Nikon D7500 Flash

 

Built-in Flash Test Results

Coverage, Exposure and Range
A fairly powerful pop-up flash with narrow coverage. Average exposure compensation required.

Coverage
16mm @ f/2.8

Coverage. Flash coverage was very narrow at wide angle (16mm or 24mm eq.), with dark corners and edges, although some of the light fall-off in the corners is from the lens itself. The 16-80mm f/2.8-4E can also cast a shadow depending on the distance and focal length, as you can see. We no longer test coverage at telephoto, as it's invariably much better.


Normal Flash,
f/4, 1/60s, +0.7 EV

Exposure. When it came to exposure, the D7500's built-in flash underexposed our Indoor Portrait subject slightly at its default setting, requiring +0.7 EV flash exposure compensation which is about the average required for this shot.


Manufacturer-Specified Flash Range

14 feet
f/4, ISO 200

Manufacturer Specified Flash Range. The Nikon D7500's flash is rated with a Guide Number of 12/39 (m/ft) at ISO 100 in both Auto TTL mode and in Manual flash mode. That works out to about 14 feet at f/4 and ISO 200. In Auto TTL mode, the flash produced a dim exposure, but in manual mode at full power as shown above, the Nikon D7500 produced a very bright flash exposure (almost a full stop overexposed), indicating the flash output rating is conservative.

Note: Here we shoot with manufacturer-specified camera settings, at the range the company claims for the camera, to assess the validity of the specific claims. The specified range has been calculated for the sensitivity, lens and aperture used in the test shot above.
