7Artisans M50mm F1.1 Full Frame Lens - Leica M Mount - Silver

The 7Artisans M50mm F1.1 lens has an optical system consisting of 7 elements in 6 groups and is based on the Sonnar formula. It includes two high refraction optical elements of index 1.9 to improve picture quality and lens portability. Our R&D process involved analysis of field curvature and image astigmatism influence on the image’s out of focus areas. Numerous corrections and improvements were made resulting in a higher quality image. Using the lens wide open at an aperture of F/1.1 delivers soft and pleasant bokeh. Stopped down to F1.4, sharpness is improved while keeping smooth out-of-focus areas. Repetitive corrections of spherical and chromatic aberration lead to precisely controlled bokeh shape, and good contrast and sharpness in the focus area of this large aperture lens.

CA Proposition 65

Attention to all California residents, Proposition 65 or officially known as, the Safe Drinking Water and Toxic Enforcement Act of 1986, is a law that requires warnings be provided to California consumers when they might be exposed to chemicals identified by California as causing cancer or reproductive toxicity. The warnings are intended to help California consumers make informed decisions about their exposures to these chemicals from the products they use. The California Office of Environmental Health Hazard Assessment (OEHHA) administers the Proposition 65 program and publishes the listed chemicals, which includes more than 850 chemicals. August 2016, OEHHA adopted new regulations, to go into effect on August 30, 2018, which changes the information that is required in or on Proposition 65 warnings.

We want you to know and be aware of our product safety and Midwest Photo is taking all of the necessary steps to comply with the applicable safety and health requirements made by this Proposition 65.

WARNING: This product may contain chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.

This disclaimer can be found on the product pages on our website under the Additional Information tab which appears below the product description. It is listed on all product pages to ensure that our customer is aware of the warnings put out by our suppliers so you can know the precautions before purchasing.
