A natural 38 mm equivalent view

On APS-C, 25 mm corresponds to approximately 38 mm on full frame. It is a versatile choice for street, documentary, interiors, still life and environmental portraits.

Real photographs made with the lens

Original manufacturer samples demonstrate colour rendering, fine detail and natural perspective on cameras using the same mount system.

F1.7 for low light and subject separation

Nine aperture blades help create rounded background blur, while the F1.7 aperture makes shooting indoors and in fading light easier.

Quiet focusing for stills and video

The lead-screw STM motor focuses quickly and quietly, supports eye and face detection, and offers low focus breathing for video work.

A carefully designed optical formula

Twelve elements in ten groups include one ED, two HR and two aspherical elements. The manufacturer diagram colour-codes the glass types used to control chromatic aberration, distortion and contrast loss.

Detail from centre to edge

The manufacturer MTF chart describes contrast and fine-detail transfer from the centre towards the image edge. Solid and dashed curves represent sagittal and meridional directions at different spatial frequencies.

Ready for everyday work

A metal mount, water-resistant front coating, 52 mm filter thread, EXIF transmission and USB-C firmware updates complete the compact design.
