Long lense for EOS M5!

Hi,
My Olympus E-M5 has just stopped on me and I am looking at the M5 but rather confused over lenses! With the E-M5 my 300 lens gives me a focal length of 600 I believe, so can anyone tell me what canon lens would give me that reach on the M5? I don't think there is an M lens but I understand with a canon adapter EF and EF-S lenses can be used!

The Canon Eos M5 has a Canon APS-c sensor with a crop factor of 1.6x, so if you want a reach of 600mm, you'll need a 400mm lens, with a 640mm reach. Canon offer several lenses at this focal length, from the EF 400mm F/5.6L to the heavyweights with an F/2.8 aperture, or there's the 400mm DO with an F/4 aperture.

Only a 600mm lens will give you a focal length of 600mm.

The above post is correct but i took it you are talking field of view,so as was already stated you will need about a 400mm lens to give you the 600mm FOV.

Sorry for a confusing post I sm the least technology minded person who holds a camera, I just point, twist and press and marvel if it all works! I was just of the believe that is was the sixe of the sensor in the camera that dictates that reach of the lens's so I've always felt that with my EM5 I got twice the reach as against a full sized sensor and that was why a compact super zoom camera with a tiny sensor could zoom out so far. As I say I have no technical knowledge and apologise for a confused question.

You are quite correct, the Olympus EM5 uses a sensor that is half the size of a full frame, so a 300mm lens will be comparable to the 600mm full frame lens in reach.
Confusion arises because the Canon EOS M5 uses a larger sensor, so the reach is not doubled, but only about 50% more. That is why Malcolm Stewart was suggesting a 400mm Canon lens to get the 600mm reach equivalent you had with your Olympus.
Hope this helps, the camera producers have about as murky a set of product names and component conventions as the toothpaste industry.

Sorry to be a pedant, but sensor size has nothing to do with reach of a lens, only the proportion of the image that is used.

The higher pixel density on smaller sensors compared to some full frame sensors can lead to this illusion of better reach.
