Blurry Photos with Olympus OM10 and Zuiko 50mm Lens 1.8

Hi,

So I just received a roll of film back using this setup - for reference I was shooting at midday with ISO 400 Ilford xp2 b&w. My aperture was set to f1.8, ISO was correctly set and I was using automode on the camera - which was showing around 250 - 1000 with the led in the viewfinder. Whilst I was looking through the viewfinder everything seemed in focus - I was aligning the two semi circles by manually zooming. However upon receiving the film it came back blurry and I'm not exactly sure why given the fact that when I was looking through the viewfinder it was in focus.

Some examples:

Does anyone have any experience with a similar issue?
