I became the proud owner of a Pentax K10d in Janurary, my first DIGITALL SLR. Being experienced in regular SLRs but totally new to digital photography I just can't tell which "quirks" are due to the camera and which are due to my inexperience (or even to "unrealistic" expectations)
That being said, I would like to know if there is a good and standard way to TEST for back/front focusing problems. Tho I am sure experience will tell, I would like to be certain while I still have the chance to get it taken care of under the Pentax warranty.
I have heard that some of the earlier K10d revisions had back focusing problems; checking the revision # on my camera I found it to be 2.1 ( which is newer than rev.1.1 which was reported to have the backfocus problem, but much older than the current revision 8.1)
NOTE: If I do have any focusing issues, they don't seem obvious (or at least obvious to me), and I admit the way I've been testing the camera is often worse case scenario: aperture fully open, or close to it..sometimes,but not often, and trying to focus on a specific detail.. Such as a lose thread of yarn, a wick, the beak of a mounted bird, etc.
Again, I really haven't had any obvious misfocusings, but sometimes when I try to "test the envelope" as mentioned above I just cant measure the results consistently. If I am focusing on a candle wick that's a couple inches in front of a birthday card (or other high contrast object) and I hear the "beep" an see the focus indicator light up... I take the picture and sometimes I get the WICK in perfect focus sometimes it's the card...again.. Am working with a very small DOF here ON PURPOSE.
As always, thanks advance for sharing your Pentax wisdom
