Ultimate Guide to Fullframe E-Mount Lenses

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 and Metabones T Smart Adapter IV

UPDATE: (5/10/17) Metabones T Smart Adapter V is now available (click here). It uses the same firmware as Smart Adapter IV, but with enhanced physical design.

I also tested a pair of the most popular $100 Canon smart adapters. Unlike Metabones, firmware updates are not possible with either of these adapters – 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 it appears to be running older firmware than 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.

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

UPDATE: (5/10/17) Unlike Metabones, neither of these adapters support firmware updates, but Fotodiox has released an updated version of their Canon EF to Sony E-Mount Adapter (click here)

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

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. UPDATE: (5/10/17) Metabones T Smart Adapter V is now available. It runs the same firmware as IV, but with enhanced physical design. 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, a7RII or a7SII cameras stick to Metabones.

Please note that in-lens IS or VC pulls needed power from the adaptor, so the trick is to switch IS or VC OFF and allow the a7 Mark II SteadyShot to do the work. (This is not the case with E-mount OSS lenses – go ahead and turn OSS on)

Video AF Performance

These tests represent AF results for still photography mode. Video AF will not match these results because unlike E-mount lenses which are designed to perform well in both Still and video, DSLR lenses are not designed for video AF.

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 dimmer-than-a-coal-mine.

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:

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.

I’ve received so many questions about lens compatibility of Canon EF Smart adapters on Sony E-Mount cameras including Sony a7, a7R, a7S, a7II, a6000, a5100, a5000 and NEX mirrorless cameras that I headed to B&H Photo where I knew I could find a huge selection of Canon EF lenses to put to the test.

To compile this Guide to Canon Smart Adapter lens compatibility on Sony a7 Series E-Mount cameras, I tested every Canon EF lens I could get my hands on using these Canon Smart Adapters:

UPDATE: My tests with Sony a7RII, a7II (fw 2.00 and later), a6300 & a6500 show they allow AF-C continuous auto-focus in still mode plus much faster AF with the Canon lenses that I’ve tested.

UPDATE: READ MY SONY a7RII CANON SMART ADAPTER TEST

Metabones Smart Adapter IV | Fotodiox AF Canon to Sony E Adapter | Viltrox AF Canon to Sony E Adapter

• Metabones Canon EF to Sony E-Mount Smart Adapter IV ($400)
• Fotodiox AF Adapter for Canon EF to Sony E-Mount ($100)
• Viltrox Auto-focus Canon EF to Sony E Mount Adapter II ($100)

Please Note: Since these tests were performed, Metabones has updated their firmware many times. The Fotodiox and Viltrox adapters listed here cannot be updated – so if you can’t afford Metabones, I’d recommend the newer FotodioX Canon EF Lens to Sony E-Mount Camera Pro Fusion Smart AF Adapter ($100)

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 a7, a7R, a7S, a7II and other existing Sony E-mount mirrorless cameras offer AF-S autofocus speed that’s acceptable at best – but never fast – with the Canon EF Smart Adapters tested in this review. AF speed is well suited for landscapes, architecture and portraits – but when it comes for fast moving action, fuggedaboutit!

Image Stabilization with Sony a7 Mark II Cameras

In addition to AF, I also wanted to see how Canon IS image-stabilized lenses would interact with the 5-Axis IBIS system found in the Sony a7II and a7RII. Unlike when Sony E-mount OSS lenses are mounted on a7 Mark II cameras and IBIS allows the lens to control Pitch + Yaw and the camera controls the other functions. In my initial tests, I found that Fotodiox, Viltrox and Metabones (firmware 0.40) over-compensated for image shake. Both the camera and lens appear to adjust Pitch + Yaw when Canon IS is switched On, but when IS on the lens is switched off neither the camera and lens apply image stabilization. Essentially you get double or nothing.

Metabones was aware of this issue and on June 1st,they released Metabones firmware update 0.41 for Smart Adapter IV to address this. With this update, users can use the lens IS switch to choose between using lens-based optical Image Stabilization and Sony a7II 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.

Firmware on the Fotodiox and Viltrox adapters is not user-updatable. (In fact, both appear to be running out-dated Metabones III firmware) As a result, I recommend that anyone who plans to use Canon IS lenses on Sony a7II or a7RII cameras stick to Metabones.

In the course of these tests I noticed that smart adapters occasionally don’t make proper electronic contact, so in cases they did not make contact on first try, I remounted the adapter at least two more times. Consider this fair warning that results may vary. Now without further ado is my ultimate guide to Canon lens compatibility using Metabones, Fotodiox and Viltrox Smart Adapters:

CANON EFS LENSES

Canon EFS lenses are APS format with a very hard vignette edge making them suitable for Sony APS cameras like a6000, a5100, a5000 and NEX – but will only cover APS-crop mode on a7-series cameras.

Fullframe crop shows a hard edge vignette with Canon EFS lenses.

ZEISS ZE LENSES

Conclusion:

Each of the three adapters performed slightly better with certain lenses yet the overall performance was fairly comparable. The $100 adapters from Fotodiox and Viltrox look identical but the results while close were not identical so it’s possible they are idenical in construction but with different firmware. I had to tighten the lens mount screws on the Viltrox repeatedly over the course of testing. If this happens to you I suggest applying a dab of Loctite on the screw threads (clear nail polish will do in a pinch) then tightening down firmly with a jewelers Phillips head screw driver.

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.
