变焦镜头

This eliminates the need to buy an anamorphic lens, but it introduces the nuisance factor of having to manually adjust the zoom lens and vertical picture height as well every time you change the format of the viewing material.

这消除了需要购买的变形镜头，但它引入了滋扰的因素，而不必手动调整变焦镜头和垂直图片高度以及每次改变格式的浏览材料。

The 1.5x zoom lens has enough range to move back and forth from 2.35 to 16:9 if the user wishes to set up a 2.35 CIH system with zoom changes rather than the anamorphic lens.

的1.5倍变焦镜头，有足够的范围，摆脱2.35来回16时09分，如果用户希望建立一个2.35 CIH病毒系统变焦的变化，而不是变形镜头。

This paper is the discussing about the aperture -coefficients of the Zoom Lens, the formula for the calculating is: F=f/d where.

该论文是探讨变焦镜头的光圈系数，镜头的光圈系数的计算公式：F=f/D(其中：F为光圈系数，f 为镜头焦距，D为光圈开口直径)。

This is very important in modern lens, the reflective glass surface decreased, so that there is more than a dozen pieces of the zoom lens on a reflective glass surface will be much less, so that the light through the lens will not be significantly reduced.

这在现代镜头上非常重要，玻璃表面的反光下降，这样在有十几片镜片的变焦镜头上的玻璃表面的反光就会少很多，这样通过镜头的光就不会明显减少。

The twin-lens kit gives first-time users loads of flexibility too, with an excellent Zuiko 14-45mm f/3.5-5.6 wide zoom lens and a Zuiko 40-150mm f/4.5-5.6 telephoto zoom lens.

双镜头套件，让第一次使用的用户负载的灵活性，也与一个很好的zuiko 14 -四十五毫米f/3.5-5.6广泛的变焦镜头和一个zuiko 40 - 150毫米f/4.5-5.6镜头的远摄变焦镜头。

Notice that a small amount of foreground focus can be gained by focusing the lens at a shorter distance than infinity known as Hyperfocal Focusing.

大多数定焦镜头在镜筒上都有超焦点刻表帮助调整最大的焦点。这就是为什么我们仍然不用变焦镜头而用定焦镜头的原因

This strong trans-standard Sony zoom lens offers a beautiful constant f/2.8 maximum aperture and an effective SAM fast autofocus technology for a reasonable investment. It also delivers sharp and well-corrected images in terms of distortion and vignetting. That means no post-production work would be necessary to improve the quality of images it produces

大意为，索尼这款镜头Trans-Standard变焦镜头拥有F/2.8的恒定光圈和非常高效的SAM高速自动对焦系统，他还有良好的在照片失真和抗眩晕方面的表现以及出色的照片锐度，TIPA认为使用这款索尼镜头拍摄的照片可以不必做很多后期的照片处理。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
