Metabones MB-EF-E-BT5 Sony E for Canon EF MK V Mount Adapter

Metabones MB-EF-E-BT5 Sony E for Canon EF MK V Mount Adapter Lens (MINT).

Barely used adapter. I had it working perfectly on a SONY A7 iii and several Canon L lenses. It is immaculate.

Metabones MB-EF-E-BT5 Canon EF Lens to Sony E Mount T Smart Adapter (Mark V)—a mouthful of a name for a powerful little device that bridges the gap between Canon and Sony camera systems.

Metabones MB-EF-E-BT5: The Bridge Builder

1. Materials and Build Quality:

   • Metabones doesn't mess around when it comes to craftsmanship. Both the camera-side and lens-side of the adapter are precision-machined from brass and plated with chromium.
   • The satin surface finish feels just like the OEM lens and camera mounts—smooth and professional.
   • When you mount your lens on this adapter, there's no play, no gap, and definitely no wiggling. It's a snug, precise fit.

2. Compatibility Galore:

   • The MB-EF-E-BT5 is like the United Nations of lens adapters—it brings different camera systems together in harmony.
   • It allows Canon EF and EF-S lenses to play nice with Sony E-mount cameras. So if you've got a stash of Canon glass, rejoice!
   • Whether you're using a Sony A7, A9, or any other E-mount body, this adapter has your back.

3. Smooth Iris Control:

   • The adapter supports smooth iris adjustments with the latest Canon lenses (from 2009 onward), Tamron SP series lenses (2013+), and Sigma lenses (2016+).
   • No more clunky aperture changes—just seamless control.

4. Custom Function Button (Focus Hold Button):

   • Imagine having a secret button on your adapter—one that you can assign to over 50 functions. Well, the MB-EF-E-BT5 has it!
   • On Sony A1, A9, A7 series, A6500, and A6300, you can customize this button for tasks like Aperture Preview or Eye-AF.
   • It's like having a Swiss Army knife for your lens adapter.

5. SteadyShot INSIDE (IBIS) Switch:

   • Sony cameras equipped with SteadyShot INSIDE (that's their in-body image stabilization) get a dedicated switch on this adapter.
   • You decide whether to use lens-based optical image stabilization (OIS) or the camera's sensor-shift IBIS. The power is in your hands.

6. LED Indicator Magic:

   • The adapter has an LED indicator that communicates like a friendly semaphore flag.
   • It shows your operation mode, whether OIS is active, and the communication status.
   • Blink once for "ready to shoot," twice for "I'm stabilizing," and thrice for "let's chat."

7. Weather-Sealed Hugs:

   • A rubber gasket wraps around the E-mount connection, shielding it from dust and moisture.
   • It's like a little raincoat for your camera's sensitive bits.

8. Detachable Tripod Foot:

   • The adapter comes with a tripod foot that's compatible with Arca Swiss, Markins, and Photo Clam ball heads.
   • Attach it, detach it—your call. It's all about flexibility.

9. Autofocus Magic:

   • The MB-EF-E-BT5 supports various autofocus modes:
     • Fast contrast-detection AF on all E-mount cameras with most lenses.
     • Pure phase-detection autofocus on select Sony models (A1, A9, A7 series, and more).
     • Continuous video AF (in Advanced mode) for those cinematic moments.
     • Auto magnify (because sometimes you need to zoom in and check focus).
   • It's like having a camera whisperer for your lens.

10. Powered by Camera Body:

    • No external power source needed. The adapter sips energy from your camera.
    • It's efficient, like a solar panel for photons.

11. EXIF Data and More:

    • The adapter supports EXIF data transmission—focal length, aperture, and lens name.
    • Distance and zoom display on compatible Sony camcorders and mirrorless cameras.
    • Auto APS-C Size Capture for full-frame cameras using Canon EF-S lenses or third-party DX lenses.

12. Felt Material Inside:

    • The opening of the adapter is flocked with felt material to reduce internal reflections.
    • It's like a cozy nest for your lens.

13. EF and EF-S Compatibility:

    • The adapter fits both Canon EF and EF-S lenses.
    • Note that some EF-S lenses might vignette slightly due to the crop factor difference (1.6x vs. Sony APS-C's 1.5x).

In summary, the Metabones MB-EF-E-BT5 is the ultimate matchmaker for Canon and Sony gear.
