只买机身,然后另外购买一个高速镜头.(译者:一般指允许进光更多而提高快门速度的,大光圈镜头。
它的大光圈镜头可以摄入尽可能大的光量,所用技术并不需要笨重的自动对焦系统,曝光时间也是自动调节。
It has a wide-aperture lens to capture as much light as possible, and the technology requires no clunky auto-focus mechanism. It adjusts exposure time automatically.
很多时候被误解为对焦快的镜头-_-我个人喜欢佳能50毫米定焦1.4光圈或者1.8光圈镜头。尼康也有相同型号标准高速镜头可以在室内或低光条件拍摄时,提供高品质的图像。
I like the Canon 50mm 1.4 or 1.8 (I'm sure there is a comparable Nikon) a faster standard lens will allow you to take great food shots when you are indoors or when less light is available.
一些卡片机目前已经支持如f2.8的光圈镜头,这个已经勉强应对。同时有些卡片机目前可以装载f/2.0甚至f/1.8的镜头,这些镜头排出相片的质感实在是棒极了。
Several compact cameras now have lenses with apertures of f/2.8, which is not bad, and there are even a few that are as fast as f/2.0 or even f/1.8, which is great.
最简单的办法是选用最小的光圈设定(镜头上显示的最大的数字),光圈越小,你所获得照片的景深就会越大。
The simplest way to do this is to choose a small Aperture setting (a large number) as the smaller your aperture the greater the depth of field in your shots.
主要镜头是固定的,没有自动对焦和自动光圈以及其他小配件。
The main lens is fixed in place; there is no auto-focus, auto-aperture, or other gubbins.
问题在于要用镜头上的光圈盖住传感器芯片。
The problem is covering a rectangular sensor chip with a circle of light from the lens.
你设置光圈(用于指定有多少光进入照相机镜头)——你想照一幅漂亮、浅景深或广角的照片吗?
You set the aperture, which dictates how much light comes into the camera-do you want a nice, shallow depth-of-the-field, or everything in focus?
即便你打算使用小光圈照相,带有最大光圈的镜头也可以在取景时大大增加取景器亮度。
Even if you intend to expose using a small aperture, a lens with a large maximum aperture can greatly increase viewfinder brightness.
f制光圈(或称光圈)决定相机的景深(对焦区域)以及有多少光能通过镜头到达传感器。
The f-stop, otherwise known as the aperture, determines your depth of field (the area in focus) and how much light can pass through the lens to reach the sensor.
实际上,当你按下快门时,一套复杂的程序开启,包括镜头内光圈的设置、一块单镜头反射镜的升起和其他更多的步骤。
When you press the shutter release on the camera, a complex sequence of events occurs, including setting the aperture in the lens, flipping up the mirror of an SLR and a lot more.
当你继续研究比较昂贵的变焦镜头时,你会发现它们有着恒定的光圈。
As you move onto the more expensive zoom lenses, they maintain a constant aperture.
一般的解决方法就是用比镜头最大光圈小一些的光圈值,然后用屏幕预览,放大,确认每个人看上去都挺好。
The solution is often to shoot a few clicks smaller than the lenses widest aperture, then use the preview screen and zoom button on your camera to make sure everyone is looking good.
基本上,光圈在1.8左右的镜头已经足够大多数人使用了,并且时常你还要把光圈调小了使用。
In general, all you really need is one that is around F1.8 as that aperture is wide enough for most uses and you may even find yourself closing that up at times.
就像镜头有一个光圈范围,你的相机也有一个快门速度的范围。
Just like a lens has a range of apertures, your camera has a range of shutter speeds.
然而像我们这些单反相机的使用者在有足够多的经验之前,总是很难理解一个大光圈的50mm镜头是多么的实用。
What some of us DSLR users don't realize until we've grown enough is just how wondrous and useful a good 50mm lens with a wide aperture is.
远摄镜头的性能加上f/2.8的光圈,再加上最长500mm的长焦端,使该镜头适合拍摄野生动物和体育赛事,也是天文爱好者进行天文摄影的绝佳镜头。
The combination of telephoto capabilities and an f/2.8 aperture throughout the zoom range up to 500mm makes this a great lens for wildlife, sports and for you stargazers, astrophotography.
即是镜头光圈与影像平面之间的距离。
It is the distance between the lens diaphragm and the image plane.
50mm定焦镜头在较大价格范围内的平均光圈是F1.4,便宜的(镜头)光圈为F1.8,较贵的(镜头)光圈为F1.2。
The 50mm prime on average allows an aperture around F1.4 on a mid ranged price lens, F1.8 on the cheaper ones and F1.2 on the pro series.
光圈就是镜头里面的一个小洞,就是一块横膈膜一样的东西,好让光线穿过。
The aperture refers to the hole in the lens, known as the diaphragm, that lets the light in.
光圈f/1.8的镜头和光圈f/5.6的镜头之间的区别可能相当于一张以400感光度拍摄于黄昏的清晰教堂照片和一张以3200感光度拍摄的模糊影像之间的区别。
The difference between an f/1.8 lens and an f/5.6 lens can be the difference between a clean picture of a church at dusk shot at ISO 400 or a grainy image shot at ISO 3200.
光圈调至f32-这是镜头上的最小光圈。
Set aperture to f32 - this was the smallest I could get on the lens.
光圈调至f32-这是镜头上的最小光圈。
Set aperture to f32 - this was the smallest I could get on the lens.
