58mm · f/2
The Helios-44M 58mm f/2 is a Soviet-era lens known for its distinctive swirly bokeh, especially with sunlit foliage backgrounds. Optically, it offers good micro-contrast and a 3D pop, but is soft wide open and lacks contrast out of camera. Build quality is solid metal and glass, but handling can be poor with loose aperture rings and stiff focus. It is very cheap and widely available, suiting photographers who enjoy characterful, vintage rendering and are willing to work around its quirks.
