Nikkor 20mm F/2.8 AF-D
Filter Size: 62mm
This lens has been a true workhorse for me. On the
format the 20mm becomes about 28mm, my personal favorite focal length
general shooting and kayaking. I think this is the lens that made 28mm
my preferred focal length. I bought it to go on my D200, wanting the
small size and extra 2/3 stop of light over the 18-55 or 18-200. For
shooting sports the D200, with a base ISO of 100, really needs every
bit of light it can get. Nikon has several F/2.8 zooms that cover this
range, but they are all massive, heavy, and expensive. They are
anywhere from 22oz to 35oz too! The zooms sit comfortably in the $1,500
range, and unfortunately the 20mm 2.8 isn't all that cheap either,
retailing around $550 new and $300-$400 used.
Due to a fairly large diameter the lens appears
than it is. In real life its short length makes it small and compact,
especially when mounted on camera. Not renown for it's performance on
digital bodies, the 20mm isn't disappointing either. All round it's
sharper with better color and contrast than a 18xx kit zoom, especially
in low light. The AF is fast enough to keep up with action shots too.

Not bad wide open either, this has been run as a cover.

change to FX I expected to like this lens even
more. That was not the case for me. While the lens held up in the
center optically, I
found I didn't really like the 20mm field of view. Corners and edges
really don't hold up on FX.
For my taste, it's
just too wide on
FX for whitewater except in special, rare circumstances where
it's possible to get within a few feet of the kayaker.
