Nikon claims a 0.13 second start-up time and 50 millisecond shutter response for the D7000 and the shutter proved it quick by any standard Nikon Battery Charger. In the studio, we measured AF acquisition time as 0.15 seconds with shutter lag coming in at 0.01 seconds.
Single shot-to-shot times were as quick as you could shoot, reacquire focus and shoot again – about 0.43 seconds was my best time. Continuous shooting rates met the advertised 6 fps standard and in fact just a bit more, and the D7000 managed about 19 frames before the buffer took a break. You can set the camera to permit up to 100 captures as long as you keep the shutter button depressed, just don’t expect them all to be at 6 fps. Here are the middle 4 shots of a 6 shot sequence.
Anytime a company trots out a new system such as the 39 point AF system in the D7000 there’s perhaps a bit of apprehension as to how it will perform. After all, how would you feel if you plunked out some serious money on the latest model camera and found you’d gotten a faulty AF system? D7000 owners have nothing to fear based on my time with the camera. The Multi-CAM 4800DX system did a good job of acquiring focus in good to dim conditions and tracking moving subjects, particularly in the manual exposure modes. With a little customization you can select 11 or 39 AF points, and single-point, dynamic-area, 3D-tracking or auto-area AF. While the camera performed well tracking moving subjects in the auto and scene modes that first-time users may gravitate to, the D7000 Nikon Camera Charger will reward more experienced shooters with precise AF performance if they take the time to adjust settings to their shooting style and subjects. Here are some AF shots with a busy background, of zoo critters through glass and through glass in low light and a gull head on.
The D7000 built-in flash has a guide number of 39 at 100 ISO, which gives it a range of about 11 feet at the f/3.5 maximum aperture of the kit lens at wide angle, and about 7 feet at telephoto’s f/5.6 max aperture – minimum range is 2 feet. The flash will cover the field of view for a 16mm lens. The maximum recycle time that I encountered was about 3.5 seconds, and the camera can disable the shutter for a brief time if too many flashes in rapid succession pose a threat to damage the flash tube from overheating.
There is some barrel distortion at the wide end of the zoom and edges and corners are a bit soft, with some slight light falloff in the corners. At about 24mm the peripheral distortion is pretty much absent, and then the lens shifts over to pincushion distortion as it zooms beyond 24mm. Edges and corners are better at telephoto with only slight softening. The D7000 Nikon DSLR Camera Charger has an “auto distortion control” (off by default) that may be enabled to help reduce barrel and pincushion distortion during shooting. These shots at about 48mm with and without distortion control enabled show the effect.
