I am having random but regular problems with the original kit 18-70 lens.
on depressing the shutter release button the message 'no lens attached shutter is locked appears'.
factors that may be relevant/important.
1. other lenses, 50mm prime, 70-200 etc are working fine, so assume it must be a lens not body issue.
2. sometimes a simple turning off an on again will clear the problem, if only for a short time.
3. sometimes the problem prevents shooting on any setting, sometimes it only prevents shooting on certain settings. for example this morning i could shoot on manual, but not on auto or any scene setting.
4. despite point 1 that other lenses are working, i have followed advice on checking and cleaning camera and lens contacts and mounting ring etc.
if anybody has any ideas or solutions it would be very much appreciated.
