manual focus problems on k10d
Depth of field will render some sharpness to either side of the plane focused on and is generally well understood. There is also some leeway in a similar way at the point the lens focuses the image on - the point where the film or CCD would be optimally placed. This is depth of focus. The mirr...

manual focus problems on k10d
but might use f8 to ensure the whole face is in focus. Maybe under studio flash we would use f11 or f16. DOF will cover most things in this case. This is precisely why I don't think the sharpness of normal shots is at all a good measure of whether the camera is working right. DOF would mask focus...

manual focus problems on k10d
I saw this a long time ago (http://www.leongoodman.com/d70focus.html), and although it refers to the Nikion D70, the same 'cams' can be seen in the K10D (and the *ist series beforehand - probably just about any SLR). Presumably these cams can be incorrectly set and the focus would then be 'off', al...

manual focus problems on k10d
He, he, followed the directions for assessing where the focus points are located. Simple enough. it seems my focusing is a tad bit off center, as I have seen in th past. This may also be why I assumed my focus was off (faulty assumptions that focus was in the center, and extremely narrow DOF). ...

manual focus problems on k10d
I suppose I could have this repaired, but now that I know exactly where the sensors are I can compensate for that. I'm amazed. I would go mad trying to put up with that.

Yeah maybe, but would you rather go eight weeks without the camera? Last repair took that long. I won't do that until it is totally unusable!! So for now I will live with it. Argh! :evil:

customer service and stuff... Thought: does being a member of Pentax User count for anything in terms of service?

But the guarantee will run out. Yeah, you're right. I bought the three year warranty. I had the same thing with my istD. It soft focused and I waited until I had the K10D in my hands (and 14 days before the end of the warranty) to have the istD serviced. It came back with such a nice sharp im...

he, he... dunno if I can get that past the wife. But I suppose for the price of the DA* lenses, the extra body won't even be noticed. :twisted: :idea: Now, just have to figure out exactly where can I sell that second kidney?

Just got the test chart as I've noticed some back focusing problems with my DA 50-200 and A50.

manual focus problems on k10d
Well, all my other lenses seem to focus correctly and the camera locks perfectly. My 50-200 seems to back focus a fair bit. Secondly, it is supposed to keep in focus thought the zoom range. Mine changes focus quite a lot as I zoom which indicates there is something wrong with the lens. It is supp...

manual focus problems on k10d
I'm not sure how accurate the design of the 50-200mm is, but lenses that should keep their focus don't always, and I would imagine the wider the zoom range the less likely focus is to hold. A zoom technically means focus is kept spot-on as you zoom. A varifocal has to be refocused at every focal ...
