Vello LAG-NEX-CEF overview

  • 1Description

Pair your existing Canon EF-mount full-frame lenses with a modern Sony E-mount mirrorless camera and experience the coveted "full-frame look" on APS-C format sensors with the Accelerator AF Lens Adapter from Vello. By using a specialized 4 element in 4 group optical design, this adapter is able to increase a lens' angle of view by a factor of 0.71x while simultaneously increasing the maximum aperture by one whole stop. This allows a 50mm f/1.4 lens on an APS-C camera to maintain an angle of view close to 50mm while providing it with an f/1.0 equivalent aperture. This setup means full-frame lenses can be adapted to APS-C sensors, or full-frame cameras in APS-C crop mode, without losing the desired natural look of a full-frame system. Along with this, the adapter features electronic coupling, enabling autofocus, auto exposure, and other functions during use.

Automatic capabilities of the lens are fully maintained, allows for auto exposure, autofocus, and aperture control from the camera body. The adapter will also transfer Exif data to the camera for appropriate tagging of metadata for easier organization and editing. Along with all of these functions the durable metal adapter sports a removable tripod foot with 1/4"-20 socket for use on a tripod or support system, alleviating strain on the lens mount. Additionally, it has a matte black interior to prevent reflections from interfering with image quality.

Note: AF function was tested for photo, video will not work properly

Vello LAG-NEX-CEF AF Comapatibility List

The following Canon lenses and Sony cameras have been tested with the Vello LAG-NEX-CEF lens adapter for photo compatibility with some operational limitations. Tests were conducted in AF-S and center point-focusing. Some Sony cameras use one or two types of focusing systems, and performance may vary.

If a lens is not listed, it might not work properly. Vello will be testing more lenses and cameras and adding them to this table, so check back for future updates and firmware upgrades.

    Vello LAG-NEX-CEF reviews

    Canon EF Lens to Sony E-Mount Camera Accelerator AF Lens Adapter is rated 3.6 out of 5 by 26.
    Rated 4 out of 5 by from Pretty good for the price. I tried this out using a NEX 7 and A7S 1. Pros: - Gain 1 stop of light - Apsc to almost full frame (when using a cropped body) - Price (lightning deal) - Less rolling shutter when using a full frame in cropped mode for video - IS - Electronic control of aperture - Packaging is pretty good, it comes with its own hard plastic case Cons: - The Autofocus really doesn't work at all for the bodies I used. It will hunt and pick a spot but will not be in focus. - Tripod mount wiggles. It's not as secure as the metabones speedbooster tripod mount - Not razor sharp wide open. If you have a bunch of EF lenses that you want to use on an NEX body AND this thing is on sale - I would totally recommend this.

    Rated 4 out of 5 by from Functions well, with a caveat for video shooters. I bought this for use on my FS7 camera. It's nice to gain the extra stop and field of view. It functions perfectly fine, but it when you change the aperture, the iris opens all the way up before changing to the new f-stop. This creates an audible noise and flashes of light as the aperture changes. This is a problem if you need to stop up or down while you are recording video. For stills and video where the lighting doesn't change it works great. I wouldn't use it for documentary shoots or reality TV where you may have to make adjustments while you are recording. Also, there is no USB port so it seems you cannot update the firmware to eliminate this issue, as was the case with the Metabones adapter.

    Rated 3 out of 5 by from ONLY FOR PHOTO NO VIDEO MODE OKAY FOR TAKING PICTURES, NO INFINITY FOCUS,TRIED ON CANON 24 70 F2.8 AUTOFOCUS WORKS ON CENTER ONLY. Mostly manual focus only with focus peaking can be fine. Night photo using canon 50 1.4 gives imaginative big circle bokeh not good stopping down to 2 will be fine, no autofocus works.
    Date published: 2017-03-14
    Rated 1 out of 5 by from Can't focus to infinity. This will be a simple review, because it was evident very clearly how poor the optics were in this adapter. While the build quality felt solid, my initial tests had me throwing this back in the box for return within minutes. It's completely unable to focus to infinity where 3 other adapters I tested were cleanly able to.
    Date published: 2017-02-28
    Rated 3 out of 5 by from A6300+canon 50 1.8 stm produce good image but autofocus is hunting at time depending on the camera autofocus settings would not buy again since its so limited on lens you can use and the constant bugs.
    Date published: 2017-05-01
    Rated 5 out of 5 by from It's worth every dollar - works with 18-35mm(starting 24mm) I brought this adapter to use it only my Sony A6500, mounted sigma 18-35mm(vignetting seen at 18mm, but starting at 24mm it doesn't appear) - Please note that AF doesn't work on this lens as it's not compatible, but you can control the aperture settings from the camera. Works perfectly fine with other lenses which were tested ex: EF 50mm f1.8 just works perfectly fine. This adapter is worth the money as it boosts out the performance from a cheap lens to a high end lens. AF will not be great in movie/video recordings but for Photos it's fine not great, but for the price point it provides almost all of the things with that EXTRA stop of light. I'm in love with this adapter. Will recommend this to friends.

    Rated 4 out of 5 by from Solid performer I'm using this with an EF 70 - 200 f2.8 and EF 24 - 105 f4 on Sony a6500. Early days yet, but it seems to work very well. The autofocus on the 70-200 is not bad. The 28-105 searches for longer, but the in camera peaking function is very helpful, and I've not had any problems with manual focussing with this lens. When using a variable ND filter, the autofocus seems to get tricked by the filter, so I've stuck with manual focus with the ND when shooting video. Overall, it the adapter does what it says it will do very well.

    Rated 2 out of 5 by from For manual focus I have canon 85mm f/1.8 on a6500 manual only, Tamron 70-200 f/2.8 auto focus. canon 50mm f/1.8 hunting. on A6000 & a7 all lens only use manual focus.
