Ana focalizează obiectivul pe peisaj.

Focalizează is the 3rd-person singular present form of a focaliza (to focus).

Because the subject is Ana, the sentence means:

• Ana focuses...
• or Ana is focusing...

Romanian present tense often covers both the simple present and the present continuous, so the exact English translation depends on context.

In this sentence, obiectivul means the lens (especially a camera lens), not objective in the English sense of goal.

Romanian obiectiv can mean different things depending on context, including:

• lens
• objective
• sometimes objective point/target

Here, because of focalizează and pe peisaj, the photographic meaning lens is the natural one.

The ending -ul is the Romanian definite article, attached to the end of the noun.

So:

• obiectiv = a lens / lens
• obiectivul = the lens

Unlike English, Romanian usually puts the at the end of the noun instead of before it.

Here, pe is a normal preposition, meaning something like on, onto, or toward, depending on context.

So pe peisaj means that the lens is being focused on the landscape.

This is not the same use of pe as in sentences like:

• Văd pe Ana = I see Ana

In Văd pe Ana, pe helps mark a specific human direct object.
In pe peisaj, it is simply a regular preposition.

Romanian often uses a bare noun after a preposition in places where English would naturally use the.

So:

• pe peisaj can still be understood as on the landscape / on the scene

Using peisajul would make the landscape sound more explicitly identified or more specifically definite:

• pe peisajul = on the specific landscape / on that landscape

Both can work depending on context, but the version without the article is not strange.

Grammatically, obiectivul is the thing being focused.
Pe peisaj tells you where or toward what it is being focused.

So the structure is:

• Ana = subject
• focalizează = verb
• obiectivul = direct object
• pe peisaj = prepositional phrase

That is why the sentence is closer to:

• Ana focuses the lens on the landscape

and not:

• Ana focuses the landscape

Yes. Romanian word order is fairly flexible, although the given order is the most neutral and straightforward.

Ana focalizează obiectivul pe peisaj sounds like a normal, plain statement.

You can move parts around for emphasis, but that changes the feel:

• Pe peisaj, Ana focalizează obiectivul.
  Emphasizes the landscape.

• Obiectivul îl focalizează Ana pe peisaj.
  More marked and much less neutral.

So for a learner, the original order is the best model to remember.

A rough English-friendly pronunciation is:

AH-na fo-ka-li-ZEA-zuh ob-yek-TEE-vul pei-SAZH

A few useful notes:

• Ana = AH-na
• ă in focalizează is a short central vowel, something like a relaxed uh
• obiectivul has the stress on -ti-: ob-yek-TEE-vul
• j in peisaj sounds like the s in measure

So peisaj sounds roughly like pei-SAZH.

Yes, it is understandable and natural, especially in a technical or photography-related context.

A Romanian speaker would understand it as something like:

• Ana is focusing the lens on the landscape.

In everyday speech, people might also use slightly different phrasing depending on what they want to highlight, but this sentence is perfectly workable Romanian.
