Samyang has announced a bunch of mirrorless lenses, as well as a 10mm f/2.8 ED AS NCS CS Lens for Canon.</p>
<p><strong>Product Overview</strong>

The Canon EF mount Samyang 10mm f/2.8 ED AS NCS CS Lens is a prime, manual focus wide-angle lens designed specifically for use with APS-C-sized image sensors. Providing a 35mm-equivalent focal length of 16mm and a broad 105.9° angle of view, this lens is ideally suited for interior, architectural, and landscape photography applications. One extra-low dispersion element and two aspherical elements have been incorporated into the optical design to minimize chromatic aberrations and distortion in order to produce sharper images. Additionally, a nano crystal anti-reflection coating system (NCS) has been applied to lens elements in order to reduce surface reflections and prevent lens flare and ghosting for improved light transmission and more contrast-rich imagery.</p>
<p>The price of the lens is $529 USD and will be available on March 25, 2014.</p>

<p>Press release after the break…</p>

<p><strong>From Samyang: </strong>The prototype version of the Samyang 10mm f/2.8 was first presented at Photokina 2012. Since then, intensive work to improve the lens and to achieve the highest possible optical quality while reducing its footprint. The result of this work is presented today lens Samyang 10mm 1:2.8 ED AS NCS CS, which in terms of performance and capabilities can successfully compete with the best wide-angle designs available on the market.</p>
<p>Samyang 10mm 1:2.8 ED AS NCS CS is a great tool to photograph interiors, architecture and landscapes. It offers an exceptionally wide field of view, ranging 109.5 degree and linear imaging performance. It features a wide f/2.8 aperture for shooting in low light conditions. It can therefore be successfully used in sports photography and reportage. The optical design of the lens consists of 14 elements divided into 10 groups, which include 2 AS aspherical lenses and one ED glass with a very low coefficient of dispersion. Also, the lens has gained a permanent hood to allow for its compact dimensions and to reduce weight by almost 160 grams from the prototype stage.</p>
<p>Samyang 10mm 1:2.8 ED AS NCS CS is the first lens produced by Samyang Optics, which uses nano-crystalline anti-reflective coating. It is characterized by lower reflectance than the shell (U) MC, and the process of applying for a better fit to the structure of the lens surface. The benefits of using nanocrystalline coatings are: much better light transmission, greater resistance to glare and higher contrast, which positively affects the optical resolution of the lens.</p>

For all those who have been asking for a UWA prime lens specifically designed for APSC, here it is ... but the price is not competitive for a manual lens, I guess it might come down in a few months.

If this is designed for APS-C-sized image sensors, wouldn't this be an EF-S mount? Or this would still fit an EF mount and just not take up the entire sensor? Anyhow, it's pretty expensive for a specialty lens. I agree that the price will go down.

Samyang 10mm is designed for APS-C cameras, but it fits and works on full frame cameras, with the corners of the black image because of the size of the rear lens element. The "EF-S" nomenclature is exclusive original Canon lenses, and they purposely did not fit full frame cameras.

Meh.....

Over $500 for a manual focus lens that is only 1/2 stop faster than a similar priced zoom that is already well regarded. I expect to see the street price around $250-300 if they actually want to sell any. Crop users are usually less likely to use primes so the price had better be attractive.

The 14mm UWA was great because it was wider than the canon zooms available.

$500 for a 10mm f2.8 manual focus prime vs. OEM 11mm f4.0 AF zoom IS with a street price of ~$450 :-\

Assuming optically the prime is very good, I still don't understand why anyone would pick up the RokiBowYang, even at a discounted street price of say $350. I own a few of these Korean made lenses and while sharpness peaks like crazy in the mid range apertures, much is left to be desired up to 2 stops from wide open.

The Tokina f2.8 zoom is just as fast, about the same price, has autofocus, also fits a full frame and is equally well-regarded as well. So, I agree with you:

oops, i realize not everyone cares to shoot with the M. it's technically not EF-S compatible :)
