Setting your camera up square on to the subject is not as easy as it sounds, it can be out in any plane and how do you measure it for accuracy?
Steve
camera the same distance off the sidewall and floor that the CL of the
chart is.
Postage stamps (Irish ones off ebay are quite detailed) make
good test targets.
The most important part is getting the focus right. Live
View is the best way, but it's more accurate to use a
focus rack and take shots say every 10mm on either side
of the LV focus. Alternatively put the target on a box
and move that. You can't rotate the focus ring on the
lens by the equivalent of 10mm.
Very few people testing lenses on the net actually get the
focus right and that makes the whole test useless
This (shot of a can which I use to check LV focus because
the dots on the side look like they move as you focus)
shows correct focus on the left and moved back by
only 7mm on the right, so even 7mm makes a big difference.
The shot is front focused.

90mm Macro lens at f/2.8 50% crop. You can see it
better at 100% but I've had to reduce the size to
800w to post here.
Distance 1050mm LED Daylight lighting.
The can isn't much use as a resolution test. I
use it just to test my focus.
Accurate focus of a single shot with just a camera and
lens is IMPOSSIBLE. You have to focus bracket.
DOF helps to make it look better and the luck/statistics
of getting say 1 in 4 right also helps.

bright framelines on the Q viewfinder which also works
well for anyone using glasses.

remove the front barrel. Remove a 6" length of black
electrical type tape which locks two lens element holders
together.... rotate the front one to infinity focus and
then tape up again.... very easlily done.

It is a Pentax only site after all and I'm sick of
arguing with people who have "Two Sheds"
My final post on the matter is this link to the 2012
Japanese Mirrorless camera sales which shows that the
Q sold almost double the number that the OM-D did last
year 5.8% to 3%.... So Pentax WIN..It's highly unlikely
that worldwide sales will be much different and Japanese
companies take a massive interest in how things sell on
their home market, often launching products only in
Japan to gauge if they will sell worldwide.

Good Luck to Pentax and the Q10+ models and lenses.

expired, probably thought they could sell it to Tamron....
happened to Microsoft once.... almost a customer spotted
it and paid the registration for them.

and Japanese Sales are published weekly so
they are up to date.
The camera industry have decided that both cameras
Q and OM-D go in the same group and coming 79th out
of 80 can't possibly be described as "getting it right"

As you say Algi, removal of the plastic has made no difference to the problem.
Has anyone had a Tamron Adaptall lens repaired or serviced anywhere lately?
or email the owner of http://www.adaptall-2.org/ he used
to hang around some of the MF forums.

church, you wouldn't think it was so big from just a shot
on it's own. The snow looks nice, but I hate the stuff
Nice dramatic lighting on the last one.

Olympus took out the OM-D, a digital up-date of the OM - film cameras.
Pentax took out the 'Q' then the K-01, what a waste of time.
Pentax should have spent money on a version of the LX, a digital version would have been 10 out of ten !!!
cameras sold in Japan for a few weeks now and the Q was
in the Top 10 for the month of Dec. It's currently scattered all over
the chart because of different packages. If they had less
packages it could well be in the Top 10. But 33, 35, 36 and
37 in the Top 40 isn't bad. 35 is actually the Q10.
It doesn't look like Olympus did get it right...
trying to con it's users into thinking it was the
equivalent of a FULL FRAME OM
Just how does a person eat their words?
Can we all come and watch?

points
The pentax_K5II_custom_image_bright_1353322715.jpg shot looks
to be focused on some leaves just in front of the camera on the
LHS.
The first near match further away looks better for the K5II
