NOKTON 17.5mm F0.95 Aspherical

Amazingly large maximum aperture realized using a cutting-edge optical design

Features

The Nokton 17.5mm F0.95 is a wide-angle lens designed especially for the Micro Four Thirds format. This lens has a wide 64.6° angle of view (equivalent to a 35mm lens in 35mm full frame format) combined with an amazingly large F0.95 maximum aperture. An element with an aspherical surface ensures sharp imaging from maximum aperture.

Main Features

Amazingly large maximum aperture

The large F0.95 maximum aperture enables images to be captured using just the available light even in low light situations. The lens is also ideal for imaging at maximum aperture to utilize its shallow focus and beautiful bokeh.

Ultimate lens design

The optical configuration consists of 13 elements in 9 groups designed based on modern optical theory. The lens employs ultra-high refractive index glass and an aspherical element in pursuit of imaging performance. Even at maximum aperture, the lens captures sufficient light right up to the periphery of the image.

Minimum focus distance of 0.15 meters

Images can be captured as close as 15cm from the camera’s imaging sensor. With a reproduction ratio of 1:4, you can enjoy capturing images using the ultra-large maximum aperture macro lens-like character of this lens.

Diverse expressive power

At maximum aperture, the gentle and smooth bokeh makes the in-focus subject stand out and gives images a sense of three-dimensionality. And when the aperture is stopped down, images are extremely sharp, making diverse photographic expressions possible with this one lens.

Aperture click-stop switching mechanism

The aperture click-stop switching mechanism enables the aperture mechanism to be steplessly stopped down/opened up with no click-stop sound. This ensures that the sound of the aperture ring being operated is not recorded while capturing video and also enables a high level of depth of focus control by fine-tuning the aperture ring.

Dedicated Micro Four Thirds mount

Optics and mechanism designed especially to conform to the Micro Four Thirds standard. As it fully covers the size of the imaging sensor and is optimized for Micro Four Third sensors, this lens achieves excellent image quality.

Manual focus for reliable focusing

Employs a very precisely machined and adjusted all metal helicoid unit lubricated with high quality grease to realize smooth focusing operation with just the right amount of torque. This enables very precise focusing.
