DA* 16-50mm Serial Number Database.

Just wondering if anybody can provide some pictures to show how they are supposed to be looked like from a good 16-50mm lens? I've tried 3 16-50mm lenses so far but all of them gave me not very sharp pictures when shooting at 50mm f/2.8, about 5 meters from the object. I also
tried them a few times at a book store, took a few shots at 16mm f/2.8 in front of a book shelf , the pictures looks blurry at 100% zoom. Sometimes they do work pretty well when furthur stopped down, or even at f/2.8, I can get some really sharp pictures if I'm close to the object. This lens is so confusing.

A picture taken at f/2.8 16mm, and let's say, it's soft on both sides. I keep telling myself, isn't that normal?
I checked some other lens reviews such as nikon 20-35mm f/2.8, it has the same problem too.
I mean, a brick wall picture with blurry image on both sides really means the lens is bad?

K10D LCD glitch?

Hi, I found the picture is brighter when I tilt the body sideway (lens upward or downward),
this doesn't happen on my friend's k20d, does anybody else have the same problem?

This is probably not very big issue but since I'm new to dslr so I rely on the screen a lot,
my ev is always at +0.3 so the pictures won't look too dark.

Thanks.
