首先要说的是咱我抱歉自己的购买取向和摄影器材进价影响到你的进价考虑，

但是，

现在很多二手可以使用的定焦大炮类镜头也便宜了很多（不用像我那样花6万元多去买佳能新的640的二代大炮），

佳能可以使用的600mm第一代防抖镜头3万以内元可以拿到的，

还有就是副厂佳能口的适马镜头，

二手适马的300-800的变焦大炮镜头一般都不超过2万元，

只是我很不屑使用副厂镜头（个人经历已经是被固化的思维），

我是先确定了哪种接环，

买入接环去试各种镜头，

合适就购入爽爽的拍摄。

你看看蜂鸟、鸟网的二手交易信息（最后面有截图）：

可以使用的到400焦段的变焦镜头可以关注：

1、索尼70-400G的1、2代（厂家说差别仅仅是对焦速度）镜头，使用索尼三代转接环或者四代转接环，三代可以使用更先进的CMOS嵌入399点相位对焦。

2、佳能100-400的1、2代（厂家说画质差别很大）镜头，也包括佳能口的适马、腾龙等厂家的150-600这类镜头，使用第三方转接环。

3、尼康80-400的1、2代（厂家说画质差别很大）镜头和200-500镜头，也包括尼康口的适马、腾龙等厂家的150-600这类镜头，使用第三方转接环。

4、其他厂家的各种卡口可以到400焦段的变焦镜头，这些卡口的转接环都没有实现自动对焦功能。

5、还可以等待索尼原厂的E口超长焦镜头，也可以等待佳能的200-600镜头。

6、我自己只会首选索尼的转接，然后是佳能的转接，尼康的和其他厂家的暂不考虑是因为转接环的不成熟和稳定。

没有看到有人说A7R II使用MB4转接环不支持转接佳能的大炮，

我自己实际转接的一些佳能最新的大炮也没有遇到问题（除了456对焦很慢以外，现在的最新大炮都没有遇到对焦快慢的问题），

看我首页说过的话的截图和国外测试300定焦的评语。

国外评测评语：

Canon EF 300mm f/2.8L IS II USM Lens
Metabones: Fast and accurate PDAF AF-C and AF-S with Wide, Center and Flexible Spot
Fotodiox: Fast and accurate PDAF AF-C and AF-S with Wide, Center and Flexible Spot
Viltrox: Fast and accurate PDAF AF-C and AF-S with Wide, Center and Flexible Spot
NOTES: Image Stabilization functions best with Metabones (with fw 0.41) on a7RII.

Canon EF 300mm f/2.8L USM Lens (version 1)
Metabones: HUGE SURPRISE! Good Speed PDAF AF-C and AF-S is possible!!! Whoa!!!
Fotodiox: Manual Focus only – but adapter provides electronic aperture control
Viltrox: Manual Focus only – but adapter provides electronic aperture control

Canon EF 300mm f/4L IS USM Lens

基本摄影器材的常识要知道：

索尼和佳能机身的法兰距、口径不一样怎么直接互换插入各自的镜头，

绝大多数的厂家的机身法兰距和口径都不一样，

所以直接互换镜头是天方夜谭的事情，

但是短法兰距的机身可以使用转接环转接长法兰距的厂家镜头。

索尼可以使用的能自动对焦的转接环（佳能镜头转接到索尼机身的转接环）有几种，

下面就是国外对索尼转接佳能原厂镜头和佳能口的适马、腾龙、图丽镜头自动对焦测试效果列表的链接（也可以看本帖的6、7楼），

柯达的全画幅单反早就世界范围和国内销售过啦（使用的尼康的镜头），

记得那时的价格是4.7万元人民币，

比佳能的6.5万人民币的全画幅1Ds便宜。 本帖最后由 花冠摄影 于 2016-1-24 09:52 编辑

UPDATE: When I tested the next two recently announced Tamron lenses I was a bit disappointed with AF performance – particularly on the SP 45mm at close distances. But Tamron rep Marc Morris tells me “Because VC pulls needed power from the adaptor, the trick is to switch VC off and let the a7RII SteadyShot work. Once VC is off, AF performance is great.”

While I don’t have the lenses available to re-test, Marc never steered me wrong.

The Bottom Line
Canon Smart Adapter AF performance was greatly improved with a7RII compared to previous Sony E-mount cameras. Overall AF performance was fairly comparable, yet each of theses three adapters performed slightly better with certain lenses . The $100 adapters from Fotodiox and Viltrox look identical and while the results are close, but I have grown to prefer Fotodiox because it has better build quality. I had to tighten the lens mount screws on the Viltrox repeatedly over the course of testing.

As I said in the introduction, Metabones Smart Adapter IV with Firmware 0.41 is the only adapter that allows you to use the lens IS switch to choose between using lens-based optical Image Stabilization and Sony a7II/a7RII IBIS. Firmware on the Fotodiox and Viltrox adapters is not user-updatable.

Because of this I recommend that anyone who plans to use Canon IS lenses on Sony a7II or a7RII cameras stick to Metabones. But if you never plan to use Canon IS lenses on Sony IBIS cameras such as a7II and a7RII you can save yourself a few hundred dollars with Fotodiox or Viltrox.

《SONY A7RII CANON EF SMART ADAPTER TESTS》

Earlier this summer I posted my Canon EF Smart Adapter Guide for Sony E-Mount Cameras for Sony a7, a7R, a7S, a7II, a6000, a5100, a5000 and NEX mirrorless cameras, but Sony a7RII‘s 399-point PDAF and 25-pont Contrast AF system completely changes the game.

So last week I jumped on a plane and headed to B&H Photo for two days to test every Canon EF lens I could get my hands on. Here are my updated tests for the Sony a7RII using these Canon smart adapters:

Metabones Canon EF to Sony E-Mount Smart Adapter IV ($399)
I tested both my original Metabones Smart Adapter IV and the new Metabones T Smart Adapter IV, both running fw 0.41. As stated on the Metabones website, the new T adapter has better anti-reflective interior coatings, but AF performance was identical will EVERY lens I tested (at least this offered a larger sample size). So if you have the original Smart Adapter IV and you’re happy with the anti-reflective capabilities, there is absolutely no AF performance gain by upgrading. If you’re buying new, make sure you get the latest T version.

Metabones-Smart-Adapter-IV-T
Metabones Smart Adapter IV and Metabones T Smart Adapter IV

I also tested a pair of the most popular $100 Canon smart adapters. Unlike Metabones, neither of these adapters have a USB port for firmware updates, so what you buy is what you get.

Fotodiox AF Adapter for Canon EF to Sony E-Mount ($100)
This smart adapter is my suggestion in the $100 category. While lacks user-updateable firmware port and takes a less sophisticated approach to Image Stabilization than Metabones Smart Adapter IV – it packs a lot of punch for the price.

Viltrox Auto-focus Canon EF to Sony E-Mount Adapter II ($100)
The Viltrox was my original $100 recommendation, but its build is not as good as Fotodiox – I had to re-tighten the lens mount screws several times over the course of each day and its AF is buggier and completely craps out with certain lenses.

Electronic Functions
Unless otherwise specified, these Smart Adapters provide electronic aperture control, record the lens metadata, and transmit focal length to SteadyShot.

Focus Speed
Sony a7RII offers much faster AF with the Canon lenses than the previous Sony a7 Series cameras.

Focus Modes
AF-C and AF-S are compatible

Focus Areas
Wide, Center and Flexible Spot Focus Areas are compatible

AF System Selection using Canon Smart Adapters
This is actually the most important new setting on Sony a7RII cameras. It allows users to select between 399-point Phase Detection AF or 25-point Contrast AF when using Canon smart adapters.

Menu > Custom Settings > AF System

Sony a7RII Menu Settings

The Phase Detection AF setting allows you to shoot in continuous AF-C mode with choices of Wide, Center or Flexible Spot Focus Areas. I’ve tested both AF-C and AF-S with a wide range of Sony A-mount lenses using Canon smart adapters and in all my tests I found best performance was achieved using the default setting of Phase Detection AF.

Please note that Face Detection works when compatible Canon EF-Mount lenses are used with a Canon smart adapters, but Eye-AF and Center Lock-On AF are not compatible. While the performance of many Canon EF lenses is greatly improved on a7RII, you still get the best performance and most AF features using native FE lenses.

Image Stabilization with Sony a7 Mark II Cameras
Metabones is you best choice when using Canon EF Image Stabilized lenses on Sony a7RII. Metabones Smart Adapter IV firmware 0.41 (or later) addresses Image Stabilized Canon EF lenses. With this update, users can use the lens IS switch to choose between using lens-based optical Image Stabilization and Sony a7 Mark II Series IBIS:

• If the lens IS switch is ON, lens-based optical IS is used and camera IBIS is turned off automatically.
• If the lens IS switch is OFF, the a7II camera-based IBIS takes over image stabilization.
• To turn off all IS, hold down the WO button on the adapter while switching the lens’ IS OFF.

I found that Fotodiox and Viltrox can over-compensated for image shake. I found that both camera and lens appear to adjust Pitch + Yaw when Canon IS lenses have IS switched on and when IS on the lens is switched off neither the camera and lens apply image stabilization. Essentially you get double or nothing.

Firmware on the Fotodiox and Viltrox adapters is not user-updateable. As a result, I recommend that anyone who plans to use Canon IS lenses on Sony a7II or a7RII cameras stick to Metabones.

TESTING NOTES
Smart adapters are a lot like vintage sports cars. They can run great but you simply have to expect a bit of bugginess. In the course testing there were times smart adapters don’t make proper electronic contact. If they did not make contact on first try, I remounted the adapter at least two more times.

For consistency, all testing was done under interior lighting, which is a nice midpoint between full daylight and dim-as-a-coal-mine conditions.

These tests represent performance is still photography mode and video AF will not match these results because DSLR lenses are not designed for video AF.

Here’s a look at how Canon EF-mount lenses perform on Sony a7RII using the camera’s on-sensor Phase Detection AF system with Metabones, Fotodiox and Viltrox Canon smart adapters:
