We lent my 450D to my brother-in-law & his wife overnight. Hubby got a phone call today to confess that they had dropped the camera, while in the camera bag & had broken a lens filter. They replaced the filter & found no other damage, returning the camera to our house before we came home. They were not able to wait for us, as they had to travel 5 hrs home. I was thankful that they'd been honest with us & got a replacement straight away.

We found 2 new lens filters in the camera bag & the previous ones missing off both lenses, so figured both must have broken.

I am worried that if the fall was enough to damage two filters, while in the bag with lens caps on, could there be any possible damage to the lenses, or camera body functionality? The camera appears to be working fine, both lenses zooming in & out, focusing on auto settings.

My question is - is there anything I should be testing out to ensure no further damage was done? I've really only just started learning manual settings, so I don't know what to look for...

I appreciate any advice.
