På den ene siden: autofokus. På den andre siden: valg.

It sets up a contrast between two sides, aspects, or advantages.

The whole pattern is a very common Norwegian equivalent of on the one hand ... on the other hand.

So here, the sentence is presenting two contrasting points:

• på den ene siden = one side of the matter
• på den andre siden = the other side of the matter

It is often used when comparing pros and cons, two perspectives, or two features.

Because ene and andre are modifying the noun side, and the noun is in a definite phrase.

In this expression:

• ene means one / the one
• andre means the other

So:

• den ene siden = the one side
• den andre siden = the other side

This is just how Norwegian builds this kind of phrase. It is best learned as a set expression:

• på den ene siden
• på den andre siden

Because siden is the definite singular form of side.

Compare:

• en side = a side
• siden = the side

So:

• den ene siden literally contains the definite noun siden

In Bokmål, side can also appear with feminine forms in some contexts, so you may sometimes see sida instead. But på den ene siden / på den andre siden is extremely common and very standard.

Because this is an idiomatic expression: på ... siden.

Literally, it is something like on the one side / on the other side. English uses a different fixed expression, on the one hand / on the other hand, but the function is the same.

So this is not something you would usually translate word-for-word. It is better to remember the whole chunk:

• på den ene siden
• på den andre siden

This is a very useful distinction in Norwegian.

• en annen side = another side / a different side
• den andre siden = the other side

So in this sentence, the meaning is specifically the other side of a two-part contrast, which is why andre is used.

A simple way to remember it:

• annen often means another
• andre often means the other or appears in plural/definite-type environments

Because this is a shortened, slogan-like, headline-style sentence.

Norwegian often omits words in titles, ads, captions, and punchy promotional language. The colons make it feel like two labels or two highlighted features:

• På den ene siden: autofokus.
• På den andre siden: valg.

In more ordinary prose, you would usually have a fuller sentence with a verb, for example:

• På den ene siden har du autofokus, på den andre siden har du valg.
• På den ene siden får du autofokus, på den andre siden får du valgmuligheter.

Exactly which verb you choose depends on the context.

Valg is a noun. Its basic dictionary form is:

• et valg = a choice

It can also mean election in other contexts, but here it clearly means choice or selection.

In this sentence, it appears without an article, which gives it a slightly abstract or label-like feel. That is common in short advertising or headline language.

Compare:

• et valg = a choice
• valg = choice / choices / selection, in a more general or abstract sense

Depending on context, a fuller version might also use words like:

• valgmuligheter = choices, options
• alternativer = alternatives, options

Yes. Autofokus is used in Norwegian as well, and it means the same thing as English autofocus.

It is one of many technical or international words that look very familiar to English speakers. So in this sentence, autofokus is not unusual at all.

You can use it by itself, but it usually suggests that another contrasting point is coming.

For example:

• På den ene siden er det praktisk. = On the one hand, it is practical.

A listener or reader will often expect a second point after that.

Very often, though, the full pair is used together:

• På den ene siden er det billig, på den andre siden er kvaliteten dårligere.

So yes, it can stand alone, but it most naturally introduces a contrast.
