Allowing shots with pleasing proportions of the human face, this prime lens is the perfect choice for portraits. With outstanding feathered bokeh at a maximum aperture of f/1.2, professional photographers can rely on precision technology and attention to detail in the design to capture the true beauty of their subject.
The M.Zuiko Digital ED 45mm f/1.2 PRO is a medium telephoto lens and the design of the back focus and relay lens system allowed a reduction in the number of lens elements required, resulting in a very compact, light-weight lens. Olympus has used optimally placed lens elements to effectively compensate for abberations such as out-of-focus color bleeding a common problem on large-aperture lenses as well as peripheral color bleeding. Photographers can enjoy excellent optical performance which delivers feathered bokeh effects and accurately reproduces details even at the widest aperture setting.
The lens also features Z Coating Nano technology for sharp, clear image quality that significantly reduces ghosts and flares that tend to occur in backlit shots.
Olympus M.Zuiko Digital ED 45mm f/1.2 PRO Lens in Detail
Depictive performance
The M.Zuiko f/1.2 PRO prime lens series delivers feathered bokeh and outstanding resolution using an optical design that prevents a significant reduction in light. This bokeh style transitions smoothly from the in-focus to the out-of-focus and gives photographers a smoother, softer overall background bokeh which adds depth of field and makes the subject stand out more beautifully, without sacrificing any resolution.
Fast and high-precision AF
The Olympus fast, high-precision auto focus is at the heart of the design philosophy for the M.Zuiko f/1.2 PRO prime lens series. The f/1.2 PRO lenses are class leading; delivering high speed performance to ensure that photographers never miss that vital shot.
When paired with the OM-D E-M1 Mark II, professional photographers can rely on fast, high-precision coverage of their subjects. Due to the advantages of mirrorless cameras when it comes to autofocus with large aperture lenses, the E-M1 Mark II's 121 point all-cross type On-chip Phase Detection AF sensor provides edge to edge, breath-taking pictures even at f/1.2.
Despite being large aperture lenses, a lightweight focusing unit allows the MSC (Movie and Still Compatible) mechanism to facilitate high-speed, high-precision still image autofocusing and silent, smooth autofocusing for movies in all of the M.Zuiko f/1.2 PRO lenses.
Close-up shooting
The f/1.2 PRO prime lens series joins many other M.Zuiko lenses, to give photographers exciting close-up shooting opportunities which further enhances the beautiful bokeh, covering a larger area.
The M.Zuiko Digital ED 45mm F1.2 PRO has a closest focusing distance of 50cm and a maximum image magnification of 0.1x (35mm equivalent: 0.2x).
Premium design
Olympus designed the f/1.2 PRO primes to give photographers a series of lenses which have a premium feel, high functionality and superior operation, fitting of a M.Zuiko PRO lens from Olympus lenses.
Understanding the importance of the ease of use, Olympus has created a common design and layout of the control section, so that photographers can concentrate on shooting without interruption even when changing the lens between shots.
The focusing ring has been positioned at the front of the lens to make focusing easier especially when paired with the large grip of the OM-D E-M1 Mark II. The L-Fn button is situated on a gently curving surface which makes it easy to access. The MF Clutch mechanism allows photographers to instantly switch between auto and manual focusing mode by pulling the focusing ring towards them.
By making the overall length and the maximum diameter of each lens almost the same size, Olympus has cleverly created a series of lenses which are compact and light-weight, perfectly suited to the OM-D camera range.
