The X100, X-Pro1 and X-E1 are famous for their low-light, high-ISO capabilities, but sometimes a touch of flash can make an image pop where is could be flat otherwise. This is especially true in bright sunlight where harsh shadows and bright backgrounds can often lead to subjects not being properly exposed, or having harsh and ugly shadows across their faces. A fill-in flash can make all the difference. If used properly, flash can enhance a scene and allow you to use a lower ISO to get better image quality without the caught-in-the-headlights look so often associated with it. That’s another topic though, but I came to the realisation that with the correct use of flash I could enhance my images, so I started looking for the best way to add an external flash to my X-Series cameras. The X-Pro1 doesn’t have an on-board flash, so I initially bought the Fujifilm EF-20 flash as it was half the price of the X-Series EF-X20 version of what was seemingly basically the same flash in a different body! I didn’t see the point of buying the “X” version. I was happy enough with the EF-20, it worked well and was nice and compact for the X100 and X-Pro1, although it does hang a little far forwards....
Summary of the differences between the EF-20 and the EF-X20:
- Both flashes work in TTL with the X-Pro1, X-E1, X100, X100s, X20, X10 and X-S1 cameras and I believe they work with some of the Fujifilm bridge cameras as well.
- Both flashes have a Guide Number of 20, which is significantly more than the on-board flashes, though that reduces to 12 with the wide-angle option on the EF-X20.
- The EF-20 can tilt 90 degrees up to allow you to bounce flash whereas the EF-X20 is fixed facing forwards.
- The EF-X20 can operate as a slave, which means it can be used off camera wirelessly.
- The EF-X20 has +/-EV controls as a simple dial and full manual control down to 1/64th. The EF-20 is purely TTL.
- The EF-20 uses 2xAA batteries where the EF-X20 uses 2xAAA batteries.
- The EF-20 retails for around £80 where the EF-X20 retails around £170.
