Kipon将推出f/0.85大光圈镜头 售价2000美元金色的脚印作业金蝉脱壳课文注音本学期我读过的课外书

新华网12月16日电 据美国科技博客Gizmodo报道，今年大家见过很多大光圈镜头，比如Sigma 18-35mm f/1.8和Metabones Speed Boosters。但是明年你还能看到一款40毫米f/0.85光圈镜头。

Kipon这家不太知名的摄影器材制造商将在明年2月推出Ibelux 40毫米 f/0.85镜头，届时将有Sony NEX、Fuji X、Canon EOS M和Micro 4/3接口。看起来这款镜头不能覆盖全画幅传感器，而且价钱竟然达到2000美元。

43rumors.com网站说有一款莱卡65毫米镜头达到了f/0.75光圈，因此Ibelux自称“世界上最快的镜头”不完全对，不过仍然确实非常惊人。

给镜头小白们解释一下，光圈越大镜头进光量越大，在黑暗的环境下照片也会更亮。大光圈一般在f/1.2左右，f/0.85光圈的缺点是在广角端锐度会下降。而Kipon作为不太知名的品牌，镜头成像素质就很难说了。以下是Kipon网站上提供的图片：

The Crazy Huge Aperture on This New Lens Chews Up Darkness

It\'s been a good year for really huge aperture sizes on camera lenses, with products like the Sigma 18-35mm f/1.8, and the Metabones Speed Boosters. But next year you\'ll be able to get your hands on a 40mm lens with an aperture size of f/0.85. That is one gaping piehole.

The Ibelux 40mm f/0.85 comes from Kipon, a lesser-known maker of photographic accessories. It will drop in February 2014 and be available for Sony NEX, Fuji X, Canon EOS M and Micro 4/3 mounts. It doesn\'t look like it will cover full-frame sensors, however. The price is a whopping $2000.

43rumors.com points out that there is actually a Leica 65mm lens that features a f/0.75 aperture, so the Ibelux\'s "fastest lens in the world" claim isn\'t completely accurate. It\'s still damn impressive though.

For the non-camera-nerds out there, the bigger the aperture, the more light a lens lets in, and the brighter your pictures can be in dark settings. Aperture size usually tops out at f/1.2 or so. The trade-off with a huge size like f/0.85 is that sharpness will likely suffer when shooting wide open, and with a relatively unknown brand like Kipon, it\'s hard to say what the overall quality will be. Here are some sample shots from the Kipon website:
