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

(SR3) Did Zeiss just “leak” the Sony A7rII with 56 Megapixel sensor?
Dear SAR readers, take a look at that image:http://ift.tt/1ERne2q. Zeiss says it has been shot with the Sony A7r and the Batis 85mm lens. But notice two strange things:
1) The resolution of the image is 56 Megapixel
2) The 56MP images have no camera name exif info (had been removed by Zeiss).
Now we have three possibilities:
1) Zeiss up-sized the images for some weird reason I cannot understand.
2) This is a A7II multishift created image (feature that will may be added in a future update). But it’s unlikely to be used on non-architectural shooting and without tripod (reflection in the eye shows photographer handholding the cam!).
3) Or they did shoot those images with the A7rII and then removed the EXIF info. What’s your guess?
The new A7rII is rumored to be announced between mid May and early June at last. Stay tuned on SAR!
