Was researching gimbal heads and being on a budget I was leaning towards the gh2. I primarily use a D500 with 200-500. Tried doing a search for a topic on this head,but didn't see much. Any input on the GH2 would be great.
There's nothing at all
wrong with the Benro GH2... it's identical in design to dozens of other J-post, bottom mounting gimbals and would work fine with that 200-500mm lens.
What you need to consider is that...
1. It makes any tripod you install it on "long lens only", unless you are willing to carry another head and swap it out. Any "full size" gimbal such as this fully replaces the existing head on the tripod and... without additional accessories or a head swap... prevents using the tripod with other gear, such as mounting the camera directly when fitted with lenses that don't have a tripod mounting collar.
2. It ain't small, isn't light weight and is fairly pricey. At $356 the Benro isn't the most expensive. For example the Wimberley WH-200, the original version of which started the whole gimbal thing 20+ years ago, is more than $200 more expensive. And there others that are even more expensive (RRS, ProMedia, Zenelli and others). At about 3 lb., the Benro is about the same weight as most full size gimbals. The Nest, when it was available (it's not presently AFAIK, in spite of the "live" web page linked earlier), is a bit more affordable, uses superior carbon fiber materials for a bit of weight savings and to better absorb some fine vibration.
At the other extreme are cheap Chinese knockoffs that cost $100 or less.
Here's the rub... They all do pretty much the same thing. I have little doubt the Benro, Nest, Wimberley, RRS, etc. are better made, smoother operating and will hold up longer than the cheap Chinese knock-offs (Meike, Movo, Smith-Victor and a bazillion other names, though all are probably made in the same factory). But, even the <$100 ones work... at least for a while.
3. There are alternatives people often overlook. Twenty years ago I looked at the Wimberley full size gimbal head, but really didn't want to have to carry two different tripods.... one for long lenses and another fitted with a more traditional head for everything else.... Or have to swap out heads in the field. Fortunately, Wimberley also offers their SK-100 "Sidekick" gimbal
adapter, which works in conjunction with any moderately heavy duty ballhead that has an Arca-compatible QR platform, to provide the same gimbal function. It not only leaves the standard head on the tripod... simply remove the adapter to convert the tripod back to "regular" use. It also weighs less (under 1 lb... but when used with a heavy duty ballhead, probably about the same 3 lb. total weight).
There are now a number of copies of the Sidekick, too. The Induro GHBA and Movo GH400 are almost identical clones. I can't speak to the quality and long-term durability of the others, but I've been using the Sidekick for twenty years (with a Kirk BH-1 ballhead) and it's still working fine. The Jobu BWG Mini is a less expensive, smaller and lighter adapter (fine for 70-200s and maybe small 300mm... but insufficient for a lens the size, weight and focal length of the Nikkor 200-500mm).
Wimberley used to advise using the Sidekick with lenses up to 500mm f/4 (8 lb. in those days), which was the heftiest lens I regularly use. But a number of times I've seen folks using them with bigger and heavier 400mm f/2.8 and 600mm f/4. I've even used it a few times with a huge, vintage 800mm lens that weighs over 10 lb. (a collectable, not a "daily user").
There are also "U-post" style gimbals.... but those are intended for particularly heavy gear. Way more than you or I need.
Here is a photographer's website where he has compiled a fairly good list of the gimbal heads and illustrates the different types:
http://www.carolinawildphoto.com/gimbal_list.htm4. Notice that some full size J-type and all U-post gimbal heads are "bottom mount". The lens mounting platform is horizontal. Gimbal adapters and some J-post style are "side mount" with a vertical lens mounting platform. The vertically oriented type typically have somewhat lower weight carrying capacity, though most are more than sufficient for a 5 lb. Nikkor 200-500.
Another use I've found for my Sidekick with it's vertical mounting platform is that I don't need any bulky, expensive L-plates on my cameras. If I want to mount a camera vertically above the ballhead, I simply use the Sidekick. It works fine for that purpose, as I'm sure most gimbals with vertical mounting plate would (Note: There are some J-type that are convertible, can be set up either bottom/horiz. mount or side/vert. mount, although additional, separately sold accessories may be necessary.)
Incidentally, Movo has a good discussion of the different types of gimbal heads that you might find useful, whether you buy one of their products or not:
https://www.movophoto.com/blogs/movo-photo-blog/gimbal-head-comparisonFinally, to use it on any gimbal, you will need to set up your Nikkor 200-500mm with some sort of Arca-compatible mounting plate. This is necessary to be able to attach the lens, but also allows some forward/backward movement to balance the lens on the gimbal, making it smoother and easier to move with a light touch. There are several possibilities:
1. A long lens plate (with anti-twist feature):
