Well, the glowing reviews and praise for Sirui ballheads is justified, indeed.
I had come back to these forums after something of a hiatus, saw lots
of comments about them, and decided the time was right for me to
finally acquire some long-desired upgrades:
Left: K-20X on 725B, Right: K-30x on 055XPRO
The column of the 725 was replaced to facilitate the previous upgrade
to an Amvona head, allowing any other standard-mount head to also fit.
As mentioned in other threads, the K-30 is a great fit to the 055,
being a near-exact match to the column's shoulder diameter.
The 725's column shoulder is actually 4-5mm larger in diameter
than the 055's, which accounts for the difference seen in fit.
To anyone currently considering the Sirui gear: YES! Do it!
It represents tremendous value in an industry flooded with
frequently-overpriced equipment. Quality is right up there
on a level with the stuff that sells for triple the price,
as is operation and function. It probably won't take much more
time before the prices start going up to reflect how well they
hold up against the competition: that's how good these are
I'm now seriously considering a purchase of one of their CF
tripod legsets, based on their ballhead quality, before it'll
cost an organ donation to pay for.
