According to Hejnar PHOTO after the recent release of their Replacement Foot for Fuji XF 50-140mm f/2.8 R there was a quite strong pressure from Fuji users for an identical solution for the excellent and very popular FUJINON XF100-400mm f/4.5-5.6 R LM OIS WR.
Therefore, it was a matter of time for the Hejnar FUJI-100-400-FOOT to be released. This foot just came out last Saturday not only offering an Arca-Swiss® dovetail compatible solution but also added a larger footprint to the somehow tiny original.
Much like the FUJI-50-140-FOOT the new foot accords to the native Fujinon collar design with two knurled thumb screws which can easily detach and reattach the foot on the lens collar.

|Safety Stop Screws:||2 x M3|

The Hejnar Photo FUJI-100-400-FOOT is a two part design with an arched part which fits the Fujinon lens collar, featuring an alignment dowel pin and two stainless steel knurled thumb screws.
This collar arch is actually the difference between the two Hejnar solutions for FUJI lenses.
The lower part, which is shared by the two Hejnar models as proved by their dimensions, sports a double dovetail. The lower dovetail serves for the foot attachment on Arca style quick release clamps, beiing compatible with all designs of clamps even lever release clamps.
On the other hand the upper dovetail allows for the attachment of flash brackets and/or other devices equipped with an Arca style clamp.

Quite familiar for the readers that have viewed the Hejnar FUJI-50-140-FOOT article is the design of the base plate. The bottom side of the FUJI-100-400-FOOT is carved out with brace left to accommodate two tapped holes with 3/8"-16 and 1/4"-20 threads respectively, positioned front to back. These obviously serve for direct mount of the foot on any pod with a 3/8"-16 or 1/4"-20 stud.
Further, two M3 safety stop screws are factory installed, one at front and one at back end of the foot protecting the lens from falling off from a QR clamp not tightened properly.

Installation on the Lens
In order to replace the factory installed foot, it is very simple as it only involves unscrewing both thumb screws holding the original Fuji foot and removing it from the lens collar.
Then again, after aligning the replacement foot by its dowel pin with the respective hole on the lens collar, the user should carefully insert the knurled thumb screws provided with the replacement foot in their corresponding holes, just tighten them by hand and secure the Hejnar replacement foot onto the lens. No tools required.
As always and as a measure of precaution, it is advisable to use a drop of thread locking compound, like Loctite 242 (blue) or any other equivalent medium strength product, on each screw to avoid slack of the screw after time.

Although no tools are required for the installation of the replacement foot on the lens collar, the FUJI-100-400-FOOT is accompanied by an Allen hex key compatible with the factory-installed M3 safety stop crews.
According to Hejnar Photo the dovetail design and dimensions of the FUJI-100-400-FOOT conform fully to the Hejnar Photo standard, therefore compatible with Kirk®, R.R.S.®, Arca-Swiss®, and many other Quick Release clamps that have adopted the Arca-Swiss style.
