Simple plate will do the trick. You of course will need a clamp if you are seriously thinking about switching to the best system available. Plate and plate/clamp combinations are available in my store .

Lens plate selection

As you all know, I am not a fan of dedicated plates (I do change my lenses and camera every few years and I hate when a perfectly good camera or lens plate can not be used with newer equipment simply because the hole location changed just a bit).

I do receive a few questions every week about what plate should be used  for XXX lens.  In some occasions, the answer is simple. But sometimes it is not. To determine type, length and plate type please follow these short guidelines

1)Determine the number of screws you need. If your lens foot has more than one mounting hole, it is recommended that more than one hole be used to mount the plate in order to keep the plate from twisting on the foot. If your lens foot has only one mounting hole, see the anti-twist section below.

2) If your lens has only one hole, you can prevent the plate from twisting on the lens foot by positioning the plate ridge on the back of the plate, against the back of the lens foot If you need or prefer to have the plate extended behind the lens foot, you can set the plate ridge against the front of the foot. You also have the option of purchasing the plate with a removable ridge. In that case the ridge can be mounted in various positions along the plate.

3)To determine the length of the plate needed for your lens please measure your lens foot. In normal circumstances that is length of the plate you will need. If you are using optional flash brackets and you wish to mount it on the lens plate you may prefer to add an additional 3/4 of the inch to lens plate. Also you may opt for one that is a bit longer than your original lens foot, especially if you are using a gimbal head where you have to move the camera and lens backwards and forwards to get optimal balance.

4)If your lens foot has a 3/8" mounting hole (very rare) install a reducer bushing into this larger mounting hole. This allows use of the 1/4" plate fastener in the larger 3/8" hole. You can purchase reducer bushings in the miscellaneous section if you have a 3/8" hole, the center slot is not wide enough to use 3/8" screw.

New clamps

Few addition to my clamps

Table top clamp(F60) - 1.00 inch wide  with center hole as always countersunk for 1/4-20 and M6 screws but also threaded 3/8-16. It works great with small point and shoot camera with combination of arca swiss type clamps. 


Second addition is 2.375 inch clamp with bubble level. (F72)
This clamp was long overdue since i had tons of request for a clamp with built in bubble level.



Since I had to removed  side holes from this model to have room for the level I also found room on the opposite side for a dowel pin locator. Now two of them can be connected back to back  in various orientation to each other by using pins and bushing.


Also 4 inch clamps are back in stock as always with short and long knob options.


And since I had request from Germany to build 122mm (4.8 inch) clamp same of them are also available. Please not that they do have 3/8-16 taped holes spaced 35mm apart. 




Also i do have all clamps available with black knobs
