By all means make your comments as your opinion and experience - that's actually really helpful. But make it clear that it is opinion, not unchallengable fact, or you will be challenged, because that really isn't helpful. And it's the same whatever format it is, and whatever manufacturer, as you would know if you looked in any of the other camera rooms (well, to be fair I can't recall the last one in the Minolta or Sony rooms) - it just so happens that in this case it's 4/3 because that's what we happen to be talking about. Don't even attempt to make my comments an attack on 4/3 or 4/3 users in general, they're certainly not, they're comments about somebody letting their enthusiasm get the better of what they write. Look, the OP has indicated that he's got some concerns in the area of low-light/high ISO performance. If you say the issue doesn't exist at all, what if the OP buys the camera as a result and then finds that he's not happy with it, as he has different requirements and perhaps standards to you? Have you then been helpful, or have you actually made things worse than if you hadn't answered? Whereas what Rob has done is to give the information and his opinion, and leave the OP to decide for himself - now that IS helpful, because the OP can make a judgement based on his own criteria. Forgive me if you think that's pedantic and patronising, because I think it's actually looking after the interests of our members - it's a matter of complete indifference to me what camera Chris buys, so long as he's happy with his choice. What I personally think he should do is make a shortlist based on his requirements and try them out and see what he feels most comfortable with - all we should really be trying to help him with is developing the shortlist.
