Vello LA-CEF-M42 Overview

Make the most of your existing collection of M42-mount glass with this Vello Lens Adapter that will allow you to mount these lenses to a Canon EF/EF-S-mount camera. Precise construction makes it easy to attach these adapted lenses to your camera and keeps it secure during use. Infinity focus is guaranteed, ensuring that you get proper functionality our of all your optics. Additionally, the adapter is made from a durable zinc alloy and features a matte black finish on the inside to reduce the potential for glare and reflections that can negatively impact image quality.

Although the lens will fit physically, autofocus, automatic diaphragm (AE metering), and other functions dependent on communication between camera body and lens will be disrupted by the lens adapter. You will need to focus manually, and to set exposures manually or meter in aperture priority (stop-down) mode. Focusing to infinity is retained.

This adapter enables the use of M42 lenses on Canon EF/EF-S-mount cameras, meaning you can now use your existing stable of lenses on your current camera. It is also very secure, holding the lens in place without any wobble sometimes associated with the adapting process.
Thanks to precise manufacturing, this adapter is guaranteed to provide infinity focus by placing the lens at the correct distance from the sensor. This allows you to make the most of your lenses and doesn't limit you from shooting distant subjects.
Made from a durable zinc alloy, this adapter will withstand many uses and won't wear or break in the way soft brass or cheap plastic would.

question

Is this adapter slim? I would like to adapt a Peleng 8mm fisheye to a Canon 7D to reduce vignetting. There is a Canon EF Mount version but with the cost of more vignetting. Any help on this would be appreciated. Thank you.
Asked by: Paul
This adapter is very slim and I haven't seen any vignetting on my 5DkmIV. I'd watch out for any flange that might stick out from the back of the lens - using Pentax M42 mount lenses, they have a flange for actuating the shutter and my mirror smacks it, which is not good at all. Just take a loot at the lens and if something stick out of the mounting side, I'd get a different adapter that gives you more room.

question

Does this change the lens focal length for crop sensor or full frame? Does this change the lens f stop? Thanks!!
Asked by: Anonymous
It does neither. If you are using 35mm lenses with an M42 mount they will crop according to the crop factor of the sensor of the camera you are fitting them to with this adapter. I used this adapter together with a Metabones Canon - Sony E-mount adapter too. No change in focal length other than the sensor crop factor. There is no F-stop change either. Hope this helps!

question

I bought 3 of these based on the reviews here and they are all unacceptably loose once tightened. They actually wiggle in the connection between the VELLO to Metabones adapter. (I have no issues with regular EF Canon lenses). Does anyone have the same problem?
Asked by: Bohdan
Problem is using 2 adaptors to canon body I use this with old super takumar 85 f1.8 great portrait combo very tight precise focus via live view.

question

Does this adapter have focus confirmation?
Asked by: ken
It's only a mechanical connection, with no electronic communication for focus or exposure. It's helpful for telescopes, microscopes, and other sorts of equipment and it will allow an M42 lens to be screwed into a Canon camera; but only using manual focus and exposure adjustment. That said, it's nicely machined and low profile which is what I was seeking.
