In considering a flash attachment for my GF1, but am totally confused by the options available. The Panasonic FL220 doesn't swivel or tilt but price is nice, the FL360 tilts and is priced ok and last but not least is the FL500, the most expensive of the lot. There are complaints that the 360 and the 500 are too big, making use of the camera with them attached difficult. I definitely want a flash that tilts and that will work on the hotshoe with the camera. Are there 3rd party flashes out there that work well with the GF1 and are not so big as to over-power the camera and make holding it difficult? Also, interested in what you may be using and why?
