Adequate for documentary photos. Lacking for artistic quality. Very much like my favorite pair of shoes, sweatshirt, hat etc. The very best for my use even if they are not pieces of art. The coming DSLR can make them artistic. (i.e done with skill)
In #3 you can see the glass, 4 is my fav. I like the concept of 5 but not digging the photo too mucho. and 6 i would love to see not the curve of the street, but straight street, so you can see far in
