In this first video blogpost I follow up on my two blogposts from 2005, I show you how easy it is to put a Pentax m42 mount lens, one of the most popular kind of lenses from the 1950s up until the late 1980s, on a Canon EOS DSLR body. Back in 2005 I used the EOS 20D, now I use the EOS 5DmkII, but it’s just as easy.

The lens I put on the camera is a Helios 85mm f/1.5, second generation, meaning that it has a 42mm screw-mount instead of the original 39mm. The adapter is a m42 EOS AF confirm adapter that you can find on eBay for around $15.
