The Ideas for a Long Lens Support Bracket (Part 1), (Part 2), (Part 3), and especially the article A versatile Long Lens Support Bracket idea for push-pull zoom lenses (Part 4) were based on Hejnar Photo components.
As YLS-01 came later into the market, I thought it was just another iteration of a Yoke until I received a copy for evaluation and a closer inspection revealed its hidden design qualities that lack documentation and promotion in the web.
Packaging & Contents
|The YLS-01 comes in the usual by now shrink wrapped recycled-carton box branded with the Sunwayfoto logos. A large label shows the enclosed product photo, model number, main specification and ASIN barcode.|
|As usual all parts are nested in pre-cut foam sockets that protect them during transport, while an extra layer of foam bellow (thicker) and above (thinner on the lid) are there for even better protection from scratches.|
The Yoke / Bracket
|Total Thickness w/ wheels:||16 mm|
|Support Length*:||61 mm|
|Wheel Diameter:||30 mm|
|Mounting screw:||1/4"-16 UNC|
|Adjustment Height:||26-110 mm|
|The rear side of the YLS-01 is smoother with only a shallow groove near the middle captive slot. The rear side is slightly wider at 41 mm while the edges are convexed for a very good reason as we shall also see below.|
Sunwayfoto Design Innovation
|First innovative attribute is the hand driven mounting screw which has an entry threaded point in the captive slot at the bottom end of the slot. This means no tools required.|
Required Components for a Long Lens Support Bracket
As many times debated in past articles, a Long Lens Support Bracket, besides the Yoke needs a Long Multipurpose Rail with a front or rear tapped hole as minimum prerequisite and at best a dual subtend quick release clamp.
|Shown above are the Sunwayfoto YLS-01 Y-Type Long Lens Support, the Sunwayfoto DPG-2416 Multipurpose Rail which sports the required tapped hole on the rear side (considering the bubble level side to be the front) and a Desmond DBC-50 50mm Dual Subtend QR Clamp (Review) as readily available in my arsenal. Nonetheless, Sunwayfoto has also available the DDT-53 Subtend clamp and the DDB-53 Bidirectional clamp that would equally fulfill the task.|
On the other hand, although a little more complicated and more expensive the Dual Subtend or Bidirectional QR clamp can be exchanged with a Sunwayfoto DDH-03 Panning Clamp (Review) + DDY-58 Discal QR clamp (Review) combo. This solution will prove favorable for those who require the existence of both clamping orientations (i.e. Subtend = in line and Bidirectional = perpendicular to the main rail). Therefore, you can have both by turning the DDH-03 accordingly, that is to either accommodate for a Lens plate or a Camera bracket which is usually perpendicular.
Attaching the YLS-01...
Independent of the YLS-01 attachment method on the DPG-2614, the M3 Safety stop screw set below the rear 1/4"-20 tapped hole (at the side opposite to the bubble level), has to be removed in order to clear the mounting hole threads.
|This can easily be done using the appropriate 2.5 mm Allen hex key included with the DPG-2416 multipurpose rail.|
...Directly on the Multipurpose Rail
Obviously this is the simplest, easiest and cheapest solution as it takes advantage of the innovative design characteristics of the YLS-01 and requires no tools whatsoever.
|Just by screwing the YLS-01 into the rear hole of the DPG-2416 rail, it becomes clear how it matches and embraces the rail.|
|The YLS-01 is automatically aligned and can be adjusted up-down without any possibility of sliding / twisting on either side.|
...Via a Quick Release Clamp
Although direct attachment is quick, tool-less and perfectly aligned, there is always the possibility that the YLS-01 is used with a long multipurpose rail from another manufacturer, so its convex edges will not match the width or the radius of the rail edges.
In this case, the Arca-Swiss® compatible dovetail present on the YLS-01 may be used in order to align and adjust vertically the Yoke via a small quick release clamp.
|The Sunwayfoto DPG-2416 is shown above with a Desmond DAC-25 mini QR clamp that was handy. More details for the attachment of the QR clamp may be found in the Desmond DAC-25 Mini QR Clamp with Dovetail & Strap Bosses Review.|
Assembly of the LLS Bracket
After the attachment of the YLS-01 on the DPG-2416 rail, what remains is to mount the horizontal regulating clamp.

|The Sunwayfoto DDH-03 Panning Clamp combined with the matching Sunwafoto DDY-58 Discal clamp.|
Using the Long Lens Support Bracket
During a recent outing recorded in the article On Assignment at the Olive Groves I had the chance to use the Sunwayfoto Yoke for he first time on the field, combined with other Sunwayfoto Pano gear. Thus actually the idea of a horizontal regulator for the LLSB utilizing a panning clamp like the Sunwayfoto DDH-03 (Review) merged with its sibling the DDY-58 Discal clamp (Review). These came in handy as they are an integral part of the Pano-3 Multirow Panoramic head, playing the role of the vertical rotator.

|Finally Sunwayfoto LLSB with YLS-01 + DPG-2416 + DDY-58 + DDH-03 mounted on Sunwayfoto XB-44 low profile ball head on Triopo GX-1328 CF classic tripod and supporting a Gripped Canon EOS 7D with an EF 100-400 mm IS USM.|
Photos taken from the terrace of the small chapel of St. Nickolas (A Small Chapel in the Olive Groves) in distances ranging from 500 to 3000 meters away, may be a good proof of the extra stability given to the lens.

Sunwayfoto YLS-01 is an innovative Y-Type Long Lens Support sturdy enough to handle large and heavy lenses. It requires no tools when used with a matching rail to its curves.
It maintains the Sunwayfoto quality despite the recently reduced price which add en extra attribute making it an excellent value for money.
Note: The YLS-01 Long Lens Support Bracket presented in this article was kindly offered by Desmond Photographic Distribution, USA, for evaluation and review.
I hope you found the article and ideas useful, thank you for viewing.
