I was thinking about Amin's work on DR the other day, and it got me on this strange tangent. I've been trying to come up with a convenience factor (someone else please name this). Using OEM specs, I took the VOLUME of the body of the camera, and divided it by the AREA of the sensor. No lens, no weight factored in. It kinda makes sense, smaller body with a bigger sensor might be considered by most to be preferable to a large body with a tiny sensor (...reasonable?). This is for sh*ts and giggles, BUT if we could work out a standard, it might catch on! Posting it here, I'm declaring it is now this site's creative property, so all you other sites beware, this is OURS (LOL!!). The lower the number, the better the image quality for what you have to carry to get it (please feel free to word this, too). Here are the first four I ran: Leica D-LUX 5 Convenience Factor (CF) 155 Nikon D3100 Convenience Factor (CF) 97 Canon EOS-1Ds III Convenience Factor (CF) 88 Olympus E-PL2 Convenience Factor (CF) 60 I'm in marketing... therefore my ego died a long time ago. Feel free to make this better, just be constructive. It kinda makes sense, right?
