Lens mount adapters, an accessory that acts as an interchangeable lens for cameras, have become quite popular in recent times. In this article, we review some of the best lens mount adapters that have gained prominence of late.
When purchasing cameras with interchangeable lenses such as single-lens and mirrorless cameras, the lens mount adapters are an important component to consider.
Lens mount adapters use a mechanism that joins the camera body to the lens. Many manufacturers create their own lens mounts according to their specifications and there is no cross-compatibility with other lenses.
7 Recommended Lens Mount Converters
Lens mount adapters is a piece of equipment that lets you fix any type of lens irrespective of its specifications. It’s a ring that’s mounted between the body and the lens.
However, even with a lens mount adapter, all lenses aren’t compatible with all cameras. Lens mount adapters are released only for those cameras with a short flange back (the distance from the mounting surface to the image sensor surface).
There are also some restrictions functionally, as it cannot be used like the original lens. Even with the help of lens mount adapters many people have the opinion that it’s hard to use.
In such circumstances, an AF compatible lens mount adapter is handy because it’s easy to handle even for beginners. Generally, when people talk about lens mount adapters, they think of the old school silver lenses.
But in this article, we’ll cover lens mount adapters for new lenses that support AutoFocus. It’s not the same as a genuine lens, but it doesn’t require complicated operations and settings and anyone can use it easily.

Sigma MC-11
Best Adapter For Canon Lens On Sony Body
Among the AF compatible lens mount adapters, one that stands out is the Sigma MC-11 released in 2016. It’s the mount that’s used to fix a Canon lens on a Sony camera.
The breakthrough of MC - 11 is that the AF operates at a quick speed with a large number of lenses, and the stability while shooting is good.
In the case of "MC - 11 EF - E" for Canon, only Canon lens made by Sigma are officially listed, but in my case, many canon lenses worked seamlessly without any problems*.
*This review is based on the experience of the author. There is no guarantee that this will work with all lenses of Canon.*
Another point to note is the frequent firmware upgrades that are done to increase compatibility and improve functions.
The quality of the product is solid. In my opinion, the MC-11 is an everyday necessity for those who have Canon and Sony E mount cameras.
A disadvantage of this mount is the size and weight of the adapter is greater than regular ones.
The focus area modes such as zone focus cannot be used. Also, please note that Canon “EF-S Lens” exclusive for APS - C cannot be physically attached to the MC - 11.

Apart from the two companies mentioned here, AF compatible mount adapters are released by various manufacturers, but many of them are products for mounting on the Sony E mount.
The reason for a large number of mounts is because of the flange back (the distance from the mounting surface to the image sensor surface).
The flange back is as short as 18 mm and other lenses can be attached easily. In order to mount the adapter, the flange back of the side of the body must be shorter than the flange back of the lens side mount.
In addition, the mount diameter on the side of the body should be larger than than the mount diameter of the lens side.
It’s also one of the reasons that Sony discloses the specifications of E mounts to third party manufacturers.
In the case of other lens mounts whose specifications aren’t publicly available, third-party manufacturers have to analyze the details of the camera and create protocols to pass information between the lens and the body seamlessly.
The AF compatible mount adapter is a convenient item that broadens the scope of the body and lens. It’s freed of the so-called "mount restraint", and free shooting becomes possible.
It’s recommended for people who own cameras from different manufacturers or those who are planning to change to another manufacturer's mount.
