Today, I tried to take a picture with my wife's camera, and when I was done I went to put the lens cap on, but the outward part was facing the lens, and now the lens is scratched. Very, very expensive mistake for such a seemingly trivial accident, I feel.
I'm normally quite careful with the camera, but I'm not familiar enough with the lens cap to know which way is which on first glance.
Is there any type of lens cap that will stop itself short of destroying the lens if you accidentally put it on backwards because you're not paying attention?
Or should I just never touch the camera?
Thanks in advance.
