The M.Zuiko Digital ED 17mm f/1.2 PRO lens is a twin to the 45mm f/1.2 PRO and carries most of the features barring the focal length and optical elements. What surprises us is how Olympus has added the same price tag to both the lenses.
Design and Build Quality
The M.Zuiko Digital ED 17mm f/1.2 PRO is built sturdy with an aluminium alloy body and hermetic sealing across the entire lens to make it dust-proof, splash-proof, and freeze-proof. The lens is light and compact and balances nicely with OM-D bodies. It features a useful Lens function (L-Fn) button that can be customised as a shortcut button. The 17mm PRO has a wide focus ring and uses a Manual Focus Clutch mechanism to instantly shift the focus mode between Auto and Manual.
The M.Zuiko Digital ED 17mm f/1.2 PRO provides a 35mm equivalent focal length of 34mm, which is useful for street photography, landscapes and product images. The lens provides feathered bokeh that renders the bokeh with smooth gradation for the out-of-focus background, achieved with the help of an ultra-high precision aberration measurement instrument.
The lens is constructed with 15 elements in 11 groups including six Extra-low Dispersion (1 Super ED, 3 ED, 1 ED-DSA, 1 EDA), one Super HR (High Refractive Index) and one aspherical element. The newly developed ED-DSA element incorporates both ED and DSA (Dual Super Aspherical) properties. This compensates for
