Whoa, could this be the Leica buster?????? 19 lenses, 14 groups, there must be something going on.

It better be amazing cause the 25mm 1.8 is already great and cheap. For $1000 plus it has to be truly great.....it probably will be knowing Olympus though.

Wish they didn't do the Pro thing though and just make the best lenses they can at a price between this and the cheaper ones.

Excellent resolution performance from the widest f1.2 aperture

To ensure high-resolution performance from the center to the edges of the image, even at the widest aperture of f1.2, 19 lenses have been used in an effective layout to suppress all types of aberrations. Color bleeding (on-axis chromatic aberration) is suppressed by using a Super ED lens and two ED lenses. When combined with the color-canceling effects of an E-HR (special high refractive index) lens and HR (high refractive index) lens, peripheral color bleeding (magnification chromatic aberration) is effectively corrected.

Z Coating Nano lens coating technology maintains sharp, clear image quality. This advanced coating significantly reduces flare in backlit situations, optimizing shooting when strong light sources are present in the frame.

Beautiful defocusing effects

The lens design effectively eliminates chromatic aberration in focused areas as well as defocused areas to achieve a smooth transition from the subject to the background. When paired with the lens’s shallow depth of field and beautiful circular bokeh at the maximum aperture, images have a natural, three-dimensional appearance.

Fast and accurate focus point capture

The advanced optical design provides a single focusing lens element for fast and accurate focus point capture. The MSC mechanism enables high-speed, high-precision still image autofocusing and silent, smooth autofocusing for video. Even in shooting situations with a shallow depth of field, quick, accurate focusing allows for beautiful defocusing effects by accurately focusing on faces and eyes when users select Face Detect AF or Eye Detect AF on Olympus OM-D and PEN camera bodies. When combined with compatible OM-D and PEN cameras’ Silent Mode, users are able to photograph musical performances and piano recitals without making a sound.

Limits comatic aberration to depict points clearly and accurately

This lens is capable of depicting points of light accurately, a necessary feature when photographing stars with the f1.2 aperture setting. Aspherical and high-resolution lenses placed near the aperture effectively correct for comatic aberration. These elements enable both the brightness of f1.2 and a high level of optical performance, making it possible to capture points of light without distortion.

Other Features:

• This lens features dustproof and splashproof construction, with hermetic sealing in 11 locations. When combined with the dustproof, splashproof, freezeproof body of the Olympus OM-D series, users can take advantage of all types of shooting environments.
• This lens boasts the same high-quality metal exterior design as the other lenses in the M.ZUIKO PRO series. It is equipped with the Manual Focus Clutch mechanism, which makes switching to manual focus possible by pulling the focusing ring toward you. A depth of field scale is included on the lens for pan focusing. And the L-Fn button on the lens barrel allows you to pause autofocus and assign other custom settings.
• Close-up performance is supported by a minimum focusing distance of 30 cm (working distance of 19.5 cm) and a maximum shooting magnification of 0.11x (35mm equivalent: 0.22x).

But this lens and you will never taste such things ever:

Look at the cats eyes - they literally ask you to go and buy old Minolta or Pentax lens instead.

At the risk of Vitaliy making fun of me for buying this overpriced lens...

Came in the mail yesterday, but haven't had a chance to get any real impressions yet due to dark, nasty weather. Can say this, though: Autofocus in photo mode (GH4) is one of the fastest and most accurate of any MFT lenses I've used. Autofocus in video mode is... well, pretty worthless. Hunts like crazy, sometimes never finding a subject, even in high contrast scenes. Standing a few meters from my dog, dog centered directly in frame, pressed and held focus button, watched the screen show a varyingly blurry dog for about 30 seconds before I just gave up.

I'll have a better idea of IQ in the next few days once my wife has a chance to have a go with it, then perhaps I'll have a Speedbooster Ultra and Sigma 18-35 for sale...
