as I'd like, so you'll need to check from time to time to make sure it's fully closed. A battery indicator would be nice too. Otherwise there are no real complaints. Good flash for the money. If you plan to use it off-camera a lot (strobist style) you can get a cheap off-camera radio sync system like Cactus-Trigger. But you don't need it right away. Experiment with optical triggering and see if it works for you. Good luck and happy shooting.
