Rx100 clearzoom - is it usable for printing?

I would say printing is its strong point. The images look good. I have mine set to a 20M large file.

I think on screen they look good as well .... except for tghos who insist on peeping at 200% to look for differences.

ity does seem a genuinely good option for JPG shooters except that once to get past x3.6 (i.e. normal zoom) you lose control over the metering and focus setting but I think that would only matter if shooting against a brightly lit background and you would prefer to have chosen spot metering. Overall, it is very good and not like any digital zoom that I have experienced before.
