I'm pretty new to the camera world, but love taking pictures as a hobby. A friend of mine has asked me to take some pictures of his new product that he will be launching. The shots he's looking for will be close ups but not macro shots. I have a GF1 with the pancake lens and am looking for a flash gun compatible with the GF1. I plan to purchase a wireless receiver so I can control my lighting at different angles and such. Does anyone have any particular favourites they can share or recommend that would be compatible with the 4/3 camera?? Thanks!
