Are the focussing problems occuring using all AF sensor points, or does
it also happens if only one is used, for instance the central one?

In the end, I concentrated my tests on the central sensor, but the outer

It is stated, that the AF is not correct for lenses like the FA 1.4/50,
FA*1.4/85,
The problems noted on dpreview actually relate to focus accuracy with distant objects,
near infinity. Problems are said to be much more significant there than at closer
distances.
I used to be so bad at focusssing manually though, that any innacuracy would still be
far better than my

My conclusion is: focusing problems with *istD are exaggerated, it is rather
difficult to obtain better results during action manually focusing at
shallow DOF, and if you want top focus on stationery object, than you have
time to use MF anyway. Enjoy your cameras, taking all these great

you're drawing your conclusion based on your sample only.
To me, it's an obvious quality-control problem.
So please don't tell us, focusing problems with *istD are exaggerated
Hi!
Bill, I think that what we're seeing know is what called among my kind
- the bleeding edge. This is very first generation of Pentax __new__
AF system. I am fairly sure that what people are observing can be
fixed in the program, not in hardware...
I hope though that this is nothing more

William,
normally I'd say 100% ACK but the viewfinder of current DSLRs is like
a view through a tunnel.
Especially when you're changing back

Agreed about that. Unfortunately, this seems to be the way of the world. Of
all the APS sensor sized DSLR's I have seen, the ist D seems to have the
best one, but for sure, the LX is better.
It is the downside of having a smaller sensor. Light is being
Hi Thomas,
I am very much looking forward for your report whether and how Pentax
will be able to fix the AF accuracy of your *ist D!

This is the problem I reoprted months ago regarding the Canon dslr units.
A local pro with 3 found that all of them focus differently.
If Pentax is consistent in its error then that's better
than the competition, though not what it should be.
My suspicion would lean more toward design,

I know the MZ-5n does not feature SAFOX VIII, but this is my usual
setting. However, I seem to recall that one one occasion this turned
out to focus more slowly than the other one.

on the 135 the autofocus is so fast i barely even notice it happening.

I was alerted to them when I got back in touch with the guy
who sold me my 80-200/2.8; he claims he has demonstrated the

There are some ongoing threads on DPReview about the issue. The last
