Apple has announced smaller versions of the iPhone and iPad Pro at an event hosted in San Francisco and streamed online.
The iPhone SE has the same processing and graphics performance of the larger Apple 6S, the firm said, and can capture 4K video.
The new iPad Pro will have a 9.7 inch screen – the same size as the original iPad.
The iPhone SE will will be available in 110 countries by the end of May.
With a starting price of $399 and $499 the new iPhone is the “most affordable price ever” for a brand new handset, Apple said, adding that it sold 30 million four-inch handsets last year.
