为FS100“平反”又是一个英国测评人评FS100，对比F3(视频）

蹩脚翻译，接受拍砖！！

之前就有英国测评人Nigel Cooper把FS100贬的一文不值。今天这篇测评则是英国另一位自称自由摄影师、节目制作人Alister，他的测评结果是“与F3相当接近了”。他在xdcam-user开有博客，所以应该是个索尼派，所以测评的内容各位看官也要自己拿捏下哈。（Nigel Cooperc测评详见：http://107cine.com/zone/avccam/stream/906/）

The main aim of the shoot was to see how the FS100 held up against the F3. We shot on a bright sunny day by the River Thames and again in the evening in a typically lit living room. There were no big surprises. The FS100 is remarkably close to the F3. You would have no problems cutting between the two of them in a project.

Alister主要还是将FS100与F3做一个对比，他们选择了晴朗的一天，在泰晤士河边，还有一些室内照明场景。“没什么好吃惊的。FS100的确相当接近 F3。你把它们放在一个项目中剪辑完全没有问题。”

I did find that the FS100 LCD appeared less sharp and not quite as good as the F3′s even though they both use the same underlying panel. This is probably down to the additional layers required for touch screen operation on the FS100. I also did not like the 18-200mm f5.6 kit lens. There was too much lag in the focus and iris controls, but the beauty of this camera is that you can use a multitude of lenses. For the evening shoot I used a Nikon 50mm f1.8 which was so much nicer to use. On reviewing the footage I did find that we were tending to over expose the FS100 by half a stop to a stop, this does make making accurate comparisons difficult and I apologise for this. I believe this was down to the slightly different images we were seeing on the LCD’s. I did use the histograms on both cameras to try to ensure even exposure, but even so there is a difference. A small part of this is also likely down to the very slightly different contrast ranges of the two cameras.
首先他觉得FS100的液晶屏没有F3的好，但他们貌似使用的是同样材质的LCD，也许是因为FS100是触摸屏导致的。他不大喜欢18-200mm f5.6的套头，好像是有点对焦滞后。但FS100是可更换镜头系统，你懂得！晚上时使用尼康50mm f1.8效果就非常赞。在LCD里看到的图像差别并不大。他们有使用直方图控制曝光，但是即便如此还是有区别的。

One thing we discovered, not mentioned in the video is that when you use a full frame lens, like the Nikon 50mm. You must ensure that the E-Mount adapter you use has an internal baffle or choke. If it doesn’t you will suffer from excessive flare. The adapter I had did not have a baffle and some shots (not used) were spoilt by flare. The adapter I have from MTF for the F3 has a baffle as do MTF’s E-Mount adapters, so these should not suffer from this issue.
有一件事情影片中没有提到，如果使用全画幅镜头，像尼康50mm，就必须确保E卡口适配器中有baffle or choke。如果它没有你会遭受过多的光斑。

The FS100 performance is so very close to that of the F3′s (at 8 bit 4:2:0, 35Mb/s) that it is hard to tell the two apart. I believe the F3′s images are just a tiny bit richer, with about half a stop more dynamic range, in most cases it takes a direct side by side comparison to show up the differences.
FS100的表现非常接近F3(在8 bit 4:2:0, 35Mb/s情况下)，很难说出两者的差别。F3图像制式比较丰富些，需要并列比较才能看出差异。（见视频吧）

The range of camera settings and adjustments on the FS100 is not quite as extensive as on the F3, nor do the adjustments have such a broad range. However there is plenty of flexibility for most productions.
还有就是FS100的可调范围没有F3广。但是已经具有很强的灵活性了。

If you don’t need 10 bit 4:2:2 then it is hard to justify the additional cost of the F3, both cameras really are very good. Despite some other reports else where I felt the build quality to be very good and the buttons, while small, are big enough and well placed. If you do want autofocus then you will be pleased to know that it actually works pretty well on the FS100 with only minimal hunting (of course you must use an AF compatible lens).
如果你不需要10 bit 4:2:2，那就证明不了F3的额外意义。尽管有些别的测试结果说了些什么（此处直指Nigel Cooper的测评报告啊！！）但他还是觉得它的质量非常好，按键虽小但足够按了！

I did also record the HDMI output to one of my NanoFlashes at 100Mb/s. Comparing these side by side it is extremely hard to see any difference. It is only when you start to heavily grade the material that the advantage of the higher bit rate Nanoflash material becomes apparent. There is less mosquito noise in the NanoFlash material. I was really impressed by the AVCHD material. The lack of noise in the images really helps.

他们还使用HDMI外接记录到NanoFlashes上100Mb/s，还是难以看出区别。只有在Nanoflash更高bit的输出区别才会变得更加明显。AVCHD让他印象深刻，噪点控制的很好。

The FS100 really is the F3′s little brother. The pictures are remarkably close, which they should be as they share the same sensor. The FS100 packs down into a remarkably small size for transport. The loan camera from Sony was actually packed in a case designed for the MC1P mini-cam, about 15″x10″x5″ so very compact indeed. The F3 is considerably larger and bulkier, in part due to the extra space taken up by the built in ND filters.
SF100真的是F3的弟弟，图像相当接近，因为他们有着同样的传感器。SF100的体积很小，设计很紧凑。而F3就比较大了，显得笨重，还带了ND滤镜。
The lack of ND filters does need to be considered. There are some clever solutions in the pipelines from various manufacturers as well as existing solutions such as vari ND’s, screw on ND’s and a Matte Box with ND’s, so it’s not a deal breaker.
他觉得ND滤镜并不是那么重要。

I think there is every chance that the FS100 will be the first NXCAM camera that I will purchase. It will be a good companion to my F3. It’s modular design will allow me to get shots that are not possible with the F3. I felt that the FS100 (with the 18-200mm lens that I don’t like) was better suited to “run and gun” than my F3 with either manual DSLR lenses or PL glass. You can, with the FS100 simply point the camera at your subject and hit the one push auto focus and auto iris and have an in-focus, correctly exposed shot. This is much more like a traditional small sensor camcorder in this respect. The long zoom range also makes this more like a conventional camcorder, although there is no servo for the zoom.

他认为FS100于F3好的搭配。它的模块化设计能给他不同于F3的可能。他又一次嫌弃一下FS100的18-200mm镜头，他觉比起F3得适合“run and gun”（有没有高手说下这是神马）。

In conclusion, in my opinion, for “run and gun” or quick and dirty setups the FS100 with the 18-200mm lens has an edge over the F3 due to the fast auto focus and auto iris one-push controls. For more precise work and shallow DoF your going to want a different lens, something with manual control and calibrated focus and iris scales. For more demanding shoots then the F3 is probably the better choice with it’s slightly improved dynamic range and the ability to use S-Log and 4:4:4. In either case these cameras can produce highly cinematic pictures and I see no reason why you could not shoot a great looking feature with either.
反正他就总结了，F3外接了输出当然很无敌。“这两台机器都可以拍出非常电影的画面,你完全可以使用其中任何一台完成一个伟大的作品。”
