It'd better be.

Dpreview, while impressed (for a CDAF), doesn't think the AF
"would shame most of today's DSLRs" ... I read there that
they'd prefer a DSLR for fast action.

I'd like to see tests in bad conditions (low light, low contrast,
both, etc.) with reliable numbers for from misfocussed to shot
time.

There are also systematic errors in sensor mountings, lens mounts
and lenses --- guess how many lenses are actually 100% parallel
to the sensor. Most PDAFs function very well, thank you.

I love mine too, and the FZ100 even more so.

Neither is nearly the equal of a DSLR, but when you need a superzoom and can
live with lower ISOs and the usual EVF shortcomings, these little Panasonics
are great.

Why not using a manually focussed camera instead --- that way
you get a real, reactive, well-tuned focussing ring as well.

In other you can post by pressing the necessary buttons
with your nose, if your hands are unable to move. (I still prefer
using fingers and a good AF)

How many professional wildlife shooters are superzoom users?
How many use DSLRs? Smile

What, CDAF being OOF? How comes? After all, superzooms and
P&S use CDAF too ...

Since they have everything in focus all the time anyway. Smile

Show me the P&S that focusses accurately and fast at LV 3 and
produces mostly clean, printable images (20x30cm or larger)
at effective ISO 6400-12800, can work with multiple off-camera
flashes (which are to be remote controlled in power, if possible
with a flash automatic too), produces a shallow DOF if asked
(like, say, a 50mm f/2 or faster on a crop-DSLR), shoots RAW,
and has a f/2.8 or faster lens (if not, you need to up the ISO
above by the necessary amount). Smile
