Crystallography rocks! #1



In this picture, what looks like an abstract painting is actually graphite and feldspar in an ultra-high temperature granulite from the Kerala Khondalite Belt in India. Not only is feldspar beautiful, it is also the main rock-forming mineral in the Earth's crust.



2014 is the international year of crystallography (www.iycr2014.org). In the micROCKScopica series, we will show you a series of wonderful microscope images by Bernardo Cesare, Professor of Petrology in the Department of Geosciences of the University of Padova, Italy.

(SR4) Fast 85mm FE lens prime is on roadmap (to be disclosed at Photokina).

A FAKE rendering of a possible Sony 85mm f/1.8 FE lens (Source: Xitek.).

According to one source Sony will disclose a new FE lens roadmap right before Photokina. And he said there will be certainly a fast 85mm prime. He didn’t unveil specs and pricing info about the lens. Very unreliable rumor floating around the web say this could be a Zeiss 85mm f/1.8 lens. One thing is sure: Sony FE lens designer Naoki Miyagawa said he is “dreaming” about an ultra fast 85mm FE lens (Source: Lesnumeriques -google translation here).

The new Laser Scanning Microscope ZEISS LSM 880 with Airyscan



With Airyscan, our colleagues from ZEISS Microscopy just introduced a new confocal technology, which offers a new dimension of fast and sensitive superresolution microscopy. Instead of detecting signals with a single point detector and rejecting out-of-focus emission light at the pinhole, a multichannel area detector with 32 elements collects all the light from an Airy disk simultaneously. Hereby, each detector element functions as a single, very small pinhole.



Knowing the beam path and the spatial distribution of each Airy disk enables very light-efficient imaging: researchers can now use all of the photons that the objective collected. Visit www.zeiss.com/lsm880 to learn all details.
