<p>Hi!<br> I recently bought an Om 4 from 'The Bay', at first all seemed well, then after a little while I noticed that it was firing one shot off at the required speed e.g. 1 sec. and this was followed by an exposure that was either flash 1/125 or it's top speed 1/2000 of a second. No matter what I do I cannot seem to rectify this. I've naturally changed the batteries in case it was conserving energy LOL! :-) - The OM4?!*<br> Thanks a million for reading this - hopefully with THE answer.<br> Best Wishes to You All.<br> Graham.</p>
