Canon RF Lens On Canon M6 Mark II
Canon M6 Mark II Camera With EF-M 18-150mm Lens
I have a m6 mark 2 camera by Canon. Is there anyway to adapt the 28-70 rf lens to my camera?
The quick answer for your question of whether you can use a Canon RF lens on a Canon M6 Mark II camera is NO. Canon's development of the differences in flange distances and mount diameters for the 3 different lens mounting systems makes it very confusing.
To understand the compatibility issues we have to look at the specific flange distances of the 3 different systems. The flange distance is the distance from the sensor to the front of the mounting flange.
The original EF and EF-S lenses are built to mount to cameras with a 44mm flange distance. The first mirrorless line of Canon bodies, the "M" series, have a flange distance of 18mm.
The newest line of Canon mirrorless cameras, the "R" series, has a flange distance of 20mm. The RF 24-70mm lens needs to be mounted at that 20mm distance from the camera sensor to function properly.
Adapting Lenses To The M6 Mark II Camera
It was easy for Canon to design adapters (essentially a spacer with electrical contacts) for the EF and EF-S lenses to mount at the proper distance from the sensors in both the M series (including the M6 Mark II) and R series of Canon mirrorless camera bodies.
It would likely be near impossible to design a 2mm thick adapter and include electrical contacts on both sides of it to get the 18mm distance extended to the required 20mm distance on an M camera like the M6 Mark II.
You'd be much better off getting an EF 24-70mm f/2.8 lens and the EF-M adapter for your M6 Mark II. It's a great lens whether you buy it new or save money with a top notch used one
Good luck and let me know how you make out.
