FUJIFILM EF-X20 Reviews

Not Perfect but highly recommended

By John
Rated 5 out of 5

The good - reasonable output in a small size, well built. The great - single large control dial for compensation and/or power setting. The bad - long recycle time. 2 AA's just don't have the horsepower for fast recycle. A fair trade off. Wish it had a bounce but understandable given the form factor. Probably not the best choice if you only want one flash unit but incredibly useful for certain situations. Slave mode is a nice touch. Have used for years, will keep for years more. Best use daylight fill for casual shots, studio fill. Expensive but given the build quality you get what you pay for.

Pretty small and powerful, I use it on a Leica Q with Lightpix Labs wireless transmitter and the whole set up works great.

OK - I got this as a cheap - light weight filler. It works great for that. But i will be buying a full fledge flash soon.

Simple to use, works well in manual or TTL mode. Very basic but does its job really well, tiny so you won't really notice adding it to your bag permanently.

Always carry it with me

This flash is incredible. The only downside is you have to keep a ton of batteries in your bag (so much for the space savings) but it's worth it! The flash isn't in your face, clients love it, and it's really useful off camera with one of the canon TTL cords in hand or using a flash bracket. This is a must if you use anything else on top of your built in lens when using the x100 series cameras, since the on camera flash with cast a nasty shadow. Well worth it, have been loving it for years and years.

Sleek, but slow to charge and power hungry

The flash looks great on my X100V and exposures come out looking nice. However, the flash takes a pretty long time to charge up, and eats through the two AAA batteries extremely quickly.

question

Hello, how much voltage does the flash trigger in maximum? Will it be safe when mounted on an old digital camera such as Epson RD1? Thank you!
Asked by: Lanbiao Z.
Unfortunately, Fuji does not publish the trigger voltage for this flash nor has it been tested with any other cameras except those in the Fuji X series. Your results may vary when using it with a camera like the Epson RD1.

question

What wired remote shutter its recommended to fire this flash out of the camera shoe mount?
Asked by: Anonymous
There is no wired remote shutter for use with the Fujifilm EX-X20 Flash. You would either use the flash on the hot shoe of the Fujifilm X-series cameras, or you would use the flash in Slave Mode as indicated in the flash's instruction manual on page EN-4.

Asked by: Pavel
No, the FUJIFILM EF-X20 Flash does not have high speed sync. This flash will only perform high speed sync with Fujifilm leaf shutter cameras, such as Fuji X100f.
