(SR5) Leaked: First image of the IRIX E-mount electronic adapter

Share

An anonymous source sent me this first image of the pre-fina IRIX E-mount adapter version (Thanks!). He told me this:

First image of the Irix original adapter for Sony. Infinity focus works, chip for focus confirmation too. And is wheater sealed.
Prices will be below $100.
Press release will be available in around a month.

The adapter is made to support Canon/Nikon IRIX lenses on E-mount cameras. I guess that you can use also original Canon/Nikon lenses on it.

IRIX lenses are currently on sale at Amazon US, Amazon DE, Amazon UK.

Some additional info on the five Sony medium format lenses for the Sony curved sensor camera

Share

Thanks to our more experienced readers we can share some additional info on the Sony patent describing a set of medium format camera lenses designed for a curved sensor:

1) The patent describes a broad use for this camera: “is applied to a telescope, a digital camera, etc.“. This is usual on patents because you want to cover as much areas of use as possible. An example is that on any camera patent Sony writes the camera could have a CCD or CMOS sensor even if all their new cameras keep using CMOS sensor only.
But that this is unlikely a pure astronomical camera is somehow proved by the fact that the patent also shows non-telephoto lenses which certainly are not ideal for industrial astronomy use (example is the 50mm FF equivalent lens which makes much more sense on classic photo cameras).

2) These are the five lenses patented for a 645 medium format camera with curved sensor. But first another important note: Sony Patents almost always have unusual focal length specs that will be rounded up once the lens gets produced (a 84mm lens will become 85mm or 258mm can become 250mm or 260mm). Also be aware that those are focal lengths on a 645 and not an FF camera. A 85mm lens is actually a 50mm lens (0.62 crop). So here are the patented lens specs:

  • 387mm f/2.8 (lens length: 679mm) – in Full Frame terms this is a 240mm f/1.7 (using online calculator)
  • 323mm f/2.8 (lens length: 576mm) – in Full Frame terms this is a 200mm f/1.7
  • 258mm f/2.8 (lens length: 380mm) – in Full Frame terms this is a 160mm f/1.7
  • 161mm f/2.8 – in Full Frame terms this is a 100mm f/1.7
  • 84mm f/2.9 (lens length: 123mm) – in Full Frame terms this is a 52mm f/1.7 (it would be 2cm longer than the Zeiss 50mm f/1.4 FE)

Mistral shared to use these drawings from the patent and added the lens specs info (Thanks):

What’s clear form the patent is:

  1. that these lenses do have a very simple design (thanks to the curved sensor)
  2. that they are big lenses but also very fast (f/1.7 FF equivalent)
  3. made for high Resolution sensors (thanksto their very high MTF)

No consumer available camera on the market so far could compete against this beast.

Oh yes Sony really patented this: First curved medium format sensor!

Share

Japanese patent “2017-102189” discloses a design of a new Sony 400mm f/2.8 medium format lens. Now that’s already an exciting news by itself. But there is more: The lens is designed for a curved medium format sensor. Some info from the patent:

  1. The lens is satisfying the effective image circle of 645 sizes, the single focus lens can be used as an interchangeable lens. (SAR note: 645 size is larger than sensors used on the Fuji GFX, Hasselblad X1D, Pentax 645Z, Leica S!!!)
  2. Thanks to the curved sensor design High MTF can be obtained.
  3. The patent clearly says that this camera applies for many different uses (industrial, astronomical and photography). That’s usual on a patent to describe as many areas of use as possible.
  4. The patent also shares the specs of some more medium format lenses:
    – 323mm f/2.8
    – 258mm f/2.8
    – 161mm f2.8
    – 84mm f/2.9
    Note: Patent almost always have unusual focal length specs that will be rounded up once the lens gets produced (a 84mm lens will become 85mm or 258 can become 250 or 260). Also be aware that those are focal lenghts on a 645 and not an FF camera. A 85mm lens is actually a 50mm lens (0.62 crop).

Now, before you get way too excited. Companies usually do patent all kind of stuff and only a small percentage of it becomes a real product.

That said this patent clearly proves Sony is at least thinking about the possibility of making a medium format mirrorless system camera with curved sensor. How much would this cost? Your kidney, your house or soul to Satan? :)
