Passive? No. There's nothing passive here, because there is no agent either implicit or explicit (i.e., there is nobody who is doing something).
focused is an adjective. Be careful. Not every word with
-ed is a verb in every sentence where it occurs. These two sentences are just the same statement in two different tenses. Note these:
John is ... [present]
John was ... [past]
John will be ... [future]
John has been ... [present perfect]
John had been ... [past perfect]
Complete any of the phrases above by adding any of these:
frightened of snakes, interested in science, focused on his studies, tired of reading, fascinated by insects, bored with grammar.
None of the resulting sentences has a passive construction.
