I'm pretty sure you're doing yourself an injustice there. We're all learning all the time as we find out new things and ideas to try and experiment with. Rome wasn't built in a day and you started with such enthusiasm. I've just been re-reading your early posts here and feel it's a shame you're abandoning ship so quickly.I am selling the camera etc because I realise now that I’ll never be the photographer I'd hoped to be earlier this year.

Yes John , I experienced the shutter shock myself when using speeds in the range 1/30-1/200. But I am talking simply about focussing. When using LV zoomed 100% the big screen on the K1 makes manual focussing so much easier than using the viewfinder. The image is much much bigger. No use at all of course when off the tripod or with a moving subject.

If i want to absolutely nail focus to the best of my ability on a subject i will use a tripod and LV viewed at 100%. with the lens wide open if needed. Tell me a better method?
From Sabas's test of liveview with electronic shutter, it might lead to a sharper image for more reasons than just focussing (seemed shutter vibration could have been an issue.)If i want to absolutely nail focus to the best of my ability on a subject i will use a tripod and LV viewed at 100%. with the lens wide open if needed.

The most accurate way to focus is to use live view. Either using the Contrast-Detect AF system, or by manually focussing and using the screen zoomed at 100%. This is because you are then detecting the focus point directly on the cameras sensor.
Trying to set a focus on the tiny screen is tricky, especially if one's sight isn't what it used to be. If you zoom in to 100% you can no longer see the whole image you're trying to frame so that's tricky too.The most accurate way to focus is to use live view.

Just as an aside, don't try and set the focus adjust using Contrast Detect in liveview as it's using a different focussing method to what is causing the TTL focus problem, so won't solve that. It has to be set using the TTL Phase Difference method.

The 24x24 mode is also available and will work with APS-C specific lenses without vignetting.
Try your APS-C lenses in FF mode and see if they work for you. Usually its possible to get extra width from them in FF mode, indeed some are based on FF designs eg the DA*60-250. Given one can see what one is taking its possible to adjust the zoom setting and crop the image accordingly. No harm will be caused by setting FF for an APS-C lens! Then even if it doesn't work as intended, the vignetting may actually add something to the photo or simply adjust it out in post processing.
Not withstanding, it makes sense to get FF lenses in the longer term as it makes things more predictable; there's some real bargains in older film lenses to be had.

PS: did anyone mention that you need to do the tests with the camera on a sturdy tripod with a head that can be firmly locked in place - otherwise you will never keep the single AF point on the target
I suppose technically you're right, but isn't how I do it! I normally hand hold the camera so if I detect I'm regularly getting a back/front focus issue due to my technique, I simply adjust the lens setting accordingly until the lens works right for me to eliminate the focusing issue. One gets a feeling for it taking real life photos which is what causes one to suspect it isn't right and needs adjustment.PS: did anyone mention that you need to do the tests with the camera on a sturdy tripod with a head that can be firmly locked in place - otherwise you will never keep the single AF point on the target
Its always possible to revert it to zero and start over again if need be! It is possible to over complicate things.

Doesn't sound like something you can fix yourself unless you have skills in that area, but suspect if you have you wouldn't be asking! I can't recommend a repairer as I have no idea as to your location.
Just to check it isn't something else (e.g. a camera problem) do other lenses work OK? Alternatively can you check the lens on another camera?

I also own an Olympus OM-D EM-5 DSLR and the focus point on that is spot on.
A mirrorless camera by definition is not a DSLR.
They are MILC cameras, though Panasonic coined 'DSLM' which I like better
As to DSLR, that's the abbreviation for Digital Single Lens Reflex which describes the fact that a mirror or prism transfers the image to a viewfinder. The Oly doesn't have a viewfinder and mirror or prism hence the DSLR description is not appropriate. I don't believe they make DSLR's any more.
