Que c'est complique cette photographie digitale ! Thanks for the interpretation. I'll have to reread it a few times. By the way, I need to find the accents somewhere in Yahoo.

I guess the physics teacher in you can get this change of perpective witout choking too much (wink) Of course, the 4/3 have other issues, this I cannot in fairness deny, but micro 4/3s seem to open many roads for lovers of older time lenses, name it, you can fit it...
