Filename generation does not happen inside the [[ normally.
In zsh >= 5.0.5, you can force globbing to happen by using the glob qualifier #q.
(requires extendedglob to be enabled)

% [[ -f *(#q.) ]]; echo $?
1

Since globbing can match multiple files, [[ -f will fail since more than one file
matches the glob. So you can also use the new qualifier Y to limit the results to
the first match.

% [[ -f *(#qY1.) ]]; echo $?
0
