While we own a Sony point-n-shoot camera, I wanted something that allowed me more manual control over the camera settings and most point-n-shoot camera lenses don’t have a wide enough zoom for landscape photography and the tiny sensors do poorly in low light. It seemed that a compact systems camera (CSC) was what I wanted. As usual I got distracted by shiny new things and quickly found myself looking at the high-end of this camera segment and forgot my original intent. Once I realized that what I was really doing is re-evaluating my current camera choice, I decided to see what I would do if I had to start all over and buy a new camera system.
There were a lot of options from Sony, Fuji, Olympus and Panasonic. But which was right for me needs (my expanded needs)? How do I compare between cameras for such variables as sensor size (micro 4/3 vs APS-C vs full-frame), sensor resolution, styling etc. I need to take a more scientific approach.
Making decisions requires comparing alternatives with respect to a set of criteria. If there are more than two criteria, determining which criteria are more important can itself be a serious problem. One would like to be able to rank the criteria in order of importance, and to assign to the criteria some relative ranking indicating the degree of importance of each criterion with respect to the other criteria.CISSP Online
This is a technique I’ve used in the past for making decisions about large purchases where there are many variables to consider. I used a criteria decision matrix to buy my current car and when I purchased my HDTV. It a technique I learned in a total quality management class in graduate school. But it’s been a while since I had to do one — my car was purchased in 2006 and the TV a year before that — so I did some research on Google to find a method I could use.

For this decision matrix I used a pairwise comparison matrix. My criteria are lens choice, sensor size, image resolution, ergonomic feel, styling and cost. I ranked each of the criteria according to how important they were to each other. It seems that, for me, lens availability — how may lenses are available for that camera from the manufacturer or third parties — and cost are the two most important factors. They are equal in importance to me. I limited my options to cameras that came out during PhotoPlus Expo in New York.
Each criteria was weighted and the weighting used in the decision matrix. I ranked each of the options according to how good I think they are at meeting the criteria when compared against my current camera, the Nikon D5100. Based on that it seems the Nikon Df is the camera I would buy when I’m ready to buy a replacement for my Nikon D5100.

But my original wish for a compact but capable camera for travel and vacations with the family was still unfulfilled. I have a few ideas on where I should look but no firm plans as yet.
