Re: Manfrotto quick-release plates and slippage when orienting the camera
and lens for portrait format shots -
John Shaw, on page 72 of his book "Close-ups in Nature" illustrates a
simple aluminium ledge he made to screw on to the hexagonal QR plates.
It would work a treat, and I really *must* make one before I stuff-up the cork
mating face of the QR plate through me having to tighten extremely hard to
overcome slippage. The tightening method I use involves using the camera
and lens as a wrench ... :-(.
I wouldn't be without my QR plates, even if new ones do cost $60+ each.
They make it SO easy to swap cameras on one tripod setting, and at other
times ...
The only other significant grouch I have about the hexagonal plates ( other
than the slippage issue) is that (although the hexagonal plate intuitively
would seem to be a great format) in practice they can be deceivingly
treacherous; several times I have thought I had the camera securely locked
on to the top of the tripod, only to have it fall off. I now routinely give the
secured camera a bit of a yank to check that it is indeed secure.
The limited experience I have with the rectangular QR plates is that they are
much more certain of getting a secure anchorage at first try (so that a
second try is not needed).
If anybody would like a picture or two of the Shaw plate, please ask and I will
provide.
Brian Swale.
