Quote:Since when is the 18-150mm STM an L lens?Why do you say it has to be an L lens? What does that L add, besides weather sealing?
Oh right, a red stripe. I forgot about that...
The Fuji 18-135mm is indeed very comparable to the Canon 18-150mm, focal length range and aperture wise. It should of course be 18-202mm. Both are comparable to the Olympus 12-100mm f4, where the Olympus has an advantage at the wide end and the Canon at the long end.
The Olympus has the advantage of being weather sealed, and the Canon of being only $500 and quite a bit less heavy.
The Canon L lens has a much bigger aperture throughout the range, and has quite a bit longer tele reach too. It can best be compared with the Nikkor 28-300mm and Tamron 28-300mm, where the Canon is weather sealed and has the better optics (and the highest price by far).
