The good:

AF-S DX Zoom-Nikkor ED18-70mm F3.5-4.5G (IF)

Optics:

15 elements, 13 groups, one of which is an aspheric. This is not a cheapie "kit" lens (the 18-55mm is).

Diaphragm:
Seven-bladed rounded diaphragm, f/22 - 36 minimum aperture.

Size:

2.9" (73 mm) long by 3" (74 mm) long.

Weight:

14 oz (390 g).

Close focus:

15" or 0.38m, very good.

Filter Thread: 67 mm. I suggest permanently attaching a 67 -> 77 mm step-up ring and treating this lens as if it's got a 77 mm thread just like the rest of Nikon's pro lenses. This way you only need one size of caps and filters and other accessories. Trust me, you'll go insane if you buy different filters for every lens! No, you can't use the lens hood this way; I never use lens hoods so no problem. I just use my hand to block the light of the sun if it's shining directly into the lens, which works a lot better than the hood when you need it.

The SB-800 adds a reverse flash guide number mode for flash where you set the aperture and the flash sets the level automatically based on distance. This is like the flashmatic modes of the 1950s, backwards.

Power
The SB-800 has a rated GN of 125' at ISO 100 with the zoom head set to 35mm. At full manual power it has a recycle time of 6 seconds (alkaline) or 4 seconds (Ni-MH) and provides 130 shots (alkaline) or 150 shots (Ni-MH.)

Size:

2.8 x 5.0 x 3.6" (71 x 127 x 92mm), rated.

Weight:

12.3 oz. (350g), empty.
