I was about to buy a Cokin P-Series Starter Filter Kit to use with my 14-42mm f/3.5-5.6 and 40-150mm f/4.0-5.6 Zuiko Lenses ....however I have been reading and it seems this filters may produce vignetting ..... is it true ?? also I read that the P series ND filters are not neutral ... does somebody use this cokin filters with this zuiko filters??
should I buy another brand???
thanks for the help!
