Did you know that ZEISS products are orbiting a comet?

When the Rosetta probe was sent on her ten-year journey through space to the Churyumov–Gerasimenko comet, there were amongst others two spectrometer systems featuring ZEISS gratings on board. Thanks to the landing of the Philae minilab and the measurement data sent to Earth, the Rosetta Mission is highly successful and you can view stunning pictures made by the probe.

Impressive! New Batis 85mm almost matches the Otus 85mm performance!

So, what’s the optical performance difference between the $4,490 85mm f/1.4 Zeiss Otus and the $1,199 85mm f/1.8 Zeiss Batis? Almost none! Just check out the comparison between the two MTF graph (Click to enlarge).

While the MTF performance is very close the Zeiss Otus still has the advantage of being faster (f/1.4 vs f/1.8) and it has less distortion. See the MTF and Distortion files here:
Zeiss Otus at Zeiss.de
Zeiss Batis at Diglloyd.

As our reader Seeky stated it relly looks like the 85mm Batis is a sort of mini-Otus!

Both lenses are now available for preorder in USA and Europe (UK/Germany)

DxOmark tests the new Sony 28mm FE lens- Says it’s a “Wide-angle prime with top results”!

Dxo_28mm_fe_sony

DxOmark (Click here) just published the Zeiss 28mm FE lens results and writes:

Ranking third for all hybrid lenses, just behind two significantly more expensive Carl Zeiss options, is a great result for the Sony FE 28mm F2 lens. At a cost of just $498, and boasting a “fast” F2 aperture and solid results in most categories, it’s an affordable wide-angle solution for Sony A7 series shooters. It’s actually marginally ahead of the Zeiss wide-angle competition overall for sharpness, but isn’t quite as strong at F2.8, where the corners drop off a little. The main area of concern is Distortion, however, with quite heavy “barrelling” that landscape and architecture photographers will want to correct in post-production.

An absolute great performance for the money!
The FE 28mm is now in Stock for the first time in USA at Focuscamera eBay (Click here).

Zeiss Distagon second best lens after the 55mm FE:
It’s also interesting to note that DxO also added the Zeiss FE 35mm f/1.4 to the database. With 38 points it scores as second best FE lens right behind the 42 points of the 55mm FE lens.
The 35mm Distagon is finally in back in Stock at Amazon US (Click here).

#tbt - ZEISS completed the development of the first projector for planetariums in August 1923 – enabling a projection planetarium's representation of the artificial night sky to be observed for the first time at the ZEISS facilities in Jena. The ZEISS projector was then brought to the Deutsche Museum, where it provided lifelike representations of cosmic happenings and planetary movements until 1960.

Diglloyd posts the full Batis MTF graphs. “(85mm Batis) Has outstanding micro contrast no less good than the very best Leica M lens”

Zeiss_Batis_mtf_graph

Quick note for Germans: Since today you can preorder the Batis lenses at Amazon: 85mm (Click here) and 25mm (Click here).

Digglloyd is the first site publishing the full graph of the new Batis lenses! Links:
Batis 85mm MTF at Diggloyd.
Batis 25mm MTF at Diggloyd.

Here are some of his early conclusions:

BATIS 85mm:
- Overall contrast is superb wide open, even into the corners.
– Stopping down a bit more delivers outstanding micro contrast at f/5.6, far exceeding most lenses and no less good than the very best Leica M lens.
Has some pincushion distortion. Seems that distortion was traded off for uniformly high sharpness and a smaller/lighter design, knowing that the camera can correct for it automatically (or the raw converter).

BATIS 25mm:
- Modest micro contrast at f/2. However, overall contrast is superb wide open, even into the corners, and that very high overall contrast is critical to visual impact of the image.
– Most notable, the performance is exceptionally uniform at all apertures from center to corner. This is highly unusual for a 25mm lens.
