John, the 398 is just a slightly updated version of the L28c2. Basically the same thing with a couple of small differences.
So from what others are saying, there is no telling how accurate the L28 (?)is and maybe I should go and get a 308. My question at this point is, will one of these incident meters work for landscape photography? Or are they only for portraiture photography? Being retired I do not have a big budget for the latest and greatest equipment so that is why I'm looking at older used equipment for film.
Thanks
