入魔报道：佳能1DX II将于2月2日发布

求花老给定夺一下，我现在有fe70-200，想给a7r2转接更长焦段的哪一款合适，最好400段变焦，主要拍远景，顺便打打鸟， 索尼等不上，只能转接了。

楼主，不是说7RII对300mm及以上的大炮支持不太好吗？

我之前有一个328II，最近要回到我手里了，不知道能否和7RII愉快的合体？

我用的是MB4，也很久没更新固件了~

了解，谢谢花老

当时使用的是厂家2015年9月发布的版本。

请问用的是最新版的固件么？

花老请问您有用过mb4转接佳能400/5.6么？对焦快不快？会不会经常拉风箱的说？

看过贴主的摄影经历和器材观点，

感觉你已经是资深玩家和有固定思维模式的北京的老摄友，

特别是你还喜欢购买名牌手表（穷玩车，富玩表，无论穷和富都玩相机），

所以判断你生活在北京+喜欢胶片相机（135和中画幅）+喜欢品牌手表+谨慎调研、比对，

那么我建议你可以去佳能、索尼体验店充分把玩和体验后挑选女儿和你喜欢的器材（无论购买那个品牌的都可以，去摄影城体验也是个办法），

索尼官方体验店在王府井东方新天地（靠近长安街）并且尼康的官方体验店也在附近，

佳能官方体验店在朝阳三里屯的SOHO（原来在西单，几年前搬到这里），

奥林巴斯、富士、宾得等相机可以在摄影城了解，

最后友情提醒，让女儿自己选择她自己中意的器材是最好的为父只道，父亲只提供资金和建议。

好！

《索尼A7RII佳能EF智能适配器测试》
http://briansmith_com/sony-a7rii-canon-ef-smart-adapter-tests/

《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.

Canon Metabones Fotodiox and Viltrox Smart Adapters
Fotodiox AF Adapter for Canon EF to Sony E-Mount and Viltrox AF Canon EF to Sony E-Mount Adapter II

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:
