I have been using the QX10 for a while and now I have the QX100. Both have been used now with the 5S. I have the QX10 review live on my blog already. Goto my blog, use the index tab, reviews , QX10 , or search on blog QX10. On Tuesday I have the photo comparisons and Wednesday the QX100 review. If you have any questions please ask away. I will keep this thread updated with any developments and third party apps that support these lenses too. And below are the bad boys.
