Ρύθμισε εστίαση, ταχύτητα κλείστρου και βάθος πεδίου.

Ρύθμισε is the imperative form of the verb ρυθμίζω, which means to adjust, to set, or to regulate.

In this sentence, Ρύθμισε means something like:

• Set
• Adjust

More specifically, it is the 2nd person singular aorist imperative. That sounds technical, but the practical meaning is simple: it is a command to one person, often with the sense of do this / set this now.

So:

• Ρύθμισε = Set! / Adjust! (to one person)

A very common contrast is:

• Ρύθμισε = singular command
• Ρυθμίστε = plural command, or polite singular command

It is singular because Greek uses different imperative endings depending on whether you are speaking to:

• one person
• more than one person
• or one person politely

Here you have:

• Ρύθμισε = command to one person

If you wanted to say the same thing to multiple people, or politely to one person, you would normally say:

• Ρυθμίστε εστίαση, ταχύτητα κλείστρου και βάθος πεδίου.

So the ending changes:

• -σε → singular informal
• -στε → plural / polite

Greek often omits articles in short instructions, labels, menus, interface text, and concise commands.

So:

• Ρύθμισε εστίαση, ταχύτητα κλείστρου και βάθος πεδίου.

sounds like a compact instruction, similar to English menu or camera-setting language.

If you added articles, it would sound more explicit and a bit fuller:

• Ρύθμισε την εστίαση, την ταχύτητα κλείστρου και το βάθος πεδίου.

That is also correct.

The version without articles is common when the sentence is functioning like a brief instruction or command in a technical context.

They are the direct objects of Ρύθμισε, so they are in the accusative case.

Here is how they work:

• εστίαση = accusative singular
• ταχύτητα = accusative singular
• βάθος = accusative singular

For some nouns, especially many feminine nouns like εστίαση and ταχύτητα, the nominative and accusative forms can look the same. So even though the form does not change visibly, the grammatical role is still accusative here because they are the things being adjusted.

This is a very common Greek structure: noun + noun in the genitive.

• ταχύτητα = speed
• κλείστρου = of shutter

So literally:

• ταχύτητα κλείστρου = speed of the shutter

In natural English, that becomes:

• shutter speed

The word κλείστρου is the genitive singular of κλείστρο.

So:

• το κλείστρο = the shutter
• του κλείστρου = of the shutter
• ταχύτητα κλείστρου = shutter speed

Greek often uses this of X structure where English prefers a compound noun.

Yes, exactly the same pattern.

• βάθος = depth
• πεδίου = of field

So literally:

• βάθος πεδίου = depth of field

In English, that is usually said as:

• depth of field

Again, πεδίου is the genitive singular form of πεδίο.

So:

• το πεδίο = the field
• του πεδίου = of the field
• βάθος πεδίου = depth of field

This genitive pattern is extremely important in Greek, especially in technical vocabulary.

Both patterns exist in Greek, but in compact technical phrases, Greek often leaves out the article.

So:

• ταχύτητα κλείστρου = shutter speed
• βάθος πεδίου = depth of field

This is normal and idiomatic.

If you inserted the article, the phrase would usually sound more expanded or more specifically referential:

• η ταχύτητα του κλείστρου
• το βάθος του πεδίου

Those versions are grammatically fine, but they feel more like full descriptive phrases, while the article-less versions are the standard set terms.

This is similar to how English technical language often compresses expressions too.

Yes. εστίαση commonly means focus or focusing, especially in photography, optics, and camera settings.

Depending on context, it can refer to:

• the act of focusing
• the focus setting
• focus in a more technical or visual sense

In this sentence, it clearly means:

• focus as a camera setting

So the sentence is listing camera-related things to adjust:

• focus
• shutter speed
• depth of field

Yes, this is basically the same list punctuation pattern as in English.

The sentence lists three items:

• εστίαση
• ταχύτητα κλείστρου
• βάθος πεδίου

Greek commonly uses commas between earlier items and και before the last item:

• A, B και C

So this is completely normal:

• Ρύθμισε εστίαση, ταχύτητα κλείστρου και βάθος πεδίου.

It works just like:

• Set focus, shutter speed, and depth of field.

Greek usually does not use the Oxford comma in the same way English sometimes does, so the version without a comma before και is standard.

A rough pronunciation guide is:

• Ρύθμισε ≈ REE-thmee-se
• εστίαση ≈ eh-STEE-ah-see
• ταχύτητα ≈ tah-HEE-tee-tah
• κλείστρου ≈ KLEE-stru
• και ≈ keh
• βάθος ≈ VA-thos
• πεδίου ≈ peh-THEE-oo

Put together, roughly:

REE-thmee-se eh-STEE-ah-see, tah-HEE-tee-tah KLEE-stru keh VA-thos peh-THEE-oo

A few useful notes:

• θ sounds like th in think
• δ sounds like th in this
• αι is pronounced like e
• ει / οι / υ / η / ι usually sound like ee

The word order can change, but the given order is very natural.

Greek word order is more flexible than English because case endings help show grammatical roles. Still, some orders sound more natural than others.

This version:

• Ρύθμισε εστίαση, ταχύτητα κλείστρου και βάθος πεδίου.

is a normal, straightforward instruction.

You could rearrange the listed items if you wanted to emphasize a different one, but in ordinary usage there is no strong reason to do so. The verb-first order is also very common in commands.

So this sentence is a standard instructional pattern:

• Verb + objects

It sounds especially natural as instructional or technical language.

A native speaker would easily understand it as something like:

• a camera manual instruction
• a software or device command
• a checklist item
• a photography lesson instruction

Because the objects are listed without articles, it feels a bit more concise and functional than conversational speech. In everyday fuller speech, someone might more often say:

• Ρύθμισε την εστίαση, την ταχύτητα κλείστρου και το βάθος πεδίου.

But the shorter version is very normal in technical contexts.

A more conversational or fully spelled-out version would be:

• Ρύθμισε την εστίαση, την ταχύτητα κλείστρου και το βάθος πεδίου.

You might also hear wording with a slightly different verb depending on context:

• Ρύθμισε την εστίαση...
• Προσαρμόσε την εστίαση... if the sense is more adjust/adapt
• Άλλαξε την ταχύτητα κλείστρου... if the sense is specifically change

But for a neutral instruction meaning set/adjust these camera parameters, Ρύθμισε is a very good choice.

Here are the main dictionary forms:

• ρυθμίζω = to adjust, set, regulate
• εστίαση = focus, focusing
• ταχύτητα = speed
• κλείστρο = shutter
• βάθος = depth
• πεδίο = field

And the forms used in the sentence are:

• Ρύθμισε ← from ρυθμίζω
• εστίαση ← dictionary form already
• ταχύτητα ← dictionary form already
• κλείστρου ← genitive singular of κλείστρο
• βάθος ← dictionary form already
• πεδίου ← genitive singular of πεδίο
