New Innovative Hejnar PHOTO Modular Lens Support Bracket Preview

Hejnar Photo MOD-6 LLSB on Support Rail

A new and very innovative modular lens support bracket was just released by Hejnar Photo under the model name MOD-6 LLSB. Actually the new LLSB is unique and original.

It is based on the reviewed Hejnar PHOTO Modular Lens Support Bracket MOD-1 with its 2" body rail but with a modified U shape lens supporting bar featuring 1.15" diameter wheels placed in a completely different manner than any other lens supporting Yoke or LLSB.

Up to now Lens Support Yoke wheels are placed perpendicular to the lens barrel in order to facilitate lens ring rotation. But what happens with long telephoto lenses which do not have an internal focusing system or long zoom lenses which extend when zoomed out?
Hejnar MOD-6 LLSB comes to fill this gap with its wheels rotating in parallel with the lens barrel length. This will allow for full support when a long lens extends / retracts while focusing or zooming.

The Support Bracket

Manufacturer Specification:
Model:LLSB MOD-6

As mentioned above, the MOD-6 design is modular and the Lens Support assembly incorporates the known Hejnar 2" support rail with double full-length Arca style dovetail on each side and a special U shaped wheel bar, which features the large size 1.15" diameter wheels.
The 2" rail has a captive slot and comes with an 1/4"-20 captive screw for direct mounting on a long rail like its sibling in the Hejnar PHOTO Modular Lens Support Bracket MOD-1 Review examples.

The U shaped wheel bar was obviously designed to hold the wheels angled and in parallel to the lens length. The M3 safety stop screw remains to forbid accidental bumping of the wheels, acting as a stopper on the long rail.

An application example illustrates a full Long Lens Support Bracket assembly, incorporating a long base rail with a QR clamp mounted on the front end, which in turn allows for vertical adjustment of the MOD-6 LLSB.
The camera is supported by a set of perpendicularly connected QR clamps that allow fore-aft movement of the camera body on the long base rail.
