Here are the six new next Sony Full Frame sensors with Quad Bayer Structure

Share

Sony has registered ssixe new Full Frame sensors. Below you can fidn the full spec sheets.What’s particular with those new sensors is that they have this Quad Bayer Structure. Sony writes:

HDR function is available by dividing exposure time in the 4 same color pixels into long exposure pixels and short exposure pixels. or dividing conversion gain in the 4 same color pixels into LCG pixels and HCG pixels.
Quad Bayer RAW function makes it possible to readout 4 same color pixels without addition.
When normal operation. 4 same color pixels are added and made 1 pixel, and output as bayer pixel array. In addition, a group of divided 4 same color pixels is defined as 1 pixel unit in this product specification.

Here are the short sensor specs:
IMX311: 48,9MP
IMX313: 48,9MP
IMX409: 55MP
IMX410: 24.6MP
IMX521: 15MP
IMX554: 30MP

Press Release: Aurora Aperture introduces a new filter system: adapter mount format filters for mirrorless mount adapters

Share

Aurora Aperture introduced a new filter system which you can preorder on Kickstarter (Click here).

Press Text:

Aurora Aperture introduces a revolutionary filter system: adapter mount format filters for mirrorless mount adapters

Irvine, California, July 15th, 2019 – Aurora Aperture Inc. today has introduced a revolutionary filter system, the Aurora Aperture Adapter Mount Format (AMF) filter for mirrorless mount adapters.

The AMF filters drop into mirrorless camera mount adapters such as the Canon Mount Adapter EF-EOS R, the Nikon FTZ, the Sigma MC-11 for Sony E, and the Sigma MC-21 for the L mount.

“In 2017 we introduced a rear mount filter system for the Canon EF 11-24mm F4L USM: The Aurora CR format, an industry-first rear mount glass filter,” said Jeff Chen, founder and CEO of Aurora Aperture Inc. “The Aurora Aperture CR format filters solves the problem of needing a huge filter adapter and massive filters for lenses that have protruding front elements. Due to the recent pivot of mirrorless camera development and releases from Canon, Nikon, Panasonic, Sony, and others: We’ve invented the Adapter Mount Format for the mirrorless mount adapters which enables mirrorless camera users to use a single set of filters for all their DSLR lenses regardless of the filter thread size.”

One Mount One Filter

Designed in California, the Aurora Aperture AMF drop-in filters offer many advantages over traditional front–mounted lens filters. Since a drop-in filter goes inside a mount adapter, users only need one set of filters per adapter instead of specific thread sizes for each lens. It not only saves users from having to buy multiple sets of filters or large diameter filters – but it also means awkward to use step-up rings are no longer necessary.

The drop-in filters are very compact and lightweight, meaning that they’re easily carried. They cost much less than traditional front mount filters, especially in comparison to large filter thread sizes.

Any DSLR lens that can be mounted on the four supported mirrorless mount adapters can be used with these drop-in filters, whether the lens has a front filter thread or not. This is especially beneficial for ultra wide-angle lenses without a front filter thread which would otherwise require massive filters on a bulky adapter.

Available Filters

  1. PowerUV™, a sensor protector filter to shield the camera sensor from contamination
  2. PowerND™, neutral density (ND) filters of light reduction strength in ND4 (2 stops), ND16 (4 stops), ND64 (6 stops), ND256 (8 stops), ND4000 (12 stops), and ND65000 (16 stops)
  3. PowerGND™, soft graduated neutral density (GND) filters of light reduction strength in ND3 (1.5 stops), ND6 (2.5 stops), and ND12 (3.5 stops)
  4. PowerDusk™, a light pollution reduction filter for astrophotography and for cityscape photography in blue hours by reducing artificial light pollution.

Schott B270® glass is used as the foundation of filters except for the PowerDusk which is based on neodymium glass. Multi-layer nano-coatings are used for light reduction so the filters are able to meet high-resolution demands of 4k/8k video and the high pixel density of modern-day sensors.

A PFPE based nano-coating is applied to both optical surfaces, ensuring the protection of filter against water, oil, dust, and dirt. This coating allows the filter to be easily cleaned as substances do not adhere as easily and are removed with little effort. The PFPE based nano coating has a 110-degree static contact angle, one of the best in the industry.

Aerospace-grade 7051 aluminum alloy is used for the filter frame. This material is practically twice as strong as 6000 series aluminum alloy used in conventional lens filters.

Availability and Pricing

The AMF Filters will be available through a kickstarter.com crowdfunding campaign starting in July 2019. The general public and dealer availability starts in October 2019. The price will start from $44 and goes up to $83 per filter, depending on the type of filter.
