Hi everyone,
I'm about to upgrade my ball head. I've spent last several days
reading numerous threads and reviews on various ball heads and
narrowed down my choice to 2 ballheads, namely Acratech V2 and RRS
BH-40. I'm currently using Gitzo G1228 and Manfrotto (Bogen) 488RC2
ball head. The heaviest equipment I use is F5 and 70-200mm +
TC-14E. I also shoot macro with 90mm. Current setup is mostly
adaqate, but I want to start using L-brackets and Arcaswiss-type
plates.
I've considered Markins M10 and Kirk BH-3 as well, but I have a
strong preference to low profile design, so I pretty much excluded
them from my choice unless V2 and BH-40 are inadaquate for my
needs, whic doesn't seem to be the case.
Quick operation is something I value very much and that's the
reason BH-40 with its lever clamp attaceted me in the first place.
Then you've settled the issue. You want "the fastest operation" and you say you have a 70-200mm f2.8. That totally rules out the RRS lever clamp, and mens you've got to get the Acratech.
The Acratech double threaded clamp has the fastest operation of any knob type Arca clamp, and it will accept virtually any manufacturer's Arca plates.
The RRS clamp head, while slightly faster than an knob type clamp in certain situations, deviates considerably from Arca's plate dimensions, so it will not work with some Kirk plates, or any Markins plates.
(Yes, it's RRS's problem, they blew it, or they wouldn't have to list Arca-Swiss as one of the plates that an RRS clamp will not work with. Since Arcs-Swiss obviously is Arca-Swiss compatible, RRS isn't).
You need to use Markins plates for "the fastest operation".
Neither. All you need is a simple Markins camera plate. Markins is the only company that I know of that makes high quality camera plates where the dovetails run fore and aft, the same orientation as on all lens plates (RRS, Kirk, Wimberly, and Markins), medium format plates, macro equipment, and the original Arca Swiss view cameras. The machining on the Markins plates are excellent, they're a leader in features (RRS has recently begun copying the hand strap slots Markins has been putting on their plates for years). Markins has plates specifically machined for a few popular DSLRs like D200, or "universal" plates for other DSLRs. I have universals for my D2X and D100, and a custom for my D200.
RRS and Kirk promote plates and L-brackets for 35mm and DSLRs that have the dovetail running "sideways" in relation to how it runs on a lens, a medium format camera, or a large format camera. I believe RRS was the company who originated the sideways dovetail on 35mm cameras, prompting the term "really rong stuff".
With the camera plate and the lens plate running in the same direction, you've got all sorts of tricks available. The tripod and mount become a "third hand" to help you change lenses, instead of something you fight with. Say you're shooting your 70-200mm, and you decide that the scene needs the "magic" of the 85mm f1.4. Grab the big zoom firmly with one hand, release the Arca clamp with the other, and slide the 70-200mm out of the clamp, and the camera's plate into the Arca clamp, will holding everything by the lens. Lock the arca clamp, hit the lens release button on the camera, and dismount the lens. You've never changed your grip on the lens, and there's the camera, level, pointed in the right direction, all ready for you to twist and lock the 85mm f1.4. Takes about 15 seconds for the whole changeover.
Try that with the camera bracket sideways, and you add a dismount the lens, walk around the tripod to where you can slide the camera into the clamp sideways, walk around again to dismount the lens, then reposition everything to set up the shot again.
Before I discovered Markins plates, I used to use plates meant for lenses on the camera, so the plate runs fore and aft, just like a lens plate, and a square plate with grooves on all four sides on the bellows). The Markins plates are even more convenient. Most have "bidirectional" dovetails. The dovetail portion of the plate is 36mm square, the dovetail being machined on all four sides of the plate. This means you can use the plate with that fore-aft trick I mentioned for changing lenses, or also use them with equipment like the Novoflex Castle-Q or RRS macro rails that require a sideways lens plate. Don't worry that the Markins playe only gives you 36mm (about an inch and a half) of dovetail, vs 50-60mm (2 inches) for a "really rong" sideways plate. You don't realize just how strong 36mm of milled aluminum tongue and groove plate mated into an Arca clamp is. It's sturdy enough to tear the camera to pieces before you'd twist the plate loose. Engaging 2-3 inches of sideways plate is overkill, for no good benefit, at all.
