m4/3 weakness: Fast midrange zooms

In the interests of keeping size & weight under control.

12-35 f/2.8
17-50 f/2.8
35-105 f/2.8-3.5
50-150 f/4
Your first option would be my walkaround and I'd add the 20 f/1.7 and be happy almost all the time LOL. When I travel with the 5D I often carry the Tamron 28-75 f/2.8 (I have owned the really nice 24-70L for years and have carried it many times, but just got tired of the size/weight and have loved the Tammy as an alternative), add the 50 f/1.4--and maybe a wide option (I have too many, but usually the 12-24) so I can see a fastish zoom (if they can keep it reasonably small/light--otherwise I'll carry primes) with the 20 and be happy for travel.

Well, I was thinking that the primary weakness of m4/3 was that it was missing a decent fast telephoto prime. I really wish Olympus or Panasonic would make a 100 f/2.8 or a 200 f/2.8. The real promise of m4/3 was the reduction in lens size. The Panasonic 45-200 and the to be released 100-300 are both f/4-5.6 which is not that fast.

That is a wish list, right?
I started out by thinking about compromises. Fast is important, but if the size and weight get too high, it would defeat the purpose of m4/3 IMO. After all, one can adapt the superb Olympus 12-60 f/2.8-4 to m4/3 right now, but it's a large, heavy solution (more than 650g with adapter). For me, the 45-200 size/weight would be about the upper limit that I'd be looking for. So I thought "what if you limited the zoom to 3X"? Sure, it's a compromise. However, some of the most revered full-frame zooms have been in similar ranges:

12-35: 24-70mm
17-50: 35-105mm (an older, but much-used standard)
35-105: 70-200mm

Along the same lines as your Oly 14-54 thoughts -- if there was a 14-45mm f/2.8 constant aperture lens that was, say, just a little smaller than the 45-200, would anyone bite?

>superb Olympus 12-60 f/2.8-4 to m4/3

Is a very good zoom but slightly to heavy for m4/3. That is why I like the 14-54mm. Too bad that there is no IS on hte G1/GH1.
