Fujifilm X-T1 Flash

Coverage and Range
Good flash range, with slightly narrow coverage at wide angle. Our standard indoor portrait shot required average exposure compensation.

Coverage. Flash coverage is a little narrow and uneven at wide angle (18mm), leaving slightly dim corners and vertical edges in our flash coverage test image, though we've certainly seen a lot worse. Coverage is more uniform at full telephoto (55mm).

Exposure. Our Indoor Portrait test scene is was well exposed with +0.7 EV flash exposure compensation at ISO 200, which is about average for this shot. The camera's Slow-Sync flash mode produced a brighter image with no flash exposure compensation, though with a strong orange cast from the ambient room lighting.

ISO 200 Range. With the 18-55mm kit lens, flash exposures at wide angle are bright all the way out to 16 feet, however some exposures suffer from a slightly reddish cast and the shutter speed of 1/38s used was a bit on the slow side to avoid subject motion blur (the X-T1 seems to take current focal length into account when selecting a shutter speed). At full telephoto, flash exposures started out a bright at 6 feet, increased in brightness at 7 feet, then exposure started to fall but remained bright to about 10 feet.

Manufacturer Specified Flash Test. The Fuji X-T1's bundled EF-X8 flash is rated with a Guide Number of 8m at ISO 100 or 11m at ISO 200. That works out to a range of about 9 feet at f/4 using ISO 200. In the test shot above, the X-T1 performs as Fuji says it will, producing a well-exposed flash exposure at the rated distance with ISO set to 200.

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 a shot using the manufacturer-specified camera settings, at the range the company claims for the camera, to assess the validity of the specific claims.
