Definitely will add this lens to the family. It's going to add 56mm portrait quality with more working distance. Glad about the filter size so I can use the 5T diopter lens and get some close-up capability.

Miker, You basically need a transceiver or transmitter/receiver option that only uses a single center pin to fire the unit. Sometimes the units with multiple pins cause problems. The Fuji pin configuration on the shoe mount is supposedly similar to the Canon. Using the on camera flash that comes with the Fuji and the optical slaves on the SB-900 will work but you are limited by line of sight and distance. Pocket Wizards are also an option but they are expensive. This is all for manual flash which is the best option with the XT-1. Not a lot of versatile TTL available yet for Fuji. I am currently using 2 different systems with great success with Fuji XT-1. For speedlites I have Yongnuo YN-560 III's with the YN-560TX. This gives me control of power and zoom at camera position as well as radio triggering. The speedlites have built in receivers. My favorite setup is the the Cheetah Light CL-360 bare bulb flash distributed by CheetahStand. This is a bare-bulb light that uses Bowens mount light modifiers and is powered by a separate lithium power pack. It is basically a rebranded and modified Godox Wistro light. Also is controlled at camera position by a transmitter with a USB receiver in the the flash. This is a really mobile, versatile and powerful lighting setup. Edward Tang at CheetahStand is constantly adding options for his products and the customer service is outstanding. There is also a lithium battery powered speedlite, the V850, that uses the same remote system, so the lights can be used together. I use a Sekonic L-478DR meter and with this setup can get fast accurate exposures at my subject position.
