Yes, I guess that's one way to handle the "lopsidedness" of the
tripod mount location.  I suppose that one-touch zooms are often
going to have a problem with the rearward placement of the tripod
mount.  (But this one seems extreme...)

That is a good way to handle focusing, if you have the time.  My
problem is that I often want to be able to focus quickly - with a
one-touch zoom I am often focusing and zooming at the same time.

The width of the zoom range is indeed immense (and convenient for
framing).  And, I agree that the optical qualities are really quite
good.

I do, too.  However, I found myself using it at 600mm most of the
time (so that it almost ended up being a 600mm prime of sorts for me
anyway), and I have had better luck focusing with the A* 600/5.6 and
the Novoflex (follow focus) 600/8.  I have even seemed to have an
easier time focusing the VS1 600/8 Solid Cat, despite the speed
disadvantage compared to the (135-)600/6.7.

But the lens ~surely~ is built, isn't it? - <g>.
