Bonjour,
I was surprised to realise that some of my pictures hadn't a truly horizontal horizon, despite being very careful at holding the camera and using the AF frame on the viewfinder
.
After checking on numerous forums, I went to Pentax this afternoon, and let my K10D to be repaired. After a quick review, the after-sales technician said the focusing screen on the viewfinder may have moved a little. Fixing it would take two weeks.
That means two weeks without taking picture
[EDIT: Test protocol added] So I decided to investigate: here is what I've found so far.
Many forums talk about the problem dpreview Pentax User - Pentax Camera Magazine aficionados K10D (in French) K10D forums (in French) Here's my test
The K10D and an object (here, a level-meter) are placed on a table, at 120 cm. Both are centered.
The picture taken by the K10D is perfectly right and horizontal. I used the remote + 3 seconds, and the shake-reduction system is off.
However, the viewfinder shows something different: the image is twisted. That means that, if I rely on the viewfinder to check my picture is horizontal, I may have a twisted picture.
I performed the same test with a DA 18-55mm at 35mm and 55mm, and with a DA* 50-135mm at 50mm. Same results
.
So I plan to send my K10D to be repaired !
Are you experiencing something similar with your K10D ?
Best regards,
