New Improved DDC Series QR Clamps from Sunwayfoto

Sunwayfoto DDC-37 QR Clamp w/ extra bubble level & hex key
At the verge of the 2012 year end, despite all the catastrophic scenarios and omens Sunwayfoto has released a new Quick Release clamp and has updated/improved three of the existing QR clamps of the DDC series.

The updated DDC series is sporting five different models ranging from 26 - 60 mm length covering a large range of needs.


Nevertheless, DDC series has more but specialized models as the DDC-G1 for the Gitzo traveler ball head and DDC-60X originating from XB-52 ball head.

Conclusion
DDC-37 originating from the FB-28 ball head is the new entry following the latest Sunwayfoto design standards. While the "i" on DDC-42i, DDC-50i and DDC-60i signifies major improvements implemented, regarding substantial weight decrease and functionality enhancement with the addition of extra bubble level mounting holes and detailed decimal scales.
Sunwayfoto designers and engineers seem to utilize the power of CAD and CNC machining precision in an endless race against volume and weight. On the other hand, as proved by some of my recent tests they still maintain strength and durability. All that at very logical and affordable prices. Well done gentlemen!
