[Leica] Macro Comparison Leica v. Yashica

[nicholsj at edge.net (Jim Nichols)]

Douglas,
Some of the advantage credited to the 55mm lens may come from its greater
depth of field which will be an advantage when photographing a curved
subject, such as this lamp.  However, I agree, that the Leica lens gives a
more rich color rendition.
