Samyang releases the E-mount 10mm T3.1 and 12mm T2.2 Cine lenses and the 300mm Mirror for A-mount

Samyang announced two new E-mount and one new A-mount lens. Full specs can be read by clicking those links:
Specification – Samyang 10mm T3.1 Cine E-mount (specs here)
Specification – Samyang 12mm T2.2 Cine E-mount (specs here)
Samyang 300mm f/6.3 Mirror UMC CS A-mount (specs here)

Here is the official Samyang press text:

10 and 12mm E-mount:
Nearly a month after their market release, Samyang 10mm f/2.8 ED AS NCS CS and Samyang 12 mm f/2.0 NCS CS lenses are now available in their equivalent cine versions: Samyang 10mm T3.1 Cine and 12mm T2.2 Cine. Samyang VDSLR cine lenses feature aperture and focus rings with sprocket wheels controlling their work through Follow Focus systems. This allows for noiseless and smooth adjustment of the above parameters during filming.
Samyang 10mm T3.1 Cine and 12mm T2.2 Cine have nanocrystal anti-reflective layer (NCS) that ensures better light transmission, increased resistance to light reflections and higher contrast, which improves optical resolution of the lenses.
Samyang 12 mm in photo and cine versions fills the gap among lenses dedicated for mirrorless cameras with APS-C sensor, large angle of view and high brightness. The lens has been designed for cameras fitted with a high resolution sensor (above 24 mln pixels). Samyang Optics company is renowned among clients for great quality optics offered at affordable prices. And this is also the case with 10mm and 12 lenses which provide technical parameters and optical potential that can easily compete with the best wide-angle prime and zoom lenses available on the market.

300mm A-mount:
Samyang offers light and compact 300mm f/6.3 Mirror UMC CS mirror lens in DSLR version with Canon EF, Nikon F, Sony A and Micro 4/3 mounts. Optical construction includes 8 lens elements arranged in 8 groups. The lens elements have been covered with anti-reflective, multi-layer (UMC) coatings of new generation to minimize light reflections and increase contrast. Owing to large focal length, really affordable price and small sizes (the lens weighs only 260g), your lens will become inseparable companion for all reflex camera users in “the field”.

New 250mm f/4.5 APS-C E-mount Mirror lens patent

Sony published a new patent for a Mirror lens having a focal length of 250mm and f/4.5 aperture. It’s designed for APS-C E-mount cameras. A perfect lens to spy the neighbourhood take pictures of birds :)

By the way, if you are looking for an E-mount mirror lens you can also buy that Albinar 300mm on Amazon US (Click here) or [shoplink 26152 ebay]eBay (Click here)[/shoplink].

(SR5) Sony announcement on April 30-May 1 with “surprises”

Sony keeps making me work all days on rumors including Saturday and Sunday :)

Right now I am chatting with sources and they confirm Sony has a “BIG” announcement next week on Thursday April 30 (London time). And there will be more than just the A77II. And there is a big chance to see some surprise(s). So please stay tuned on SAR the coming hours and days!!!

Sony is very very very serious about the curved sensor tech! New official announcements.

Sony sensor tech. Image source: VLSI Symposia tipsheet

A couple of weeks ago I showed you two patents describing a Full Frame curved sensor and a 35mm f/1.8 lens designed for such a sensor. Usually when you see Sony patents you well know that it could take ages to see it applied on a real world mass product. Well this could be one of the few cases where a patent becomes “real” in a very short time.

First of all the prestigious site Nikkei Japan reports that Sony has developed a curved sensor that doubles the sensor sensitivity. And Nikkei doesn’t spread a news based on patent :) It means Sony is really ready to launch that kind of tech!

And than 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)“

And as you know an anonymous source said the RX2 with curved sensor tech and 35mm f/1.8 lens will be announced in summer. it has to be seen if Sony can use such a curved sensor on an interchangeable E-mount camera…

Mitakon 50mm f/0.95 Full Frame E-mount officially announced.

The Mitakon 50mm f/0.95 FE lens has been officially announced (Source: Mxcamera). It will be available soon on eBay MXcamera. And you can save that search on Slidoo to get notified when it’s in Stock. This is Mitakons second E-mount lens after the [shoplink 14656 ebay]35mm f/0.95 lens for ASP-C E-mount cameras (they are on auction here on eBay)[/shoplink]

And Steve Huff got the number 00001 of the lens in an extremely nice package which is included in the $799 price. This could become a real hot seller if the Image quality wide open is acceptable.

The lens will ship in May and these are the specs:
Lens mount: Sony FE
Focal length: 50mm
Optics: 10 Elements (7 groups)
Image cover: 35mm full frame
Max. Aperture: f/0.95
Min. Aperture: f/16
Filter size: 58mm
Lens size: 87mm (L) x 68.5mm (diameter)
