RiceHigh's Pentax K100D Full Review
BTW, for the K10D units I tested, there was no major misalignment for the central point, but for the other red points, still there are obvious misalignment (mainly shifted to the left for both the rightest and the leftest point). Plus, there was a strange thing seen is that the leftest point is very dim to be visible, it could be seen only that I moved my eyes to the right when viewing thro the finder. Also, the red point illumination of K10D is obviously not as bright as the K100D (probably for the same LED projector component but the magnification is larger).
Nonetheless, for your case, you can first try to use a needle like object to try to move the position of the focusing screen by pushing its left or right sides depending on the misalignment direction (push in a counter direction). Do note you must do this carefullly and do never touch the surface of the focusing screen (which is plastic and is very easy to be scratched) and you must do this in a clean place to avoid getting dust into the inside of the camera.
My humble advice is do not return your K10D if AF accuracy and actual sensor sensitivity area alignment are okay. Just because it's likely that other K10D will have other misalignments for the red indication (since the design is not perfect, unlike Canon's red indication design, which projected to the craved marks). As it does not actually affect actual performance and is just an indication, you should be able to forget about it. But, it's annoying to see that, I know.
Anyway, if you still find it to be too annoying, try getting another one to see (if you have the luck!).
Honestly speaking, my luckiness record on this issue is as follows (for the central red point):-
1st *ist D: obvious shifted to the left
2nd *ist D (died after 4 month's use): no obvious problem
3rd *ist D: no obvious problem
1st *ist DS (killed by Pentax Japan during "repair"): no problem (perfect here)
2nd *ist DS (an on-loan unit during the above Japan trip): no problem
3rd *ist DS (a replacement unit by local agent because Pentax Japan destroyed the camera): obvious shifted upwards
Current K100D: Shifted to the left (as indicated in my K100D review).
Five other units of K100D checked at Tokyo in August last year: NONE of these are aligning good enough!(?) Two units inspected in HK in August (only one is okay)
Now that the simple maths come, for the non-defective rate on this issue for Pentax DSLRs is:
- Total sample size is 14 units
- Number of acceptable units: 5
- Good rate: 5/14 = 35.7% only!
- Defective rate: 9/14 =64.3%!!
So, you can judge if it is worthy to seek for a replacement! Anyway, good luck!!
Originally posted by Photomy Just received K10D a few days ago and noticed the red center AF indicator point is not properly centered in the central viewfinder bracket. Do we accept this as the norm? Is this common? Worth sending it back for a replacement?
Thanks for any feedback.
P.S. Just to clarify, I am referring only to the red, small, indicator box. The real focus point might be perfectly centered within the viewfinder. I have read that it is actually a cross in shape. It is hard for me to verify this. Did some testing by focusing on window pains, etc. but still could not really know for sure.
