Focus errors in the OM-1 with manula focus lenses

There seems to be a problem with the OM-1 when you use a purely manual focus lens. If you set the focus using the focus scale on the lens the camera at times gives a blurred image with about a 1px blur thus reducing the sensor resolution less than 5Mpx. This is most noticeable with fisheye lenses such as the Samyang and Mieke but will also happen with other lenses too. There won't be a problem if you use the sensor peaking etc for focus but that isn't practical for fisheye lenses.

Has anybody else found the same issue and if so please post.I suspect OM have an error in their control system as it doesn't occur in the EM1Mk2 or Mk3 and cannot be a lens issue.
