Lens Mount Adapters: Making beautiful photography accessible


“Mount adapters” are no longer only for camera geeks

If you use a mount adapter, you can use Canon lenses on Sony cameras

 

Mount adapters, an accessory which acts as an interchangeable lens for camera, have become quite popular in recent times. In this article, we cover “AF Compatible Mount Adapters” that have gained prominence of late.When purchasing cameras with interchangeable lenses such as single lens and mirrorless cameras, the lens mount is an important thing to consider. The lens mount is 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 lens.

The Mount Adapter is a piece of equipment that lets you fix any type of lens irrespective of its specifications. It is a ring that is mounted between the body and the lens.

However, even with a mount adapter, all lenses are not compatible with all cameras. Mount Adapters are released only for those cameras with a short flange back (The distance from the mount 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 Mount Adapters many people have the opinion that it’s hard to use.

In such circumstances, an AF Compatible Mount Adapter is handy because it’s easy to handle even for beginners. Generally when people talk about Mount Adapters, they think of the old school silver lenses.

But in this article, we’ll cover adapters for new lenses that support AutoFocus. It’s not the same as a genuine lens, but it does not require complicated operations and settings and anyone can use it easily.

5 recommended AF compatible mount adapters

Mount adapters are on sale from numerous manufacturers both in Japan and abroad. The price ranges from around 1,000 yen to several tens of thousands yen

 

Among the AF compatible mount adapters, one that stands out is the Sigma MC-11 Mount Converter released in 2016. It’s the mount that is used to fix a Canon lens on a Sony camera.
Sigma MC-11 Mount Converter. The price at the company’s online shop is about 35,100 yen ($315.48). The photograph is “EF-E” for interchangeable lenses for Canon. In addition, ‘SA-E’ for interchangeable lens for Sigma SA mount is available

 

The breakthrough of the 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 as far as this author is concerned, 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.

Why are there so many adapters for E mount bodies?

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 the large number of mounts is because of the flange back (the distance from the mount surface to the image sensor surface). The flange back is as short as 18mm 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 the mount diameter of the lens side. It is for these reasons that the Sony E mount with short flange backs and large mounting diameters are sought after.

It is also one of the reasons that Sony discloses the specifications of E mounts to third part 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 is freed of the so-called “mount restraint”, and free shooting becomes possible. It is recommended for people who own cameras from different manufacturers or those who are planning to change to another manufacturer’s mount.
