From the Manufacturer
The new SP Series 35mm lens produces stunning high-resolution quality across a wide range of focusing distances. In particular, this lens features a milestone of proximity never before achieved with a standard lens – at a MOD of 0.2m*.
And with VC, photographers can now fully take advantage of the potential of optical performance from F/1.8 full open aperture. Furthermore, even in close-ups, the lens maintains a wide-angle perspective that will add context and story depth to your subject. The SP 35mm will keep pace with the photographer’s spontaneity – on the spur of the moment, with a handheld shot.
High Performance at F/1.8 Full Aperture
The open aperture is set to F/1.8 with optimized critical properties at a higher level: superb optical performance coupled with a VC system, a shorter MOD, and a well-balanced form factor. Rigorous simulation processes performed throughout the design phase are materialized in distinguished resolving power and beautifully-tuned background blur, a prominent feature to a fast-aperture, full-frame compliant optic.
Closest Focusing Distance in its Class
The SP 35mm (MOD: 0.2m) offers best-in-class close focusing*. A floating system design feature seamlessly optimizes image quality by shifting elements relative to the focus group in close shooting situations. Of the new SP series lenses, the 35mm lens offers unique opportunities enabling shooting like a wide-angle macro lens.* 35mm: Rated top among current 35mm fixed focal length interchangeable AF lenses for full-frame DSLR cameras excluding macro lenses (As of July 2015.

Ultrasonic Silent Drive (USD)
The USD actuator converts ultrasonic waves into rotational motion that delivers autofocus with responsiveness, accuracy, and speed without so much as a whisper. The photographer can easily use manual focus at any point while the AF system is operating without having to fumble for a switch.
Molded Glass Aspherical Elements
Two molded glass aspherical elements deliver planarity in field curvature. These elements ensure superb focusing uniformity over the entire field by compensating for spherical and comatic aberrations.
LD (Low Dispersion) Glass and XLD (eXtra Low Dispersion) Glass
To further compensate for chromatic aberrations, the new SP Series lenses use an LD element, and the 35mm lens combines one LD with an XLD element. Together these elements help deliver crisp, clear images without color fringing.
Even when stopped down two steps, the nine-blade diaphragm maintains its circular shape to deliver a nicely-tuned background blur.
Optimal Relative Illumination
The 35mm lens delivers exceptionally uniform illumination levels across the image field to avoid non-linear patterns or fall-off toward corners.
Constructed to prevent moisture from entering the internal mechanisms of the lens, the new SP line is sealed to allow photographers to shoot outdoors in adverse conditions.
Developed for industrial optics, fluorine coating offers long-lasting oil and water resistance to the lens. Moisture and smudges wipe away, making it easy to keep your lens clean.
