Processing and function:
The two ball heads 324RC2 and 327RC2 are very similar, both processed really good and adjust well, there is a belt that surrounds the handle with the key therein, which has the sense the clamping of the ball to decrease slightly in the transportation and under certain circumstances also in the use. The handle can be used for both right and left, you can rebuild the changing device with only two Allen screws so that the handle does not get in the way, depending on the camera and lens.
The load in the practice has good three kilos so far not exceeded with me, both at the 324RC2 and the 327RC2 clamps a Pentax DSLR with a 300mm / F4 and a converter firm enough in order to make long exposures without seeing sagging or anything else can be observed in the direction. With only one hand you have so the camera extremely fast geared towards the subject and if you let go of the handle that is really good fixed. With the above-mentioned belt you can use both models as ball head with friction, so at any time move the camera on the tripod without touching his head while having so much grip that you have stability in the photo.
The way I've used so far, the two models I level as a weatherproof, so far nothing rusts and everything works like the first day.
Positive I feel the size of the removable disk, which is very compact and interfere even not in my system camera to the housing boundaries. Another advantage is the fact that the removable disk automatically locks on the head, you should lever but after pressing in slightly in order to obtain final strength.
Benefits:
+ Quick and easy one-hand operation
+ Good workmanship
+ Good stability
+ Uncomplicated handling
+ Weatherproofing
+ Detailed description with exploded view
+ Quite small removable disk
+ Removable locks automatically
Disadvantages I in the almost three years out is not experienced with the 324RC2 in nature with the 327RC2 and the nearly two years. Both joysticks work perfectly so far and accurately. In my estimation, I would want to burden both models with a maximum of 3.5 kilos practical and is also sufficient for most applications. now I use the head not only in the blue hour but also in the "German wilderness" as a universal solution.
Now the restriction of the title comes - not suitable for every photographer - who wants to align with full load with one hand on the handle a large telephoto including body has to be clear that he provided his hand on the handle until the alignment is being which then means logically - he can not the camera Align two hands like a conventional spherical head and then tighten a lock.
Conclusion:
Who, like me, at exactly this system is used, thus aligning, release - finished - or such a system would have, which makes here garnix wrong with the two joysticks. Who is so often in the rain and / or mud on the road here as well has its pleasure in materiality. If you actually get time problems is an extensively illustrated instructions with which you quickly realize how to disassemble the entire head, which allows the cleaning and even a possible greasing with suitable grease (Nyogel is great for this)
Strong buy recommendation with full 5 stars - for both the 324RC2 and 327RC2 for - I would buy again and again if necessary.
