Re: Say goodbye to 4/3 lenses.

Optical design of lenses is not alchemy.  If you want highest quality optics in a zoom, you're going to pay a price in weight of the glass and lens construction to support it.  That's why the mFT focus has been on primes instead of quality zooms.

If you want light weight in the latter you'll pay the price in it either being slower than its big brother (Pan 14-35 f2.8 and 35-100 f2.8 vs SHG's at f2.0), shorter range (Pan 14-35 2.8 vs. HG 12-60 f2.8-4) or heavier and bulkier than mFT users are believed to be willing to accept.

That Olympus is this far into mFT lens development and has yet to replace the 14-54 MkII f2.8-3.5 4/3's work horse mid-range zoom is especially telling.  The very mediocre (being polite here) 12-50 f3.5-6.3 foisted on E-M5 buyers in its stead is a very pale shadow of its forerunner.

Be happy with the primes; they're something some 4/3's were formerly also asking for.  For zooms, look no further than the HG and SHG lines for true excellence.  Now all that's needed is a body to properly support their functionality with a current sensor.
