KIPON Handevision IBELUX 40mm f/0.85 Lens for SONY E
This HandeVision IBELUX 40mmf/0.85 Lens is specifically designed for Sony E mount APS-C-formatmirrorless digital cameras, where it provides a 35mm-equivalent focal length of60mm. This manual focus prime lens is characterized by its exceptionally fastf/0.85 maximum aperture, which enables its use in a wide array of lightingconditions as well as provides extensive control over focus placement. Theoptical construction is comprised of 10 elements in 8 groups, including aconcave front element that helps to reduce chromatic aberrations and maintainsa central angle of incidence of 2.6° for sharp imaging and minimal distortionthroughout the aperture range.
The physical construction of thelens is set in an all-metal lens barrel, in which anodized aluminum alloy,brass, and stainless steel are used. The manual focus ring rotates 250° toenable precise focus setting to distances as close as 2.5′. Additionally, a10-blade diaphragm works to produce a circular aperture that contributes to anaesthetic out-of-focus quality to benefit selective focus and shallow depth offield techniques.
- Prime 40mm lens provides a35mm-equivalent focal length of 60mm when used on APS-C image sensors.
- A fast, bright f/0.85 maximumaperture is well-suited to working in difficult lighting conditions as well asfor controlling depth of field.
- Front concave lens element andsophisticated optical design helps to minimize chromatic aberrations andachieve notable sharpness.
- Manual focusing ring has a 250°focus throw, which enables precise positioning and critical refinement overfocus placement.
- All-metal lens barrel incorporates abuilt-in lens hood to both protect the front lens element and reduce lens flareand ghosting.
- Ten-blade circular diaphragmproduces an aesthetic out-of-focus quality that is pairs well with the fastmaximum aperture.
