Completely Dejected (auto focus K5)
Yes, I did indeed read the post. The fact that the error was consistent suggests the adjustment was not being made as per the instructions, as the eye tends to compensate. Thtat's why it's necessary for there to be a blank or defocused image. Removing the lens is another way to achieve this.

Well when it gives the same error to the front focus both ways it is.

Well when it gives the same error to the front focus both ways it is. Except the correct adjustment for your eye is probably not at either extreme, but somewhere in between (or if you have poor eyesight, somewhere off the scale entirely). The only meaningful result is when it's correctly adjusted fr...

i think your on cross purposes here, John is saying the dioptre has to be adjusted to your eye sight by looking through the viewfinder at a blank white sheet of paper,card,wall or whatever as long as it is plain and light enough to see the focus target then move the dioptre until the focusing target...

Completely Dejected (auto focus K5)
Going round in circles a bit, I'll just sum up - I experimented extensively (a few hours) with manual focus. I set the diopter as advised in the manual by looking at a plain wall. The camera front focused - that is words that were readable by looking through the lens were unreable in the image. ...

My feeling is that you're totally misunderstanding something basic. The purpose of adjusting the eyepiece dioptre has nothing to do with the lens focusing, so forget that for a moment. To focus accurately on anything manually, that is by looking to see when it's sharpest, your eye needs to be at res...

Daydreamjay, if the lens will not focus manually either, then you have a fault somewhere. Maybe there is a misalignment of either the position of the sensor, or the position of the focussing screen. I suspect it's the focussing screen, because if it looks in focus through the lens during a manua...

Have you tried any shots with Live view?...... Zoom to full extent (I think it's 10x or 12x and slowly MF the lens, take a few shots. Then set lens to AF and use LV and Contrast Detect, you may have to change something in the menu. Just out of curiosity I tried this afternoon with available light...

But his earlier post (with the newspaper shots) show that his problem with the camera's focussing is that what looks in focus in the viewfinder manually focussed comes out focussed well in front of what he is seeing. He also checked across the range of dioptre settings in case it was his own vision...

LV should be perfect, so a test using it would indicate that the viewfinder focusing screen needs shimming.

In his newspaper shots, Live View was indeed the closest 'in focus' shot, so I think you are right. Time for him to seek a repair, or sell up and move to Canon then.

At this stage I would like someone local to me to give me a second opinion by having a go with my camera. Are any users in the West Yorks area?

At the risk of jumping in without reading the whole thread... The diopter setting is not intended to focus the image... It compensates for your eye's ability to focus on the focus screen. I find the best way to accomplish that is to simply remove the lens altogether and look through the viewfin...

East Ardsley, I'm sure we could arrange a meet in the New Year and get it sorted for you, try it with some different lenses etc.

The diopter slider on the K-5 is a pain to use, K-r one much easier

Please read this Go to the following chapter... 2.5) Be careful about autofocus The K-5/Pentax is not the only camera/system that suffers in these conditions.
