Key Features
  • APS-C | f/1.8 to f/16

A portrait-length prime featuring a compact design, the Yongnuo YN 50mm f/1.8S DA DSM Lens is designed for APS-C-format Sony E-mount mirrorless cameras. The lens's bright f/1.8 design suits working in low-light conditions and also enables increased control over depth of field for isolating subject matter. The optical design incorporates one low dispersion element, which helps to reduce chromatic aberrations and color fringing. Additionally, a nano multilayer coating has been applied to suppress flare and ghosting for improved contrast in strong lighting conditions. The coating also repels oil, water, and dust for easy cleaning. Balancing the optics is a DSM autofocus system, which promotes fast and quiet focusing performance to suit both photo and video applications.

Punto dulce en F5 , No es muy bueno para Video porque el autofoco falla, para foto el autoenfoque en oscuridad es lento e impreciso , va de maravillas a pleno sol, un bonito bokeh , en 1.8 tambin es muy ntido. le doy 4 estrellas por el precio

What range of wavelengths of light LESS THAN 400 ...

What range of wavelengths of light LESS THAN 400 nm does this lens transmit at least 50% of? At least 25% of?
Asked by: David
The following is not an answer to this question; instead, it is a clarification as to what I, who posted this question, am referring to. Please understand that while I am grateful for this question having been addressed, I was NOT INQUIRING as to the transmission by this lens of near Infrared light, i.e. that with a range of wavelengths between 700 and 1200 nm. Rather, I am inquiring as to the UV (aka the near Ultraviolet spectrum, in particular, UV-A light, which has an approximate range of wavelengths from 320 to 400 nm.
