People who are looking at the latest camera models from Sony may need to buy ink cartridges so they are able to get the best possible prints at home.

The organisation has unveiled the compact NEX-5N camera, which produces stills at a quality of 16.1 megapixels and is capable of full HD video.

It also offers manual focus, which could be even more important for those who know what they want to get from a snap.

As well as the NEX-5N product, Sony has shown off the SLT-A77 (a77) and SLT-A65 (a65) cameras, both of which are also new to the market.

They have the latest refinements in Translucent Mirror Technology by Sony, which the company argues makes them among the best in their class.

The a77 comes as the replacement for the acclaimed a700 DSLR, which could encourage those who are used to that camera to upgrade to the new machines.

Sony's announcement comes shortly after printer supplies maker Canon revealed its SX150 IS, which is on sale from September.
