These clamps follow the innovative low weight design pattern established with the DDH-02 panning clamp.
Although they can be used with virtually any ball head due to their center hole and 3/8"-16 thread, Sunwayfoto's main intention is to complement their current lines of Panning clamps and Indexing rotators, offering an improved lower weight solution than the older DDY-64 Discal QR Clamp.
Sunwayfoto DDY-64i and DDY-64iL which was reviewed last November, are identical in all aspects except for the small detail of the longer Screw Knob shaft on the latter.
Meanwhile, I have received the DDY-64i Discal clamp as part of the Sunwayfoto Pano-3 Panoramic head package and since the characteristics of the clamp were extensively discussed in the DDY-64iL Discal Quick Release Clamp Review, the purpose of this article is to serve primarily as a reference by demonstrating the integration of the clamp into the Pano-3 panoramic head functions and secondarily as a comparison between the Sunwayfoto discal clamps.
Needless to mention, that the DDY-64i Discal QR clamp is available as a separate product.
The Package & Contents
When purchased as a separate unit the clamp comes shrink wrapped in the lately adopted by Sunwayfoto recycled-carton box, with a large white label on the top corner showing the product photo, model and main specification. In the box the DDY-64i Discal QR clamp and accompanying screws and tools are nested in a pre-cut foam piece that keeps them safely in place for transportation.
However, my copy arrived nested in the foam of the Pano-3 aluminium case but still was accompanied with all screws and tools (even the ones that are not necessary for its function in the Pano-3 package) in a zip-lock nylon bag.

Mounting on a Ball Head
A discal QR clamp may prove convenient for many applications. DDY-64i may easily be attached on the ball stem of a ball head either screwed via its 3/8"-16 hole or by utilizing the (included) M6 screw and the 4 mm Allen hex key.
For more information you may refer to the identical Sunwayfoto DDY-64iL Discal Quick Release Clamp Review.
Mounting on Sunwayfoto Indexing Rotator(s)
As with former DDY-64 and long shaft DDY-64iL, the perfect match for DDY-64i are the Sunwayfoto Panoramic Indexing Rotators. It offers them the extra versatility of quick mounting/dismounting Arca-Swiss® compatible plates or rails on their top platforms.
As mentioned previously, this clamp arrived in the Pano-3 package as a companion for the DDP-64M Panoramic Indexing Rotator. So, I will stay a little more on the details and illustrations of mounting the clamp on the specific rotator which will help as a reference for the Pano-3 head review later.
|Then the top rotating platform may be unlocked in order to position the clamp knob and the clamp opening at a convenient position so as all the Indexing Rotator knobs are fully accessible and operational.|
Mounting on Sunwayfoto Leveling Bases
Using the DDY-64 series of clamps on Sunwayfoto Indexing rotators is a common and proposed practice. However, DYH-66i leveling base is also equipped with the appropriate 1/4"-20 mounting holes. Therefore, much like its siblings DDY-64i will increase the versatility of the leveling base when fast action is a prerequisite.
|Once again using the two included 1/4"-20 short flat-head screws and the 4 mm Allen hex key the DDY-64i can be mounted on top of the Sunwayfoto DYH-66i Leveling Base making it more versatile in mounting and dismounting further equipment on its top.|
Sunwayfoto has a complete range of universal or dedicated camera and lens plates as well as a series of multi purpose rails which cover almost any need. Of course DDY-64i Discal quick release clamp is fully compatible with Sunwayfoto's own gear.
I have run the same tests and measurements on DDY-64i as on the identical DDY-64iL considering it more as a second copy. The numbers only proved the very precise CNC machining since the tolerances are at the range of 1/10th of a mm. !!!
For the readers that like numbers, I hereunder quote detailed measurements of the clamp Jaw dimensions, so as they can decide whether this clamp is compatible with the dimensions of their plates or rails.
|Clamp Jaw dimensions||mm|
|Steady Jaw Height||04.11|
|Moving Jaw Height||04.13|
|Min Jaw Lip Opening||33.94|
|Max Jaw Lip Opening||37.84|
|Min Base Opening||39.50|
|Max Base Opening||44.20|
The yellow figures in the above specs are considered a little lower than 5 mm which is the middle of the dovetail V cut. All other dimensions fall within the average limits, consisting the clamp compatible with a large number of Arca-Swiss® type plates and rails.
Excellent machining, finishing, fitting and build quality.
Very good scratch proof anodizing.
Very smooth operation in all aspects.
Very low weight for the size.
Excellent value for money ratio.
Clamp jaws are a little short for the dovetail edge radius of some 1/2" & 5/8" thick rails from other manufacturers.
With any excess weight eliminated, DDY-64i is another great example of design and CNC machining.
Its shape, size and particularly the low weight, make it a great option for many ball heads or monopods and an excellent companion for Sunwayfoto's own Indexing rotators and the smaller DYH-66i leveling base in order to facilitate mounting Arca-Swiss® compatible rails and / or plates.
The high standards of build quality for the price give an excellent value / money ratio.
The DDY-64i Discal Quick Release Clamp presented in this article was kindly offered by Desmond Photographic Distribution, USA, for evaluation and review as part of the Sunwayfoto Pano-3 panoramic head.
I hope you found the article and ideas useful, thank you for viewing.
