Hi folks,
one of my first posts here and I hope that you can help me understand if I need
to see an optician, or if maybe what I am seeing is really there...
Last three years I have been using K100D, am very happy with it and
quite recently I bought a K20D looking for more resolution and a camera
with better ergonomics.
Today I tried some test pics with FA* 200mm and I think I am seeing a
strange "sharpness pattern" that I am not able to understand.
Please have my apologies for yet another boring brick wall picture.
If you click on this
link you will see a full size out-of-camera JPEG
The picture is taken from a tripod (a sturdy one I would say) with SR disabled
and 2s timer with mirror lookup @ F8
Can you see some sort of "wavy" pattern when it comes to sharpness?
It should be noted that it is not taken through a window glass, and building
is far enough to exclude variations because of DOF.
If you do see it, do you have an explanation what could cause it?
In my view it can only be the sensor.
Have to say that I have not noticed any problems with same lens on K100D
but K20D is different animal alltogether...
Many thanks in advance for all advice,
Samir
