Techart, a lens adapter manufacturer, has announced the details of its forthcoming LM-EA9, a second-generation M-mount to E-mount adapter with built-in autofocus capabilities. This updated adapter will offer improvements over its predecessor while shrinking the form factor.

The LM-EA9 is the successor of Techart’s LM-EA7, which the company says has been its best-selling product to date. There’s no such thing as perfect though, so Techart has made a few alterations to make the new LM-EA9 even more capable.

The biggest change is the new autofocus system, which now relies on four smaller motors instead of a single large motor. This not only allows autofocus to be faster and quieter, but has also afforded Techart the ability to reduce the size of the adapter. Techart has also improved the durability of the mounting plate, which should mean less wear and tear on the mount, even when using larger lenses.

This is the size of the LM-EA7, clearly larger than the more streamlined LM-EA9.

Techart says it’s also changed the aesthetics of the adapter to better match Sony’s lineup of E-mount mirrorless cameras. Techart also notes that so long as you can adapt a lens to E-mount, you should be able to give it autofocus capabilities with this adapter.

Techart hasn’t specified the exact release date or pricing information, but we’ve contacted the company for additional information and will update this article accordingly when we receive a response.
