Looks like system resolution to me, expressed in megapixels.
Still doesn't tell one anything, because it will be different for each camera, and is still not comparable unless one converts it to real resolution. I have been workinh on a metric to be able to compare lenses more or less independently of camera brands, although medium (i.e., sensor) size is a factor still. I may post a few results yet <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt='

In the past it was much easier: we always used the same film and development techniques, based on photographs taken exactly the same way <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt='' />/>. I reckon they are trying to create something similar, and yes that is kinda based on human eye acutancy etc., because it is a metric based on system resolution, which by default is measured agaianst a general standard. I just wonder what their exact criteria are.
Warm regards, Wim
