Why hasn't Panasonic or Olympus come out with a faster lens in a focal length like 70-200? It seems to me this would play to the strengths of the micro four thirds format. Sure, it is a bit of an odd zoom range if you compare to FF equivalents, but why not? Longer reach of the lenses is why I like the idea of m43 with it's 2x crop in the first place. I own the P35-100 2.8 and find it great but too short. I also recently purchased the P100-300 and I am underwhelmed with the quality (maybe I have poor technique, maybe I have a bad copy..), and speed. I also realize I am usually ok to get to around 200mm. The Olympus 40-150 is still too short, and since I have a Panasonic body, the lack of OIS is pretty much a deal killer for me as well. Heck, I'd be happy if Sigma just put a m43 mount on their excellent 70-200 2.8. They have made some other m43 lenses in the past, so that would be great. It also has OIS. With a m43 native mount one would also get AF. I'll probably wait a while to see if anyone steps up, otherwise, I may bite the bullet and get a Metabones m43-canon adapter (electronic) and a Sigma. It will suck a bit not to have AF, but I suspect for the kind of shots I take, it would be workable. Anyone else vote for a fast 70-200 lens though??
