Both Clamps retain the size and the lightweight characteristics of their predecessors, (which were fully previewed and reviewed in the past) with some changes that promise to improve functionality and durability.
These changes lead to some visible alterations in the design of the Panning Clamps as well as a hidden but substantial one.
Most prominent literally, is the new screw knob with elongated shaft adopted on both clamps. The original models in favor of compactness sported a very short, actually nonexistent, screw knob shaft which has proven dysfunctional when hidden bellow very wide camera plates or larger camera bodies so it had to change. The new screw knob is made out of one piece aluminium and has thinner groves than the older.
The next obvious change, is the top surface of the clamps which now is more flat giving a better support and combined with the sloped edges allows the unobtrusive slide in of plates and rails.
However, the hidden attribute of the Improved DDH-02i and DDH-03i clamps is the complete redesign of the moving jaw mechanism. Aiming for stronger clamping and better stability the flat tongues that guided the moving jaw of the clamp, have been replaced by two stainless steel bars that we can see exposed in the photo above.
I will only be able to comment on the effectiveness of this change after a hands on test, though.
Nevertheless, these changes had a minimal effect on the weight of the clamps as we shall see further.
The DDH-02i Clamp
Model DDH-02i Panning Clamp....
Top Base Diameter: 52 mm
Pan Base Diameter: 51 mm
Height: 16,75 mm
Weight: 78.6 gr
Max Load: 18kg
Bottom thread: 3/8"-16 UNC
Apart from the forementioned changes /improvements DDH-02i Panning Clamp has now a more functional panning scale ranging from 0° to 360° instead of the controversial 0° - 90° - 0° - 90° found on its predecessor and common to ball head panning bases. Otherwise, just for the record, the height was reduced by 0.15 mm and the weight increased by 8.6 gr.
The DDH-03i Clamp
Model DDH-03i Panning Clamp....
Top Base Diameter: 58 mm
Pan Base Diameter: 57 mm
Height: 21.6 mm
Weight: 121 gr
Max Load: 20 kg
Bottom thread: 3/8"-16 UNC
Bottom Plate: AM-02 (57 mm)
In regard of the DDH-03i clamp there are not any other worth mentioning changes, but a little decrease of the weight by 5 gr.
|Otherwise, it still carries the removable AM-02 Arca Mount plate at the bottom which can be mounted in two positions.|
I hope you found this article useful, thank you for viewing.
