Ας πάρουμε τρίποδο, κάρτα μνήμης και φωτογραφικό φλας.

ας is a very common particle used to make suggestions, usually translated as let's when it goes with a we form.

So:

• Ας πάρουμε = Let's take / let's get

It does not literally mean let us in a formal English sense; in everyday Greek, it is the normal way to suggest doing something together.

Examples:

• Ας φύγουμε. = Let's leave.
• Ας περιμένουμε. = Let's wait.

Because after ας, Greek usually uses the subjunctive form, not the ordinary indicative form.

The verb is παίρνω = I take / get.
Its subjunctive form here is να πάρουμε or, with a suggestion, ας πάρουμε.

So:

• παίρνουμε = we take / we are taking
• ας πάρουμε = let's take / let's get

This is a very important pattern in Modern Greek:

• ας + subjunctive

In this sentence, πάρουμε is the 1st person plural form: we.

Yes. πάρουμε comes from παίρνω.

This verb is somewhat irregular because different forms use different stems:

• παίρνω = I take
• πήρα = I took
• να πάρω = to take / that I take
• να πάρουμε = that we take / for us to take

So the παιρ- part in the present changes to παρ- / πάρ- in other forms. This is normal for this verb and just has to be learned as part of its pattern.

Greek often leaves out the article in lists like this, especially when you mean something general or indefinite.

So:

• τρίποδο, κάρτα μνήμης και φωτογραφικό φλας

means something like:

• a tripod, a memory card, and a camera flash

English requires a here, but Greek often does not.

You could include articles in some contexts, but without them the sentence sounds very natural, especially for a shopping/checklist-style suggestion.

They are in the accusative case because they are the direct objects of πάρουμε.

We are taking/getting what?

• τρίποδο
• κάρτα μνήμης
• φωτογραφικό φλας

In Modern Greek, some nouns look the same in nominative and accusative, so the case is not always obvious from the form alone. But grammatically, these nouns are functioning as accusative objects.

κάρτα μνήμης literally means card of memory, which is how Greek says memory card.

Here:

• κάρτα = card
• μνήμης = of memory

So μνήμης is in the genitive singular because it shows what kind of card it is.

This is a very common Greek pattern:

• X + genitive = X of Y / a compound noun phrase

Examples:

• ζώνη ασφαλείας = seat belt, literally belt of safety
• μηχανή καφέ = coffee machine, literally machine of coffee

So κάρτα μνήμης is a standard noun combination.

φωτογραφικό is an adjective meaning photographic or for photography.

So:

• φλας = flash
• φωτογραφικό φλας = photographic flash / camera flash

The adjective φωτογραφικό agrees with the noun it describes. Since φλας is neuter singular here, the adjective is also in the neuter singular form:

• φωτογραφικός = masculine
• φωτογραφική = feminine
• φωτογραφικό = neuter

Greek often uses this kind of adjective where English prefers a noun modifier, like camera flash.

In this sentence:

• τρίποδο is neuter
• κάρτα is feminine
• μνήμη is feminine
• φλας is usually treated as neuter in this use
• φωτογραφικό is neuter because it describes φλας

This matters because adjectives and articles in Greek must agree with the noun's gender, number, and case.

A helpful pronunciation guide is:

As PÁ-rou-me TRÍ-po-tho, KÁR-ta MNÍ-mis ke fo-to-gra-fi-KÓ flas.

A few notes:

• Ας sounds like as
• πάρουμε is stressed on πά
• τρίποδο is stressed on τρί
• κάρτα is stressed on κάρ
• μνήμης is stressed on μνή
• φωτογραφικό is stressed on the last κό
• και is usually pronounced ke in normal speech

Also:

• δ in τρίποδο is the soft th sound from this
• νήμ in μνήμης may feel unusual for English speakers because of the mn cluster

Usually, yes. In a simple list, Greek works much like English:

• item 1, item 2 και item 3

So here:

• τρίποδο, κάρτα μνήμης και φωτογραφικό φλας

This is the normal way to say tripod, memory card, and flash.

You do not normally repeat και before every item unless you want a special rhetorical effect.

Yes, depending on context. The verb παίρνω is very broad and can mean things like:

• take
• get
• pick up
• sometimes buy

So ας πάρουμε could mean:

• let's take
• let's get
• let's buy

The exact meaning depends on the situation. If people are preparing for a trip, it may mean let's take. If they are in a shop, it may feel more like let's buy or let's get.

Not with exactly the same meaning.

• ας πάρουμε = let's take/get
  This is a direct suggestion.
• να πάρουμε by itself usually needs a larger structure or different context, such as expressing purpose, possibility, or dependence on another verb.

For a straightforward suggestion in Greek, ας + subjunctive is the most natural pattern.

So in this sentence, Ας πάρουμε... is the correct choice for Let's take/get...
