Hello:
In contrast to other cameraplates Q-top MK edition is round. The camera plate interlocks at intervals of 30 degrees with the base. The plate can not twist against the basis. Because of the detents every 30 degrees the plate can be used as a panorama head / rotator - after the tripod and the Q-top MK edition basis have been aligned with the built in spirit level.
Camera plate and basis are of the same shape. Both are round and of identical diameter. With a little routine it will is no problem to attach the camera plate to the basis blind, without looking, only by groping.
Dismantling and connecting is done by a simultaneously pressing of the small safety button and the big interlock button. Both are placed, anatomical advantageous, on opposite sides of the only 44 mm measuring base. It is nearly impossible to separate camera plate and basis accidentaly. There are no levers for additional locking or combinations of handles to loosen necessary. The whole system is simple and safe.
The camera plate has a ribbing at its exterior due to which it can be srewed into the tripod socked of the camera or lens at ease and very fast - and without the use of any tools.
The plate has three o-ring seals inserted in the aluminium. The physical characteristics of this o-rings and their concentric arrangement allow a secure fastening at the camera without any clumsy counternuts or other anti turn mechanisms. Q-top MK edition makes a very effective, non slipping connection of camera plate and camera.
Camera plate and base will not entangle with or get caught in the camera bag, because of their low profile, the circular shape and the round off edges.
Q-top MK edition is precision machined from solid pieces of high strenh aluminium and stainless steel. The base is milled out of one single block of tearproof aircraft grade aluminium, not as other products assembled from a lot of single parts. The internal locking mechanism and the spring are beeing inserted with special tools into the aluminium block. The system is maintenance free.
In the bottom of the base are to adapter bushings 1/4" to 3/8" inserted.
Dimensions:
Diameter circa 44 mm (1 3/4"), maximum diameter circa 53 mm (2") over interlock button, height with camera plate circa 28 mm (1 1/10"), weight with camera plate circa 100 g (3 oz).

But how safe it is in use when a cam is mounted in portrait mode with heavy lens?
Any cam will turn down against the plate, if the plate does not have a locker pin.
Especially when the cam is mounted on left side of a panoheads vertical arm, when direction down looses the thread.

Hello Paul:
We have included the Q-top in our product range as a small rotator for
FishEye friends and as a "normal" quick release (horizontal mount).
Vertical mount / portrait position:
I personally prefer a slimmer vertical plate using our MK heads like
our MK PanoGiga e.g.the MA 323.
The Q-Top is very robust - I must try this out in vertical applications using a heavy telephoto lens.
The rubber rings must bear the weight without lowering the camera.
Best regards,
Marc
