Jobu Design introduces it's new lensplate lineup for 2009.
Our new Surefoot NX Series plates offer all of the same benefits as the previous style of plates, including double-safety-stops, double-dovetail profile (offering ease of use for quick release flash brackets), and compatibility with all other North American 'Arca-Swiss' style lensplates***.

Fitting Guide:
In general, select a plate that is 1" longer than the mounting-foot on your lens. This allows enough room for a flash bracket with quick release to be added.
Most small lenses use 1 mounting screw. Select an NX1 or NX2 plate that has a built in anti-twist flange to prevent your lens from unscrewing during use.
Most medium-large lenses use 2 or more mounting screws. Select an NX3 or NX4 plate for these longer mounts. These plates include two (2) 1/4"-20 screws and one (1) 3/8"-16 screw. No anti-twist flanges are required.
For odd lenses, or specialty purposes, or as a secondary "do-all" plate, select our NXM plate which offers multiple positions for mounting your lens. This plate comes with (2) 1/4"-20 screws and an adapter bushing included (3/8"-1/4"). Virtually all lenses with a mounting foot under 5" can fit this plate.
All plates come with appropriate allen keys for fitting. You may wonder why we do not use small slotted screws so you can tighten your lens with a dime instead of including so many keys; in general, tightening any small screw with a dime does not offer enough torque and you will repeatedly find your kit getting loose. The allen keys supplied will apply sufficient torque so that your lenses should never fall off due to the screws backing out. Of course, check for tightness periodically (especially after travel (vibration), or many temperature changes, which may affect the screw tightness).
We will send you replacement allen keys at no cost should you misplace them if you have a valid proof of purchase of our Jobu Design products.
*** Internal measurements have shown that some brands of plates that claim to be 'Arca-Swiss' compatible are too small due to use of Metric stock aluminum sizes. We have tested many brands and the North American plates seem to have a common size and can be interchanged freely; however offshore brands such as Markins and the original Arca-Swiss, plus other cheap E-bay lenses are too thin and the V-groove is too low. Use caution when buying unknown brands.
*** Use caution when using FLIP-OPEN Cam-type quick releases from other manufacturers. Although we strive to match the 'standard' Arca-Swiss size, we cannot guarantee 100% compatibilty with these specific types of clamps due to the other manufacturer's tolerances.
