Best telephoto lens brand and m4/3 lens vs. DSLR

I was wondering if there is a superior telephoto lens brand and if the telephoto micro 4/3rds lenses were comparable to the DSLR, i.e. Nikon and Canon. Experiences are nice, but some published references or measurements would be nice.

This site, ePHOTOzine, DPReview and many others are full of figures and test results, so have a long browse and you'll find the information you are looking for.

Modern telephoto lenses are nosltly excellent, so quality should not be an issue.

Best regards

I think that's a great question and you do need a little research to figure this out by yourself with rhis resources and some lens blogs.

I recommend any Olympus or Panasonic lens from the last five years in addition to a couple of others.
