Metabones Canon EF to Sony E-mount Review

Preface

I am not an expert on camera gear. This review is purely based on my personal experience with the Metabones Canon EF to Sony E-mount adapter.

Introduction

There’s quite a few reviews out there for the adapter and all of them praising how good the adapter is. However, my experience was quite different, so I thought I would share it for the benefit of others.

Build

The build quality and material used is top notch, no surprise here, it is expected for the price Metabones is charging for the adapter.

Compatibility

Like all adapters, they’re not perfect and not all lenses work or work flawlessly. You can find a list of compatible lenses on the Metabone’s website product page.

Note: Third party zoom lens may need to be registered with the Smart Adapter first in order to detect its maximum aperture and Autofocus is disabled for most third-party lenses.

Performance

I tested the adapter with 3 different lenses; Canon 18-55 kit lens, Canon 50 f1.4, and Sigma 17-50 f2.8.

Results

Canon 18-55 kit lens worked flawlessly, autofocus speed was acceptable for general use. I wouldn’t try using it to take action/street shots that require fast autofocus though.

Canon 50 f1.4 only supported manual focus as outlined in the compatibility list on the Metabones website. Manual isn’t for everyone and me personally prefer to have autofocus for taking those moving shots.

Sigma 17-50 f2.8 is not really compatible. What I mean by this is; the first time, everything worked, all the readings were passed through to my A7s and even autofocus was working. However, on subsequent uses, everything stopped working. I could see the image in the electronic view finder and screen display, but no aperture reading and autofocus no longer worked.

Battery Life

Something I noticed is the, the adapter seems to have a huge impact on the battery. And when I was using it with the Sigma 17-50 f2.8, it was still draining the batteries, causing the camera body to become hot even after I had switched the camera off. My guess for this is the adapter is trying to, but having trouble registering the lense, refer to note above on registering third party zoom lens with the adapter.

Conclusion

I haven’t tried any other alternatives or say that the one I got was faulty. However, if you are looking to buy one, I would suggest you ensure the lenses you are planning on using with the adapter is listed in the compatible lenses list before buying. Or even better rent one and try it out first.
