Metabones Sony NEX to Canon Smart Mark V (updated version of Smart Mark IV) is designed to use Canon EF lenses on Sony E-mount cameras. With full camera/lens compatibility, it supports functions such as contrast and phase-detection autofocus, aperture control, and optical stabilization. If both camera and lens have stabilization systems, the adapter allows combining them via the IBIS/on button: camera on, lens on, or both on. Another “AF Lock” button can be user-assigned, with over 50 possible functions.
Metabones Smart Mark V is compatible with the Sony PXW-FS7 and can work with Cinema EOS lenses while retaining control of autofocus, aperture, and zoom. The manufacturer also confirms compatibility with Sony cameras including: A7III, A7RIII, A9, A7SII, A7RII, A7II, A7S, A7R, A7, A6500, A6300, A6000, A5000, PXW-FS5M2, PXW-FS7M2, PXW-FS5, PXW-FS7, NEX-FS700, NEX-FS100, VENICE, NEX-EA50, NEX-VG900, NEX-VG30, NEX-VG20, NEX-VG10, NEX-7, NEX-6, NEX-5R, NEX-5N, NEX-5, NEX-C3, NEX-3.
The adapter supports:
– Canon EF lenses (see Appendix)
– Canon EF-S lenses (some lenses may vignette because the adapter is designed for 1.6x crop, while Sony NEX has a 1.5x crop sensor)
– Stabilization, including 5-axis stabilization on Sony Alpha II-series cameras
– Electronic manual focus (e.g., Canon EF 85mm f/1.2L II and Canon EF 50mm f/1.0L)
– EXIF (focal length, aperture, zoom range)
– Shooting modes P, A, S, M
– Autofocus (see Appendix)
– Display of distance and zoom on VG and FS camcorder series (with lenses that support distance information)
– Automatic APS-C mode on full-frame cameras when using Canon EF-S lenses and many third-party lenses
The adapter does not support:
– Aberration corrections such as vignetting, distortion, chromatic aberration
– Continuous AF
– DMF
– Eye AF
– Attaching another adapter (e.g., some M42 adapters may physically damage the adapter)
Autofocus on Metabones adapters is supported with the following limitations:
– Fast phase-detection AF is supported only on Sony Alpha 7R II; on other Sony cameras, contrast AF with EF lenses may be very slow for moving subjects and is suitable mainly for static subjects
– Even on Sony Alpha 7R II, autofocus performance degrades significantly with long telephoto zooms as focal length increases
– On Sony Alpha 7R II, central AF points perform well, while edge/corner points may be less effective with fast lenses or telephoto lenses
– During video recording, if the subject moves you must half-press the shutter button to reactivate autofocus and reacquire the subject; due to slow contrast AF, results may be unsatisfactory
– On SONY PXW-FS7, NEX-FS700 and NEX-FS100, autofocus works only in photo mode
– The first two autofocus attempts are used for lens calibration, so the lens may fail to lock; to reacquire, half-press the shutter again
– Autofocus may struggle near the lens’s minimum focusing distance
– Lenses with hidden issues that may not appear on Canon DSLRs can show focusing accuracy issues on Sony NEX (e.g., AF mechanism lubrication issues, distance detection errors)
– Early Tamron VC lenses such as the 17–50mm f/2.8 B005 may switch poorly between OIS and IBIS modes
