Dave, preference is one thing, acknowledgement that Olympus is in a camera and lens system not completely of its own making is another. It is fine to prefer one brand or another, but perhaps a misnomer to talk about the Olympus "system" as if the other companies in the m4/3rds camera and lens system, including Panasonic, do not exist. I have no doubt that Kevin is aware that m4/3rds exists, but he seems reluctant to mention it for reasons of his own. I cannot force him to do that, but think it would be better if he did. This seeming reluctance over a few posts about Olympus finally led me to comment. Now perhaps we can get on to other things like photography, and enjoy whichever camera we prefer to do it with.
