The gigantic black hole in galaxy Messier 87 (M87) is the size of our solar system. The M87 black hole is actively creating a lengthy jet and emitting a radio wave signal that we are detecting some 55 million light years away.
In order to image this huge distant object, scientists created a virtual earth-sized telescope by combining signals from an array of 7 telescopes across the glove, and using the Earth’s rotation to scan the black hole.
5 PetaBytes of data was collected and processed to create the historic final 4K image: a fuzzy smile from a massive invisible black hole 55 million light years away.

Panavision has announced ULTRA VISTA a new series of large format anamorphic lenses, with a press release, and a striking vimeo demo. They are announced for release in 2019.
Some key features:

Image Size
– The Red Monstro 8K sensor is 8192 x 4320 pixels, and is 40.96 x 21.60 mm
– Ultra Vista lenses cover 7472 x 4320 pixels, which should be about 37mm wide.

2.76:1 Aspect Ratio
– Ultra Vista is designed for an ultra-long 2.76:1 aspect ratio
– This is of course the same ratio created by the classical Ultra Panavision System 70 lenses, that were recently used on “Hateful Eight” and “Rogue One”

1.6x Horizontal Squeeze
– Traditional anamorphic lenses have a 2x horizontal squeeze
– Vintage Ultra Panavision System 70 lenses have a 1.25x horizontal squeeze
– Ultra Vista lenses have a 1.6x horizontal squeeze, creating distinctive bokehs with a little more elliptical distorsion.

Large Format Anamorphic
The Ultra Vista lenses are great news for filmmakers. They offer large format anamorphic, with a bigger squeeze then traditional Ultra Panavision, and therefore more of an anamorphic feeling, and stretch the format to an ultra wide window on the world.
Theoretically the Ultra Vista lenses should also work on other Vistavision-sized sensors, like the Alexa LF and Sony Venice, with the possibility of different aspect ratios…

Bravo to my friends at Panavision for expanding the anamorphic palette !

Our friend Jon Fauer has posted a video shot by the folks at Servicevision in Barcelona, demonstrating their new anamorphic lenses. The footage shows the 35mm, 75mm and 100mm at T2 and T2.8, and was shot with an Alexa. (The AC, by the way, is very good at those wide open stops.)

The 35mm doesn’t appear to have much distorsion, and the lenses look clean wide open, but the thing that struck me the most were the bokehs, which were pleasing but more spherical than the ellipses I’m used to.

I look forward to seeing these lenses projected on a big screen.

I will be very interested to see the other lenses. Servicevision has announced a series of 14 lenses, ranging from 20mm to 300mm.

Panavision has introduced the Primo 70s, a new series of lenses designed for 70mm, but compatible with the Alexa, Dragon, F55 and Phantom 65.

I’ve had the opportunity to see them in projection and the quality is truly astounding.

The Primo 70s are made up of 11 Primes from 27mm to 250mm and 2 zooms
