Cosina has introduced the Voigtlander 50mm f/1.5 Heliar Traditional lens for VM-mount that it says was designed in “pursuit of a classical picture that trendy lenses would not have.” The optical design is deliberately imperfect to imitate a real classic lens and present numerous aberrations.
In brief, the Voigtlander 50mm f/1.5 Heliar Traditional has all of the hallmarks and desired options of a classic lens, however is model new.
The corporate says that the bokeh mixed with coma flare and a single coating end offers the lens a singular character with the way it renders pictures. That is in fact exacerbated by the broader apertures of the lens however might be toned down by closing the aperture to f/4 the place the corporate say the efficiency is “equal” to that of different Voightlander VM-mount 50mm lenses.
The “basic” nature of the lens and its imperfections is as a result of comparatively easy optical development: it’s made up of six components in three teams. Cosina says the optical design is made to deliberately specific aberrations when extensive open and offers a “classical bokeh and flare not present in trendy lenses.” The aforementioned single coating on the floor of the spherical lens is intentional and Cosina says this reproduces a classical shade tone that existed earlier than multi-coating grew to become frequent and the norm.
The aperture is open at its widest at f/1.5 — which Cosina says is a bigger aperture than the restrict of helia kind lenses — and its minimal aperture is f/16.
This guide focus lens has an all-metal focus ring that’s knurled with a diamond sample that Cosina says was made utilizing a particular slicing device to enhance operability and stop slipping in each the rotation and optical axis instructions. Additionally, along with sensible causes, the corporate says the sample appears to be like good. Cosina has additionally used an all-metal helicoid unit that has been processed and adjusted with excessive precision to supply a easy focusing operation with simply the correct amount of torque.
The bayonet-type VM mount is appropriate with the Leica M-mount and the lens helps a full-frame 35mm format. The Cosina Voigtlander 50mm f/1.5 Heliar Traditional can be launched in September for 90,000 yen, or about $820.
