Reflection Of Helios Lens Stock Photo

Helios Russian: Ге́лиос was a brand of camera lenses, made in the USSR. The Helios-44 and Helios-40 are derivatives of the Carl Zeiss Biotar optical formula. As all lenses based on the Biotar formula, the Helios-44 and Helios-40 produce an unusual `swirly` bokeh effect to the out-of-focus background. The bokeh `circles` become more elliptical in shape as you move away from the center of the photo. This optical phenomenon gives images rendered by these vintage lenses a distinct character, which has created a cult following among fine art photographers.
