I recall posting about this just after I got my first 77. I thought it was
an amazing lens for general photography, but I absolutely hated it for
After looking at many pictures that I shot with it, I decided that what I
didn't like was, for lack of clearer terminology, it had too much
microcontrast, and was just too damned sharp.
However, what I did really like about the 77 is it's bokeh rendering. I
think it was Alan Chan who noticed (and immediately dismissed the lens as
garbage for it) that it has a fair amount of spherical abberation at wide
However, it does allow the lens a very nice bokeh, and a 3 dimensional look
to images taken with it.
Just watch out for specular highlights, they can go a little odd.
With most lenses, to get that 3D look in portaiture I am having to use a
skim light to seperate the subject from the background, with the 77, I get
most of the same look without the extra head.
The 31 shares a lot of similarities with the 77, high sharpness, lots of
contrast and excellent out of focus rendering.

The DA*55 is the 77s ugly brother. It's big, it's plastic, it's kinda
unwieldy, but damn, it's got some happening glass in it.
Think of it as a 77, but a little faster and 30% shorter.
