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 be available in 110 countries by the end of May.
With a starting price of $399/$499 (£277/£346), the new iPhone is the "most affordable" handset Apple has ever released, Apple said.
It also said the new iPad Pro would be available in three different storage sizes with an extra large 256GB version.
Pricing will begin at $599 for the smallest version and will ship in the US at the end of the month.
