I think it would be very helpful to note focus accuracy without nit picking between different cameras ability to track. There are plenty of cameras that seem unable to focus well (i.e, either too much tolerance for 'focus correct' or sensor mark too broad for precise focusing - which is more important for close up).
Anyways there is a bit of conflict here since it sounds like a formal analysis is very difficult and the review attempts to do a formal analysis; yet accurate focusing is such a key ingredient to any camera. Oddly with all the complaints I found the E-3 focus to be more 'accurate' than the canon 450D. What this statement really means is that I notice more shots being off with the 450D (not consistent front/back focus) than I did with the E-3 and I don't believe this is due to dof issues one would expect with the E-3 smaller sensor.

Hum. Oh well I guess the problem is want (good description of camera focus accuracy) versus having a practical solution on how to provide.
