Nikon D5200 Flash
Flash Test Results
Coverage and Range
Decent flash range but narrow coverage at wide angle. Our standard shots required an average amount of exposure compensation.
Coverage and Exposure. Flash coverage was rather uneven at wide angle (18mm), with very dark corners. Coverage at telephoto (55mm) was much better, but still somewhat uneven. (Some of the corner shading is due to the lens itself, though.) For our Indoor Portrait scene test, the Nikon D5200's flash required +0.7 EV exposure compensation adjustment to get bright results in normal Auto flash mode with a 1/60 second shutter speed, which is about average for the DSLRs we've tested. The camera's Slow-Sync flash mode at 1/13 second produced bright results without any compensation, though with a stronger pinkish-orange cast from the room lighting.
ISO 200 Range. With the kit lens at wide angle, the Nikon D5200's flash exposures started out bright at 6 feet, and brightness remained good out to 13 feet before dropping off rapidly. At the telephoto end, flash intensity started out a bit dim at 6 feet but got stronger at 8 feet, then dropped off from there. We'll call the range 8 feet at full telephoto.
|Manufacturer-Specified Flash Range|
Manufacturer Specified Flash Test. The Nikon D5200's flash guide number is 12 meters in Auto mode at ISO 100. That translates to about 11.2 feet at f/3.5 and about 7 feet at f/5.6, the maximum apertures of the kit lens at full wide angle and telephoto respectively. In the shots above, the D5200 appears to underperform by a small amount relative to Nikon's specification, producing slightly dim exposures at the rated distances. The flash target was underexposed compared to the ideal exposure by less than 1/4 f-stop at wide angle, and about 1/3 f-stop at telephoto. Our standard test method for flash range uses a fixed setting of ISO 200, to provide a fair basis of comparison between cameras. We've now also begun shooting two shots using the manufacturer-specified camera settings, at the range the company claims for the camera, to assess the validity of the specific claims.
