I am going to buy a wireless flash for my Canon 650D camera. I've got two lenses, the Canon 18–55mm kit lens and Canon EF 50mm f/1.8. I am not a newbie photographer and know how to use my camera well. My main intent of buying a flash is for food photography in which I am very interested. Of course I might be able to use wireless flash for taking more beautiful portrait, indoor and outdoor photos as well when I become more pro at using it. Now I have to choose either 320EX or 430EX. I've read this review which compares the two models but still need your advice to decide which one to buy.
2 features make the 320EX unique: its built-in video light, and the camera remote control
I don't think I need the built-in video light very much. I also do not know how handy would be a "camera remote control" on the flash. 320EX has this remote control, while 430EX does not. The review says that 430EX is suitable for “strobist” photography of which I'm not much aware. The 430EX has more power, esp. with tele zooms. I do not have any tele zoom lens and do not think will have such lens in near future, so I don't think I need more powerful flash light. 430EX has a built-in LCD screen and again I don't know how necessary it is. 320EX is only a little cheaper than 430EX, so the price is not a factor for me. Any advice on helping me to decide which one to choose would be greatly appreciated!
