It's a wide to mid-angle zoom, slightly faster than a kit lens. That's
all.

I've never seen one, But thanks for reminding me about it.

Sorry, I had kind of assumed that Tamron had by now updated their lens
with a focusing motor so it would work on the D40, D40X, D60 and D80
(and any other Nikon DSLR bodies I may have forgotten which lack the
screwdriver drive. Of course Tamron has already done this to other
key lenses in their range.

You may have a long wait. ;-)

Not on my D700, it isn't! ;-)

Yes, you have to crop it quite severely to get to 16:9.

Of course you have to crop Four Thirds even more severely, and there
isn't really enough image information to start with ....

How can you say that with a straight face? You must know that the trand is
towards wider, not higher, formats. Even TV sets and laptop computers no
longer use the 4:3 aspect ratio. The 1280x1024 flat-screen monitor is pretty
much the last non-wide holdout, and that may be mainly because its 5:4 aspect
ratio is moderately convenient when it's used in pairs.

And yet the Sigma lenses I own have performed very well. Is that because I'm
one of the few people smart enough to know which are the good ones? Or because
Sigma's QC problems have been greatly exaggerated by Sigma's competitors and
their fanboys?
