I'd like to hear any comments on Sekonic L-508 exposure meter. It seems like a very capable device, even too capable for average user IMHO. Is it worth investing in that piece of equipment (I mostly use F5 RGB meter)? What other meters are also good for tricky light situations, Minoltas, Gossens? For a little over $400 I can buy a good lens so I really need to know when and how to use external exposure meter. Tanx a lot! [EMAIL PROTECTED]
