Opteka 6.5mm f/2 HD MC Manual Focus Fisheye Lens for Canon EF-M Mount APS-C Digital Cameras

ADVANCED OPTICS: Featuring an optimized design, this lens uses a series of 6 optical glass elements (one SD super-low dispersion) in 5 groups to reduce chromatic and spherical aberrations throughout the aperture range. A high definition anti-reflective coating suppresses lens flare and ghosting for increased contrast and color fidelity.

SOLID CONSTRUCTION: Full metal body, aperture ring and rear mount allow this lens to withstand wear and tear much better than plastic lenses while commanding a rugged, solid feel when using.

ULTRA-WIDE VIEW: 6.5mm which translates to 10.4mm on Canon EOS-M APS-C, which produces a strong visual distortion intended to create a wide panoramic or hemispherical image. This type of effect complements extreme sports or special effect photography.

DIFFRACTION EFFECTS: Sunstars are a fantastic way to bring a feeling of drama and excitement to a boring sky. A 9-blade aperture diaphragm delivers beautiful, sharp 18-point sunstars which makes photographs visually appealing.

COMPATIBILITY: Can be used on all Canon EOS M series mirrorless digital cameras including M100, M10, M6, M5, M3, M2 and EOS-M.
