When the 40-150/F2.8 is announced...

So the spec for 12-40mm has been out

- Linear motor, MSC mechanism, AF inner focus
- Manual focus clutch mechanism
- 20cm minimum focusing distance (maximum magnification of 0.3 times, 35mm equivalent 0.6 times) throughout the entire zoom range
- Dust-proof drip
- Filter size: 62mm
- Total length: 84mm, maximum diameter 69.9mm
- Weight: 382g
- late November release

Panasonic 12-35mm F2.8
- 25cm minimum focusing distance (maximum magnification of 0.17 times, 35mm equivalent 0.34 times)
- Weathersealed
- Filter size: 58mm
- Total length: 73.8mm, maximum diameter 67.6mm
- Weight: 305g

12-40mm being being more larger/heavier than 12-35mm and come without OIS, should make Pana user and maybe some Oly user sticking with 12-35mm instead for the size and without looking ridiculous on their camera.

Though the magnification of 12-40 screams Macro to me, that is even higher than Voigtlander's 0.25x/0.5x magnificaiton which I found to be plentiful for my need without getting dedicated Macro lens.

I'm interested in the 12-40, but only when the lens "set" is available. I currently have the 7-14, 12-35 and 35-100 which is a very functional cohesive set of lenses. I likely won't purchase until at least the 40-150/F2.8 is announced. The problem with a mixed set of lenses is the difference in zoom/focus direction between Oly/Panny. Honestly, I wish that had been agreed to as a part of the standard...

I'm very happy with my panny "holy trinity", but if the Olympus offers better image quality, it will be hard to ignore - especially with the added range. My only hope is that the 40-150/F2.8 is small enough to compare with the 35-100 - even if it had to be a 40-150/F2.8-4 lens (maintaining F2.8 from 40-100 at a minimum).

No matter what, I'm excited to see what the E-M1 has to offer...
