Introduction<\/h2>\n

When the original Techart LM-EA7 adapter had been released it was a revelation: turning your manual focus lenses into autofocus lenses, how great is that? But there were also quirks to overcome, some reliability issues and incompatibilities with later camera models.
\nNow 5 years later there is a fully reworked, improved version. Does it solve all the issues we had with its predecessor? Let’s have a closer look at this new Techart LM-EA9.<\/p>\n

Update March 2023:<\/strong> More detailed information added how to reset the adapter if it is not working anymore, further sample images added
\n<\/em><\/p>\n

Update February 2024:<\/strong> While my adapter is still working fine I have received several reports of it breaking and very unresponsive customer support. Therefore I cannot recommend anymore to buy it, until these issues have been resolved.<\/em><\/p>\n
