New Lens: Nikon 35mm f/1.8 AF-S DX

A couple of weeks ago, I picked up a new lens: Nikon's recently-released 35mm f/1.8 AF-S DX. 

This lens has a fixed focal length of 35mm; if you have a lens like the D40's kit 18-55mm, it's like you dialed it to the 35 mark and locked it there.  On most film and pro DSLRs, photographers would get a 50mm "prime" lens: one that fairly accurately reflects the field of view that your eye would see.  Since the Nikon DX line of cameras has a sensor half the size of film, it takes a wider focusing lens to create the same effect - 35mm.

What makes it advantageous over the kit lens is the aperture: f/1.8.  It's a fast lens, meaning it can let in a lot of light in a short amount of time.  As I've previously mentioned, wider aperture will generally allow you to do one of two things:

  1. Shoot at a higher shutter speed for a given level of light.
  2. Create a shallower depth of field to isolate the subject.

This fills a hole left in the Nikon DX beginner (D40/D60) lens collection: We have the excellent 18-55mm for close-up and normal shooting, and the 55-200mm for things that are farther away, but nothing (well, nothing affordable that would autofocus) for taking low-light photos.  With this lens, as long as I'm willing to sneaker zoom (moving myself rather than the lens to get closer or farther away), I can get the shot in any reasonable light.

I've been playing with it while Jonathan and I are home in the evenings.  It's nice to not have to grab the flash when I'm taking pictures indoors.

BTW: check out the filenames on these.  My D40's "odometer" has rolled over past 10,000 shots.  Of course, I have significantly fewer than 10,000 photos to show for it: I know I burned through about 500 images of total blackness to get a couple of shots of lightning during a storm, and I've wasted snaps here and there shooting at the ceiling fan to learn about shutter speed or even just firing off some random shots to show off to Mom how Nikons "sound like real cameras".
