I don't know whether there's a more concise one, but this works to `ls` 
the ones that match:

ls -l *(e:'[[ $#REPLY == 30 ]] || reply=()':)

You could also wrap the expression there into a function:

globlen() { [[ $#REPLY == $GLOBLEN ]] || reply=() }
GLOBLEN=30
ls -l *(+globlen)

More info:

man zshall | less +/estring
