I've seen pinhole lenscaps for sale, but you can make your own pinhole 
lenscap for any camera...just drill a hole in the middle of the lenscap 
then attach a pinhole over that.  Simple.  Just remember to take the 
lenscap off your lens BEFORE you start drilling.  :)

If you buy a pinhole someone else made it'll probably be more precisely 
round and you'll know the exact diameter and can therefore calculate the 
f/stop and figure out exposure.  If you make your own using a pin and an 
alumin(i)um pie pan, you have to experiment with exposure.  But, then you 
made your own!
