Image of Sony’s Curved Full-Frame Sensor Unveiled

by Barry Andersson5 Comments

I am very interested in what Sony is doing these days. I have been waiting for a camera company to close the gap with Canon in the DSLR/Mirrorless market.

The Sony A7s made a huge splash at NAB and I am eager to test it out soon.

What makes me intrigued most about Sony is their legacy of building high quality electronics. This announcement of their new curved sensor technology is super exciting. As with all new technology announcements we have to wait and see when it actually ships but here are the highlights:

– 1.4x increased sensitivity in the middle of the sensor
– 2x increased sensitivity in the corners
– Reduced noise from “Dark current”
– Ability for flatter lenses with wider apetures
– Already have a full frame sensor (as well as mobile phone versions)

First Image of Sony’s Revolutionary Curved Sensor Released, May Change Everything

Sony has officially released the very first image of what promises to be an impressive leap forward in digital imaging technology: the curved full-frame sensor.

Initially unveiled in April, Sony hasn’t taken any pains to keep this one a secret — and why should they? The process for making and stabilizing these curved sensors was developed entirely in-house, using machines Sony’s R&D department designed, and the company says it’s closer to mass manufacture than any previously-attempted curved array.

Sony’s Revolutionary Curved Sensor

With a curvature equivalent to that of the human eye, this sensor promises 1.4x better sensitivity in the middle and 2x better sensitivity in the corners! All of this while actually reducing noise caused by ‘dark current’ (which sounds like something out of Star Wars but is actually the current that is flowing through pixels even when they’re not receiving light).

  1. The curvature has nothing to do with the human eye. It’s likely present to compensate for field curvature.
    This compensation isn’t new. It goes back at least as far as the original Minox, and is likely even older than that. Lack of flatness got critical with the introduction of digital cameras. The pixels are so thin — thinner even than silver emulsion — that lenses have to have very flat fields to get a really sharp image. (I suspect this is one of the reasons “digital” lenses are bulkier.)
    The “catch” in creating a curved sensor array is that now you have to design lenses with the matching field curvature — or what would be the point. Then there’s the question of whether older lenses will now perform sub-optimally.
    I believe the preceding is correct. Someone set me straight if it’s wrong.

  2. William Sommerwerck Willian, there is no need to make new lenses, the curvature on the sensor will correct the problem of blur in the corners or less definition or soft focus in the edges of the images, and that is a well know problem in wide lenses and some tle lenses to; so we will have as result a sharper image edge to edge

  3. GerardoCampos William Sommerwerck  So you’re saying that the curvature compensates for the curvature of field in some existing lenses. Okay, that makes sense.
    But what about lenses that have relatively flat fields? Wouldn’t their corner performance be somewhat worse?

  4. William Sommerwerck GerardoCampos remember that most of the compensations are made by software inside the camera not in the lens; and for the flat lenses you have soft edges any way if you compare it with the center; so with this you will have the same sharness in the corners and edges than in the center

  5. GerardoCampos William Sommerwerck Then what is the point of the curved focal plane? The description said something about improved sensitivity, but it’s not clear to me how aiming the microlenses a bit better would result in a half-stop to one-stop improvement in sensitivity.
