I've taken a few photos of different cameras I've used/had my hands on. I use a T420 much of the time, but have an E series for a back up. You can look at some images of various cameras here https://plus.google.com/u/0/b/117719861 ... 6547295169 When you click on a pic, you can then click on "photo details", to see what camera was used. After using / having a few, I'd say a combination of resolution and sensitivity is king. For example, my first camera a E40BX had lower resolution than a B60, but pics were/are better and was no comparison in the field, and the E Series has same resolution as the T Series camera I have, but there's no comparison IMO. The MSX is handy for panel scans, but I turn it off while scanning buildings myself..
