The SUNWAYFOTO Leveling Base Kit includes the DYH-90 Leveling Base and the DDY-64iL Discal Clamp.
Boasting a strong construction, the DYH-90 Leveling Base is designed for large format cameras. Featuring a platform with a diameter of 90mm, this base can be used with 4 x 5, 5 x 7, and 8 x 10 cameras.
The DDY-64iL Discal Clamp is high-precision CNC machined and uses a Metric 6 flat head screw to be mounted onto a ballhead. This clamp is compatible with all Arca-Swiss standard quick-release plates. This camera accessory can mount onto UNC 3/8" threaded posts as well.
DYH-90 Leveling Base
The Sunwayfoto DYH-90 Leveling Base features a 3.5" diameter base that supports very large loads up to 66 lb, making it appropriate for large-format still cameras and full-sized video cameras. The base tilts up to 17° in any direction and features a removable offset bubble level that tells you whether your shot hews to the horizon.
The DYH-90 has a 3/8"-16 screw at the top and 3/8"-16 thread at the bottom, for direct attachment to many tripods. Completely constructed of metal (including the control lever), the leveling base weighs just 1.17 lb.
Top stud and socket mount at bottom are both 3/8"-16
Anodized for a scratch-resistant finish
Removable offset spirit level
Discal Clamp 64mm With Long Handle
The Discal Clamp 64mm With Long Handle from Sunwayfoto is a Swiss-Arca-compatible integral screw-knob clamp with an anodized black finish. It has a captive knob, safety-stop grooves, and a hollowed-out design that reduces the weight of the clamp. It also has an extra-long handle, making it possible to mount it on the DYH-90 or DYH-90R leveling base. You can use an M6 screw to mount it to an AS-style ball head, and it will accept any standard Arca-Swiss quick-release plate. This Discal Clamp also has an integrated bubble level.
