Latest Rumors on SonyAlphaRumors.com [twitter]( [facebook]( Sony α7C II is NOT coming in 2022, but three (or maybe four) other new Sony cameras will be announced A rumor posted by a website that never got a single rumor right is going around the web. It says the A7cII is coming this fall. Well, according to what I have learned so far the A7cII should not be on market in 2022. There will be three (and maybe four) new Sony cameras that will be announced during second half of 2022. More about it here ([subscribe the Youtube channel!]( [Read more]( RUMOR: The new Sony 24-70mm f/2.8 GM II will be announced in April I can now confirm with 99,999% certainty the new Sony 24-70mm f/2.8 GM II will be announced in April. No info on pricing yet. One of the three sources that told me about this lens sent me the following info: This will come out in April, and the size, weight, and volume have decreased. The image quality is similar. [Read more]( The big Sony medium format system talk: 53.5mmx40mm sensor with 150 and 200mp, lots of f/1.7 primes and very expensive! Before we get into this speculative bit about the Sony medium format system I kindly invite you to subscribe [my new Youtube channel (click here)](. And now let's get onto it: - It's about time to talk about facts, myths and rumors about the possible future Sony medium format system. In my video above I explain everything we know so far and below you can find some facts and rumors. It's important to disclose ASAP that there is no hard fact yet that convinced me the medium format system is coming any time soon. But there is some increasing background noise, and some patents that gives us some breadcrumps on how such a system might look like: Sony statements on Medium Format: Back in 2017 Sony manager said that at least for now they rule out the possibility to launch a medium format camera. The reason is that it takes a lot of time and resources to develop a new system with cameras, lenses and accessories. At the same time Sony they have all the necessary resources (knowledge and components) to make such a medium format camera if they would like to do it. One image: [Fuji GFX100s]( [Mamiya 7II]( and [Sony A7rIV]( But since 2017 may new patents have been published by Sony and here is a quick roundup: Here is one of the many [Sony f/2.8 medium format lens patents](. In detail we got this: - 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]( The extraordinary feature of those lens patents is that they are all designed for curved sensors. Sony patented some curved sensors design ([example here](. This includes also Full Frame curved sensors ([example here](. Some other company like for example CEA-LETI already displayed some working prototype ([more about this here](. While Sony already showed an image sample shot on a curved sensor back in 2014 ([see here](. [VLSI Symposia tipsheet]( (via [ISW]( explained better how this sensor works: “Curved CMOS Image System: When light transmitted by a lens strikes a perpendicular target such as a CMOS image sensor, it forms a circle of light called an image circle. It’s difficult for a flat (planar) CMOS image sensor to deliver high image sensitivity at high resolution (highly scaled pixel pitch) because of the fundamental physical limit known as quantum efficiency. To break through that physical limit and to achieve higher sensitivity anywhere within the image circle at higher resolution, Sony built and will describe an imaging system that comprises a hemispherically curved, back-illuminated CMOS image sensor (BIS) and integrated lens. It doubles the sensitivity at the edge of the image circle while increasing sensitivity at its center by a factor of 1.4, with a 5x reduction of dark current (Jd) compared to a planar BIS. Moreover, a common problem known as lens field curvature aberration (Afc) is mitigated by the curved sensor itself, and so the curved BIS enables higher system sensitivity with a brighter lens with a smaller F number (Fn) than is possible with a planar BIS. In addition, by controlling the tensile stress of the BIS chip to produce a curved shape in the first place, the energy band-gap (Eg) is widened and a lower Jd is achieved. (Paper T2.1, “A Novel Curved CMOS Image Sensor Integrated with Imaging System,” K. Itonaga et al., Sony)“ Recent medium format Rumors: The only rumor I got from solid sources says that Sony is working on a new kind of camera. But we shouldn't get too excited about that wording. It could mean a new kind FF camera too. All other rumors are from anonymous sources and therefore at high risk of being B.S. The last two I got tell us this: [Posted on SAR]( on December 13: Simultaneous announcement about curved sensor medium format camera development (2 cameras, 150mp and 200mp, 9-12 prime lenses, very expensive, to follow quickly) [Posted on SAR]( on December 13: the medium format system Sony will release in 2 years has not curved sensor, its a new developed 200mp 54×36 sensor in a new mount, Sony will release an adapter to use E lenses (just they can say it had a lot of compatibility lenses cause the system will be released with only 3 primes) and will be a system without mechanical shutter with flash sync faster than anything in the market by far, its a system targeted for ultimate studio work The business case for a Sony medium format system: The [Sony A1]( and the [Fuji GFX]( proved that people is willing to pay a lot of money for exciting cameras. In all those years of constant camera market decline only the high end stuff keeps selling. Sony might have been motivated to be bold and launch a MF system. Wrap Up: If patents are any indication for the direction Sony wants to go with their medium format system than we can assume this: -  The sensor is 2.2x larger than FF with 53.5mmx 40mm size and 0,65 crop factor. This is larger than the current Fuji GFX sensor (44x30mm, 1.7 larger than FF and 0,79 crop) - All these sensors are curved. This allows the lenses to be much smaller because they don't need additional glass to correct for distortion. And it allows to get the same sharpness all across the frame. The f/2.8 (FF equivalent f/1.7) lenses are barely larger than Full frame f/1.4 primes. - The patented lenses are all primes with f/2.8 aperture. This is equivalent to f/1.7 in Full Frame terms. So you see, Sony seems to aim for a proper 645 sensor with curved sensor tech to beat the Fuji GFX system in terms of image quality while still maintaining a relatively compact lens system. The trade off is that such curved sensors are eventually going to be very costly to produce. It's all speculation for now, and patents are no proof for real stuff happening. But I hope that within the next few months we will finally learn more if Sony is serious about this. Maybe after reading this known sources can give me some more info about what's going on with Sony's medium format plan ;) Make sure to subscribe my new [Youtube channel]( to follow me on [Twitter]( [Instagram]( and on [Facebook](.
