I just have looked at Imaging-resource PMA report, and looked closer at new 4/3 lenses. They are big! For instance 14-54/2.8-3.5 (28-108 equiv.) has filter size 67 mm, while new Pentax FA 28-105/3.2-4.5 has only 58 mm having not that worse f range... I feel, that it is true, what most of PDMLers say - there's little chance that 4/3 system will be succesfull.
