It brings a 5 inch screen, full waterproofing and a two day battery to bear, and as ever with Sony there's a focus on camera quality.
A massive 21.5 megapixel rear camera inherits the company's latest photo tech, including a quick launch app, instant auto focus and a dedicated camera shutter button. There's also 4K video on board and 5x zoom without a loss of image quality.
The M5 also includes a 13 megapixel front facing camera which is one of the highest rated around and also has fast autofocus and high dynamic range abilities.
The sequel to the popular M4 Aqua, the Sony Xperia M5 is available now in Ireland priced at free from EirMobile and Three.
