Best smartphones cameras 2015

GeoJot+ is photo-based field data collection, so camera quality is a concern for many of our customers. Below are links to 2 different articles about the best smartphone cameras this year.,review-2272.html

Both articles recognize the iPhone6 plus and Samsung Galaxy. These (or their recent predecessors) are the most common cameras we see among our customers. One of the articles also talks about the new Panasonic Lumix DMC-CM1.

I like the idea of this because some of our customers have more detailed requirements for their photos, however, I am not sure this meets those requirements. I initially assumed that the Lumix would have optical zoom but it doesn’t. If our customers have specific camera requirements it is usually around zoom so this may not be a better fit. These camera phones seem pretty rare, has anyone out there used one? If so, what did you think?
