ls(1) will only print the names of files which exist, so the
test -f is not necessary. fname will not be set if there are
no *.log files.

however, ls will print an ugly error message to stderr, so

  2>/dev/null

may be advised. also, if *.log returns a directory, ls will
print out a list of its contents, which is not what you want.
ergo:

  for fname in `ls -d *.log 2>/dev/null`
  do
    echo "${fname} exists"
  done
