I already explained and discussed with you and others in details here and in other threads what the problem was and you compared the shots you took in manual compared to skiers when you a tight plane of focus which is a complete different thing. I shoot manual focus since 12y and I know what I'm talking about.
The NX lens lineup is limited and will never be expanded and the lens available are not as assicurate as DSRL and probably impossible to buy. What is there more to say? I said I personally wouldn't use this system for stills only if planning to use on a variety of situations.
Le'ts just drop this topic, I'm just tired.
