[DPR] Olympus 45mm and 17mm F1.2 Pro lenses emphasize bokeh quality

Olympus has announced 17mm and 45mm F1.2 Pro primes, offering high-end fast 35mm and 90mm equivalent lenses. The lenses use the same 60mm filters that the existing 25mm F1.2 Pro uses and, like that lens both are weather sealed and dust proof.
The two lenses expand the company's series of F1.2 lenses, which are equivalent to 35 and 90mm F2.4 lenses for full frame. This allows Micro Four Thirds users to achieve very shallow levels of depth-of-field at the focal lengths where they need this capability. The lenses are designed to be consistent in size with one another.
Olympus says it's focused the design not just on achieving sharpness but also on providing attractive bokeh. It says its research showed that bokeh with a soft edge produces the most attractive result, producing a smooth transition from in-focus to out-of-focus regions, and with minimal risks of interference patterns occurring in backgrounds.
To achieve this, both lenses are designed so that spherical aberration is not fully corrected (that would give completely uniform bokeh). Instead it focuses peripheral light rays slightly in front of the plane of focus, giving a soft roll-off to the edges of the bokeh. This, they say, is how many much-loved 'classic' lenses gave desirable, '3D' rendering.
The 17mm lens includes a unique ED-DSA element, which has dual aspherical lenses formed from soft and hard-to-work extra low dispersion glass. They claim to be the only company currently able to do this.
The company also highlights that its cameras should be able to achieve very high levels of focus precision even with off-center points. Both lenses also have the snap-back focus clutch system, so that videographers can manual focus with a linear focus response.
Olympus mentions that there's been a trend towards bokeh-optimized primes in recent years but says its design approach gives attractive bokeh without any of the light loss causes by the use of apodization filters in Fujifilm's APD or Sony's STF lenses.
Each lens will cost $1200. The 45mm will go on sale in late November, and the 17mm will be available in late January 2018.

BEAUTIFUL BOKEH: TWO NEW OLYMPUS LENSES EXPAND THE M.ZUIKO PRO F1.2 PRIME LINEUP

M.ZUIKO Digital ED 17mm F1.2 PRO and M.ZUIKO? Digital ED 45mm F1.2 PRO Offer Smooth Feathered Bokeh and High Resolution at the Brightest Aperture
CENTER VALLEY, PA., October 25, 2017 ? Olympus expands its M.ZUIKO F1.2 PRO prime lens lineup with the new M.ZUIKO Digital ED 17mm F1.2 PRO (34mm focal length in 35mm equivalent) and the M.ZUIKO Digital ED 45mm F1.2 PRO (90mm focal length in 35mm equivalent). These Micro Four Thirds? system lenses join the currently available M.ZUIKO Digital ED 25mm F1.2 PRO (50mm focal length in 35mm equivalent) to deliver outstanding resolution and beautiful feathered bokeh at a maximum aperture of F1.2.
The M.ZUIKO Digital ED 17mm F1.2 PRO and M.ZUIKO Digital ED 45mm F1.2 PRO give M.ZUIKO PRO lens users more flexibility in low-light environments as well as an extraordinarily shallow depth-of-field. Each is designed to achieve a new level of depictive performance, delivering three-dimensional images that represent subjects as they appear in the real world through a combination of feathered bokeh and sharp resolution.
By focusing not only on the bokeh?s size but also its quality, each lens produces a feathered bokeh effect that better emphasizes the main subject and allows it to stand out within the image. The shallower depth of field produced at F1.2 is especially ideal for portrait photographers.
The newly developed ED-DSA lens, which possesses the characteristics of both an ED (Extra-low Dispersion) lens element and a DSA (Dual Super Aspherical) lens element, is incorporated in the M.ZUIKO Digital ED 17mm F1.2 PRO. The ED-DSA lens compensates for common wide-angle lens issues, including chromatic aberrations, distortion and color bleeding on the image periphery.
Like other lenses in the M.ZUIKO PRO series, the M.ZUIKO Digital ED 17mm F1.2 PRO and M.ZUIKO Digital ED 45mm F1.2 PRO feature compact, lightweight construction and a dustproof, splashproof, freezeproof (to 14°F/-10°C) design, giving photo enthusiasts and professionals the ability to capture brilliant images in a variety of shooting conditions.
U.S. Pricing and Availability
The M.ZUIKO Digital ED 45mm F1.2 PRO will be available late November 2017, while the M.ZUIKO Digital ED 17mm F1.2 PRO will be available late January 2018. Both lenses will have an estimated street price of $1,199.99 USD/$1,499.99 CAD.

Main Features
1. Depictive performance that delivers feathered bokeh and outstanding resolution
Feathered bokeh provides an ultra smooth transition from the sharp to the defocused areas of the image to provide an overall softer background. This results in a subject that stands out with lifelike dimensionality.
In the M.ZUIKO Digital ED 17mm F1.2 PRO, there are 15 elements in 11 groups, including specialized lens elements like the newly developed ED-DSA lens. The ED-DSA lens element, which possesses the characteristics of both an ED (Extra-low Dispersion) lens and DSA (Dual Super Aspherical) lens, reduces the overall weight and the number of lens elements. This design effectively compensates for various types of aberrations that tend to occur in wide-angle lenses, such as chromatic aberration, distortion and color bleeding on the image periphery (magnification chromatic aberration).
The M.ZUIKO Digital ED 45mm F1.2 PRO contains three optimally placed and bonded lens elements, including one ED lens, which compensate for typical problems on wide-aperture lenses like out-of-focus color bleeding (axial chromatic aberration) and peripheral color bleeding (magnification chromatic aberration). The extensive use of special lenses incorporated into 14 elements in 10 groups results in superb optical performance and feathered bokeh effects, even at the widest aperture setting.
Both lenses use the same Z Coating Nano technology as the M.ZUIKO Digital ED 25mm F1.2 PRO for sharp, clear image quality that significantly reduces ghosts and flares that tend to occur in backlit images.
2. Fast, high-precision AF
Both lenses are equipped with the MSC (Movie- and Still-Compatible) autofocus mechanism that provides virtually silent and smooth high-speed focusing performance, even when using the maximum aperture of F1.2. Additionally, there are no AF point limitations, even at the widest aperture, due to the On-Chip AF system in all Olympus OM-D? and PEN? cameras.
Using Face Priority or Eye Priority AF, two modes which are highly regarded by professional portrait photographers, brings out the true power of these large-aperture lenses.
3. Compact, lightweight construction and dustproof, splashproof and freezeproof (14°F/-10°C) performance
The M.ZUIKO PRO F1.2 prime lens lineup is exceptionally compact, lightweight and provides unrivaled mobility, dustproof, splashproof and freezeproof (14°F/-10°C) performance consistent with the M.ZUIKO PRO series. A uniform lens filter diameter across the three F1.2 lenses allows for use of the same lens filters, such as protection filters and PL filters.
Other Features

• Excellent close-up shooting: The M.ZUIKO Digital ED 17mm F1.2 PRO has a minimum focusing distance of 20 cm and a maximum image magnification of 0.15x (35mm equivalent: 0.3x), while the M.ZUIKO Digital ED 45mm F1.2 PRO has a minimum focusing distance of 50 cm and a maximum image magnification of 0.1x (35mm equivalent: 0.2x), providing outstanding close-up shooting performance.
• Premium design: Each lens was designed with the professional photographer in mind. The focusing ring placed at the front of the lens makes focusing easier when paired with the large grip of the flagship OM-D E-M1 Mark II camera. The L-Fn Button is located on a gently curving surface to make it comfortable to access. The MF Clutch mechanism allows the photographer to instantly switch between auto and manual focusing mode by pulling the focusing ring toward the camera body.
