My main objective is to document places around the world for Google Earth. Some of the pictures are scans from old slides, but the majority is digital pictures.
I'm a Canon man! My old favorite was the T90, especially with the 50/1.2 and 85 1.2 lenses, but it is very seldom used nowadays because of the cost. I'm presently using the EOS 40D and 50D with quite a wide range of lenses.
PS. I still have my old Hasselblad 500C and Leicaflex SL2, but unfortunately hardly ever use them.
