Hi,
I just wanted to give some input on these lens tests.
IMHO, if we do create a database of lenses "fit for use on G1", we can not limit ourselfs to "looking if the image fills the sensor". We also have to care about other parameters such as resolution (if not why do we have MP sensors in our cameras ?), distortion, aberration (sferical & chromatic), flare, ghost images, diffraction, ..
And we have to do so in a coherent manner, Peter should test his lenses the same way as Bill does, etc.
Test patterns for lens test do exist, they are available for download from several sites, however, mainly not free of charge. But we could make something for ourselfs. It is not very important what it is or how it looks like, but it has to be the same for every tester.
Also, we need to define standard test conditions, like : camera on a tripod, exposure time 1/60, HQ jpg setting, ... so that "shaky hands" or postprocessing do not influence the results etc.
If we are ready to go down that road, our database will be a useful one.
Otherwise, people spending money based upon our "recommendations" might become very unhappy visitors at this forum.
