Re: focus issues with polarising filter

Well, it's difficult to say on the small images we post in the group, but the one titled Leighton Moss seems sharpest in the areas closer to the camera, I'd hazard a guess that the focus point was nearer than 60 ft away, so your depth of field wouldn't have included objects either close to the camera or in the far distance.

The one titled Constantine Bay well the hyperfocal distance would have been about 10ft (which if you focussed on it) would give you anything from about 4ft to infinity as sharp.

But I may be totally wrong (a good exif viewer will tell you - probably - how far away the camera thought the focus point was)
