Yes, they extend out to completely cover/protect the contacts. They
also have a rubber O-ring that help with some friction to keep the cap
from turning and keeps any dust from getting to be back of the lens.

I've had good luck with caps by OP/TECH USA from Amazon. Over the years I've
used both their singles and doubles. Never had one come loose or fall off.

I've found there to be a tremendous range in both quality and price of K-mount
back caps for lenses. I have not found there to be consistent correlation
between quality and price though. Some of them will tighten down nicely and
stay attached, others will stay loose and just fall off.
Has anybody found good deals on quality K-mount back caps?
